13 – 3r =-26
Answer:
r = 13
Step-by-step explanation:
-3r=-26-13
-3r=-39 divide by 3
r=13
Step-by-step explanation:
13 - 3r = -26
13 − 3r −13 = −26 − 13
−3r=−39
divide by 3
r = 13
The length of a rectangle is eight more than twice its width. The perimeter is 88 feet. Find the dimensions of the rectangle.
A w = 10 ft, l = 18 ft
B w = 16 ft, l = 28 ft
C w = 18ft, l = 24 ft
D w = 12 ft, l = 32 ft
Answer:
D w = 12ft, l = 32ft
Explanation:
Make an equation for your length based on the given information.
l = 2w + 8
Make an equation using what you know about the perimeter
p =2l + 2w, p = 88
88 = 2l +2w
Substitute in your previous equation for l.
88 = 2(2w + 8) + 2w
Distribute and simplify.
88 = 4w + 16 + 2w
88 = 6w + 16
72 = 6w
w = 12
Now you can solve for l using the first equation.
l = 2(12) + 8
l = 32
Your answer is w = 12fr, l = 32ft. You can check your work by plugging the values back into the perimeter equation.

Answer:
B
Step-by-step explanation:
AB and CD are the same length, so the construction will be one that shows addition of same-length segments. In choices A and C, XY > YZ. In choice D, XY < YZ. Only choice B shows addition of same-length segments.
As a check, you can compare the length of AB or CD to XY or YZ. You will find they are approximately the same, as they should be.
Hannah took six quizzes in math. She scored 4 twice, 6 once, and 8 three times. What ja Hannah’s average for the six math quizzes?
Answer:
Option H. 6⅓
Step-by-step explanation:
Let X be the score.
Let F be the number of scores (i.e the frequency)
From the question given above, the following data were obtained from:
X >>>>>>>>> F
4 >>>>>>>>> 2
6 >>>>>>>>> 1
8 >>>>>>>>> 3
Thus, we can obtain the average as follow:
X >>>>>>>>> F >>>>>>> FX
4 >>>>>>>>> 2 >>>>>>> 8
6 >>>>>>>>> 1 >>>>>>> 6
8 >>>>>>>>> 3 >>>>>>> 24
Summation (FX) = 8 + 6 + 24
Summation (FX) = 38
Summation (F) = 2 + 1 + 3 = 6
The average = summation (FX) /Summation F
The average = 38/6
The average = 6⅓
Therefore, Hannah's average for the six math quizzes is 6⅓.

A gamestop you can buy a xbox one foe 150.00 and each game to go with it would cost 24.00 or you can buy a playstation 4 for 180.00 abd esch game for 20.00
Answer:
Let's write two linear equations:
For the Xbox, we have:
Price per console (you pay it only once) = $150.
Price per game = $24
Then, the total price if you buy x games, you have:
P1(x) = $150 + $24*x
For the Playstation we have:
Price per console (again yo pay it only once) = $180
Price per game = $20
So if you buy x games, the total price is:
P2(x) = $180 + $20*x.
Now, we can find the number x such that both prices are equal
P1(x) = P2(x)
$150 + $24*x = $180 + $20*x.
let's solve this for x.
$24*x - $20*x = $180 - $150
$4*x = $30
x = $30/$4 = 7.5
What does this mean?
If you buy less than 7.5 games (7 or less) then the Xbox will be cheaper, because the y-intercept is smaller.
If you buy more than 7.5 games (8 or more) then the Playstation will be cheaper, because the price per game is smaller.

Answer:
m[tex] \angle[/tex]6 = 68°Step-by-step explanation:
From the question all the angles are on a a straight line which means the sum of their angles is 180 and one of the angles is 90°
So to find m [tex] \angle[/tex] 6 , add
m [tex] \angle[/tex] 5 and 90 and subtract the result from 180°
That's
m[tex] \angle[/tex]5 + m[tex] \angle[/tex]6 + 90 = 180
m[tex] \angle[/tex]6 = 180 - 90 - m[tex] \angle[/tex]5
m[tex] \angle[/tex]6 = 180 - 90 - 22
We have the final answer as
m[tex] \angle[/tex]6 = 68°Hope this helps you
In the question, a lines & angles diagram is provided, and we can see three angles labelled here. The angles are angle 5, angle 6 and a 90°.
GiveN,
Angle 5 = 22°One of them is 90°We have to find the measure of the missing angle 6...
All the three angles are lying on a staright line, so their collective measure or the sum of these 3 angles is equals to 180°.
➝ Angle 5 + Angle 6 + 90° = 180°
➝ 22° + Angle 6 + 90° = 180°
➝ Angle 6 + 112° = 180°
➝ Angle 6 = 68°
So, the measure of Angle 6:
[tex] \huge{ \boxed{ \bf{68 \degree}}}[/tex]
And we are done !!

Answer: The answer is 3.10
Step-by-step explanation: Fisrt of all you add 25+7 which gives you 32. Add 32 and 55, gives you 87. You need to figure out w and b is 270. So 270 divided by 87 is 3.10. So you need 3.10 weeks.
Jesse runs a 26-mile race in 5 hours. LJ runs a 15-mile race in 2 hours. Who runs at a slower rate?
Answer: Jesse
because i guess i divided the number you could do it however 15 divided by 2 = 7.5 and 26 divided by 5 = 5.2
Answer:
Jesse is the slower rate.
Step-by-step explanation:
The slower rate is going to be determined by the distance divided by the time.
Jesse: 26 / 5 = 5.2 miles / hour
LJ: 15 / 2 = 7.5 miles / hour
Jesse is the slower rate.

what does 5/8 x 30 1/2 = in mixed number form
Answer:
19 1/16
Step-by-step explanation:
Answer:
305/16
Step-by-step explanation:
Simplify the following:
(5 (30 + 1/2))/8
Hint: | Express (5 (30 + 1/2))/8 as a single fraction.
(5 (30 + 1/2))/8 = (5 (30 + 1/2))/8:
(5 (30 + 1/2))/8
Hint: | Put the fractions in 30 + 1/2 over a common denominator.
Put 30 + 1/2 over the common denominator 2. 30 + 1/2 = (2×30)/2 + 1/2:
(5 (2×30)/2 + 1/2)/8
Hint: | Multiply 2 and 30 together.
2×30 = 60:
(5 (60/2 + 1/2))/8
Hint: | Add the fractions over a common denominator to a single fraction.
60/2 + 1/2 = (60 + 1)/2:
(5 (60 + 1)/2)/8
Hint: | Evaluate 60 + 1.
60 + 1 = 61:
(5×61/2)/8
Hint: | Express 5×61/2 as a single fraction.
5×61/2 = (5×61)/2:
((5×61)/2)/8
Hint: | Express ((5×61)/2)/8 as a single fraction.
((5×61)/2)/8 = (5×61)/(2×8):
(5×61)/(2×8)
