If a car can travel 250 miles on 10 gallons of fuel , how many gallons are requiered to travel 1325 miles
kupik [55]

Answer:

53 gallons of fuel

Step-by-step explanation:

Step 1: Set up a fraction given the data (Let "x" represent the distance in miles.)

\frac{10}{250} = \frac{x}{1325}

Step 2: Divide the given values (The given values are 10 over 250. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 0.04 once divided)

\frac{10}{250}\\\\10 \div 250\\\\=  0.04

Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the <em>opposite operation </em>in order to find the answer.)

1325 \times 0.04\\\\= 53

Therefore, 53 is the amount of gallons of fuel needed.

Evaluate each expression if w=2, x=3, y=5, and z=6. 3+4z
SashulF [63]

Answer:

27

Step-by-step explanation:

The expression is 3 + 4z

First, you must know what the value of the variable "z" is.

Because the problem already tells you that z = 6, all you have to do is substitute z with 4:

3 + 4z = 3 + 4(6)

Next, solve using the Order of Operations (P.E.M.D.A.S.).

According to the Order of Operations, multiplication (M) comes before Addition (A). That means you must multiply 4 by 6 first then add the product to 3:

3 + 4(6) = 3 + 24 = <u>27</u>
