Answer:
80%
Step-by-step explanation:
Since (78-23) is in the bracket, you need to perform the operation of minus first.
that get you with
-56x(55)÷4
and then you just do it step by step
-56x55 = -3080
-3080÷4 = -770
Answer:
The answer to your question is L = 10 in , M = 9 in ; S = 5 in
Step-by-step explanation:
Data
longest side = 5 + x in
medium side = 4 + x in
shortest side = x
Perimeter = 24 in
Process
1.- Write and equation to solve this problem
Perimeter = longest side + medium side + shortest side
Substitution
24 = (5 + x) + (4 + x) + x
Simplification
24 = 5 + x + 4 + x + x
24 = 9 + 3x
24 - 9 = 3x
15 = 3x
x = 15/3
x = 5
2.- Calculate the lengths of the side
Longest side = 5 + 5 = 10 in
Medium side = 5 + 4 = 9 in
Shortest side = 5 in
Answer:
21x-28
Step-by-step explanation:
When 7 is distributed across this equation, you get 21x and 28
