Chelsea and her friends are making small fruit baskets for their neighbors. They have 90 pears, 45 peaches, and 75 apples. What

iVinArrow [24]

Answer:

15 baskets

Step-by-step explanation:

This question is a GCF question

The first step would be to find the factors of 45, 75 and 90

The factors of 45 are: 1, 3, 5, 9, 15, 45

The factors of 75 are: 1, 3, 5, 15, 25, 75

The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

The greatest common factor is 15.

Therefore, the greatest number of baskets they can make if each basket has the same number of pears, the same number of peaches, and same number of apples, with no fruit leftover is 15 baskets

Help me plzzzzzzzzz<br> solve for x

Svet_ta [14]

Answer:

$7) \frac{x+20}{x}=\frac{46}{30}$

$30(x+20)=46x$

$30x+600=46x$

$46x-30x=600$

$16x=600$

$x=75/2$

$x=37.5$

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

$8) \frac{10}{3x+1} =\frac{22}{7x-1}$

$10(7x-1)=22(3x+1)$

$70x-10=66x+22$

$70x-66x=22+10$

$4x=32$

$x=\frac{32}{4}$

$x=8$

<u>---------------------</u>

hope it helps...

have a great day!!

Find the inverse of the function and then determine whether the inverse is a function.

klemol [59]

as you already know, we start off by doing a quick switcheroo on the variables, and then we solve for y to get the inverse,

$\bf y=x^2+4\implies \stackrel{switcheroo}{x = y^2+4}\implies x-4=y^2\implies \pm\sqrt{x-4}=\stackrel{f^{-1}(x)}{y}$

and if you run a vertical line test on that expression, you'll find that it doesn't pass it, meaning is not a function.
