8 0

Answer: 45

Step-by-step explanation:

I don't know if you mean the "x" as multiplication or as a variable, but I will assume it means multiplication.

First:

Calculate what is inside the brackets ( [ ] )

4x(3+5)+8

=4x8+8

=32+8

=40

Next:

15-5x2+40

=15-10+40

=5+40

=45

Vaselesa [24]

Answer:

The barge can carry up to 94 railroad cars.

Step-by-step explanation:

Create an inequality to represent the weight of the barge to the max weight.

24 + 4r ≤ 400

Solve for r:

4r ≤ 400 - 24

4r ≤ 376

4r ≤ 376/4

r ≤ 94

If a person starts investing $100 per month starting at age 21, and that money earns a 5% return every year, how much will this
aalyn [17]

The formula for calculating compound interest with yearly contributions is:

Balance = X*(1 + Y)^n + Z((1 + Y)^(n + 1) - (1 + Y)/Y)

where the balance is the money earned after n years invested

Y is the interest rate as a fraction

Z is the yearly contribution

X is the starting investment

Therefore the calculation for this example is:

Balance = 1200*(1 + 0.05)^48 + 1200((1.05)^49 - (1.05)/05)

= $249,393.5

You need to rent a bowling lane. On Friday nights, you have two options. Option A is a $20 lane rental plus $3 per game. Option
ExtremeBDS [4]

For 5 games, the cost will be equal for each option.

Step-by-step explanation:

Given,

Lane rental of offer A = $20

Per game charges = $3

Let,

x be the number of games.

A(x) = 3x + 20

Lane rental is $35 for maximum 10 games.

B(x) = 35

For the cost to be same;

A(x) = B(x)

3x+20=35\\3x=35-20\\3x=15

Dividing both sides by 3

\frac{3x}{3}=\frac{15}{3}\\x=5

For 5 games, the cost will be equal for each option.
