Number 8 is 357 ft²(remember, to find area, you multiply the length times the width. Number 9 is $360. Sorry, I don't know how to do number 7 without adding. Could I be named brainliest please?

A certain pickup truck gets 20mpg in the city and 28 mpg on the highway. If the driver drives 270 mi on 11 gal of gas, determine

Snezhnost [94]

Answer:

95 city and 175 highway miles.

Step-by-step explanation:

The driver gets 20 mpg in city, and 28 mpg on the highway.

An equation that could be written is

20x+28y=270

This equation accounts for the distance traveled.

x+y=11

This equotion accounts for how many gallons were driven.

Multiply the bottom equation by 20, so you can solve the set of equations.

20x+28y=270

20x+20y=220

subtract them

8y=50

y=6.25

now plug this back into x+y=11

x+6.25=11

x=4.75

Now 4.75×20=95 city miles and 6.25×28=175 highway miles.

1. Un examen de Matemáticas ha sido aprobado por 6/9 de los estudiantes. Al resto de los estudiantes le toca repetir el examen.

Eddi Din [679]

Answer:

15 students

Step-by-step explanation:

The fraction of students who will repeat the exam is:

$1-\frac{6}{9}$

= $\frac{9}{9} -\frac{6}{9} =\frac{3}{9}$

simplified is:

$\frac{1}{3}$

Extract this fraction of 45:

$45(\frac{1}{3} )=\frac{45}{3} =15$

Hope this helps
