Find the value of x and y in the parallelogram below.
Answers
Answer:
x=7
y=-17
Step-by-step explanation:
Lets do 10x-7. Basically it will be equal to 63, so the equation will be 10x-7=63
to find x we need to add 63+7=70 and put 10x with an equal sign which is 70=10x
7=x because 70/10=7.
in a simple way it is
10x-7=63
10x=7+63=70
10x=70
x=7
Lets do -5y+3. It is equal to 88.
so it will be
-5y+3=88
-5y=88-3=85
-5y=85
y=-17
Answer:
[tex]\Longrightarrow: \boxed{\sf{x=7, \ y=-17}}[/tex]
Step-by-step explanation:
To find the value of x and y in the parallelogram, you have to isolate it on one side of the equation.
10x-7=63First, add by 7 from both sides.
10x-7+7=63+7
Solve.
Add the numbers from left to right.
63+7=70
10x=70
Then, you divide by 10 from both sides.
10x/10=70/10
Solve.
Divide these numbers goes from left to right.
70/10=7
[tex]\Longrightarrow: \boxed{\sf{x=7}}[/tex]
-5y+3=88Subtract by 3 from both sides.
-5y+3-3=88-3
Solve.
Subtract the numbers from left to right.
88-3=85
-5y=85
Divide by -5 from both sides.
-5y/-5=85/-5
Solve.
Divide the numbers from left to right.
85/-5=-17
[tex]\Longrightarrow: \boxed{\sf{y=-17}}[/tex]
Therefore, the correct answer is x=7 and y=-17.I hope this helps. Let me know if you have any questions.

will the product of two numbers incrase of decrease, and by what percent if one of them is increased by 50% and the other is decreasedd by 50%?
Answers
Let B represent the number that is decreed by 50%
A = 1 + (50/100)
A = 1.5
B = 1 - (50/100)
B = 0.5
(1.5A)*(0.5B) = 0.75AB.
0.75AB/AB
= 0.75 or 75%.
= 100% - 75% = 25% Decrease
Therefore, the product of two numbers if one of them is increased by 50%, and the other is decreased by 50% will decrease by 25%

Y=-1x+5
Slope intercept form is y=mx+b
m = slope
b = y intercept
As you can see from the line, the y-intercept if 5, so b is 5. To find the slope, we take two points, I'm using (0,5) and (2,3), and then divide change y by change in x or y2-y1 / x2-x1
3-5 / 2-0
= -2/2= -1
The slope is -1, so m is -1.

2) X + Z = 20
3) Y + Z = 24
what is X + Y + Z = ?
From equation 1, x = 10-y
Plug 10-y in place of x in equation 2
10-y+z = 20 subtract 10 from both sides
-y + z = 10
We now have 2 equations with just y and z
-y + z = 10 new equation
y + z = 24 add the 2 equations
--------------
2z = 34
z = 34/2
z = 17
We now have the value of z.
Plug that into equation 3
y + z = 24
y + 17 = 24
y = 24-17
y = 7
We now have the value of both z and y.
Plug the value for y into equation 1 to find x
x + y = 10
x + 7 = 10
x = 10-7
x = 3
Your values are x = 3, y = 7, z = 17

A painter paid by the hour.if he is paid R360 for 12 hours how much will he be paid for 9 hours
Answers
Answer:
Step-by-step explanation: . Paid to the painter for 12 hrs=Rs.360........therefore,......amt paid for 1 hr=360/12=30......... Therefore,.....amt paid for 9 hrs=9*30=Rs.270........hope i helped u:)
The amount paid for 9 hours is R270
How to determine the amount paidThe expression can be represented by using the following ratio
Ratio = Amount : Time
So, we have:
R360 : 12 = Amount : 9
Express as fraction
R360 / 12 = Amount / 9
Multiply both sides by 9
Amount = R360 / 12 * 9
Evaluate the product
Amount = R270
Hence, the amount paid for 9 hours is R270

Ally is buying a speed boat for $10,000 with a down payment of $2,500. The bank approved a simple interest flat rate loan for 5 years at 7% APR. How much are the monthly loan payments? (round to the nearest cent) A) $157.50 B) $168.75 C) $180.00 D) $191.25
Answers
Answer:
B
Step-by-step explanation:
The monthly loan payment should be $168.75.
Calculation of the monthly loan payment;Since Ally is buying a speed boat for $10,000 with a down payment of $2,500. The bank approved a simple interest flat rate loan for 5 years at 7% APR.
The net principal should be
= $10,000 - $2,500
= $7,500
Now simple interest should be
= $7,500(5)(7%)
= $2,625
Now the total amount should be
= $7,500 + $2,625
= $10,125
Now the monthly payment is
[tex]= 10125\div (12\times 5)\\\\= 10125 \div 60[/tex]
= $168.75
Therefore, The monthly loan payment should be $168.75.
