USE THE ORDER OF OPERATIONS (PEMDAS) in all questions.
PEMDAS is:
Solve the parentheses first
Then the exponents
Then multiplication and division (from left to right, what ever comes first)
Lastly, addition and subtraction (from left to right, what ever comes first in the equation)
10) b. 60
11) b. 100
12) c. 384

(Com.ment me if u have any questions)
Answer:
5)
<2 = 79°
<1 = 101°
<3 = 101°
6)
x = 5
y = 3
Step-by-step explanation:
5)
<2 = 79°
<1 = <3 = 180 - 79 = 101°
6)
4y - 6 = 2y
2y = 6
y = 3
2x + 4 = x + 9
x = 5
A common denominator is 12
Answer:
1. Substitute y = -3x +4 for y in the first equation
2. Combine like terms and isolate x
3. Substitute in x into the 2nd equation to get y
Step-by-step explanation:
1. Substitute y = -3x +4 for y in the first equation
2x- (-3x+4) = 6
2. Combine like terms
5x -4 = 6
5x -4 +4 = 6+4
5x=10 Divide by 5 to isolate x
5x/5 =10/5
x=2
3. Substitute in x into the 2nd equation to get y
y = -3x +4
y = -3(2) +4
y = -6+4
y=-2
(2,-2)
