How many solutions does 5(x+9)=5x+45 have

Scilla [17]3 years ago

Answer:

Simplifying

5(x + 9) = 5x + 45

Reorder the terms:

5(9 + x) = 5x + 45

(9 * 5 + x * 5) = 5x + 45

(45 + 5x) = 5x + 45

Reorder the terms:

45 + 5x = 45 + 5x

Add '-45' to each side of the equation.

45 + -45 + 5x = 45 + -45 + 5x

Combine like terms: 45 + -45 = 0

0 + 5x = 45 + -45 + 5x

5x = 45 + -45 + 5x

Combine like terms: 45 + -45 = 0

5x = 0 + 5x

5x = 5x

Add '-5x' to each side of the equation.

5x + -5x = 5x + -5x

Combine like terms: 5x + -5x = 0

0 = 5x + -5x

Combine like terms: 5x + -5x = 0

0 = 0

Solving

0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions

Can someone please help me with this problem? A fastpitch softball player signs a six year contract. Her agent expects that she
Luba_88 [7]

Answer:

The question is not complete, below is the complete question:

A fastpitch softball player signs a six-year contract. Her agent expects that she will earn $1,000,000 over the next six years. If the agent is right, how many bonus payments, on average, should the pitcher expect each year? Explain

Yearly Salary: $20.000. Bonus for each game that attracts 100+ fans: $8.000.

Answer:

on average, the pitcher expects to earn 18.3 bonuses per year

Step-by-step explanation:

Total amount earned over the next 6 years = $1,000,000

salary per year = $20,000

salary for the next 6 years = 20,000 × 6 = $120,000

Next, let us calculate the amount earned from bonuses:

Total amount earned = amount earned from salaries + amount earned from bonuses

$1,000,000 = 120,000 + Amount earned from bonuses

Amount earned from bonuses = 1,000,000 - 120,000

Amount earned from bonuses = $880,000

Total bonus amount earned over six years = $880,000

Amount of bonus earned per game = $8,000

Number of bonuses received over the next 6 years = (Total bonus earned over six years) ÷ (Amount of bonus earned per game)

Number of bonus received over the next 6 years = 880,000 ÷ 8,000

Number of bonus received over the next 6 years = 110 bonuses

6 years = 110 bonuses

1 year = 110 ÷ 6 = 18.33 bonuses

on average, the pitcher expects to earn 18.3 bonuses per year

There a five questions. PLEASE ANSWER THEM ALL CORRECTLY TO GET BRAINLIEST AND FULL POINTS. PLEASE HURRY UP 30 PTSSSS
Ksenya-84 [330]

Answer:

math

Step-by-step explanation:

1. First we divide 3/4m by 3/4 and -12 by 3/4. When -12 is divided by 3/4, the solution is m>-9, which is answer choice number 3.

2. Again, all you have to do is divide both sides by 1.2. ((4 1/2) / 1.2 = 3.75) which is answer 1.

3.

1. Since we have to solve this inequality, we need to divide both sides by -4. (8.4 / -4 = -2.1). Because we divided by a negative, we need to flip the sign, making the inequality x<-2.1 and <------------0

2. Same as above, except we don't flip the sign. ((3/4) / (3/5) = 1 1/4). The solution is z>1 1/4 and 0------------>.

3. Again, the same. (-16 / -4 = 4) Since we divided by a negative, we flip the sign. The solution is 4≤p and 0-----------> with closed circle.

A aluminum bar 3 feet long weighs 12 pounds. What is the weight of a similar bar that is 3 feet 4 inches long?
amm1812

Answer:

13 1/3 pounds.

Step-by-step explanation:

3 feet = 36 inches

3 feet 4 inches = 36 + 4 = 40 inches

By proportion the weight of the larger  bar = 12 * 40/36

= 12 * 10/9

= 120/9

= 13 1/3 pounds.
