Answer: 7. 35, 8. 42.50

Step-by-step explanation:

7. First, convert 4 3/8 to an improper fractoin.

4 3/8 = 35/8

Now divide 35/8 by 1/8 and you get 35.

8. Each ounce increased 5 dollars, so 8.5 ounces increased 8.5*5 dollars = $42.50

It's easiest to start with the point-slope form of an equation, $y-y_1=m(x-x_1)$ , where m is the slope and $(x_1, y_1)$ is the point given.

We have m = 3, $x_1 = 5$ , and $y_1 = 10$ .

We plug in these values to get
$y-10=3(x-5)$ .

We now rearrange to get this into slope-intercept form, $y=mx+b$ , by solving for y.

$y=3(x-5)+10\\y=3x-15$

Step-by-step explanation:

im just taking a guess.

x+4>-12

-4 -4

---------------

4's cancel out and -12+-4=-16

Again this is just a guess.

Fantom [35]

Answer:

x = 8, y = 1

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{4}{y}$ = $\frac{4}{1}$ ( cross- multiply )

4y = 4 ( divide both sides by 4 )

y = 1

Also

$\frac{x}{2}$ = $\frac{4}{1}$ ( cross- multiply )

x = 8

Raul has 56 bouncy balls

he puts the balls into red gift bags and green gift bags

so lets say he puts x number of balls into green gift bags

then we are told that he puts three times as many balls into red gift bags as he puts into green gift bags

so the number of balls he puts into red gift bags is - 3 * x = 3x

the total number of balls = 56

so we can write the following equation

x + 3x = 56

4x = 56

x = 56/4

x = 14

therefore the amount of balls he puts into green bags is - 14 balls
