Answer:
2 possible full shifts
Step-by-step explanation:
Given
Total number of hours per week= 24hours
Number of hours worked so far= 7 hours
Number of hours remaining =24-7 = 17hours
If each shift remaining are 6hours long then
1shift = 6hrs
x = 17 hours
Cross multiply
6x = 17
x = 17/6
x = 2.83
Hence she can only work 2 possible full shifts
-x - 163 = 12x + 84
Answer:
X = -19
Step-by-step explanation:
Add x to both sides to get rid of -x
-163 = 13x + 84
subtract 84 from both sides
-247 = 13x
divide by 13
x = -19

Marcus looked out in the audience and saw 40% of the chairs were filled. There were 42 people sitting in the chairs. Enter the total number of chairs in the audience.
Answer:
I say it is 16.8
Step-by-step explanation:
40 x 42
100
= 16.8
The total number of chairs in the audience is 105.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, Marcus looked out into the audience and saw 40% of the chairs were filled and 42 people are sitting in the chairs.
Let, 'x' be the total number of chairs.
Therefore, 40% of 'x' is 42 which can be numerically expressed as,
(40/100)×x = 42.
0.4x = 42.
x = 42/0.4.
x = 105.
So, The total number of chairs in the audience is 105.

A jacket is on sale for 40% off .The sale price is $90.00.What is the original amount of the jacket
The original amount of the jacket is $150.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
A jacket is on sale for 40% off.
The sale price is $90.00.
let the Original price be x.
So, x - 40% of x = 90
x - 40x/100 = 90
x- 0.4x= 90
0.6x= 90
x= 90/0.6
x= 900/6
x= 150
Hence, the Original Price is $150.

Pythagorean theorem to find the side of 16 20
Answer: 12
Step-by-step explanation:
Although you have not included which value is the hypotenuse or if they are legs, I will assume the hypotenuse is 20, due to the triangle appearing to be a multiple of the standard 3-4-5 triangle.
The pythagorean theorem is a^2+b^2=c^2, where a and b are the legs and c is the hypotenuse. Thus, plug in the values to get:
[tex]16^2+b^2=20^2[/tex]
[tex]256+b^2=400[/tex]

It is given that y varies inversely as x varies. If x = 8 and y=6, what is the value of y when x = 4?
Answer:
y = 12
Step-by-step explanation:
set up equation for 'y varies inversely with x': y = k/x
where 'k' is the constant of variation
8 = k/6
therefore, k = 48
value of y when x = 4: y = 48/4; therefore, y = 12
Thevalue of y when x is 4 is 12
If y varies inversely as x, this is expressed as;
y = k/xk is the variation constantIf x = 8 and y=6
k = xy
k = 8 * 6
k = 48
To get the value of y when x = 4
y = k/x
y = 48/4
y = 12
Hence the value of y when x is 4 is 12

A. (0, -3)
B. (0,3)
C. (1,-4)
D. (3,0)
Answer:
The points (3, 0) and (0, -3) would be the two solutions.
Hence, options A and D are correct.
Step-by-step explanation:
We know that when the system of equations meets at a point on a coordinate plane, that point or points will be the required set of solutions.
The point where the system of equations meets is called the point of intersection.
If we closely observe, the graph indicates that the graph of two equations meets at the following two points:
at x = 3 and y = 0at x = 0, y = -3Therefore, the points (3, 0) and (0, -3) would be the two solutions.
Hence, options A and D are correct.
