Ilya [14]

Answer:

UV=142

Step-by-step explanation:

21x-13=10x+31

+13 +13

21x=10x+44

-10x=-10x

11x=44

÷11 ÷11

x=4

now substitute 4 in place of x (only have to solve one)

21(4)-13= 71

now multiply your answer by 2

<u>Ratio = Number of event 1 : Number of event 2</u> (in same unit, if necessary)

<u>10</u>

Girls preferring orange juice : Boys preferring orange juice

50 : 48 (Divide by 2 on both sides)

25 : 24

Boys preferring orange juice : Boys preferring grapefruit juice

48 : 10 (Divide by 2 on both sides)

24 : 5

Remember :

  • <u>1 week = 7 days</u>
  • <u>1 hour = 60 minutes</u>

<u />

<u>12</u>

3 minutes : 25 seconds

3 × 60 : 25 (Divide by 5 on both sides)

3 × 12 : 5

36 : 5

<u>13</u>

2 weeks : 6 days

2 × 7 : 6 (Divide by 2 on both sides)

7 : 3

<h3>You have the correct answer</h3><h3>Interest rate = 21.5%</h3>

===============================================

Work Shown:

i = P*r*t .... simple interest formula

i = simple interest

i = 2075-1000 = 1075

P = 1000 = amount borrowed (principal)

r = unknown interest rate

t = 5 = time in years

So,

i = P*r*t

1075 = 1000*r*5

1075 = 5000r

5000r = 1075

r = 1075/5000

r = 0.215

r = 21.5%

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalen
Alisiya [41]
The answer is <span>2(–4y + 13) – 3y = –29

Step 1: Express </span><span>x from the second equation
Step 2: Substitute x into the first equation:

The system of equations is:
</span><span>2x – 3y = –29 
x + 4y = 13

Step 1: 
</span>The second equation is:    x + 4y = 13
Rearrange it to get x:         x = - 4y + 13

Step 2:
The first equation is:          2x – 3y = –29 
The second equation is:    x = - 4y + 13
Substitute x from the second equation into the first one:
2(-4y + 13) - 3y = -29

Therefore, the second choice is correct.
