1..) 2x +15 = 35 

Mathematics
1 answer:
Masja [62]3 years ago
3 0

Answer:

1) x=10

2) x=3

Step-by-step explanation:

1)

2x+15=35

Subtract 15 from both sides

2x=20

Divide both sides by 2

x=10

2(10)+15=35

20+15=35

35=35

this shows that 10 is the right answer

2)

7x-3=18

Add 3 to both sides

7x=21

Divide both sides by 7

x=3

7(3)-3=18

21-3=18

18=18

this shows that 3 is the right answer

Hope this helps

What is the length of one side of 400 sq in
RSB [31]

This is a square, and so all the sides will be the same measurements. Note that you are given an area, so you'll have to root the total area to get a side.

√400 = 20

One side's measurements is 20 in

hope this helps
