Answer:
the solution is x = 2 and y = 4 OR (2,4)
Step-by-step explanation:
From the question
Equation 1: 3x-2y= -2
Equation 2: 3x + y = 10
Subtract equation 1 from equation 2, that is
3x + y = 10 - (3x -2y = -2)
You get
3x - 3x + y - (-2y) = 10 - (-2)
0 + y + 2y = 10 + 2
3y = 12
Divide both sides by 3
∴ y = 12/3
y = 4
Substitute the value of y into equation 2 to get x
3x + y = 10
3x + 4 = 10
Then,
3x = 10 - 4
3x = 6
Divide both sides by 3
∴ x = 6/3
x = 2
Hence, the solution is x = 2 and y = 4

Bob can paint a fence in 12 hours, and working with Jen can paint a fence in 4 hours. How long would it have taken Jen to paint the fence alone?
Answer:
6 hours
Step-by-step explanation:
For Bob
12 hours = 1 fence
1 hour = 1/12 fence
Together Bob and Jen
4 hours = 1 fence
1 hour = 1/4 fence
Now, for Jen:
1 hour = 1/4 - 1/12= 3/12 - 1/12 = 2/12=1/6
Find the amount of time Jen will need:
1/6 fence = 1 hour
1 fence = 6 hour

What is the measure of the internal angle H' of the image in degrees
Answer:
40 degrees
Step-by-step explanation:
- All internal angles of a triangle add up to 180 degrees.
- A right angle is 90 degrees.
90+50=140
subtract 140 from 180, which is 40 degrees.
The bottom edge of a 16-foot long cantilever is given by the equation y = 2Vx, where y is the distance the
bottom edge is from ground height, in feet.

(a) What is the value of b, the height of the
cantilever, in feet?
b
T
y=2&x
b) To the nearest tenth of a foot, what is the
thickness, T, of the cantilever at x =6 feet?
Answer:
[tex](a)\ b = 8[/tex]
[tex](b)\ T = 3.1[/tex]
Step-by-step explanation:
Given
[tex]y = 2\sqrt x[/tex]
See attachment
Solving (a): Find b
At point b, [tex]x = 16[/tex]
So, the value of b is:
[tex]b = 2 * \sqrt{16[/tex]
[tex]b = 2 * 4[/tex]
[tex]b = 8[/tex]
Solving (b): Find T
First, we calculate the value of y at point T
[tex]y = 2\sqrt x[/tex]
At point T, [tex]x = 6[/tex]
So:
[tex]y = 2 * \sqrt 6[/tex]
[tex]y = 2 * 2.45[/tex]
[tex]y = 4.9[/tex]
To calculate T, we subtract the calculated height (y) from the value of b
[tex]T =b - y[/tex]
[tex]T = 8 - 4.9[/tex]
[tex]T = 3.1[/tex]
Which is NOT true?
A
16 + 3 = 11 + 8
В.
16 = 16
C.
16 - 4 = 7 + 6
D
16 = 19-3
Answer:
C. 16 - 4 = 7 + 6
Step-by-step explanation:
16 - 4 = 12
7 + 6 = 13
12 does not equal 13.
Hope this helps! :)
Answer:
C
Step-by-step explanation:
A is true because 16 + 3 = 19 and 11 + 8 = 19
B is true because 16 = 16
C is Not true because 16 - 4 = 12 and 7 + 6 = 13
D is true because 19 - 3 = 16
