I think it's 25. don't @ me
1. −2x−4=20+6x
Step 1: Simplify both sides of the equation.
−2x−4=20+6x
−2x+−4=20+6x
−2x−4=6x+20
Step 2: Subtract 6x from both sides.
−2x−4−6x=6x+20−6x
−8x−4=20
Step 3: Add 4 to both sides.
−8x−4+4=20+4
−8x=24
Step 4: Divide both sides by -8.
−8x/−8=24/−8
x=−3
Answer:
x=−3
3. (x/4)*(4)=(9)*(4)
x=36
Answer:
x=36
4.
2(5x−1)=3x+5
Step 1: Simplify both sides of the equation.
2(5x−1)=3x+5
(2)(5x)+(2)(−1)=3x+5(Distribute)
10x+−2=3x+5
10x−2=3x+5
Step 2: Subtract 3x from both sides.
10x−2−3x=3x+5−3x
7x−2=5
Step 3: Add 2 to both sides.
7x−2+2=5+2
7x=7
Step 4: Divide both sides by 7.
7x/7=7/7
x=1
Answer:
x=1
5.
8−2(3x−4)+2x=5(x+6)+4
Step 1: Simplify both sides of the equation.
8−2(3x−4)+2x=5(x+6)+4
8+(−2)(3x)+(−2)(−4)+2x=(5)(x)+(5)(6)+4(Distribute)
8+−6x+8+2x=5x+30+4
(−6x+2x)+(8+8)=(5x)+(30+4)(Combine Like Terms)
−4x+16=5x+34
−4x+16=5x+34
Step 2: Subtract 5x from both sides.
−4x+16−5x=5x+34−5x
−9x+16=34
Step 3: Subtract 16 from both sides.
−9x+16−16=34−16
−9x=18
Step 4: Divide both sides by -9.
−9x/−9=18/−9
x=−2
Answer:
x=−2
<u>Answer:</u>$68.69
<u>Step-by-step explanation:</u>
Calculation of bill value
Cheeseburgers = 26.25
(8.75 x 3)
Fish Sandwich = 6.75
Pizza = 14.99
Sweet Tea
(4 x 2.09) = 8.36
Total of items = 56.35
Sales tax on food = 3.381
(56.35 x 6%)
Total bill value = 59.731
Calculation of tips
Bill value x 15%
=59.731 x 15%
Tips paid=8.95965
Calculation of meals cost
Total meal cost = Bill value + tips
=59.731+8.95965
=$68.69
Total meal cost is $68.69
Answer:
1, 4, 3, 2, 6, 5
Step-by-step explanation:
There is X pounds of butterscotch
There is Y pounds of peppermint
It costs $2.35 per pound of peppermint
It costs $2.15 per pound of butterscotch

It costs $22.00 to buy the whole mixture
Answer:
TS = 12.7
Step-by-step explanation:
From the question given above, the following data were obtained:
QR = 9
QP = 6
TU = 19
TS =?
Since the triangles are SIMILAR, then,
QR / TU = QP / TS
With the above equation, we can obtain the value of TS as follow:
QR = 9
QP = 6
TU = 19
TS =?
QR / TU = QP / TS
9 / 19 = 6 / TS
Cross multiply
9 × TS = 19 × 6
9 × TS = 114
Divide both side by 9
TS = 114 / 9
TS = 12.7
