Can anybody help me with this question?

Answers

Answer 1

Answer: For number 16 we need to write the data as a ratio then convert to a unit rate (amount per 1)...

308/14 = x/1

Cross multiply

14x = 308
x = 308/14
x = 22

So the fuel efficiency is
22 miles per 1 gallon or

22/1

For number 17, since the car was driven at 48 mph, we just have to divide distance driven by speed to get how long it took...

288 miles ÷ 48 mph =

6 hours

Answers

it seems like you have the answer already. but heres how its calculated.
$(100)/(15) = (?)/(3)$
so the missing number is 20 **cross multiply 100 and 3 to get 300 then divide 15 into 300 to get 20**

$(160)/(100) = (80)/(?)$
so the missing number is 50
**cross multiply 100 and 80 to get 8000 then divide 160 into 8000 to get 50**

Answer:

x=4

y=3

Step-by-step explanation:

we have the following equations

3x+y=15 equation 1

5x-4y=8 equation 2

using equation 1 we have:

y=15-3x equation 3

using equation 3 in equation 2 we have:

5x-4(15-3x)=8

5x-4*15+4*3x =8

5x-60+12x = 8

17x=68

x=68/17

so we have x=4

finally in equation 3:

y = 15-3(4)

y = 15-12

y = 3

A) 50 I think it will always be 50%

Answer:

250

She spins the spinner 1 thousand times, there is only 1 blue tile so 25% of 100 would be 25 but since its 1000 just add a zero to 25 and you have 250
