3/2+2x/5=7/10

We simplify the equation to the form, which is simple to understand
3/2+2x/5=7/10

Simplifying:
+1.5+2x/5=7/10

Simplifying:
+1.5 + 0.4x=7/10

Simplifying:
+1.5 + 0.4x=0.7

We move all terms containing x to the left and all other terms to the right.
 + 0.4x=0.7-1.5

We simplify left and right side of the equation.
 + 0.4x=-0.8

We divide both sides of the equation by 0.4 to get x.
x=-2

A survey was given to 339 people asking whether people like dogs and/or cats.

liubo4ka [24]

Answer:

80.

Step-by-step explanation:

Let $C$ be the set of people who like cats and $D$ the set of people who like dogs. Under the cardinality theorem you have

n(CUD) = n(C) + n(D) - n(CnD)[/tex], isolating the $(C$ ∩ $(D$ , you have n $(C$ ∩ $(D$ = n(C) + n(D) - $(C$ ∪ $.As a total of 339 individuals, and 88 are those who do not like cats or dogs, then 251 of them are those who like cats or dogs. Then, n[tex](C$ ∩ $(D$ $= 190 +141 -251 = 80$

Colby wants to set up square tiles on the top of a wooden box. The top of the wooden box is a rectangle 7 1/2 inches long and 5

Andrei [34K]

Yes he can, because when the area of the top of the box is divided by 3/4, you get a whole number, meaning there would be no tile pieces left over, which means that he could cover the top. SEE PICTURE FOR WORK.
