kolezko [41]

Answer:

(3,-4)

Step-by-step explanation:

3x-7(2x-10)=37

3x-14x+70=37

-11x+70=37

-70 -70

-11x= -33

divide -11 both sides

x= 3

y=2(3)-10

y=6-10

y= -4

Describe a real-life multiplication situation for which an estimate makes sense . Explain why it makes sense

monitta

Answer: Here we have a real life multiplication situation for which an estimate make sense:-

Miley has 212 fiction books. Sharon has 3 times fiction books has many as Miley has, how many fiction books Sharon has

Solution :- Number of fiction books Miley has = 212

Number of fiction books Sharon has= 3 times 212

We know that 212 is near to 200 , so round off 212 to 200 (to the nearest hundred)

Thus the product becomes $3\times200=600$

Therefore, the estimated number of fiction books Sharon has=600

The ratio of the number of adults to the number of children at the resturant is 3:7. Identify the choices below that represent a

klasskru [66]

Answer: A: 6:14

C: 15:35

E: 30:70

Step-by-step explanation:

From the question, we are given that the ratio of the number of adults to the number of children at the resturant is 3:7.

The choices below that represent an equivalent ratio goes thus:

A: 6:14

This can be represented as: 6/14. The common factor is 2 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

B: 8:12

This can be represented as: 8/12. The common factor is 4 and we reduce to lowest term which would be: = 2/3 = 2:3

This is not an equivalent ratio.

C: 15:35

This can be represented as: 15/35. The common factor is 5 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

D: 21:9

This can be represented as: 21/9. The common factor is 3 and we reduce to lowest term which would be: = 7/3 = 7:3

This is not an equivalent ratio.

E: 30:70

This can be represented as: 30/70. The common factor is 10 and we reduce to lowest term which would be: = 3/7 = 3:7

This is an equivalent ratio.

The correct options are A, C,and E.
