Answer:

5.3 ft

Step-by-step explanation:

Because CD corresponds to BC, the scale factor from triangle ABC to triangle CDE, is 7/8. Now, DE corresponds to AB, so to get DE, we must multiply the value of AB by 7/8. 6 times 7/8 is 5.25, and rounding to the nearest tenth of a foot, the value of DE is 5.3.

511 = -7 (10x – 13)<br> steps

PilotLPTM [1.2K]

Answer: $x=-6$

<u>Simplify both sides of the equation</u>

<u></u> $511=(-7)(10x)+(-7)(-13)(Distribute)\\511=-70x+91$ <u></u>

<u></u>

<u>Flip the equation</u>

<u></u> $-70x+91=511$ <u></u>

<u></u>

<u>Subtract 91 from both sides</u>

<u></u> $-70x+91-91=511-91\\-70x=420$ <u></u>

<u></u>

<u>Divide both sides by -70</u>

<u></u> $-70x/70=420/-70\\x=-6$ <u></u>
