The total measure of angles in a triangle is 180°.
3x° + 2x° + 4x° = 180°
9x° = 180°
x° = 180° ÷ 9
x° = 20
Our 3 angles are:
3(20) = 60°
2(20) = 40°
4(20) = 80°
Done.
Answer:
Step-by-step explanation:
3x+2x+4x=180
9x=180
x=180/9=20
3x=3×20=60°
2x=2×20=40°
4x=4×20=80°

A computer has the shape of a rectangular solid. Find the volume of the computer, with
dimensions of 5 inches by 5 inches by 5.1 inches.
Answer:
V = 127.5in^3
Step-by-step explanation:
The volume of a rectangular prism is:
Volume = length x width x height
Therefore, in this equation it would look like this:
Volume = (5) x (5) x (5.1)
Volume = 127.5in^3

The maximum amount to donate to the summer camp fund is $2,250.
2. The equation that shows the maximum amount to donate is y = 4.5x.
What is an equation?An equation is a mathematical statement that two values are equal.
Using an equation, two mathematical expressions are stated to have equivalent values.
Equations are expressed using the equation symbol (=).
Data and Calculations:The expected number of theater goers = 500 persons
Admission charge per person = $10
Movie Theater's rental fee = $5.50
Ticket fee = $4.50 ($10 - $5.50)
Let y be the maximum amount to donate to the summer camp fund
Let x be = 500
y = (10 - 5.50)x
y = 4.5x
The required equation for the maximum amount to donate is y = 4.5x
y = 4.5 x 500
y = 2,250
Thus, the maximum amount to donate to the summer camp fund is $2,250.

Evaluate the expression for y= -1 -13y-16
Answer: y = -17/14
Step-by-step explanation:
y = -1 -13y - 16
First we must isolate the variable:
y+13y = -1 - 16
Next we must add like terms:
14y = -17
Finally, divide 14 on both sides:
14y/14= -17/14
Answer: y = -17/14

Each of the equal sides of an isosceles triangle is 5 times the third side. The perimeter of the triangle is 121 inches. Find the sides of the triangle.
Answer: The small side is 11, and the other two are 55, 55,
Step-by-step explanation:
So the perimeter adds up to 121 inches.
we know that two of the sides are 5x the 3rd side while being congruent.
11 times 5=55. 55 times 2=110. 110+11=121
Answer:
The third side is 11 inches
the 2 equal sides are 55 inches each side.
Step-by-step explanation:
X + 2(5x) = 121
x + 10x = 121
11x = 121
x = 121/11
x = 11

A first number plus twice a second number is 3. Twice the first number plus the second totals 21 . Find the numbers.
Answer:
x = 13
y = -5
Step-by-step explanation:
Let x = the first number
Let y = the second number
x + 2y = 3 2x + y = 21
You have two unknowns, so you need to equations to solve.
Solve the first equation for x:
x + 2y = 3
x = -2y + 3 Substitute this in for x in the second equation.
2x + y = 21
2(-2y + 3) + y = 21 Distribute the 2
-4y + 6 +y = 21 combine the y's
-3y = 15 Divide both sides by -3
y = -5
Plug -5 back in for either equation
x + 2y = 3
x + 2(-5) = 3
x -10 =3
x = 13
