Answer: 8
Step-by-step explanation:
QS = RS + QR
3x = 2x + 3x-8
3x = 5x - 8
8 = 2x
8/2 = x
4 = x
RS = 2x = 2(4) = 8
Answer:
5
Step-by-step explanation:
I <em>think</em> 5 sorry if I am wrong
17/25 = 68/100 33/50 = 66/100 15/20 = 75/100
The perimeter is all the side lengths added up.
Add up all the side lengths:
6x - 4 + 6x - 4 + 12x + 3 + 12x + 3 + 14x + 13
Add all like terms.
50x + 11
The answer is C) 50x + 11 units
Answer:
Smoothie = 3
Ice cream = 1.5
Step-by-step explanation:
2s + i = 7.5
3s + 2i = 12
subtract the equations
(3s + 2i) - (2s + i) = s + i
s + i = 4.5
2s + i = 7.5, so s must equal 3 (7.5 - 4.5)
If s = 3, then i is 1.5 (4.5 - 3.5)
To check, plug 3 and 1.5 into s and i.
2(3) + 1.5 = 7.5
6 + 1.5 = 7.5
7.5 = 7.5
3(3) + 2(1.5) = 12
9 + 3 = 12
12 = 12
