Answer:
x=-1, y=-5
Step-by-step explanation:
y=3x-2 (1)
x-y=4 (2)
sub (1) into (2)
x-(3x-2)=4
x-3x+2=4
-2x=2
x=-1
sub x=-1 into (1)
y=3(-1)-2
=-3-2
y = -5
Therefore: x=-1, y=-5 :))
Answer:
x = -1, y = -5
Step-by-step explanation:
y = 3x - 2
x - y = 4
x - y = 4
x - (3x - 2) = 4
x - 3x + 2 = 4
-2x + 2 = 4
-2x = 2
x = -1
x - y = 4
-1 - y = 4
-y = 5
y = -5
Check:
x - y = 4
-1 - (-5) = 4
-1 + 5 = 4
4 = 4
Decide whether or not each equation represents a proportional relationship. A.The remaining length (L) of 120-inch rope after x inches have been cut off: 120−x=L b.The total cost (t) after 8% sales tax is added to an item's price (p): 1.08p=t c.The number of marbles each sister gets (x) when m marbles are shared equally among four sisters: x=m4 d.The volume (V) of a rectangular prism whose height is 12 cm and base is a square with side lengths s cm: V=12s2 Problem 3
Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:
Equation: y = mx
[tex]\frac{y}{x}[/tex] = m
m is a constant value, which means is the same.
A. Equation: 120 - x = L
Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.
B. Equation: 1.08p = t
Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.
[tex]\frac{t}{p}=1.08[/tex]
C. Equation: [tex]x=\frac{m}{4}[/tex]
This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:
[tex]\frac{m}{x}=4[/tex]
D. Equation: [tex]V=12s^{2}[/tex]
This equation is NOT proportional because side length is squared, so it is not constant linearly.

What is the approximate circumference of the pizza?
Answer:
47.1cm
Step-by-step explanation:
multiply 15 cm by 3.14
Given parameters:
Radius of the pizza = 15cm
[tex]\pi[/tex] = 3.14
Unknown:
Approximate circumference of the pizza = ?
Solution:
The pizza is circular and we take the circumference of a circle to find that of the pizza;
Circumference of a circle = 2 [tex]\pi[/tex] r
Input the parameters and solve;
Circumference of a circle = 2 x 3.14 x 15 = 94.2cm
The circumference of the pizza is 94.2cm

Given: Y is the midpoint of XZ
Prove: XY = 1/2 XZ
Statements
Reasons
Answer:
The proposition If Y is the midpoint of XZ, then XY = 1/2 XZ is true.
Step-by-step explanation:
We proceed to present the demonstration of the following proposition:
If Y is the midpoint of XZ, then XY = 1/2 XZ.
1) Y is the midpoint of XZ. Given.
2) [tex]XY + YZ = XZ[/tex] Definition of line segment.
3) [tex]XY = YZ[/tex] By 1)
4) [tex]2\cdot XY = XZ[/tex] 3) in 2)
5) [tex]XY = \frac{1}{2}\cdot XZ[/tex] Algebra/Result
Therefore, the proposition If Y is the midpoint of XZ, then XY = 1/2 XZ is true.

If the radius of the circle is 5 inches, what is the diameter?
10 inches
5 inches
25 inches
2.5 inches
Answer:
10 Inches
Step-by-step explanation:
Remember the radius is always half the diameter. So, r * 2 = d. Plug those in...
5 * 2 = 10.
Therefore, the answer is 10 inches.
3/9 can also simplify to.....

1/3
Answer:
1/3
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation: 3/9 can be divided by 3 on top and bottom so 3/9=1/3 because 1 times 3 is 3 and 3 times 3 is 9 which would equal 3/9.
Which can represent the intersection of a line and a plane.

Find the value of x.
1)
59
(6x + 5)
Answer:
Is 59 equal to (6x + 5)?
If so than your answer is: x = 9 [The value of x is 9]
Explanation:
Given 59 = (6x + 5), x is the value that makes 59 = 59.
Therefore:
59 = (6x + 5)
*given*
59 =(6x + 5)
-5 -5
*subtraction property of equality*
54 = 6x
÷6 ÷6
*division property of equality*
9 = x
x = 9
*symmetric property of equality*
_________________________
To check just substitute, simplify, and make sure 59 = 59:
x = 9 → 59 = (6x + 5) → 59 = (6(9) + 5) → 59 = (54 + 5) → 59 = 59

As an accountant, you have calculated income taxes for a customer for the last 3 years. During those three years, the customer made a tax payment of $1,250, received a tax refund of $550, and made a tax payment of $925. The customer also paid a processing fee of $60 each year.
Answer:
The total amount customer paid during those 3 years is $1685
Step-by-step explanation:
We are supposed to find the total amount customer paid during those 3 years
Customer made a tax payment = $1250
He received a refund of amount = 550
So, amount paid by him = 1250-550
Amount paid by him ==700
Now again He made a tax payment = $925
Processing fee = $60
So, Total Amount paid by him =700+925+60
Total Amount paid by him =1685
Hence the total amount customer paid during those 3 years is $1685

Step 1: Write inequality
5x - 10 ≤ 20
Step 2: Solve for x
Add 10 to both sides: 5x ≤ 30Divide both sides by 5: x ≤ 6Here we see that any value less than or equal to 6 would work.

C5.3 PA9Fitbands' estimated sales are: October $131,982 November $195,723 December $249,283 January $124,298 February $124,284 March $124, 273 What are the balances in accounts receivable for January, February, and March if 65% of sales are collected in the month of sale, 25% is collected the month after the sale, and 10% is the second month after the sale?
Answer:
Accounts receivable in January = $68,432.60
Accounts receivable in February = $55,929.20
Accounts receivable in March = $55,958.95
Step-by-step explanation:
65% of sales collected in the month of sales + 25% in the following month + 10% in second month after sales.
In January, total accounts receivable will be the amounts outstanding or unpaid by the end of January. By the end of January, a total of 10% of December sales & 35% of January sales remain outstanding.
Accounts receivable in January = 35% of January sales + 10% of December sales
Accounts receivable in January = (35% * $124298) + (10% * $249283)
Accounts receivable in January = $43504.3 + $24928.3
Accounts receivable in January = $68432.60
In February, total accounts receivable will be the amounts outstanding or unpaid by the end of February. By the end of February, a total of 10% of January sales & 35% of February sales remain outstanding.
Accounts receivable in February = 35% of February sales + 10% of January sales
Accounts receivable in February = (35% * $124284) + (10% * $124298)
Accounts receivable in February = $43,499.4 + $12,429.8
Accounts receivable in February = $55,929.20
In March, total accounts receivable will be the amounts outstanding or unpaid by the end of march. By the end of March, a total of 10% of February sales & 35% of March sales remain outstanding.
Accounts receivable in March = 35% of March sales + 10% of February sales
Accounts receivable in March = (35% * $124373) + (10% * $124284)
Accounts receivable in March = $43530.55 + $12428.4
Accounts receivable in March = $55,958.95
