5(n - 2) = n + 7
5n - 10 = n + 7
5n - n = 7 + 10
4n = 17
n = 17/4 or 4 1/4 <== ur answer
check..
5(n-2) = n + 7
5(17/4 - 2) = 17/4 + 7
5(17/4 - 8/4) = 17/4 + 28/4
5(9/4) = 45/4
45/4 = 45/4 (correct)
Answer:
TX=8, all sides of an equilateral triangle are congruent
Your answer would be 4% because if you subtract 8 from 12 you'd get 4.
Answer:
y=3x-12
Step-by-step explanation:
We need to find the m of y = mx+b which is the slope:
-3-(-6)/3-2 = 3 as our slope
We know have y = 3x+b.
If we keep applying slope to the point (2,-6) and go downwards. We hit (0,-12). That's our y intercept. So we replace b with our y intercept which is -12. We know get y = 3x-12
Answer:
Hey the answer is 20%.
Step-by-step explanation:
You multiply the $90 with 20%,
but in order to figure that out you need to:
Calculate the savings: 20% of $90 = $18.
Subtract the savings from the original price to get the sale price: $90 - $18 = $72. You're all set!
