Answer:

**Answer:**

The car that has a fuel efficiency of 40 mpg consumed 35 gallons, while the car that has a fuel efficiency of 20 mpg consumed 40 gallons.

**Step-by-step explanation:**

The variable **a** will represent the fuel consumed by the first car, and the variable **b** will represent the fuel consumed by the second car.

Set up the formula: **a+b=75**, which will represent the total gas consumption.

The formula **20a+40b=2200** will help you solve.

To solve, we will first solve for **a **by changing the formula from **a+b=75** to **b=75-a**. Then you plug in the value of **b** to the second formula:

**20a+40(75-a)=2200**

**20a+3000-40a=2200**

**3000-20a=2200**

After subtracting 3000 from both sides, you are left with **-20a=-800**. Multiply both sides by **-1** so that both sides are positive:

**20a=800**

**a=40**

Now that we know that the car with a 20 mpg fuel efficiency consumed 40 gallons that week, we can subtract 40 from 75, leaving us with **35** being the amount of gallons consumed by the car with a 40 mpg efficiency.

consider the ratio of 153 per 108. write this ratio in different forms. a ratio written as a reduced fraction and as a decimal rounded to the hundredths.

Mary has a bag with 80 pieces of candy. She gives ¼ of her candy to John and 10% to Lisa. How much more candy did she give to John then Lisa?

Brian and Jennifer are planning to get married at the end of the year. They read that certain diets are healthier for specific blood types and hope that they both have the same blood type. Unfortunately, neither Brian nor Jennifer can remember their blood type.Suppose a recent study shows that 29% of adults have blood type A, 35% of adults have blood type B, 24% of adults have blood type AB, and 12% of adults have blood type O. The tree diagram shows the possible outcomes for Brian and Jennifer along with their associated probabilities. What is the probability that Brian and Jennifer share the same blood type?

The measure angle of 4?

Answer:

Angle 4=83

Angle 3=46

Explanation:

For angle 4- Angles in a triangle add to 180 degrees

46+51=97 180-97=83

For angle 3- angles on a straight line add to 180 degrees

51+83=134 180-134=46

I hope this helped :)

f(7)=

f(-2)=

f(-4)=

The **value **of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 **respectively**.

A certain kind of **relationship **called a function **binds **inputs to essentially one output.

A function can be regarded as a **computer**, which is helpful.

The machine will only accept **specified **inputs, described as the function's **domain**, and will potentially produce one output for each input.

In other words, the **function **is a **relationship **between variables, and the **nature **of the relationship defines the function for example y = sinx and y = x +6 like that.

Given,

f(x)=2x-3

f(7) so put x = 7

f(7) = 2(7) - 3

**f(7) = 11**

Now,

f(-2) so put x = -2

f(-2) = -2×7-3

**f(-2) = -17**

Now,

f(-4) so put x = -4

f(-4)= -4×7-3

**f(-4) = -31 **

Hence,The **value **of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 **respectively**.

#SPJ2

**Step-by-step explanation:**

f(x)=2x-3

now,

f(7)=2× 7-3

=14-3

=11

f(-2)='-2×7-3

= -14-3

b= -17

f(-4)= -4×7-3

= -28-3

= -31
