Answer:
x = 1/3
Step-by-step explanation:
Step 1: Write equation
8x + 11 = 14 - 1x
Step 2: Solve for <em>x</em>
- Simplify: 8x + 11 = 14 - x
- Add x to both sides: 9x + 11 = 14
- Subtract 11 on both sides: 9x = 3
- Divide both sides by 9: x = 3/9
- Simplify: x = 1/3
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
8(1/3) + 11 = 14 - 1(1/3)
8/3 + 11 = 14 - 1/3
41/3 = 41/3
Answer:
Step-by-step explanation:
slant height is given. Using Pythagorean theorem to find height.
h² = 10² - 5²
= 100 - 25
h² = 75
h = √75
h = 8.66 cm
Volume =(1/3)πr²h

= 226.62 cubic cm
There are 5280 ft in a mile. 55*5280=290400. So the car is travelling 290,400 ft/hour
Y = mx + c, where m = slope= -8, c = y intercept = 4.
y = -8x + 4
The equation is <span>y = -8x + 4</span>
66. First, you have to take the 4

and change it from a compound fraction so you can multiply so it becomes


67. First, take 4

and it becomes

. 9 becomes

in order to work with the fractions.
