Answer:
x = 60°
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Geometry</u>
- A box on an angle signifies a 90° angle
- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up equation</u>
x° + 90° + 30° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: x + 120 = 180
- Subtract 120 on both sides: x = 60°
Answer:
8!
Step-by-step explanation:
find numbers for school bus and car by multiplying percentages in decimal form 40% turns into .40 and 30 into .30
0.4x80 and 0.3x80 = 32 and 24. 32-24=8
Holassssssss ggfff bbcccc
That's already in gradient-intercept form, EXCEPT that we typically write such an equation with y positive.
So we'd geet y = -x - 1 (answer)
Note that "gradient" means "slope" here. The slope is -1 and the y-intercept is also -1.
Answer:
1. 
2. 
3. 
Step-by-step explanation:
1. The word "of" means "to multiply" so it would be 
which can also be written as 
then you plus 7
2. this would be 1/3 times in parenthesis, g+8, and then added to 3c
3. this would be 1/6 times m, then plus 9
