Megan uses 2/3 cup of almonds to make 4 cups of trail mix. Using this same proportion how many cups of almonds would Megan need
PIT_PIT [208]

Answer:

Megan needs 1 and 1/3 cup of almonds to make 9 cups pf trail mix.


Step-by-step explanation:

I'm not good with ratios and fractions so I drew an illustration.

I found out that 1/6 of almond cup is equivalent to 1 cup of trail mix.

So I add 2/3+2/3+1/6

I changed the denominator of 2/3 to 6 and divided 6 by 3 then multiply the answer by 2, then the product will be the numerator.

(6÷3) = 2 (2x2) =4

So, 4/6+4/6+1/6= 9/6

Simply the sum and it will be 1 and 1/3.

A computer cost £900. It is on sale for 25% off. You also need to pay 6% sales tax. What is the final price of the computer?
Vesna [10]

First we have to find 25% of 900 pounds (i hope that's the right currency). so 900 x .25 = 225

so we subtract 225 from 900 and get 675 pounds.

to find sales tax we have to find 6% of 675, so 675 x .06 = 40.50

675 + 40.50 = 715.5 pounds

Plzz hurry<br> 12/19(x-22)=38-6x-3
nadya68 [22]

Answer:

x = 929/126

Step-by-step explanation:

12/19(x-22)=38-6x-3

Combine like terms

12/19(x-22)=35-6x

Multiply each side by 19

19* 12/19(x-22)=19*(35-6x)

12( x-22) = 19*(35-6x)

Distribute

12x - 264 = 665 - 114x

Add 114x to each side

12x +114x - 264 = 665 - 114x+114x

126x -264 = 665

Add 264 to each side

126x-264+264 = 665+264

126x = 929

Divide each side by 126

126x/126 = 929/126

x = 929/126
