Answer:
x = -31
Step-by-step explanation:
2(x-5) = 3(x+7) 1. Use distributive property
2x - 10 = 3x + 21 2. Add 10 on both sides
2x = 3x + 31 3. Subtract 3x on both sides
-x = 31 4. Divide by -1
x = -31

You and 3 friends are going to the fair. You have a coupon that will save your group $20. If the total bill to get into the fair was $100, how much does one regular priced ticket to the fair cost?
Equation:
Answer:
Answers
Answer:
one regular ticket costs $30
Step-by-step explanation:
The total number of people = 4
Without the $20 coupon, the total cost would have been =100+20 = $120
Assume the price of one regular ticket is x;
4x = 120
Divide both sides by 4 to solve for x
x = 120/4
x = 30
Therefore, one regular ticket costs $30
Answer:
$30
Step-by-step explanation:
Since you pay 100 after discount, you add the 20 dollar discount to the 100 ($120)
Then since there are 4 of you in total, (you+ 3 friends), you divide by 4.
And Voila, your answer is $30 per person.

Answers
Answer:
30.4%
1000 at £1.10
1000 x 1.10 = £1100
35% of 1000 is given away
1000 - 35% = 1000 - 350 = 650 left
35% of £1100 = £385, subtract to get £715 pounds worth of pins left
650 are left, with 385 pounds lost
60% of 650 = 390 pins sold at £3 each
40% of 650 = 260 sold at £5 for 2
3 x 390 = £1170 made from the first lot
260/2 = 130 x 5 = £650 made from the second lot
£1170 + £650 = £1820 from sales
Sales - cost to make - losses (giveaways) = profit value
1820 - 1100 - 385 = 335 pounds of profit
To find the gross profit margin, we take the profit, and find what percentage of the production cost it is.
335 is about 30.45% of 1100
30.45%, which is 30.4% to 1 decimal place.

Which model shows ^3√64 = 4 ?
Answers
Answer:
if we carefully observe, left-bottom model contains 4 units on each side of the cube.
Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].
The correct model is attached below.
Step-by-step explanation:
Given the expression
[tex]\sqrt[3]{64}=4[/tex]
Cubing both sides
64 = 4³
Thus, the cube will have 4 units on each side.
Now, if we carefully observe, left-bottom model contains 4 units on each side of the cube.
Therefore, we conclude that left-bottom model represents the [tex]\sqrt[3]{64}=4[/tex].
The correct model is attached below.
