-2 multiplied by 3x = -6x
-2 multiplied by 7 = -14
so -6x-14=32-4x
move -6x to the other side
= -14= 32-4x+6x
simplify
=-14=32+2x
move 32 to the other side
= -14-32=2x
simplify
=-46=2x
divide
-46/2 = 2x/2
x = -23

If a=12 and 120% of a is equal to 80% of b then what is a+b
mojhsa [17]
A=12
120% of a =80% of b
120%a = 80%b
120a/100 = 80b/100
Divide through by 100
120a = 80b
Divide through by 80
120a/80 = b
But a=12
120x 12/80 = b
18 = b
b = 18

a+b = 12 + 18 = 30

Linda read 1/5 of a book on Friday and 2/7 of the book on Saturday. On Sunday she read 5/9 of the remaining pages. What fraction
insens350 [35]
Here, you just want to solve it by finding a common denominator.
1/5+2/7, because she read 1/5 and 2/7 of the book on separate days. The common denominator is 35.
7/35+10/35
=17/35
So that's how much of the book she read before Saturday.
Now it says that on Sunday she read 5/9 of the remaining pages, meaning:
1-17/35 should give us our answer
35/35-17/35=18/35
But since it says she read 5/9 of the remaining pages, we need to multiply 18/35 by 5/9 to get what 5/9ths of 18/35 is.
(18/35)(5/9)=2/7
Therefore she read 2/7ths of the book on Sunday.

What is 5x+8y=14<br> 4x=24
Flauer [41]

Answer:

x = 6, y = -2

Step-by-step explanation:

24/4 = 6

x = 6

8y = -16

y = -16/8

y = -2

Check: 5x6+8x-2= 14
