Cross multiply

10/a = 15/30

10/a(a)(30) = 15/30(30)(a)

Simplify

1/a(a) = 1
15/30(30) = 15

10(30) = 15(a)

Simplify. Combine terms

300 = 15a

Isolate the a. Divide 15 from both sides

300/15 = 15a/15

a = 300/15

a = 20

A) a = 20 is your answer


hope this helps

Hello!

To solve this we will cross multiply the first numerator by the second denominator and then divide by the other value you have besides a, which in our case is 15.

10(30)=300

300/15=20

Therefore, A=20.

I hope this helps!

yanalaym [24]
We know there’s 660 boxes and each box called for 3 eggs, therefore:

660=3X

when divide both sides by 3 to isolate the x, which will tell us the amount of eggs used…

660/3 = 220

KATRIN_1 [288]

Answer:

$5,500

Step-by-step explanation:

Since Landen Company uses a single overhead rate of $100 per direct labor hour, the total amount allocated to the deluxe and basic chairs is given by the sum of the DLH used up for both products multiplied by the overhead rate:

A =(20+35)*\$100\\A=\$5,500

The total amount allocated to these products is $5,500.
