Which expressions are equivalent. Circle your answer.
a. 10x - 6x
b. 7x + 3x
C. 12x + 2x - 10x
d. X - X + 2x
Answer: a) 10x-6x and c) 12x+2x-10x
Step-by-step explanation:
Lets start by simplifying all the expressions
a) 10x-6x=4x
b)7x+3x=10x
c)12x+2x-10x=14x-10x=4x
d)x-x+2x=2x
As you can see a and c both simplify to 4x meaning that is our answer.
Options A and C
Solution:In order to simplify these expressions, we should combine like terms:10x-6x=4x7x+3x=10x12x+2x-10x=14x-10x=4x (so expressions A & C are equivalent)x-x+2x=0x+2x=2xHope it helps.

Approximately how many
years would it take for an
investment of $1,000 to grow
to $1,500 with a simple
interest rate of 8%?
Answer:
6.25 years
(6 years 3 months)
Step-by-step explanation:
Simple interest formula
A = P(1 + rt)
where:
A = final amountP = principalr = interest rate (in decimal form)t = time (in years)Given:
A = $1,500P = $1,000r = 8% = 0.08Substitute given values into the formula and solve for t:
⇒ 1500 = 1000(1 + 0.08t)
⇒ 1500 = 1000 + 80t
⇒ 500 = 80t
⇒ t = 6.25 years

Question is on the screenshot.
An individual is selling tickets for a new movie that just came out. The first night the individual sold 45 Senior tickets and 92 Adult tickets. The second night, the individual sold 26 Senior tickets and 45 Adult tickets. Which night did the individual sell a higher ratio of Senior tickets to Adult tickets?
Step-by-step explanation:
the ratio senior to adult tickets on the first night :
45/92
the ratio on the second night :
26/45
which ratio is higher ? that means we have to determine which fraction is bigger.
the simplest and fastest way to compare them is to bring them to the same denominator (bottom part).
and the simplest way to do that is simply by multiplying the numerator and denominator of each fraction by the denominator of the other fraction :
45/92 × 45/45 = 2025 / 4140
26/45 × 92/92 = 2392 / 4140 (this is therefore bigger)
so, the ratio on the second night is higher.
When "b" = 6, solve for "a" using the following formula: a2 = 2b + 1
Answer:
sqrt(13)
Step-by-step explanation:
Assuming by a2 you mean a squared:
a^2=2b+1
a^2=2(6)+1
a^2=13
a=sqrt(13)
(if by a2 you mean 2*a then a=6.5)
a ball is thrown vertically upward from the ground. it's distance in feet from the ground in t seconds is s=-16t+224t. after how many seconds will the ball be 768 feet from the ground? pls help!!!
Answer:
3.692seconds
Step-by-step explanation:
distance s is represented by the following equation s=-16t+224t
given the distance=768ft
replace s by 768 in the equation to find t (time):
768=-16t+224t
768=208t
t=768/208 =48/13 =3.692seconds

If you can buy 15 bags of potatoes for $20, then how many can you buy with $4?
Answer:
Step-by-step explanation:
15 bags for $20 can be represented with 15/20
so x bags for $4 can be represented with x/4
now if you proportion it out (ricochet), 4x15 is 60, 60 divided by 20 is 3, so you can buy 3 bags of potatoes with $4.
OR
you could do 15/20 is 0.75
0.75 times 4 is 3, so $4 can buy you 3 bags.
Answer:
Step-by-step explanation:
Remark
This is a proportion problem. It assumes that if you know 3 of the four parts of a 2 ratio proportion, you can solve for the 4th one.
Givens
number of bags = 15
Cost = 20
Different cost = 4
number of bags = ?
Formula
Number of bags / Cost = different number of bags/ New Cost
Solution
15/20 = x / 4 Multiply both sides by 4
15*4/20 = x / 4 * 4
60/20 = x
Answer x = 3
That is 4 dollars gets you 3 bags of potatoes

3x = 0.5x2

B. x = -4 or x = 3
C. x = -2
D. x = 1.5 x = 0 or x = 6
PT.2
0 = 5x2 - 2x + 6
A. x= 1±3i/2
B. x=1±√11/5
C. x=1±I√29/5
Answer:
the answer to pt 1 is D. x=1.5 x=0 or x=6
and the answer to part 2 is C. x=1±I√29/5
Step-by-step explanation:
1. The solution of this equation is x = 0 or x = 6 which is option D.
2. The solution of this equation is [tex]x = \dfrac{1 \pm i\sqrt{29}}{5}[/tex] which is option C.
Use the concept of quadratic equation defined as:
The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations.
The quadratic equation has the following generic form:
ax² + bx + c = 0
1. The given quadratic equation is,
3x = 0.5x²
Rearranging it,
0.5x² - 3x = 0
Common out x,
x(0.5x - 3) = o
Then we have,
x = 0 or,
0.5x - 3 = 0
Add 3 on both sides,
0.5x = 3
Divide both sides by 0.5,
x = 3/0.5
x = 6
Hence the solution of this quadratic equation is,
x = 0 and x = 6 which is option D.
2. The given quadratic equation is:
0 = 5x² - 2x + 6
It can be written as,
5x² - 2x + 6 = 0
Since we know the quadrature formula for ax² + bx + c = 0 is,
[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
Here we have,
a = 5
b = -2
c = 6
Substitute values into the formula,
[tex]x = \dfrac{2 \pm \sqrt{4 - 120}}{10}\\\\x = \dfrac{1 \pm i\sqrt{29}}{5} \text{ }\text{ \text{ }} \text{\text{ }\ since } \sqrt{-1} = i[/tex]
Hence, option C is correct.

Find the equation of a line that passes through the point (4,2) that is perpendicular to the line y=(4/3)x
Answer:
Step-by-step explanation:
Hello:
an equation for the line is : y =mx +b (m: is a slope )
perpendicular to the line described by : y = 4/3 x
So : product for two slopes = -1 means : m×4/3=-1
m = -3/4
now : y = -3/4 x+b
but this line :
through the point (4,2) : 2 =(-3/4)(4)+b....... b=5
conclusion :
the equation is : y = -3/4x +5

|3x-4(x+1)|=2
Answer:
x = -6 or x = -2
Step-by-step explanation:
|3x-4(x+1)|=2
Simplify inside the absolute value by distributing
|3x-4x-4|=2
Combine like terms
|-x-4|=2
Now separate into two equations, one positive and one negative
-x-4 = 2 or -x-4 = -2
Add 4 to each side
-x-4+4 = 2+4 or -x-4 = -2+4
-x = 6 or -x =2
Multiply by -1
x = -6 or x = -2

how long would it take an investment of $25000 to amount to $40 000 at a flat rate of 9.5% per annum?
Answer:
it will take approximately 6.32 annum(years) to reach $40000
Step-by-step explanation:
9.5% of $25000 = $2375
$40000 - $25000 = $15000 so you need to make an interest of $15000 overall to reach $40000
since you make $2375 each year therefore
$15000 ÷ $2375 will give you the number of years to reach $40000
hence 15000 ÷ 2375 = 6.315
approximately = 6.32 annum(years)
12y – 2x = 12
slope intercept form
Answer:
Step-by-step explanation:
12y = 2x + 12
y = 2/12x + 12/12
y = 1/6x + 1
The slope intercept form is y = (1/6)x + 1.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
12y - 2x = 12
The slope intercept form is y = mx + c.
So,
12y - 2x = 12
Add 2x on both sides.
12y = 12 + 2x
12y = 2x + 12
Divide both sides with 12.
y = (2/12)x + (12/12)
y = (1/6)x + 1
Thus,
The slope intercept form is y = (1/6)x + 1.

A bag of candy contains 50 pieces of candy. The flavors are orange, strawberry, apple and
lemon. You know there are 12 orange candies. You pick an orange, put it back because you don'tlike orange and then pick a strawberry. The probability of this happening is 9/125. How many
strawberry candies are there?
Answer:
15
Step-by-step explanation:
Let the probability of picking an orange = P(O), and the probability of picking a strawberry = P(S),
Based on the question, he picked an orange first and the probability of picking that is
P(O) = 12/50
Then he picked a strawberry on the second pick, the probability of picking the strawberry is P(S) and we'll find that later.
The probability of picking orange then strawberry with replacement is
P(O) × P(S) = 9/125
Substitute the P(O)=12/50,
12/50 × P(S) = 9/125
P(S) = 3/10
Then by finding the number of strawberry candies, we'll just have to multiply P(S) with the total number of candies, i.e.
Number of strawberry candy
= 3/10 × 50
