- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up Equation</u>
(7x - 1) + 80 + (6x - 3) = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 13x + 76 = 180
- Isolate <em>x</em> term: 13x = 104
- Isolate <em>x</em>: x = 8

Step-by-step explanation:
1/6³ is simply multiplying the fraction 3 times.
or the numerator 3 times and the denominator 3 times.
It can be: 1/6 * 1/6 * 1/6 = <u>1 * 1 * 1 </u> = <u> 1 </u>
6 * 6 * 6 216<u />
or <u> 1³ </u> = <u> 1 </u>
6³ 216
Answer:12c + 30b ≤ 360
Step-by-step explanation:
Your math problem requires us to convert the word problem into math before we can solve the math. So let's try to do that first.
First, let's make a math equation to represent the amount of time.
The amount of time to bake "c" batches of cookies = (# of minutes per batch) x (# of batches) = 12 x c = 12c
Similarly for the amount of time to bake "b" batches of brownies = (# of minutes per batch) x (# of batches) = 30 x b = 30b
This is going to look like a format of:
(amount of time to bake cookies) + (amount of time to bake brownies) ≤ (total amount of time)
This person wants the (total amount of time) to be "at most 6 hours" but we can't just put "6" as our number because the other amounts of time are in "minutes".
6 hours * 60 minutes in an hour = 360 minutes
So our first equation becomes:
12c + 30b ≤ 360
