Devaughn is 8 years older than Sydney. The sum of their ages is 64. What is Sydney's age?

Zigmanuir [339]

Answer:

Sydney's age is 28

Step-by-step explanation:

Let Devaughn be D

And Sydney be S

D=S+8..... equation 1

D+S=64...... equation 2

Substitute equation 1 to equation 2

S+8+S=64

2S+8=64

2S=64-8

2S=56

S=56/2

S=28

Hope it helps

Good luck

The sum of 3 consecutive even integers is 576. Find the integers

alisha [4.7K]

You can write the equation
x+1+x+3+x+5=576
Combine like terms
3x+9=576
Subtract 9 from both sides
3x+9-9=576-9
3x=567
Divide both sides by 3
3x/3=567/3
x=189
The first integer is 190, the second is 192 and the third is 194 (enter it into the original equation to get those answers)

Paul's car holds at most 17 gallons of gas. Now it has 9 gallons. Explain how to find the amount of gas he needs in liters. Use

yulyashka [42]

Answer:

30.08 liters of gas.

Step-by-step explanation:

Given:

Paul's car holds at most 17 gallons of gas.

Now it has 9 gallons.

Question asked:

Explain how to find the amount of gas he needs in liters.

Solution:

Capacity of Paul's car = 17 gallons of gas.

Now it has = 9 gallons of gas.

He need more = 17 - 9 = 8 gallons of gas.

Now, we have to convert it into liters:-

As we know:

Given:

1 gallon = 4 quarts ( Unitary method )

8 gallons = $4\times8=32\ quarts$

Now, we will convert it into liters:- ( Unitary method )

1 quart = 0.94 liters

32 quart = $0.94\times32=30.08\ liters$

Thus, he needs 30.08 liters of gas.
