Make them both improper fractions.
77/10 - 19/5

Give them common denominators (multiply the second fraction by 2)
77/10 - 38/10

Subtract 
39/10 = 3 9/10

I need help with this ASAP.
Tomtit [17]

Answer:

Step 1 write the equation for perimeter (2L+2W =24)

Step 2 write the equation for area L x W = 32

Step 3 rewrite the equation of area so that one variable is on the right side L=32/W

Step 4 substitute L from step 3 into Equation 1 and simplify 2(32/W)+2W=24

Step 5 having found the width in step 4, use equation 3 to find the length

Step-by-step explanation:

<em>This is just added to show you how to solve but limit your answer to the answer above: rate brainliest please</em>

Area = L*W

Perimeter = 2(L+W)

So say L*W=32

and 2(L+W) = 24 which is 2L+2W =24

From area L=32/W

Then substitute it into perimeter

2(32/W)+2W=24 if you simplify this you get Width is 4 and 8

then length =32/W but W is 4 and 8 So L= 8 and 4

Meaning you have two options first rectangle is W=4 and L is 8, second triangle W=8 and Length=4

madreJ [45]
$140 dollars,
Using the equation (1/2)J/7=x. J=Jeremy's total money.7 because it was divided into 7 piles. Then, since 6 piles are blown away, we don't need to care about that for now. After that, you take 2 dollars and give the rest to Jeremy which is 8 dollars. You can create the equation x-2=8. Solve for x which is $10. Finally substitute that into the first equation to get (1/2)J=70. Multiply 2 to both sides to cancel out the (1/2) and the 70 by 2 to get Jeremy's total money which is $140

Answer:

\large \boxed{69^{\circ}}

Step-by-step explanation:  

                  Let y = m∠Y.

       Then 90 - y = the complement of ∠Y

     And 3(90 - y) = three times the complement of ∠Y

And 3(90 - y) + 6 = six more than three times the complement of ∠Y.

\begin{array}{rcll}y & = & 3(90 - y) + 6 & \\& = & 270 - 3y + 6 & \text{Distribuetd the 3}\\& = & 276 - 3y & \text{Simplified}\\4y &= & 276 & \text{Added 3y to each side}\\y & = & \mathbf{69} & \text{Divided each side by 4}\\\end{array}\\m \angle Y = \large \boxed{\mathbf{69^{\circ}}}
