Alina is 6 years older than Greg. Amy’s age is 2.5 times Alina's age. Amy is 40. How old is Greg?

A. 16
B.10
C. 15
D.10

Answers

Answer 1

Answer:

Hi friend! The answer is D. 10

I hope this helps!

Answer 2

Answer:

B) 10

Step-by-step explanation:

Assign variables to each person:

A=Alina's Age

M=Amy's Age

G=Greg's Age

Set up a system of equations given the information:

A=6+G

M=2.5A

M=40

Notice that M is already given, so we can plug that into the second equation:

40=2.5A

16=A

So Alina is 16 years old, but the problem asks for Greg's age, so we plug Alina's age in the first equation:

16=6+G

10=G

So Greg is 10 years old, therefore B is the correct answer.

Annalise ended the week with $0. What number could you add to
$55.32 that would result in a sum of $0?

Answers

Answer:

-55.32

Step-by-step explanation:

55.32 + (-55.32) = 0

I hope this helps!

Answer:

Well the number would have to be a negative number, because, no positive number can cause a smaller number adding a positive number will always cause a larger number.

So the answer is: $55.32+(-$55.32)

Adding the -55.32 causes it to even out meaning that u basically just added the debt of 55.32. This debt is causing an decrease in the amount of money she has. So really you are subtracting money

for solve |2x-2|=6 for x
X=



Answers

Answer:

x  =  6 ,  − 6

Step-by-step explanation:

Answer:

x = 4x = -2

Step-by-step explanation:

Solving for x

|2x-2|=6

1. 2x - 2 ≥ 0 ⇒ 2x ≥ 2 ⇒ x ≥ 1

2x - 2 = 62x = 8x = 4

2. 2x - 2 < 0 ⇒ 2x < 2 ⇒ x < 1

2x - 2 = -62x = -4x = -2

What is 1/5 as a percentage and decimal?

Answers

Answer:

1/5 as a percentage:

1/5*100

1/1*20

20/1

20%

1/5 as decimal:

(JUST SIMPLY DIVIDE 1/5)

0.2

Answer:

20% and 0.20

Step-by-step explanation:

Let's say 5/5 = 100, so then in order to convert 1/5 into a percentage, all you have to do is divide 100 by 5, and that will be your percentage:

100 / 5 = 20

So, 1/5 = 20%

Now, as a decimal its basically the same thing, but instead of thinking of it as 100, you think of it as 1.00, and then your decimal form of 1/5 will be 0.20

Josh wants to determine the number of loaves of bread he can bake using the 13 and one-third cups of flour he has. If each loaf requires 3 and four-fifths cups of flour, how many loaves can Josh bake? 3 loaves of bread 4 loaves of bread 50 loaves of bread 51 loaves of bread

Answers

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

The number of loaves Josh can bake with 13 and one-third cups of flour is 4 loaves.

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

Josh wants to determine the number of loaves of bread he can bake using the 13 and one-third cups of flour he has.

13(1/3) can be written as,

= 13(1/3)

= 40/3

Each loaf requires 3 and four-fifths cups of flour.

This can be written as,

3(4/5) cups of flour = 1 loaf

19/5 cups of flour = 1 loaf

Multiply 5/19 on both sides.

1 cup of flour = 5/19 loaf

Multiply 40/3 on both sides.

40/3 cups of flour = 40/3 x 5/19 loaf

40/3 cups of flour = 3.5 loaf

This means we can make 4 loaves.

Thus,

The number of loaves Josh can bake with 13 and one-third cups of flour is 4 loaves.

What is 3 y + 5 x = negative 15 written in slope-intercept form?

Answers

Answer:

The answer would be y=-5/3x-5!

Step-by-step explanation:

You want to make the equation to y=mx+b, so you have to make y by its self. Subtract 5x from both sides and you'll get 3y=-5x-15. Now divide 3 by both sides and you'll get y=-5/3x-5 which would be the answer!

Answer:

y=(-5/3)x-5

Step-by-step explanation:

so the slope intersect form is y=mx+b

3y+5x=-15

subtract 5x from both sides

3y= -5x-15

divide both sides by 3

y= (-5/3)x - 5
