Answer:
x = 4/7
Step-by-step explanation:
5/3 x = 20/21
Multiply by 3/5 on each side to isolate x
3/5 *5/3 x = 20/21 * 3/5
x = 20/21 * 3/5
Rewriting the right hand side
x = 20/5 * 3/21
x =4 * 1/7
x = 4/7
Remember that the formula for the difference of squares is 
, where 
and 
are expressions or values.
In this case, we have two expressions, 
and 
. We are also given that their difference of squares is 4444. Using the formula, we can say:
Now, we can solve for :
We now know that the first number is 1110. To find the second number, we must add 2 to the first number, which means that the second number, represented by , is equal to 1112.
Our two numbers are 1110 and 1112.
Answer:
$500 + 0.02x = $200 + 0.05x
Step-by-step explanation:
Jessica's first option: J1 = $500 plus sales commission of 2%:
J1 = $500 + 0.02x, where x: weekly sales amount
Her second option: J2 = $200 + 0.05x
Equating these two expressions, we get:
$500 + 0.02x = $200 + 0.05x
... which is the same as the third answer choice.
1.40 x 21 passes = 29.40 for passes.
38.40 - 29.40 = 9.00
