Two mechanics worked on a car. The first mechanic charged $115 per hour, and the second mechanic charged $65 per hour. The mechanics
combined total of 15 hours, and together they charged a total of $1475. How long did each mechanic work?
Answer:
Here is another case where we have two unknowns (the number of hours each mechanic worked) so we'll need two equations to solve.
Let A = number of hours first mechanic worked (the one who charged $45/hour)
Let B = number of hours second mechanic worked (the one who charged $105/hour)
From the problem statement, we know that the two mechanics worked a combined 35 hours so the first equation is:
Equation 1: A hours + B hours = 35 hours
We also know that in total, the charge was $2475. So the second equation is:
Equation 2: (A hours x 45 dollars/hour) + (B hours x 105 dollars/hour) = 2475 dollars
So our two equations are:
1: A + B = 35
2: 45A + 105B = 2475
Multiply both sides of the first equation by -45 to get the following:
-45A - 45B = -1575
Now the two equations are:
1: -45A - 45B = -1575
2: 45A + 105B = 2475
Add them together and the "A" term drops out:
-45B + 105B = -1575 + 2475
or
60B = 900
Now divide both sides by 60:
B = 15
Now plug B = 15 into the first equation:
A + 15 = 35 thus A = 20
So Mechanic A (at $45/hour) worked 20 hours and Mechanic B (at $105/hour) worked 15 hours
Check: 20x45 + 15x105 = 900 + 1575 = 2475

Answer:
225 [tex]km^{2}[/tex]
Step-by-step explanation:
The scatter plot shows the average heights of children up to age 5.
Part A
Drag numbers to complete an equation for the trend line. Numbers may be used once, more than once, or not at all.
(22, 2.5, 18, 32, 4.5)
y = ?x + ?
Part B
Using the linear equation, predict the average height for a two-year old.
A. 15 inches
B. 22 inches
C. 31 inches
D. 35 inches
Answer:
(a) [tex]y = 4.5x + 22[/tex] -- The equation
(b) 31 inches
Step-by-step explanation:
Given
See attachment
Solving (a): The equation of the trend line.
We start by calculating the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (0,22)[/tex]
[tex](x_2,y_2) = (4,40)[/tex]
So, we have:
[tex]m = \frac{40 - 22}{4 - 0}[/tex]
[tex]m = \frac{18}{4}[/tex]
[tex]m = 4.5[/tex]
The equation is then calculated using:
[tex]y = m(x-x_1)+y_1[/tex]
Where:
[tex](x_1,y_1) = (0,22)[/tex]
[tex]m = 4.5[/tex]
[tex]y = 4.5(x - 0) + 22[/tex]
Open bracket
[tex]y = 4.5x - 0 + 22[/tex]
[tex]y = 4.5x + 22[/tex]
(b) The height of a 2 year old.
To do this, we substitute 2 for x in [tex]y = 4.5x + 22[/tex]
[tex]y = 4.5 * 2 + 22[/tex]
[tex]y = 9+ 22[/tex]
[tex]y = 31[/tex]
The prediction is 31 inches

27=15+n I can not get this one ether
Answer:
n= 12
Step-by-step explanation:
27=15+n
step 1. simplify
27=n+15
step 2. flip the equation n+15=27
step 3. subtract 15 from both sides
n+ 15 - 15 = 27 - 15 =
n=12
Answer:
12.
Step-by-step explanation:
We don't have the other number, so we must do the reverse operation, which is subtraction. So we have to subtract 27 from 15. 7-5 is 2, and 20-10 is 10. Add those together and you get 12.

Classify the polynomial according to its degree and number of terms.
9
constant monomial
sixth-degree monomial
linear binomial
sixth-degree binomial
Answer:
constant monomial
Step-by-step explanation:
The polynomial, 9, has 1 term and its degree is 0. Therefore, the polynomial is a constant monomial.
The given expression is a constant monomial. Therefore, option A is the correct answer.
What is the polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.
Here given expression is 9.
A constant monomial is a term with only a constant number. There is no variable in a constant monomial.
So, 9 is a constant monomial.
The given expression is a constant monomial. Therefore, option A is the correct answer.

Pleaseee helppp answer correctly !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!
Answer:
let the opposite angle of 44 be x
and let opposite angle of z be y
44+52 + x=180( by sum of all angle is 180°)
96+x=180
x= 180-96
x=84
y+x=180 ( linear pair angle)
y+84=180
y=180-84
y=96
now the y, z,40 are triangle.
y+z+40=180( by sum of all angle)
96+z+40=180
z+136=180
z=180-136
z=44

The perimeter of a rectangular field that measures 2 feet by 18 inches is _________ ft.
Answer:
7 ft
Step-by-step explanation:
As we know that the formula to find the perimeter of a rectangle is
P = 2 (l) + 2(w). With that being said, we can look at the question.
The answer should be given in terms of feet, so we will have to convert 18 inches to ft. In order to convert from inches to ft, you will have to divide by 12.
18 / 12 = 1.5ft
18 inches = 1.5 foot
Now we take the given values and put them into the formula to find the perimeter of the rectangular field.
2 (l) + 2(w) = 2 (2 ) + 2 (1.5) = 7ft
The perimeter of the rectangular field is 7ft.
