HELP ASAPPPPP PLZZZZ Question in pic!!!!!
Step-by-step explanation:
Given
5y + 68 = 3y + 96 (vertically opposite angles) and
3x + 18 = 5x + 2 (vertically opposite angles)
Now solve for x.
[tex]3x + 18 = 5x + 2 \\ 3x + 18 - 5x = 2 \\ - 2x + 18 = 2 \\ - 2x = 2 - 18 \\ - 2x = - 16 \\ x = - 16 \div - 2 \\ = 8[/tex]
Now Solve for y.
[tex]5y + 68 = 3y + 96 \\ 5y + 68 - 3y = 96 \\ 2y + 68 = 96 \\ 2y = 96 - 68 \\ 2y = 28 \\ y = 14[/tex]

Solve for x, then find the m HED. Please helppp
Answer:
x=3, HED =39
Step-by-step explanation:
Solution :
[tex]10x + 21 + 13x = 90[/tex]
[tex]23x = 90 - 21[/tex]
[tex]23x = 69 = > x = 3[/tex]
Angle HED = 13 × 3 = 39°
Hope this helps!

find the slope-intercept equation of the line that passes through (0,1) and has a slope of -2/3
Answer:
y = -2/3x + 1
Step-by-step explanation:
We already know the slope, so all we need to do is find the y-intercept. To find that, we need to plug the coordinates into the equation so far, which is,
y = -2/3x + b
1 = -2/3(0) + b
1 = 0 +b
1 = b
So the equation is y = -2/3x + 1

What is x-2.3y=0.6 -x+5.1y=-6.2
5. Find the length of the side denoted b "y" to the nearest tenth.
Answer:
y = 24√3, or approximately 41.6
Step-by-step explanation: √3 36
Here the ratio 36/y = cosine of 30 degrees = ------- = ------
2 y
Cross-multiplying yields (√3)y = 72, so y = 72/√3, or 72√3/3, or y = 24√3

170% of what number is 40?
Provide and exact fraction answer
Answer: 23.53
Step-by-step explanation:
We have, 170% × x = 40

170
100
× x = 40
Multiplying both sides by 100 and dividing both sides by 170,
we have x = 40 ×
100
170
x = 23.53
If you are using a calculator, simply enter 40×100÷170, which will give you the answer.
