There are 5 pieces of chewed gum in each tube. So, if b = 5, how many pieces are there total?

Neporo4naja [7]

Answer:

There are 25 pieces of gum in total.

Step-by-step explanation:

If with b you refer at the amount of tubes, then you have 5 pieces of chewed gum for each tube and 5 tubes in total. Thus, you have to multiply your total of 5 tubes for 5, the amount of pieces of chewed gum, and you obtain that there are 5*5 = 25 pieces of chewed gum in total.

I hope this helped you!

What is the value of x in the equation ?

Eduardwww [97]

Answer:

Part A: x = -24

Part B: n = 2

Step-by-step explanation:

Part A:

The algebraic expression for: "StartFraction 2 Over 3 EndFraction left-parenthesis StartFraction one-half EndFraction. x plus 12 right-parenthesis equals left-parenthesis StartFraction one-half EndFraction left-parenthesis StartFraction one-third EndFraction x plus 14 right-parenthesis minus 3" will be ⇒ $\frac{2}{3} (\frac{1}{2} x+12)=(\frac{1}{2} (\frac{1}{3} x+14)-3)$

Multiply both sides by 6

∴ $6 * \frac{2}{3} (\frac{1}{2} x+12)=6*(\frac{1}{2} (\frac{1}{3} x+14)-3)$

∴ $4*(\frac{1}{2} x+12)=3 (\frac{1}{3} x+14)-18$

∴ 2x + 4*12 = x + 3 *14 - 18

∴ 2x - x = 3 * 14 - 18 - 4 * 12 = -24

∴ x = -24

============================================================

Part B:

The algebric expression for: "StartFraction one-half EndFraction left-parenthesis n minus 4 right-parenthesis minus 3 equals 3 minus left-parenthesis 2 n plus 3 right-parenthesis" will be ⇒ $\frac{1}{2}(n-4)-3=3-(2n+3)$
