Step-by-step explanation:
Givens
b1 = 13
b2 = ?
h = 6
Area = 120
Formula
Area = (b1 + b2) * h/2 Multiply by 2
2Area = (b1 + b2)*h Divide by h
2Area/h = b1 + b2 Subtract b1 from both sides
2Area/h - b1 = b2
Solution
2*120 / 6 - 13 = b2
40 - 13 = b2
b2 = 27

Eliminate the y in the following system of equations. What is the result when you add the two equations?
3x - 2y = 8
x + y = 6
Answer:
X=4
Step-by-step explanation:
3x-2y=8
x+y=6
multiply second equation by 2 so you can eliminate y
2(x+y)=2(6)
2x+2y=12
now add two equations together
first equation: 3x-2y=8
modified second equation 2x+2y=12
added together eliminates y. 5x+0=20
X=4

Amelia can spend no more than $150 to rent a car for a day trip. A rental car costs $35 per day plus $0.75 per mile.What is the maximum number of miles that Amelia can drive?
Answer:
If she is only driving the car for a day, she will only have to pay the one-time fee of $35 per day
35+0.75x=150
x being the number of miles
x= 153.3 miles

Step-by-step explanation:
inside of a triangle is 180 degrees
[tex]180=90+5x+2+4x-11\\180=5x+4x+90+2-11\\180=9x+81\\180-81=9x+81-81\\99=9x\\99/9=9x/9\\11=x[/tex]
now that we have our x we can find the angles
[tex]M=90\\\\K=5(11)+2\\K=57\\\\\\L=4(11)-11\\L=33[/tex]

Answer:
5.3
Step-by-step explanation:
The Pythagorean theorem applies. The square of the hypotenuse is equal to the sum of the squares of the other two sides.
8² = x² + 6²
64 = x² +36
28 = x²
√28 = x ≈ 5.3
The missing measure is 5.3.

Comment on the question
The triangle isn't marked, but we must assume it is a right triangle. If it is not a right triangle, we cannot find the missing measure.

Answer:
34.8 to 1 dp
Step-by-step explanation:
18/2 = 9
Area of rectangle 18 X 9 = 162 cm^2
diameter of each circle 9
radius = 4.5
Area of a circle = πr^2
π X 4.5^2 = 63.6172512
63.6172512 X 2 (there are 2 circles) = 127.234502
162 - 127.234502 = 34.7654975

Simple math
solve the simultaneous equation
2x + 4y=1
3x - 5y=7
Answer:
x = 3/2 or 1.5.
y = -1/2 or -0.5.
Step-by-step explanation:
Solve for one equation, one variable.
2x + 4y = 1
subtrract 4y from both sides.
2x = 1 - 4y
divide by 2 to get x by itself.
x = 1/2 - 2y
Now that we have this, we can put it into the other equation.
3x - 5y = 7
Substitute variable.
3(1/2 - 2y) - 5y = 7
Distribute the 3.
1.5 - 6y - 5y = 7
Combine terms.
-11y + 1.5 = 7
Subtract by 1.5.
-11y = 5.5
Divide by -11.
y = -1/2, or -0.5.
Now we can find x. Substitute this into the initial equation.
2x + 4y = 1
Substitute variable.
2x + 4(-1/2) = 1
Multiply.
2x + (-2) = 1
Simplify.
2x - 2 = 1
Add 2 to both sides.
2x = 3
Divide by 2.
x = 3/2, or 1.5.
x = 3/2 or 1.5.
y = -1/2 or -0.5.
