Answer:

y^2 +8y + 16

Step-by-step explanation:

6y^2 +2y +5 - (5y^2 -6y -11)

I distribute the minus sign

6y^2 +2y +5 - 5y^2 +6y +11

Then I put them vertical.

6y^2 +2y +5

-5y^2 +6y +11

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

y^2 +8y + 16

This is in standard from since the exponential decreases.

Answer:

$- 1.2 , - \frac{1}{2} ,0.44,\frac{7}{3}$

Step-by-step explanation:

We want to arrange the following numbers on the number line in order from least to greatest.

The numbers are:

$0.44, \frac{7}{3} , - 1.2, - \frac{1}{ 2}$

Let us convert everything into decimals to get:

$0.44,2. \bar3 , - 1.2, - 0.5$

Rearranging from least to greatest, we have:

$- 1.2 , - 0.5 ,0.44,2. \bar3$

Brock heard that as a general rule, he should spend no more than one week's pay on rent. If Brock's salary is $25,200 per year,

olasank [31]

There are about 52 weeks in a year, so divide 25200 by 52 (484.6). He gets paid $484.60 per week. So he should spend a maximum of C. $485 on rent per month.

Joseph needs 6 1/2 cups of cooked rice for a recipe of nasi gorang. If 2 cups of uncooked rice with 2 1/2 cups of water make 4 1

liraira [26]

Answer:

The number of the cups of uncooked rice is 3 cups

The number of the cups of water is $3\frac{3}{4}$ cups

Step-by-step explanation:

* Let us read the recipe of Nasi Gorang

- 2 cups of uncooked rice need $2\frac{1}{2}$ cups of water to

make $4\frac{1}{3}$ cups of cooked rice

- Joseph needs $6\frac{1}{2}$ cups of cooked rice

- We need to know how many cups of uncooked rice Joshep needs

for this recipe and how much water should be added

* We can solve this problem by using the ratio method

⇒ uncooked cups : water cups : cooked cups

⇒ 2 : $2\frac{1}{2}$ : $4\frac{1}{3}$

⇒ x : y : $6\frac{1}{2}$

- By using cross multiplication

∵ x ( $4\frac{1}{3}$ ) = 2 ( $6\frac{1}{2}$ )

∵ $4\frac{1}{3}$ = $\frac{13}{3}$

∵ $6\frac{1}{2}$ = $\frac{13}{2}$

∴ x ( $\frac{13}{3}$ ) = 2 ( $\frac{13}{2}$ )

∴ $\frac{13}{3}$ x = 13

- Divide both sides by $\frac{13}{3}$

∴ x = 3

∴ The number of the cups of uncooked rice is 3 cups

- By using cross multiplication

∵ y ( $4\frac{1}{3}$ ) = ( $2\frac{1}{2}$ )( $6\frac{1}{2}$ )

∵ $2\frac{1}{2}$ = $\frac{5}{2}$

∵ $6\frac{1}{2}$ = $\frac{13}{2}$

∵ $4\frac{1}{3}$ = $\frac{13}{3}$

∴ $\frac{13}{3}$ y = ( $\frac{5}{2}$ )( $\frac{13}{2}$ )

∴ $\frac{13}{3}$ y = $\frac{65}{4}$

- Divide both sides by $\frac{13}{3}$

∴ y = $3\frac{3}{4}$

∴ The number of the cups of water is $3\frac{3}{4}$ cups
