Fred's age is 82.
Amanda's age is 27.
Catherine's age is 14.
Blake's age is 12.
The equation that represents Fred's age is: 1 + 3x =
Where x is Amanda's age
Fred and Amanda's age : 109 = 1 + 3x + x
4x + 1 = 109
4x = 109 - 1
4x = 108
x = 108 / 4
x = 27
Fred's age = 1 + (3 x 27) = 82
The equation that represents Blake's age is: b = 2c - 16
Where: b = Blake's age
c = Catherine's age = 2 + b
b = 2(2 + b) - 16
b = 4 + 2b - 16
16 - 4 = 2b - b
12 = b
Catherine's age = 12 + 2 = 14

A certain television is advertised as a 10-inch TV (the diagonal length). If the width of
the TV is 6 inches, how many inches tall is the TV?
Answer:
8 in
Step-by-step explanation:
Given data
DIagonal= 10 in
Width= 6 in
`Height=???
We know that the expression that can be used to find the missing dimension is given as
d^2= w^2+h^2
substitute
10^2=6^2+h^2
100= 36+h^2
100-36= h^2
64= h^2
h= √64
h= 8 in
Hence the height is 8 in
An angle measures 27.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
Supplementary angles have a sum of 180 degrees.
a+a-27.2=180
2a-27.2=180
2a=207.2
a=103.6, and since b=a-27.2
b=76.4
So one angle is 103.6 degrees and the other is 76.4 degrees.

Answer:
11
Step-by-step explanation:
17+9+11+7 divided by 4
because the mean= sum of the terms divided by the number of terms
the sum= 17+9+11+7=44
the number of terms= 4
44 divided by 4= 11
Answer:
(17+9+11+7) / 4 mean is an average
it is equal to the sum of the elements divided by the number of elements
the sum is 44
the number of elements is 4
the mean is the average= 44/4=11

lines s and t intersect so that the measure of angle 1 is 85 degrees. if angle 2 is supplement to angle 1 what is the measure of angle 2
Answer:
95 degrees
Step-by-step explanation:
The sum of two supplementary angles is 180 degrees
Given
angle 1 = 85 degrees
If angle 2 is the supplement of angle 1, then
<1 + <2 = 180
85 + <2 = 180
<2 = 180 - 85
<2 = 95degrees
Hence the measure of angle 2 is 95 degrees

The length of a rectangle is (3x - 1) and its width is ( 2x + 5). What is the area of the rectangle?
Answer:
3x^2 + 13x - 5
Step-by-step explanation:
To find the area, you multiply the length by width. So its is (3x - 1) * (2x + 5)
Then distribute. (3x * 2x) + (3x *5) + (-1 *2x) + (-1 * 5)
So 3x^2 + 15x -2x -5
Final Answer: 3x^2 + 13x - 5

Answer:
x = 9
Step-by-step explanation:
Because the angles are vertical angles their measures are congruent so make them equal to each other:
3x -8 = 2x +1 subtract 2x from both sides
-2x -2x
x -8 = 1 add 8 to both sides
+8 +8
x = 9
