Question

1 Whatis the value ofthe expression y 1/2 +z)+6 ( 2 + when y= 2 and 7 = 3 ? 4

Answer 1

Answer:

Option C

Step-by-step explanation:

Given:

$y = 2$

$z = \dfrac{3}{4}$

Substitute the values into the expression:

⇒ y(1/2 + z) + 6

⇒ 2(1/2 + 3/4) + 6

Make common denominators in the parenthesis:

⇒ 2(1/2 + 3/4) + 6

⇒ 2(2/4 + 3/4) + 6

Simplifying the expression:

⇒ 2(5/4) + 6

⇒ 2 × 5/4 + 6

**Keep in mind that multiplication first, then addtion

⇒ 10/4 + 6

Make common denominators:

⇒ 10/4 + 24/4

⇒ 34/4

Simplify the fraction:

⇒ 17/2 (Option C)

Answer 2

2(1/2+3/4)+6=

17/2 or 8.5

The answer is C
