The cost of the dryer will be $450
In the given sum the combined cost of the washer and dryer is $813
let the cost of the dyer be x
the cost of the washer will be (87 - x) as it is mentioned in the question washer costs $87 less than the dryer
According to the problem :
∴ x + (x-87) = 813
=> x+x-87 = 813
=> 2x - 87 = 813
=> 2x = 813 +87
=> 2x = 900
=> x = 900/2
=> x = 450
So the cost of the dryer is $450
The cost of the washer is = x - 87 = 450 - 87 = $363

24= 8 + 2 (y - 10)
step by step pls
Answer:
18
Step-by-step explanation:
Distribute the 2 to the terms inside the parenthesis.
24=8+2y-20
Combine like terms
24=2y-12
Add 12 to 24
36=2y
Divide by 2
18=y
Answer:
18
Step-by-step explanation:
24 = 8 + 2 (y-10)
24-8 = 8 + 2 (y-10) -8
16 = 2 (y-10)
16 = 2y - 20
16 + 20 = 2y -20 + 20
36 = 2y
36/2 = 2y/2
18 = y
Which expression has the same value as -73 +3/?
The expression come -70
given;
In mathematics, multiplication can be represented by using the symbol × or the symbol ·. Moreover, multiplication can be also represented just by leaving the numbers or values side by side without any symbol. For example, the expression 5x + y implies 5 should be multiplied by x.

Melissa is simplifying an expression using the order of operations. She adds 3 and 4, squares the result, and subtracts 9. Which expression is Melissa simplifying? (3+4-9)², 3+4²-9, 3²+4²-9, (3+4)² - 9
we get that Melissa is trying to solve the expression ( 3 + 4) ² - 9.
We are given that:
Melissa is simplifying an expression using the order of operations which can be addition, subtraction, multiplication or division.
She adds 3 and 4, squares the result, and subtracts 9.
We will first add 3 and 4:
3 + 4
Now we will square them:
( 3 + 4) ²
Now, we will subtract 9 from it:
( 3 + 4) ² - 9
So, the expression becomes:
( 3 + 4) ² - 9
Therefore, we get that Melissa is trying to solve the expression ( 3 + 4) ² - 9.

ASAP HELP PLEASE!!!!
Answer:
x^21/5
Step-by-step explanation:
To change this expression to an expression with a rational exponent, we need to change the radical to a rational (fractional) exponent. Just as square root is a one half power and cuberoot is a one-third power, a fifth root is a one-fifth power.
Once the radical is changed to a fraction, we will just use the exponent rule that says when you raise a power to a power, you multiply exponents.
