Answer:
27 < 5*n +7
n<4
Step-by-step explanation:
Twenty-seven is smaller than five times a number increased by seven
Increase means add
27 < 5*n +7

27-7 <5n+7-7
20 < 5n
Divide by 5
20/5 < 5n/5
4 <n
Answer:
x = 28
Step-by-step explanation:
12/8 = (x-7)/14
Cross multiply.
8(x-7) = 12 × 14
Expand and multiply.
8x - 56 = 168
Add 56 on both sides.
8x = 168 + 56
8x = 224
Divide 8 into both sides.
x = 224/8
x = 28
