( x - 7 )/ ( x - 2 ) = 5/4 , Therefore x = -------------
skad [1K]

Answer:

x = -18

Explanation:

To solve this problem easily, we can cross multiply. You would multiply the numerator of the first fraction by the denominator of the second, and multiply the numerator of the second fraction by the denominator of the first. In this case, (x-7) would be multiplied by 4 and 5 would be multiplied by (x-2). The answers from these two calculations would each be one side of the equation.

After doing this, you can solve and isolate x.

Work is shown in the attached picture.

How does this work help me please
Paha777 [63]

Answer:

a) Requires you to plot the point on the graph so you'll just have to plot (4,2600) using the graph

c) Here they have given the years as 3.5, using this inorder to determine our value we need to draw a straight line upwards from (3.5,0) and keep extending until it touches the graph.Then draw another line from the point where it touches horizontally toward the left until it cuts the yaxis and that will be your value answer

I hope it's clear I'm really sorry it's so hard to explain in words.

Btw if you could mark it as brainliest that would be great ^^
