Answer:

FJ=18\ units

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

△FEG is similar with △FHJ -----> by AA Similarity Theorem

so

\frac{FE}{FH}=\frac{FG}{FJ}

we have

FE=HF+EH=12+8=20\ units\\FH=HF=12\ units\\FG=30\ units

substitute the given values

\frac{20}{12}=\frac{30}{FJ}\\\\FJ=12(30)/20\\FJ=18\ units

7 - 2x = 2(x - 4) - 1 solve
Naddika [18.5K]

Answer:

x = 4

Step-by-step explanation:

expand out the brackets to get   7 - 2x = 2x - 8 - 1

we can then add 2x to both sides to get        7  = 4x - 8 - 1

add 9 to both sides to get       16 = 4x

divide both sides by 4 to get     x = 4

hope that helps

Stells [14]

Based on the number of years that Peter and Blair have till retirement, the total amount that they need to save to completely fund their income shortfall is $65,545.72.

<h3>What amount do Peter and Blair need to save?</h3>

First, find the income shortfall:

= 75,017 - 54,000

= $21,017

The amount they need to save to cover this shortfall is the future value of this amount at retirement. The rate will be the real rate which is:

= 6% - 2% inflation

= 4%

The future value is:

= Income shortfall x future value interest factor, 4%, 29 years

= 21,017 x 3.1187

= $65,545.72
