Question

Solve each proportion:
4.) x/4=13/52
5.) x/2x+1=16/40
6.) 9/10=9x/70
7.) 2/7=b+1/56
8.) 11/y=9/27
9.) 3/34=m/51

PLEASE HELP I HAVE NO IDEA WHAT TO DO!!!! ):

Answer 1

well these take a little cross multiplying

in

4. x = (13*4)/52 multiply by the denominator of the left hand fraction.

5. 40x = 16(2x + 1)... or 40x = 32x + 16 cross multiply then solve for x

6. multiply by the denominator on the right (9*70)/10 = 9x then solve for x

hope this gives you the idea.

Answer 2

you have to put them in proportion

Answer 3

hold on lemme do them

Answer 4

Okay!(:

Answer 5

4. 1

Answer 6

what?

Answer 7

4. x=1

Answer 8

correct

Answer 9

all you really had to do is 4*13=x*52

Answer 10

5, 6, and 7 are super confusing to me

Answer 11

ok hold on

Answer 12

For 8. I got 33 and for 9. I got 4.5

Answer 13

6=x=7

Answer 14

I need to show work.

Answer 15

6. 9*70=630
divided by 10 =63
now you divide 63/9=7

do you understand?

Answer 16

yes

Answer 17

whats so funny @Luis_Rivera and @beautiful_ladie how did you do 8?

Answer 18

The answer was given correctly in the first solution, every single one, you just cross multiply.
1) 52*x=13*4, therefore x=1 and the ration is 1/4
2) 40*x=(2x+1)*16, therefore x=2, the ratio is 2/5
3) 9*70=9*x*10, therefore x=7, the ratio is 63/70
4) 2*56=(b+1)*7, therefore b=15, and the ratio is 16/56
5) 11*27=9*y, therefore y=33, and the ratio is 11/33
6) 3*51=34*m, therefore m=4.5 and the ratio is 4.5/51

Answer 19

crossed multiplied and got 9y=297, then divided by 9

Answer 20

correct @Khushal_Shah

Answer 21

@beautiful_ladie you got 8 and 9 right

Answer 22

How about 7?

Answer 23

it is 15 look at what @Khushal_Shah wrote

Answer 24

I only see up to 6
