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
Yes, this is a linear equation with a constant rate of change (a slope) so the sets of values of the graph are proportional
You can look it up on Math.com or some kind of math website. There are plenty of options. Also, there are practice tests that you can take to see if you understand the subject.
((5x-4)+(6x-2))/2= 4x.
set it up like that because the equation to find the medium of a trapezoid is:base+base/2 = medium. Hope that helps:)
Answer:
The answer to x is 7
Step-by-step explanation:
because 4x7 is 28 and + 4 = 36
