X+4b=72. If x=12, what’s the value of b?

2 answers:

8 0

So replace x as 12 now you rewrite the problem as 12+4b=72

Now you would have to move the constant towards the right side within it’s sign

4b=72-12

Now you subtract 72 by 12 which would give you 60

4b=60

Then you divide 4 by both sides

Therefore the answer is going to be b=15

b=15

To check do 12+4(15)=72

And that’s accurate

Solve the system of equations by elimination. 2x+8y=10 -4x-9y=-13 x = y =

Reptile [31]

So use cancelation
multiply first equation by 2
2x+8y=10
times 2
4x+16y=20
now add

4x+16y=20
-4x-9y=-13 +
0x+7y=7
7y=7
divide by 7
y=1

subsittue

2x+8y=10
2x+8(1)=10
2x+8=10
subtract 8 from both sides
2x=2
divide by 2
x=1

x=1
y=1

Select the correct answer. A company employs 48 people in various departments. The average annual salary of each employee is $25

Anna35 [415]

Answer:

A. $1,056,000 ≤ x ≤ $1,344,000

Step-by-step explanation:

The average annual salary of each of the 48 employees is given as;

$25,000

The total salary that the company pays to its employees annually is thus;

$25,000 * 48 = $1,200,000

Now, the total annual maximum variance of the employees salaries would be;

$3,000 * 48 = $144,000

The lower limit of the total salary that the company pays to its employees annually is calculated as;

$1,200,000 - $144,000 = $1056000

The upper limit of the total salary that the company pays to its employees annually is calculated as;

$1,200,000 + $144,000 = $1344000

Therefore, the range of the total salary that the company pays to its employees annually is;

$1,056,000 ≤ x ≤ $1,344,000
