Alicia has 32 stickers. This is 4 times as many stickers as Benita has. How many stickers does Benita have?

1 answer:

8 0

Let's name the number of stickers Alicia has "a" and Benita as "b".

Then: a=32

a=4*b

We know this from the information above. Now we put it together:

32=4*b

we divide both sides by 4:

8=b

Benita has 8 stickers.

Answer:

784 in²

Step-by-step explanation:

Let the original side is x.

1 foot = 12 inches

New sides of a rectangle are:

x + 12 and x - 4

The area of rectangle is:

(x + 12)(x - 4) = 960

Solve for x:

x² + 8x - 48 = 960
x² + 2*4*x + 16 - 64 = 960
(x + 4)² = 1024
x + 4 = 32
x = 28

Area of the original blanket:

A = 28² = 784 in²

RSM QUESTION NEED HELP!!!!!! A pharmacist has a 13 % alcohol solution and another 18 % alcohol solution. How much of each must h

Luden [163]

Answer:

40 grams of 13% alcohol solution and 10 grams of 18% alcohol solution.

Step-by-step explanation:

13%(x) + 18%(50-x) = 14%*50g Multiply them all

0.13x + (9-0.18x) = 7

0.13x-0.18x + 9 = 7 Simplify the equation and subtract 0.13x from 0.18x

9-0.05x = 7 Add 0.05x to each side

9 = 7+0.05x Subtract 7 from both sides

0.05x = 2 Multiply each side by 100

5x = 200 Divide both sides by 5

x = 40

50 - 40 = 10

40 grams and 10 grams

Your welcome
