Answer:

A = 6

Step-by-step explanation:

First, use the distributive property on the left side:

4(3A - 4) =56\\12A - 16 = 56

Add 16 to both sides

12A = 72

divide both sides by 12

A = 6

8. By area, the former U.S.S.R. was the largest country, having 8.649x106 square miles of land. At this time Canada was the seco
ivanzaharov [21]

Answer:

Canada was 418.912 sq miles smaller than the USSR.

Step-by-step explanation:

Note: I don't know if this question required a calculator so I'll answer without one.

Symbols:

  • USSR area in sq miles = u
  • Canada area in square miles = c

u<em> </em>= 8.649×106

c<em> </em>= 4.797×106

x = how much less area

u<em> </em>= c + x

  • USSR area = Canada area + number of sq miles less

Math:

u = c + x

  • plug in values

8.649×106 = 4.797×106 + x

  • divide by 106 to get rid of the ridiculously large numbers.

8.649 = 4.797 + \frac{x}{106}

  • subtract (use calculator or just traditional subtraction methods)

3.952 = \frac{x}{106}

  • multiply both sides by 106 (use calculator or traditional methods)

418.912 = x

A group of friends equally split the dinner bill shown. If each person paid $16, how many friends paid?
Akimi4 [234]

Answer:

16/y = x

Step-by-step explanation:

You cannot solve for the question yet. However, you can create an equation!

we know that each person paid 16 dollars.

We don’t know how much the bill was or how many people were there.

So out equation looks like;

z/y = x

or

z * x = y

z = how much each person paid.

y = how much each person paid.

x = how many people paid.

Substitute with what we know.

16/y = x

16 * x = y

Now you will be able to substitute for either x or y to find either answer.
