Question

One real-world problem that is solved by an equation
Kevin had $15 with him. His mother gave him $10 and his father also gave him some money. After this, he had a total of $37 with him. How much money did his father give him?

Answer 1

i just need the work not the answer

Answer 2

Okay, Kevin had $15 on him, right?

Answer 3

yesh

Answer 4

We will use a b and c
a=15, b= 10, and c= x

Answer 5

ok

Answer 6

We know Kevin has 15 and his mom gave him 10, so we have 15 + 10 + x =?

Answer 7

25

Answer 8

No.

Answer 9

BEcause it's 15 + 10, PLUS x

Answer 10

So for now it's undefined.

We know that the total is 37.

Answer 11

The equation is now 15 + 10 + x =37.

Answer 12

oh duh

Answer 13

So 15 + 10 =?

Answer 14

ok

Answer 15

x

Answer 16

No. x is the missing number

Remember, a= 15, b = 10, c= x

Answer 17

so is it c? idk im confused

Answer 18

No.
a is what Kevin has, b is what his mom gave him, and c is what his dad gave him.

Answer 19

We know a and b, but not c

Answer 20

We also know that if you add a b and c you get 37.

Answer 21

So you add a and b which is 15 + 25.

Answer 22

*15 + 10 rather.

Answer 23

So what is the result? of 15 + 10?

Answer 24

25

Answer 25

Okay, so we now have (15+10) + x = 37

Answer 26

Solve the equation in the parentheses and you get 25 + x =37

Answer 27

Now, it's as simple and 37 -25

Answer 28

12

Answer 29

We know the total is 37, and that Kevin has 25. meaning if you take 25 from 37, you take what he had and what his mom gave him, leaving only what his dad gave him.

Answer 30

So 15 + 10 + 12=?

Answer 31

Since we now know a= 15, b= 10, c=12

Answer 32

37

Answer 33

thank you so muc

Answer 34

No problem.
