Step-by-step explanation:

Given

1. 6.4+2.7+1.6+53

2. 4/3×7×3×10

Required

Evaluate

Solving (1):

Using Cumulative Property of Addition; We have

Solving (2):

Using Cumulative Property of Multiplication; We have

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

answer: 48
