<h3><u>The value of x is 19.</u></h3><h3><u>The value of y is 4.</u></h3>
x = 3 + 4y
x + y = 23
Because we have a value for x we can plug it directly into the second equation.
3 + 4y + y = 23
Subtract 3 from both sides.
4y + y = 20
Combine like terms.
5y = 20
Divide both sides by 5.
y = 4
Plug this value for x back into the original equation.
x = 3 + 4(4)
x = 3 + 16
x = 19
Answer:
x=-9/10
Step-by-step explanation:
2x+8x+16=7
Step 1: Simplify both sides of the equation.
2x+8x+16=7
(2x+8x)+(16)=7(Combine Like Terms)
10x+16=7
10x+16=7
Step 2: Subtract 16 from both sides.
10x+16−16=7−16
10x=−9
Step 3: Divide both sides by 10.
10x/10
=
−9/10
x=-9/10

Answer:
median: 86.5 <em>2)</em> 50.9% <em>3) </em>36.18 or 36.2 rounded
Step-by-step explanation:
To find the median, you have to order all of the numbers in a sequence from smallest to largest, and pick the number in the middle.
You'd order this sequence:
70, 77, 79, 84, 86, 87, 87, 91, 91, 91
The number in the middle is:
between 86, 87 the amount of numbers in the sequence is an even number.
The number between these two numbers, however, is <em>86.5</em>
<em>2)</em>
140/275 = .509 or 50.9%
3)
.18 x 201 = 36.18 or 36.2
A graphing calculator can be helpful for these.
A) Since neither inequality includes the "or equal to" case, the boundary line for the solution set is a dashed line. For the first inequality, the shading is above the line; for the second, the shading is below the line. The solution set is points to the right of perpendicular lines with slope -2 and +1/2 through point (2, -1).
B) The point -2, 3 satisfies, neither inequality.
