Answer:
(7, 10.5)
Step-by-step explanation:
just going to use substitution here.
so you would substitute the y value in the equation x-2y=-14 with 2x-3.5.
it should look like: x-2(2x-3.5)=-14
solve the equation and you get x=7.
plug in 7 for x in either equation and you get y= 10.5.
Answer:
68 is what I'm getting for x
70 is the correct length of DH
Step-by-step explanation:
You can set up the proportion for this question.
99.2 / 62 = 112/(x + 2) Cross multiply
99.2 ( x + 2) = 62 * 112 Combine the right side
99.2(x + 2) = 6944 Use the distributive principle to remove the brackets.
99.2*x + 2*99.2 = 6944 Combine the factors on the left
99.2x + 198.4 = 6944 Subtract 198.4 from both sides
99.2x = 6944 - 198.4 Combine the terms on the right
99.2x = 6745.6 Divide both sides by 99.2
x = 6745.6/99.2
x = 68
DH = 70
