What is the solution to the equation? a+5 2/3=9

Mathematics
1 answer:
Firlakuza [10]3 years ago
8 0

Answer:

a=8+1/2

Step-by-step explanation:

We move all terms to the left:

(a+5)2/3-(9)=0

We multiply all the terms by the denominator

(a+5)2-9*3=0

We add all the numbers together, and all the variables

(a+5)2-27=0

We multiply parentheses

2a+10-27=0

We add all the numbers together, and all the variables

2a-17=0

We move all terms containing a to the left, all other terms to the right

2a=17

a=17/2

a=8+1/2

Find the points at which the graph of the equation -4y=15-5x crossed the x- axis and the y - axis.
Lynna [10]

Answer:

see explanation

Step-by-step explanation:

Where the graph crosses the x- axis the y- coordinate is zero.

Let y = 0 in the equation and solve for x

- 4(0) = 15 - 5x, that is

15 - 5x = 0 ( subtract 15 from both sides )

- 5x = - 15 ( divide both sides by - 5 )

x = 3 ← x- intercept ⇒ (3, 0 )

Where the graph crosses the y- axis the x- coordinate is zero.

Let x = 0 in the equation and solve for y

- 4y = 15 - 5(0), that is

- 4y = 15 ( divide both sides by - 4 )

y = - \frac{15}{4} ← y- intercept ⇒ (0, - \frac{15}{4})

gayaneshka [121]

Answer:

a) Real range of employees hired by each organization surveyed = 56

b) The cumulative percent of "new" employees with the lowest tenure =        30%

Step-by-step explanation:

a) Note: To get the real range of employees hired by each organization, you would do a head count from 34 to 89 employees. This means that this can be done mathematically by finding the difference between 34 and 89 and add the 1 to ensure that "34" is included.

Real range of employees hired by each organization surveyed = (89 - 34) + 1

Real range of employees hired by each organization surveyed = 56

b) It is clearly stated in the question that  the "new" employee status was mostly reserved for the 30% of employees in the organization with the lowest tenure.

Therefore, the cumulative percent of "new" employees with the lowest tenure = 30%
