Answer:
Is seven times the difference of a number and 4 no more than 10?
Answer:
x=9
Step-by-step explanation:
1. distribute the 3 to x and -2 : 3x-6
2. Next add 6 to both sides : 3x-6=21
3. that answer will be 27 so your left with : 3x=27
4. Divide both sides by 3 and x=9
Answer:-5600000
Step-by-step explanation:
Answer:
P = 4(2x + 5)
P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)
Step-by-step explanation:
Given that:
Perimeter of square = 4 * s
Where s = side length
If perimeter, P = 8x + 20
Then,
4s = 8x + 20
Divide both sides by 4
4s / 4 = (8x + 20) / 4
s = 2x + 5
P = 4s
P = 4(2x + 5)
Or
P = 2x + 5 in 4 places
P = (2x + 5)+(2x + 5)+(2x + 5)+(2x + 5)
