Consider the following formula:

[tex]\[ A = B + 3(4 - C) \][/tex]

If [tex]\( B = 5 \)[/tex] and [tex]\( C = 2 \)[/tex], what is the value of [tex]\( A \)[/tex]?

A. 7
B. 11
C. 12
D. 17

Sagot :

Let's solve the problem step-by-step using the given values [tex]\( B = 5 \)[/tex] and [tex]\( C = 2 \)[/tex].

The formula we are given is:

[tex]\[ A = B + 3(4 - C) \][/tex]

Step 1: Substitute [tex]\( B = 5 \)[/tex] and [tex]\( C = 2 \)[/tex] into the formula.

[tex]\[ A = 5 + 3(4 - 2) \][/tex]

Step 2: Simplify the expression inside the parentheses ([tex]\( 4 - 2 \)[/tex]).

[tex]\[ A = 5 + 3(2) \][/tex]

Step 3: Multiply 3 by 2.

[tex]\[ A = 5 + 6 \][/tex]

Step 4: Add 5 and 6 together.

[tex]\[ A = 11 \][/tex]

So, the value of [tex]\( A \)[/tex] is 11, which corresponds to option B.

Therefore, the correct answer is [tex]\( \boxed{11} \)[/tex].
