Solve this system of equations by using the elimination method -2x-2y=-6, 3x+4y=8
Step-by-step explanation:
- 2x-2y=-6
3x+4y=8
multiply equation (1) by 3 and equation (2) by 2
- 6x-6y=18
6x+8y=16
Add
2y=34
y= 34÷2
y=17
substitute 17 for y in equation (2)
3x+4y=8
3x+4(17)=8
3x+68=8
3x=8-68
3x=-60
x=-60÷3
x=-20
x=-20,y=17

Mr. Linx and Mrs. Lynn both work for the same company, but they do not have the the same hourly wages. Together they make $32.50 per hour. This week, Mr. Linx (x) worked 35 hours, and Mrs. Lynn (y) worked 37 hours. Together, they made $1,172.50.
Answer:
Mr. Linx wages = x = $15
Mrs. Lynn wages = y = $17.50
Step-by-step explanation:
Mr. Linx wages = x
Mrs. Lynn wages = y
x + y = 32.50 (1)
35x + 37y = 1,172.50 (2)
From (1)
x = 32.50 - y
Substitute x = 32.50 - y into (2)
35x + 37y = 1,172.50
35(32.50 - y) + 37y = 1172.50
1137.5 - 35y + 37y = 1172.50
- 35y + 37y = 1172.50 - 1137.50
2y = 35
y = 35/2
y = 17.50
Substitute y = 17.50 into (1)
x + y = 32.50
x + 17.50 = 32.50
x = 32.50 - 17.50
x = 15
Mr. Linx wages = x = $15
Mrs. Lynn wages = y = $17.50
Find x and y with ray theorem
Answer:
x = 12 and y = 9
Step-by-step explanation:
Using the similarity theorem to fid the value of x and y
16/x = 16+6/16.5
16/x = 22/16.5
22x = 16*16.5
22x = 264
x = 264/22
x =12
Similarly
24/x = 24+y/16.5
24/12 = 24+y/16.5
2 = 24+y/16.5
24+y = 2 * 16.5
24+y = 33
y = 33-24
y = 9
Hence x = 12 and y = 9

The official all-time high temperature in Osoyoos, B.C., was 43°C in July 1998. The official all-time low temperature was –21°C in February 1996. What is the difference between the two temperatures? Please show all your work.
Answer: 64°C
Step-by-step explanation:
Official all-time high temperature = 43°C
Official all-time low temperature = –21°C
The difference between the two temperatures will be calculated by subtracting the low temperature from the high temperature. This will be:
= 43°C - (-21°C)
= 43°C + 21°C
= 64°C

Given A(8,3), B(4,8), C(4,4) and D(8,-1) find the slope of AB
Answer:
Step-by-step explanation:
Slope: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in A(8,3) and B(4,8)
[tex]=\frac{8-3}{4-8} \\=\frac{5}{-4}\\=-\frac{5}{4}[/tex]
Therefore, the slope of AB is [tex]-\frac{5}{4}[/tex].

A circle has diameter 12. What's the circumference?
a
24π
b
12π
c
36π
d
144π
Answer:
b. 12π
Step-by-step explanation:
C= 2πr
R= D/2= 12/2= 6
C= 2x3.14x6
2x6= 12
C= 12π
Given :-
diameter of circle = 12Then,
Radius will be circle= 12/2 = 6ExplanationUsing Formula
★Circumference of circle = 2πr
Keep Value
==> Circumference of circle = 2π × 6
==> Circumference of circle = 12π
Henceyour answer will be option number b.- 6

Tina is cutting construction paper into rectangles for a project. She needs to cut one rectangle that is 15 inches × 12 1/3 inches. She needs to cut another rectangle that is 10 1/4 inches by 10 1/3 inches. How many total square inches of construction paper does Tina need for her project?
Answer:
Step-by-step explanation:
Remark
This is an "in theory" type of question. She's going to actually need a little more.
Area 1
L = 15
W = 12 1/3
Area = L*W
Area = 15 * 12 1/3 I wonder if you know what the distributive property is. I'll try it. If you don't understand, leave a remark
Area = 15 * (12 + 1/3) Multiply both parts by 15
Area = 15*12 + 1/3 * 15
Area = 180 + 5
Area = 185 square inches.
Area 2.
This is a little harder because their are
2 fractions.
The easy way to do this is change to decimals
L = 10 1/3 = 10.33333333
W = 10 1/4 = 10.25
Area = 10.3333333 * 10.25
Area = 105.92 Add
Total Area
The total area = 290.92
