$\bf \cfrac{3}{4}x+\cfrac{5}{8}=4x\impliedby \textit{let's multiply both sides by }4\cdot 8=\boxed{32}
\\\\\\
32\cdot \cfrac{3}{4}x+32\cdot \cfrac{5}{8}=32\cdot 4x\implies 24x+20=128x$

and surely you know how much that is.

to get rid of the denominators, you can simply get their LCD and multiply both sides by it.

Twice c is greater than 28

OLEGan [10]

I think C would equal 15, because 14 + 14 = 28; 15 + 15 = 30 which is greater than 28.

I solved this answer already and I got 43, but I don’t know if it’s correct so

faltersainse [42]

Answer:

= 43

Step-by-step explanation:

Solve the brackets first

{7 × 8 - 7} -2 ×3

{56 - 7} -2 ×3

49 -2 ×3

49 -6

= 43

Courtney and Chelsea are leading a family hike on Saturday. The number of snacks Chelsea is bringing can be represented by 2x. C

Answer:

Courtney is bringing 8 snacks

Step-by-step explanation:

Chelsea's snacks are represented as 2x.

2x means 2 · (a number)

If Chelsea brought 16 snacks and the amount of snacks represented by 2x, we have to figure out what times 2 equals 16.

In order to find out, we have to divide.

16 ÷ 8 = 2

This means 2 · 8 = 16

Since the amount of snacks Courtney brings is represented as "x", she would have brought 8 snacks.

Hope this helped! :)
