Remember PEMDAS (Parentheses, Exponents, Multiplication ⇔ Division, Addition ⇔ Subtraction), which is the order you solve parts of an expression.
(7 + 5) ÷ 6 + 10² Add 7 and 5 (Parentheses)
12 ÷ 6 + 10² Square 10 (10 x 10) (Exponents)
12 ÷ 6 + 100 Divide 12 by 6 (Division)
2 + 100 Add (Addition)
102

Answer:
D
Step-by-step explanation:
there are 3 ft in a yard, so to find how many yards you multiply 3 time 12, which equals 36.
X + y = 150
x = y + 100
2y + 100 = 150
2y = 50
y = 25
shoes are 25 hoodie is 125
I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.
2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)
Next, I add 20 on both sides.
2x + 90 + 3x = 200º
I combine like terms (2x and 3x)
5x + 90 = 200º
I subtract 90 from both sides.
5x = 110º
Divide 110 by 5 to get x.
x = 22
======
For problem two, I label all the angles I know.
49º + 80º + r = 180º
I add 80 and 49.
129º + r = 180º
I subtract 180 and 129 and get 51º, which is your angle for R.
For angle X, you know that angle R plus angle X equals half of a circle, which is 180º
We know from before that 129º is 180º without R, so X is 129º
I hope this helps! Let me know if I'm wrong!
