Answer:

700 pages

Step-by-step explanation:

I first found out how many pages were in 1% so I divided 28 by 4.

I got 7 so I multiplied it by 100 and 700 was the answer.

Basically:

28÷4 = 7

7 x 100 = 700

I hope that kinda made sense!

Answer:

1.a+4=11

a=7

2.6=g+8

g=2

4.k+8=3

k=-5

5.j+0=9

j=9

6.12+y=15

y=3

7.h-4=0

h=4

8.m-7=1

m=8

9.w+5=4

w=-2

10.b-28=33

b=61

11.45+f=48

f=3

12.n+7.1=8.6

n=1.5

Hope This Helps!!!

What does x equal in y=|x| when y=-3

Simora [160]

Replace all the variables that we know the value for.

-3 = |x|

Make to equations from this one.

-3 = x and -3 = -(x)

Solve the first one.

-3 = x
x = -3 <-- Switch it around

-3 = -(x)
-(x) = -3 <-- Switch it around
x = 3 <-- Divide both sides by -1

So, there are two possible answers, -3 and 3.

Solve the following inequality for mm. Write your answer in the simplest form.<br> 10m − 3 > 6m+1

Georgia [21]

Answer:

m > 1

Step-by-step explanation:

Given: 10m − 3 > 6m+1

Add 3 to both sides: 10m > 6m + 4

Subtract 6m from both sides: 4m > + 4

Divide both sides by 4: m > 1
