Answer:
r = 4
Step-by-step explanation:
You need to use the slope formula to solve for r.
1. Write out the equation using slope formula
(-7 - 1)/(r + 4) = -1
2. Multiply both sides by r + 4
-8 = -r - 4
3. Add 4 on both sides. Optionally, use the reflexive property of equality.
-r = -4
4. Multiply both sides by -1
r = 4
Answer:
Step-by-step explanation:
Let's assume that the length of a side of Allison's room as x
So, Lindsey's room = x + 3
If Lindsey's room needs 225 sq. feet of carpeting, then x + 3 = 
So, x + 3 = 15
Therefore, x = 15 - 3 = 12 ( So, Allison's room has a side of length 12)
Therefore, the carpeting needed = 12 × 12 = 12² = 144 sq. feet
There's your answer!
Answer:
252cm
Step-by-step explanation:
18/2=2
9*14=126
126*2=252
0.916666666... the 6 continues... if you need to rounded by the hundreds place, 0.917 or by the tenths, 0.91. Hoped I helped!
Answer:
$9
Step-by-step explanation:
If you do 3.5*4 then you get 14. You then use the $5 gift card so you subtract 5 from 14 and get 9
using the equation, that would be f(x) = (3.5*4)-5. Using PEMDAS, you would do the parenthesis first so it would be f(x) = 14-5 which equals 9
