Sophia has $ 1912.03 left from last month's earnings

<u>Solution:</u>

Given, sophia earned $2,000 last month.  

She used 35 of her earnings to pay her bills.  

With the remaining money, she bought two shirts for $19.99 each and a pair of earrings for $12.99.  

We have to find how much money does Sophia have left from last month's earnings

Now, we know that,  

<em>Left money = earned money – used money</em>

= 2000 – (bills paid + 2 shirts cost + 1 pair of ear rings)

= 2000 – (35 + 2 x 19.99 + 12.99)

= 2000 – (35 + 39.98 + 12.99)

= 2000 – (87.97) = 1912.03

Hence, Sophia has $ 1912.03 left with her.

Point F is the midpoint of segment DE. DF = 2x+6 and DE = 2x+36. Find DE.
tensa zangetsu [6.8K]

Answer: It already tells you what DE= 60

Step-by-step explanation:

Since F is the midpoint of DE that means DF=FE

So create equation 2x+6+2x+6=4x+12

When DF and FE is added your answer should equal DE

So you write the equation 4x+12=2x+36 to find x and once x is found substitute your answer for x

4x+12(-12)=2x+36(-12) subtract 12 on both sides 36-12= 24

4x=2x+24 subtract 2x on both sides 4x-2x=2x

2x=24 divide 2 into both sides 24/2=12 x=12

4(12)+12=2(12)+36  

4x12=48+12=60   2x12=24+36=60
