32°+81°=113°
For a complete triangle to form it needs to be 180°. So all you do is subtract 180° by the sum of 32° and 81°.
180°-113°=67°
The answer is 67°
First, let's simplify the expression: 7 - 5 + 3x - 1 ⇒ 3x + 1 <em>(slope=3, y-intercept = 1)</em>
Next, let's understand what they are asking for:
<u>no solutions</u> means same slope but different y-intercepts
Answer: 3x + _______ (the blank can be anything except 1)
<u>one solution</u> means different slopes
Answer: ________x + _______ (the first blank can be anything except 3, the second blank can be anything)
<u>infinitely many solutions</u> means same slope and same y-intercept
Answer: 3x + 1
Answer:
Sea level is 0 meters. A cliff by the ocean is 12 meters above sea level. Around that area, the seafloor is 8 meters below sea level. How many meters is the top of the cliff to the seafloor?
How to solve:
8 below zero is -8
The expression 12 - (-8) is the same as the expression 12 + 8
12 + 8 = 20
20 meters
The value of x is 3
<h3>How to solve for x?</h3>
The given parameters are:
Length = 10cm
width = 2cm
Height = x
The surface area is calculated as;
Area = 2 *(lw + lh + wh)
So, we have:
2 * (10 * 2 + 2x + 10x) = 112
Evaluate the like terms and divide by 2
20 + 12x = 56
Subtract 20 from both sides
12x = 36
Divide by 12
x = 3
hence, the value of x is 3
