Answer:
x = 1.6 or [tex]\frac{8}{5}[/tex]
Step-by-step explanation:
12x - 11 = 2x + 5
Add 11 to both sides,
12x - 11 + 11 = 2x + 5 + 11
12x = 2x + 16
Subtract 2x from both sides,
12x -2x = 2x - 2x + 16
10x = 16
Divide both sides by the same factor (in this cas the factor is 10),
[tex]\frac{10x}{10} =\frac{16}{10}[/tex]
[tex]x=\frac{8}{5}[/tex]
x = 1.6 or [tex]\frac{8}{5}[/tex]

The sum of two numbers is 21. Their product is 108. What are the two numbers?
Answer:
9 and 21
Step-by-step explanation:
First we can write the factors of 108:
1,108
2,54
3,36
4,27
6,18
9,12 - these 2 numbers add up to 21 so these 2 numbers is our answer.
Answer:
12 and 9
First, divide 108 by a relatively low number, 12[tex]108 / 12 = 9[/tex]
Now that we have 9, multiply 9 by 12[tex]9 * 12 = 108[/tex]

Find the measure of each angle.
x - 7
X
x + 10
Answer:
x - 7: 52
x: 59
x + 10: 69
Step-by-step explanation:
Since we have a straight line, we know that the angles must add up to 180. We can set up an equation to solve:
x - 7 + x + x + 10 = 180
Combine like terms:
3x + 3 = 180
Subtract 3 on both sides:
3x = 177
Divide by 3 on both sides:
x = 59
Now plug in 59 for each angle.
The "x - 7" angle should equal 52, the "x" angle should equal 59, and the "x + 10" angle should equal 69.
Answer:
52°, 59°, and 69°
Step-by-step explanation:
Each of these angles add up to make a straight line, or = 180°
(x - 7) + x + (x + 10) = 180
3x + 3 = 180
3x = 177
x = 59
Angle A = 52°
Angle B = 59°
Angle C = 69°
52 + 59 + 69 = 180!

Edward counted out 20 cards for a card game. Then he split those cards evenly among the 4 players.
The letter c stands for the number of cards for each player. Which equation can you use to find c?
option
20-4=C
20/4=C
Answer:
20/4=c
Step-by-step explanation:
You can tell that that is the right answer, because 20-4=c means that each person would get 16 cards, and if you multiply that by 4(the amount of people that are playing) It's way more than 20 cards, so you know that 20/4=c is the right answer. Hope that helped;)
If the labor force is 740 workers, but 27
are unemployed, what is the
unemployment percentage?
A. .36%
B. 3.6%
C. 36%
D. 360%
Answer:
3.6% or B quack quack quack quack
The unemployment percentage is 3.6 percent. Therefore, option B is the correct answer.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, the labor force is 740 workers, but 27 are unemployed.
Here, percentage = 27/740 ×100
= 2700/740
= 3.6%
Therefore, option B is the correct answer.

find, w: x: y: z:
Answer:

Finding w and x [both are equal]
Take the cos function of one of the 45° angles, which is the ratio of the adjacent side to the hypotenusecos(45°) = [tex]\frac{1}{\sqrt{2} } = \frac{w}{6}[/tex]⇒ w = [tex]\frac{6}{\sqrt{2} } = \frac{6}{\sqrt{2} } *\frac{\sqrt{2} }{\sqrt{2} } = \frac{6\sqrt{2} }{2}[/tex]⇒ w = 3√2 and x = 3√2Finding y

Find the area of the rhombus.
Step-by-step explanation:
as the graphic shows, we are dealing with a special rhombus : a square.
this is proven by the fact that the angle on one side of the diagonal at the corner is 45°. so, the other side must be 45° too, and so we have 90° angles at the corners.
what is not clear to me is : what is 6 cm long ? a half-diameter, or the whole diameter ?
I assume the half-diameter.
what the graphic is trying to suggest is that we have 4 little right-angled triangles that are also isoceles triangles (their legs are equally long).
every leg is 6 cm long (based on my assumption above).
because they are right-angled, the area of each of these little triangles is leg×leg/2
6×6/2 = 18 cm²
we have 4 triangles, so the total area is
4×18 = 72 cm²
if 6 cm stands for the whole diagonal after all, then the only change is the length of the legs, which would be then 6/2 = 3 cm.
then we would have
3×3/2 = 4.5 cm² for a single triangle
and
4×4.5 = 18 cm² for the whole area.

Raul is a saver. He sets aside $100 per month during his career of 40 years to prepare for retirement. He does not like the idea of investing because he prefers to minimize his risk as much as possible, so he puts his money in a savings account which earns 1.5% interest per year.
The total balance in Raul's account after 40 years when he retires is $65,714.90.
What is the total balance?The formula that can be used to determine the balance of the accout is: monthly amount saved x annuity factor.
Annuity factor = {[(1+r)^n] - 1} / r
Where:
r = interest rate = 1.5/12 n = number of periods = 12 x 40 = 480$100 x [(1.00125^480) - 1 ] / 0.00125 = $65,714.90

Phillipa rode her bicycle every day over the weekend. Phillipa rode [(13.5 + 8.5) ÷ 2]
miles on Friday, [18 − (2 × 4)] miles on Saturday and [20 − (5 − 3)]
miles on Sunday.
On which day did Phillipa ride her bicycle the most?
She rode her bicycle the most on .
Answer:
Sunday
Step-by-step explanation:
Friday
[(13.5 + 8.5) ÷ 2] = [(22) ÷ 2] = 22 ÷ 2 = 11 miles
Saturday
[18 − (2 × 4)] = 18 - (8) = 18 - 8 = 10 miles
Sunday
[20 − (5 − 3)] = 20 - (2) = 18 miles
18 > 11 > 10

Answer:
1. 20 km/hr (60km / 3h)
2. 70 m/hr (170m / 2h)
3. 6.5 hr (260cm / 40km)
4. 4.5 s (72cm / 16cm)
5. 184 km (46km * 4h)
Step-by-step explanation:
We'll use d = distance, t = time, s = speed.
Speed over time can be found by dividing distance by time
s = d / t
We can take this formula and manipulate it to find either distance or time if we know two of the values. Keeping in mind division and multiplication cancel each other.
If we wanted to find d for instance we can multiply both sides by t to get
s * t = d
For time we can divide both sides of the above formula by s to get
t = d / s
Answer:
1. 20 km/h
2. 70 m/h
3. 6.5 h
4. 4.5 s
5. 184 km
Step-by-step explanation:
For first two questions, you can use the following formula:
[tex]\displaystyle \large{s = \frac{d}{t}}[/tex]
I denote ‘s’ be speed, ‘d’ be distance and ‘t’ be time. Some books may use ‘v’ for speed instead of ‘s’ but I use ‘s’ variable instead so it makes the equation easier to memorize.
Therefore, speed = distance/time
( 1 ) The first question is given both distance be 60 km and time be 3 hours. Therefore:
[tex]\displaystyle \large{s=\frac{60}{3}}\\\displaystyle \large{s=20 \ \ \sf{km / h}}[/tex]
So for the first question, the speed is 20 km/h
( 2 ) The second is given both distance be 140 m and time be 2 hours. Therefore:
[tex]\displaystyle \large{s=\frac{140}{2}}\\\displaystyle \large{s=70 \ \ \sf{m / h}}[/tex]
Therefore, speed is 70 m/h
For the third and four questions, we will be finding time. From the speed formula:
[tex]\displaystyle \large{s=\frac{d}{t}}[/tex]
Multiply both sides by t.
[tex]\displaystyle \large{st=d}[/tex]
Divide both sides by s.
[tex]\displaystyle \large{t=\frac{d}{s}}[/tex]
Therefore, time = distance/speed
( 3 ) The question is given speed be 40 km/h and distance be 260 km. Therefore:
[tex]\displaystyle \large{t=\frac{260}{40}}\\\displaystyle \large{t=\frac{13}{2} \ \ \sf{h}}\\\displaystyle \large{t = 6\frac{1}{2} \ \ \sf{h}}\\\displaystyle \large{t= 6.5 \ \ \sf{h}}[/tex]
Therefore, time is 6.5 h
( 4 ) The question is given speed be 16 cm/s and distance be 72 cm. Therefore:
[tex]\displaystyle \large{t=\frac{72}{16}}\\\displaystyle \large{t=\frac{9}{2} \ \ \sf{s}}\\\displaystyle \large{t=4\frac{1}{2} \ \ \sf{s}}\\\displaystyle \large{t=4.5 \ \ \sf{s}}[/tex]
Therefore, time is 4.5 s
For the last question, we have to find distance. From the speed formula:
[tex]\displaystyle \large{s=\frac{d}{t}}[/tex]
Multiply both sides by t.
[tex]\displaystyle \large{st=d}\\\displaystyle \large{d=st}[/tex]
Therefore, distance = speed * time
( 5 ) The question is given time be 4 hours and speed be 46 km/h. Therefore:
[tex]\displaystyle \large{d=46 \cdot 4}\\\displaystyle \large{ d=184 \ \ \sf{km}}[/tex]
Therefore, distance is 184 km.

Step-by-step explanation:
Stacy- ratio of oat to blueberry is 6:2 we want to find x:10
10 is 5 times 2, and whatever you do to the bottom you have to do to the top, and 6 times 5 is 30
Naomi- ratio of oat to blueberry is 9:5 we want to find x:10
The 10 is 2 times 5, and whatever you do to the bottom you have to do to the top, and 9 times 2 is 18
