HELP! My teacher didn't teach half the material! How do I do this!?!?!?!

Sladkaya [172]

Answer:

Step-by-step explanation:

1-(-7.2x+3.5)=5+3(7.4x-1) first parenthesis

1+7.2x-3.5=5+22.2x-3

7.2x-2.5=2+22.2x (x on one side and numbers on other)

22.2x-7.2x= -2-2.5

15x=4.5 divide by 15

x=-4.5/15

How to check division with multplication<br><img src="https://tex.z-dn.net/?f=3%20%5Ctimes%20292%20" id="TexFormula1" title="3 \

svetoff [14.1K]

Answer: By cross multiplication.

Step-by-step explanation: Given product is 3 × 292.

We know that after simple multiplication, we get 3 × 292 = 876.

Now, to check division with multiplication, either we need to divide 876 by 3 to get the answer 292,

we need to divide 876 by 292 to get the answer 3.

We will do that as follows -

$\dfrac{876}{3}=292~~~\textup{and}~~~\dfrac{876}{292}=3.$

Thus, doing cross-multiplication, we arrive at our conclusion.
