Answer:
x = 8.5
Step-by-step explanation:
You have all three angles already, so it's easy: 90°, (4x - 8)°, (6x + 13)°
The sum of all angles is 180°
90 + (4x - 8) + (6x + 13) = 180
10x + 95 = 180
- 95 -95
10x = 85
x = 8.5
Answer:
2 1/2
Step-by-step explanation:
Turn both fractions into improper fractions, multiply the whole number by the denominator and add the numerator.
4 3/4
4 * 4 + 3 = 19
19/4
2 1/4
2 * 4 + 1 = 9
9/4
Now since she drank 2 1/4 gallons of juice, subtract 9/4 from 19/4.
19/4 - 9/4 = 10/4
Now turn back into a mixed fraction, do this by putting 4 into ten twice and taking the remainder and putting it as numerator:
4 * 2 = 8
10 - 8 = 2
2 1/2

Answer:
<h3>-90</h3>
Step-by-step explanation:
To use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) left to right.
Please Excuse My Dear Aunt Sally!
BOMDAS- (Brackets, Of, Multiply, Divide, Add, and Subtract) from left to right.
First, do parenthesis.
(3-21)=-18
-18(3+2)
Add.
3+2=5
-18*5
Multiply.
-18*5=-90
-90
So, the final answer is -90.
