Answer:
12 coins
Step-by-step explanation:
Points scored by collecting 7 coins = 581
Number of coins required to collect 996 points
Let Number of coins = c
7 coins = 581 points
c coins = 996 points
Cross multiply :
581 * c = 996 * 7
581c = 6972
Divide both sides by 581
581c / 581 = 6972 / 581
c = 12
Hence, number of coins required to collect 996 points is 12

7 + y = 5(2y – 1) + 3y
Answer:
y = 1
Step-by-step explanation:
Given
7 + y = 5(2y - 1) + 3y ← distribute and simplify right side
7 + y = 10y - 5 + 3y
7 + y = 13y - 5 ( subtract y from both sides )
7 = 12y - 5 ( add 5 to both sides )
12 = 12y ( divide both sides by 12 )
1 = y

Use any method to multiply (–14ab)(a + 3b – 4c).
Question 2 options:
A)
–14a2b – 42ab2 + 56c2
B)
14a2b + 42ab2 + 56abc
C)
–14a2b – 42ab2 + 56abc
D)
–14a2b – 42a2b2 + 56c
Answer:
-14 a^2 b - 42 a b^2 + 56 a b c C. is the answer
Step-by-step explanation:
Expand the following:
-14 a b (a + 3 b - 4 c)
Hint: | Distribute -14 a b over a + 3 b - 4 c.
-14 a b (a + 3 b - 4 c) = -14 a b a - 14 a b×3 b - 14 a b (-4 c):
-14 a b a - 14×3 a b b - 14 (-4) a b c
Hint: | Combine products of like terms.
-14 a b a = -14 a^2 b:
-14 a^2 b - 14×3 a b b - 14 (-4) a b c
Hint: | Combine products of like terms.
-14 a b×3 b = -14 a b^2×3:
-14 a^2 b + -14×3 a b^2 - 14 (-4) a b c
Hint: | Multiply -14 and 3 together.
-14×3 = -42:
-14 a^2 b + -42 a b^2 - 14 (-4) a b c
Hint: | Multiply -14 and -4 together.
-14 (-4) = 56:
Answer: -14 a^2 b - 42 a b^2 + 56 a b c

Hours it takes Elena and Jada to meet: (2 points)
Answer:
The hours it takes Elena to meet Jada = 4 hours
Step-by-step explanation:
The distance between Elena and Jada = 32 miles
The speed with which Elena runs = 6 miles per hour
The speed with which Jada walks = 2 miles per hour
Let t, represent the time it takes until Elena and Jada meets, we have;
Distance = Speed × Time
The total distance covered by both Elena and Jada before they meet = The distance between them = 32 miles
The distance covered by Elena before meeting Jada = Elena's speed × The time that elapsed for them to meet
∴ The distance covered by Elena before meeting Jada = 6 mph × t
The distance covered by Jada before meeting Elena = Jada's speed × The time that elapsed for them to meet
∴ The distance covered by Jada before meeting Elena = 2 mph × t
The total distance covered by both Elena and Jada before they meet = The distance covered by Elena before meeting Jada + The distance covered by Jada before meeting Elena = 32 miles
∴ The total distance covered by both Elena and Jada before they meet = 6 mph × t + 2 mph × t = 32 miles
t × (6 mph + 2 mph) = 32 miles
t × 8 mph = t × 8 miles/hour = 32 miles
t = 32 miles/(8 miles/hour) = 4 hours
The time it takes until Elena and Jada meets = t = 4 hours

Timmy wants to buy a scooter and the price was $150. When he goes to the store a
second time, he found that the price was marked down by 15%. Then when he gets to the
register the cashier tells him today only he gets an additional 10% off the sales price. What is
the final cost of the scooter including the discounts?
Answer:
112.5
Step-by-step explanation:
total discount: 25%
Answer:
Step-by-step explanation:
150*15% off =22.50 off total 127.50. Then he gets the 10% off 127.50*10%= 12.75 off total cost $114.75
It may look like 25% off at once, but most stores will do the discounts separately so they don't lose too much money.

Solve for x.
−x − 4( 1−x)>1
x −1
x>5/3
x<−1
Answer: x> 5/3
Step-by-step explanation: Let's solve your inequality step-by-step.
−x−4(1−x)>1
Step 1: Simplify both sides of the inequality.
3x−4>1
Step 2: Add 4 to both sides.
3x−4+4>1+4
3x>5
Step 3: Divide both sides by 3.
3x /3 > 5 /3
x> 5 /3
