3x + (x+3) = 19
4x + 3 = 19
4x = 16
x = 4
y= x+3
y= 4+3
y= 7
2nd one is the correct one I think
Answer:
A
Step-by-step explanation:
supplementary angles add up to 180
angle cgr and kga are vertical angles so they are equal
that makes the two angles in question add up to 180
0.7 and 14/20 are two different ways to say 7/20
Answer:
Ratio of sweaters to dresses = 8 : 5
Sum of ratios = 13
Let number of sweater + dresses = x
![number \ of \ sweaters = \frac{8}{13} *x\\\\24 = \frac{8}{13}*x\\\\x = \frac{24*13}{8} = 3*13 = 39](https://tex.z-dn.net/?f=number%20%5C%20of%20%5C%20sweaters%20%3D%20%5Cfrac%7B8%7D%7B13%7D%20%2Ax%5C%5C%5C%5C24%20%3D%20%5Cfrac%7B8%7D%7B13%7D%2Ax%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B24%2A13%7D%7B8%7D%20%3D%203%2A13%20%3D%2039)
![number \ of \ dresses = 39 - 24 = 15](https://tex.z-dn.net/?f=number%20%5C%20of%20%5C%20dresses%20%3D%2039%20-%2024%20%3D%2015)
