Note: This means to multiply 2 with the numbers inside the parentheses.

2 * 3x = 6x

2 * 4y = 8y

Our answer would be 6x +8y

Alladin's Amusement Park has a popular roller coaster ride. There are 2 trains. Each train has 7 cars. Each car holds 16 people.

Nataly [62]

Answer:

224

Step-by-step explanation:

Number of trains in the roller coaster = 2

Number cars in each train = 7

Total number of cars = Number of trains $\times$ Number of cars in each train = $7\times 2$ = 14

Number of people in each car = 16

Total number of people in 14 cars = Number of people in one car $\times$ Number of cars = 16 $\times$ 14 = 224

i.e.

Total number of people in the roller coaster in one run = 224

Number of runs made by each train in one hour = 10

Therefore, Total number of people that can ride the roller coaster in one hour can be found by multiplying the number of runs with total number of people in the roller coaster in one run.

224 $\times$ 10 = <em>2240</em>

1. A geometric sequence has a common ratio. You can find the ratio by dividing every number by its previous one. If it is consistent, then the series is geometric.
a: 8/1=8, 27/8=3.375
b: (-3/2)/3=-1/2, (3/4)/(-3/2)=-1/2
c. 7/4=1.75, 10/7=1.429
d. 20/25=0.8, 14/20=0.7

Choice b is the only one that has a common ratio, so it is a geometric series.

2. Every term is multiplied by 1/3, so the common ratio is 1/3. d is the answer.

mark and heather starr are celebrating their 25th anniversary by having a reception at local reception hall. they have budget 45

Lera25 [3.4K]

Answer:

Step-by-step explanation:

The $50 cleanup fee is a "fixed cost."

The "$30 per-person fee is a "variable cost." That is, it varies with the number of people.

"within" means "less than or equal to"

Cost = $50 + $30x [where x = number of people]

Cost ≤ $4500 ["stay within their budget"]

$50 + $30x ≤ $4500 [substitute for cost]

$30x ≤ $4450 [subtract $50 from both sides retains sense of inequality]

x ≤ 148.3333 [divide by +$30 retains sense of inequality]

Mark and Heather may invite up to 148 guests.

[note: to be "≤," always truncate, never round up]

Check:

148 people for $30 each + $50 is $4440+$50 = $4490.

One more person makes it $4520 -- that is too much.

There we go, my bad
