-8x +(-56)=16
Answer:
x = -9
-8x + -56 = 16
-8x - 56 = 16
-8x = 16 + 56
-8x = 72
x = 72/8
x= -9
Answer:
-9
Step-by-step explanation:
-8x + (-56) = 16
Take away -56 from both sides
-8x = 72
Divide both sides by -8
x = -9
a copy machine can copy a report in 30 min. when a second copy machine is used at the same time, the copying can be done in 18 min. how long would it take the second copy machine to do the copying alone?
Answer:
Step-by-step explanation:
A copy machine can copy a report in 30 mins. When a second copy machine is used at the same time, the copying can be sone in 18 min. How long would it take the second copu machine to do the copying alone?
i have:
x=30
x+y=18
that would be -12..not right?
The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.
Calculation of the time taken:Let we assume x be the time required at the time when using both machines.
Let us assume the completed job = 1
we know that
copy machine 1 will do [tex]x/30[/tex] of the job
and
copy machine 2 will do [tex]x/18[/tex] of the job
So, it can be like
[tex]\frac{x}{30} + \frac{x}{18} = 1[/tex]
So,
18x + 30x = 540
48x = 540
x = 11.25 minutes
hence, The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.

Simplify the expression.
5.3x - 9 + 7.6x
Answer:
12.9x-9
Step-by-step explanation:
First you have to combine the like terms which are 5.3x + 7.6x= 12.9x. Then you just rewrite the equation 12.9x-9. You just leave the 9 by it self beacuse thers no other like terms.
Anwer
12.9x−9 :)
5.3x+−9+7.6x
Combine Like Terms:

=(5.3x+7.6x)+(−9)
=12.9x+−
Find m∠A in ABC if m∠B = 38° and m∠C = 38°
Answer:
∠A = 104
Step-by-step explanation:
Triangles are equal to 180° so if one angle is 38° and the other angel is equal to 38°, then the third angle must make each of those angles add up to 180.
If you add 38 + 38 and subtract the sum from 180 you will get the measurement of angle A
(38 + 38) - 180 = 104

An employee earns a gross pay of $1,200.00 per week. The employee's net pay is $850.00. The employee's voluntary 401(k) contribution is $50.00 per month.
Answer:
$300 was deducted from tax. The tax rate is 26.1%
Step-by-step explanation:
An employee earns a gross pay of $1,200.00 per week. The employee’s net pay is $850.00. The employee’s voluntary 401(k) contribution is $50.00 per month.
There was blank deducted for taxes. The tax rate is blank
Solution:
Contributions that are made for retirement such as 401(k) contribution plans are made on a pretax basis. This means that they are removed from your taxable income, thereby reducing the tax.
Gross pay = $1200
Taxable income = Gross pay - 401(k) contribution
Taxable income = $1200 - $50 = $1150
Net pay = $850
Tax = Taxable income - Net pay
Tax = $1150 - $850
Tax = $300
Tax rate = (Tax / taxable income) * 100%
Tax rate = ($300 / $1150) * 100% = 26.1%

Kim saved $250 to buy new clothes for her summer vacation. She found several items she would like to buy, but is trying to decide if she has enough money to buy all the items she likes. She found a bathing suit for $35, two pairs of shoes for $15 each and five shirts with an average cost of $17 per shirt. She will have to pay 6% sales tax. If she buys all of the items, how much sales tax will she have to pay?
Answer:
She will have to pay $9 as sales tax
Step-by-step explanation:
Total amount with Kim = $250
Bathing suit = $35
Two pairs of shoes = 2 × $15
= $30
Five shirts = 5 × $17
= $85
Cost of items = Bathing suit + Two pairs of shoes + Five shirts
= $35 + $30 + $85
= $150
Sales tax = 6%
Amount of sales tax paid = 6% of $150
= 6/100 × 150
= 0.06 × 150
= $9
Kim will have to pay $9 as sales tax
Total cost of the items = cost of items + sales tax
= $150 + $9
= $159
Kim has enough money to buy all the items she likes

What number would you multiply the 2nd equation by in order to eliminate the y terms?
4x - 4y = 16
2x + y = 5
Answer:
x=3
y=-1
Step-by-step explanation:
first multiply the 2nd row by 2 so you will get
4x-4y=16
4x+2y=10
then subtract the 2nd row from the first row and so you will get
-6y=6
then solve for y in the above equation
y=-1
then substitute y=-1 into any 2 equations .
i picked the first 1
4x-4 × -1=16
then solve for x .
you will get
x=3
Use the order of operations to evaluate this expression: 7 + (5 – 9)2 + 3(16 ÷ 8).
Answer:
= 7 + (5 – 9)2 + 3(16 ÷ 8)
= 7 + (-4)2 + 3(2)
= 7 + (-8) + 6
= -1 + 6
= 5
Step-by-step explanation:
Remember to use PEMDAS when solving.
