I need answers for 4 and 6

Hello! I can help you with this!

4.
a. $100
b. $360

The formula to find the answers to these kinds of problems is p * r * t. The rate is always a decimal, so if the rate is 8%, you multiply by 0.08. If the rate is 12%, you multiply by 0.12, and so on.

5.
a. 12.8
b. 31 1/6

I got these answers by doing the distributive property. Replace each variable with the number it represents, multiply each by two and add them up to get these answers. For the fraction one, you can set up each fraction by finding the LCD before multiplying by 2, or you can find a fraction calculator online and add the numbers up.

6.
a. x = 20
b. x = 3
c. x = 13
d. x = 0
e. x = 4
f. x = 7
g. x = -3

I solved this problem by doing the distributive property and doing these kinds of problems step by step. It’s long to explain, but hopefully your teacher has good notes for you to look back on over these types of questions. If there is only a negative sign in front of the distributive property equation, then you basically distribute -1 to each number. In these long equations, combine like terms. You must do these kinds of questions right, because it’s easy to mess up and get wrong answers if you don’t do the right steps in order.

Of course! so basically for each value of x, for example -6, plug it into the equation. so for -6 do -2/3(-6)+7. hope this helps!

For each equation, determine whether it represents a direct variation, an inverse variation, or neither.
icang [17]

For the first question which is y=x/3, here as we see that both are in top. So they represents direct variation and constant of variation is 1/3 .

For the second question , which is 6/y=x, y is denominator and x is in the denominator. So they represents inverse variation and the constant of proportionality is 6 here .

Two regular hexagons are similar. answers- ALWAYS, SOMETIMES, or NEVER
ankoles [38]

Answer:

Always

Step-by-step explanation:

Some people might mistaken it for sometimes, but the part that makes it always is when it says "regular" hexagons.

Similarity is defined by having congruent angles and proportional sides. Regular hexagons will always have internal angles of 60°, meaning that any two regular hexagons will always be similar.
