The product of 8/9 and the sum of a number and – 4 is less than or equal to 64.
Fiesta28 [93]

Answer:

x\leq 76

Step-by-step explanation:

Let x = unknown number

\implies \dfrac89 \times (x-4)\leq 64

\implies \dfrac{8(x-4)}{9}\leq 64

Multiply both sides by 9:

\implies 8(x-4)\leq 576

Expand brackets:

\implies 8x-32\leq 576

Add 32 to both sides:

\implies 8x\leq 608

Divide both sides by 8:

\implies x\leq 76
