I need help finding 13-22

1 answer:

4 0

13. (3/8)*q + 12 = 36
3q/8 = 24
3q = 192
q = 64

14. 3 - (3/4)n = 9
-3n/4 = 6
-3n = 24
n = -8

15. (7/9)v + 2 = 23
7v/9 = 21
7v = 189
v = 27

16. 7 + (1/8)l = -2
l/8 = -9
l = -72

17. (v/-3) + 8 = 22
v/-3 = 14
v = -42

18. 8x - 16 + 8x = 16
16x = 32
x = 2

19. 12a - 14a = 8
-2a = 8
a = -4

20. 7c - 8 - 2c = 17
5c = 25
c = 5

21. 6 = -y + 42 - 2y
-36 = -3y
y = 12

22. 16 + 8r - 4r + 4 = 24
20 + 4r = 24
4r = 4
r = 1

Last year Billy weighed 75kg. This year he weighed 90kg. With what percentage did his weight increase. SHOW ALL WORK!!!

polet [3.4K]

well let's round. 90= 100, 75=80 that is how I face it. now 80 is 1/5 of 5/5= 100. so as a (%) we would sort it like:::: it is 80% out of +100 so he must have grown around 13%-16% due to him being 75kg in the past.

Subtract x2 from x1 to get -7. After that subtract y2 from y1 to receive 3. That leaves you with -7/3 which simplified is -2.1333*

Solve the question: 3(.5y-6)=12

makvit [3.9K]

Answer:

y = 20.

Step-by-step explanation:

Distribute:

$3(0.5y)-3(6)=12$

$1.5y-18=12$

Add 18 to both sides:

$1.5y-18+18=12+18$

$1.5y=30$

Solve for y:

$\frac{1.5y}{1.5}=\frac{30}{1.5}$

$y=20$
