Lisa says that the indicated angles cannot have the same measure. Marita disagrees and says she can prove that they can have the

AlexFokin [52]

I agree with Marita, that the angles could have the same measure. This can be proven if you set the two amounts equal and solve for x.

9x - 25 + x = x + 50 + 2x - 12

To begin, we should combine like terms on both sides of the equation to start simplifying the equation.

10x - 25 = 3x + 38

Next, we should subtract 3x from both sides and add 25 to both sides to get the variable x alone on the left side of the equation.

7x = 63

Finally, we should divide both sides by 7, to get rid of the coefficient of x.

x = 9

If you plug in 9 for x in our first equation, you get that both of the angle measurements equal 65 degrees. This means that Marita is correct, because if x = 9, then the angles would have the same measure.

Fuji apples cost $3.00 per pound, and Golden Delicious apples cost $2.00 per pound. A childcare center purchases 30 pounds of a

konstantin123 [22]

Answer:

$3(30-g)$

Step-by-step explanation:

A following table titled Apples showing Pounds, Cost per Pound and Total.

$\begin{array}{cccc}\text{Apples}&\text{Pounds}&\text{Cost per Pound}&\text{Total}\\ \\\text{Fuji}&30-g&3&x\\ \\\text{Golden delicious}&g&2&\\ \\\text{Total}&30&&80\end{array}$

This means that

1 pound of Fuji apples costs $3

(30 - g) pounds of Fuji apples cost $\$(30-g)\cdot 3$

Hence, the total is

$x=3(30-g)$

Fudgin [204]

Answer:

a) 1:3

b) 9:225,000

Step-by-step explanation:

A)

1 hour is equal to 60 minutes. Written as a fraction it would look like

$\frac{20}{60}$ which would be equal to $\frac{1}{3}$ , or $1:3$

B)

Just multiply both sides of the ratio by 9, you will get $9:225,000$
