Answer:
x=4,y=2
Step-by-step explanation:
3x-2y=8 ..........1
2x+y=10...........2
multiply equation 2 by 2 and adding equation 1 and 2 ,we get
3x-2y=8
4x+2y=20
+_________
7x=28
x=28/7=4
:.x=4
again substituting value of x in equation 1 we get
3×4-2y=8
12-8=2y
y=4/2=2
:.y=2

The circle graph shows how a family spends its annual income. If $37,800 is used for Housing and Clothing combined, what is the total annual
income?
Answer:
$90000
Step-by-step explanation:
From the pie chart,
Let the total annual income = $y
The percentage of housing = 28 %
The percentage of clothing = 14 %
The combined percentage of housing and clothing = 28+14 = 42 %
If the amount spent on both housing and clothing combined = $ 37800
Therefore,
y(42/100) = 37800
Solve for y
42y = 37800×100
42y = 3780000
y = 3780000/42
y = $90000
Hence, the total annual income is $90000

Answer:

Step-by-step explanation:
cost of tank tops
20 / 5 = $4 each
cost of t-shirts
35 / 5 = $7 each
7 - 4 = $3
Answer:
$3
Step-by-step explanation:
1.Approach
To solve this problem, one must first find the cost of each product. This can be done by diving the price by the amount of each product. After finding the unit price of each product, one will subtract the cost of the tank-top from the cost of the t-shirt.
2.The unit price of a t-shirt
It is the given that 5 t-shirts cost $35. Divide the price of the shirts by the number of shirts to find the cost of each individual shirt.
35 ÷ 5 = 7
Each individual t-shirt costs $7.
3.The unit price of a tank-top
It is given that 5 tank-tops cost $20. Divide the price of the tank-tops by the number of tank-tops to fund the unit price of each tank-top.
20 ÷ 5 = 4
Each tank-top costs $4.
4.Find out how much more each shirt costs
Now subtract the price of the unit price of the tank-top from the unit price of the t-shirt.
(t-shirt) - (tank-top)
= 7 - 4
= 3

Answer: To get 24
Step-by-step explanation
What you would need to do is first multiply 12 x 5 would come out as 60.
Then from 60 you subtract 17 and 12 to get 5. Divide by the 5 that you just got from 17 and 12 and to get 20. Using the 4 add it to the 20 to get 24.

For the equation y - 3 = -2(x + 1) the line has a slope of -2 and
contains what point
Answer:
(0, -2) --> Y-Intercept
Step-by-step explanation:
y - 3 = -2( x + 1 )
y - 3 = -2x - 2
y= -2x -2
Y-Intercept = (0,y)
= (0, -2)

[tex]m = \frac{2}{3} [/tex]
Step-by-step explanation:-
[tex]( - 2, - 1) = (x {1} ,y {1}) [/tex]
[tex](4,3) = (x{2} ,y{2} )[/tex]
BY USING SLOPE OF LINE FORMULA
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
[tex]m = \frac{(3 - ( - 1))}{(4 - ( - 2))} [/tex]
[tex]m = \frac{(3 + 1)}{(4 + 2)} [/tex]
[tex]m = \frac{4}{6} [/tex]
[tex]m = \frac{2}{3} [/tex]

Step-by-step explanation:
A pack of 4 rolls of Charmin cost $3.64. A pack of 32 rolls of Charmin cost $20.80. How much cheaper per roll is it to purchase the bigger pack?
Answer:
.26 cents cheaper a roll

Point A is at (3,5). After being translated 10 units down, what are the coordinates of Point A?
Answer: The required co-ordinates of the new point are (6, 5).
Step-by-step explanation: Given that the point (-3, 15) undergoes a translation of 9 units right and 10 units down.
We are to find the coordinates of the new point.
We know that
if the point (x, y) undergoes a translation of 9 units right and 10 units down, then its translation rule is given by
(x, y) ⇒ (x+9, y-10).
Therefore, the co-ordinates of he new point are given by
(-3, 15) ⇒ (-3+9, 15-10) = (6, 5).
Thus, the required coordinates of the new point are (6, 5).
6th grade work please tell me the answer fast and don’t give me and incorrect one
Answer: 222cm
Step-by-step explanation:
To find the area of this composite shape you will have to split them into 2 shapes; a rectangle and a triangle.
To work out the area of the rectangle you have to do 15×12= 180
Then, to work out the area of the triangle, you use the formula base times height divided by 2.
7×12=84
84÷2=42
Then to work out the total area of both the rectangle and the triangle, you have to add the area of both.
180+42=222cm
Hope this helps :)
