Answer:

A and E

Step-by-step explanation:

(3*2)/(7*2)=6/14

(3*10)/(7*10)= 30/70

Answer:

1- 14

2- 24

3- 56

Step-by-step explanation:

its multiplied by 2 each time

Answer: 14, 24, 49

You just do as the attern tells you

Answer:

x/3.5h = -$1.4

So, x = -$1.4 * 3.5h

= -$4.9

Step-by-step explanation:

Since your losing $1.4 every hour, the 1.4 is supposed to negative.

Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours

and get  -$4.9.

Answer: No, the graph does not show a proportional relationship.

Step-by-step explanation:

Proportional relationships have to start at zero, and have a straight line.

Even though the graph has a straight line, it does not start at zero and therefore is not proportional.

(there is a formula)

Answer:

1. 6/15, or 2/5.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

2.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

Answer:

b=-25

Step-by-step explanation:

10= -2/5b

10=      -2/5b

------    -------

-2/5       -2/5b

b=-25

Check:

-2/5(-25)=10

10=10

Answer:

b=-25

Step-by-step explanation:

Answer: b = 90

Step-by-step explanation:

Full triangle is 180

5 + 4 = 9 + 1 (the smallest angle)

180 ÷ 10 = 18

First and smallest angle is 18

p= 18

Second angle is 72

18 × 4 = 72

Thrid angle is 90

18 × 5 = 90

b = 90

18 + 72 = 90 + 90 = 180

Answer:

7

Step-by-step explanation:

The coefficient is the number used to multiply a variable.

Hey there!

In order for us to find out which one is equivalent to 5 – 2m , we can go through all of your options to see which one gives us that!

“Equivalent to 5 – 2m”

Option A.

7 – 2(m + 1)

Distribute

7 – 2(m) + 2(1)

7 – 2m + 2

COMBINE LIKE TERMS

7 – 2 = 5

Option Answer: 5 – 2m

Option A can be a possible ANSWER ✅

Option B.

7 - (2m - 5)

DISTRIBUTE

7 – 2m + 5

COMBINE LIKE TERMS

7 + 5 = 12

–2m = –2m

Option Answer: –2m + 12

Option B CAN’T possibly be your ANSWER ❌

Option C.

7 - 2(m - 2)

DISTRIBUTE

7 - 2(m) + (–2)(–2)

7 – 2m + 4

COMBINE YOUR LIKE TERMS

7 + 4 = 11

–2m = –2m

Option answer: –2m + 11

Option C. CANT possibly be your ANSWER ❌
