Zarrin [17]2 years ago
4 0

Answer:

x = 11

Step-by-step explanation:

\frac{wvu}{wv}  =  \frac{wg}{wh}  \\  \\  \frac{28}{40}  =  \frac{7}{x = 1}  \\  \\ 28(x - 1) = 40 \times 7 \\  \\ 28 \: x - 28 = 280 \\ 28x = 308 \\ x = 11

Is x = 9 in the solution set of the inequality x + 14 &lt; 20<br> Yes or no
notsponge [240]

Answer: No

Step-by-step explanation:

Data: x+14<20

x=9? Is what your trying to find

<u>Step one, Isolate x by subtracting 14 on both sides</u>

X+14-14<20-14=X=6

Reason: Since you are trying to find if x=9, you have to isolate it. The way to do that is to get rid of +14 by subtracting it by 14. However, since what you do to one side you do to the other, you subtract +20 by 14 to get 6.

Since x=6 isn't x=9, the answer is No

Answer: No

I hope this helps!

Help, please! Thankyou!!!!
alukav5142 [94]

Answer: C

Step-by-step explanation: simply apply the distributive property to each half of the expression to be left with terms that can be combined.

(8x + 16y)/2 = 4x + 8y

4(x - y) = 4x - 4y

(4x + 8y) + (4x - 4y) = 4x + 4x + 8y - 4y

= 8x + 4y => C

Am i given enough info. to determine whether the quadrilateral is a parallelogram? explain
Lorico [155]

This could be a parallelogram, but it also could easily be an isosceles trapezoid. A trapezoid is a figure with only one pair of parallel sides. An isosceles trapezoid is a trapezoid where the non-parallel sides are the same length. It's similar to an isosceles triangle.

Because this could be an isosceles trapezoid, this means we don't have enough information. See the attached image below for an example.
