What is the value of 6(2b-4) when b =5
Sindrei [870]

Answer: The value of 6(2b-4) is 36.


Step-by-step explanation:

Given expression: 6(2b-4)

To find the value of 6(2b-4) at b= 5, we need to substitute the b=5 in the expression, we get

6(2(5)-4)\\=6(10-4).......[\text{solve parentheses}]\\=6(6)\\=6\times6=36

\\\Rightarrow6(2(5)-4)=36

Therefore, the value of  6(2b-4) is 36, when b=5.

17X+1 +20x-14 = 90<br> find x
professor190 [17]

Answer:

x = 2.8

Step-by-step explanation:

17x+1+20x-14 = 90

Combine like terms.

37x-13 = 90

Add 13 on both sides.

37x-13 = 90

     <u>+13   +13</u>

37x = 103

Divide both sides by 37.

37x = 103

<u>/37     /37</u>

x = 2.8

(I rounded up, but if you need a more specific number, just search up 103 divided by 37.)

Hopefully this helps you!! Have an amazing day c:
