A family has two cars. The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of

cestrela7 [59]

The amount of gas consumed by first and second car were 20 gallons and 15 gallons respectively.

Explanation

Suppose, $x$ gallons of gas were consumed by the first car.

As the total gas consumption in one week is 35 gallons, so the amount of gas consumed by second car will be: $(35-x)$ gallons.

The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of 15 miles per gallon of gas.

So, the distance traveled by the first car in $x$ gallons of gas $=35x$ miles and the distance traveled by the second car in $(35-x)$ gallons of gas $=15(35-x)$ miles.

Given that, the two cars went a combined total of 925 miles. So, the equation will be.....

$35x+15(35-x)=925\\ \\ 35x+525-15x=925\\ \\ 20x=925-525=400\\ \\ x=\frac{400}{20}=20$

So, the amount of gas consumed by the first car is 20 gallons and the amount of gas consumed by the second car is: (35 - 20) = 15 gallons.

$4^{3}+2(8)=80$

Solution:

Given expression:

$4^{3}+2(8)$

Expansion of PEDMAS:

Parenthesis, Exponents, Division, Multiplication, Addition, Subtraction.

To solve the given expression using pedmas rule.

First solve the expression with parenthesis.

$4^{3}+2(8)=4^{3}+16$

Next do the exponents.

$4^{3}+2(8)=64+16$

Finally do the addition.

$4^{3}+2(8)=80$

Hence the answer is 80.

Hannah is 2 times her sister’s age. The sum of their ages is no more than 18 years. 1) Write an inequality that can be used to r

svetoff [14.1K]

Answer:

1) $x+2x\leq 18$ .

2) $6$ years

Step-by-step explanation:

Let Hanna's sister be $x$ years old.

Then Hanna will be $2x$ years old.

The sum of their ages will be $x+2x$ years.

The statement "no more than 18" means the sum of their ages is less than or equal to 18.

The required inequality is;

$x+2x\leq 18$ .

The inequality we just found is

$x+2x\leq18$ .

We simplify to get;

$3x\leq 18$ .

we divide both sides by $3$ to get;

$x\leq 6$ .

Therefore the oldest age Hannah's sister can be is $6$ years
