Answer:
Equation: 2x + 5 + 6x + 15 = 92
Solution: x = 9
m∠A =23° m∠B = 69°
Step-by-step explanation:
measure of ∠B = 3(2x + 5) = 6x + 15
The sum of the angles = 92 = 2x + 5 + 6x + 15
92 = 8x + 20
72 = 8x
x = 9
m∠A = 2(9) + 5 = 18 + 5 = 23
m∠B = 6(9) + 15 = 54 + 15 = 69
Check: 23 + 69 = 92 and 23(3) = 69
Answer:
The extra hours is 12 hours
Step-by-step explanation:
We are given
She has already saved up $50 for the dress
and this is equation of line
so, y-intercept is 50
![b=50](https://tex.z-dn.net/?f=b%3D50)
now, we can find slope
we can select any two points and then we can find slope
x1=0 , y1=50
x2=2 , y2=75
now, we can use formula
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
now, we can plug values
![m=\frac{75-50}{2-0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B75-50%7D%7B2-0%7D)
![m=\frac{25}{2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B25%7D%7B2%7D)
now, we can find equation
y=mx+b
![y=\frac{25}{2}x+50](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B25%7D%7B2%7Dx%2B50)
we are given y=200
so, we can set it to 200 and then we can solve for x
![200=\frac{25}{2}x+50](https://tex.z-dn.net/?f=200%3D%5Cfrac%7B25%7D%7B2%7Dx%2B50)
![\frac{25}{2}x=150](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B2%7Dx%3D150)
![25x=300](https://tex.z-dn.net/?f=25x%3D300)
![x=12](https://tex.z-dn.net/?f=x%3D12)
