Then, I would subtract the second row from the first row to make 7y=-70
Next, divide both sides by 7 to solve for y. y = -10.
2) To eliminate the y-terms, I would multiply the first equation by 2 and the second equation by -3. It will make 4x-6y=42 and 18x-6y=-21.
Now, subtract the two equations to make -14x=63.
Lastly, divide both sides of the equation by -14 to find x. x = -9/2
3) The answer as an ordered pair is (-9/2, -10).

Answer:
if ∠1 = 70°, then ∠5= 70°
Hence, option (A) is correct.
Step-by-step explanation:
Given
∠1 = 70°
To determine
We need to determine angle ∠5
From the diagram, it is clear that a transversal line crosses the two parallel lines, the angles in the matching corner would be corresponding angles.
We know that when two lines are parallel, their corresponding angles are equal.As angle ∠5 is the corresponding angle of angle ∠1 = 70°.
Also, the corresponding angles are equal here.Therefore,
if ∠1 = 70°, then ∠5= 70°
Hence, option (A) is correct.

Holly has $225 to spend at the shopping mall. She decides to buy sweaaters and pants with her money. Sweaters cost $45 each and pants cost $25 each. The equation 45s + 25p = 225 represents this situation.
If Holly buys 3 sweaters, what is the greatest number of pants she can buy?
Answers
Answer:
3 pairs of pants
Step-by-step explanation:
Plug 3 in for s. Your equation should now be 45(3) +25p=225
Then distribute 135+25p=225
Subtract 25p=90
Divide p=3.6
Since you cannot buy half of a pair of pants you need to round down to three

-8x +(-56)=16
Answers
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?
Answers
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.

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.
Answers
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%
