M < 2 and m < 6 are corresponding angles and are equal....so < 6 = 132.
< 6 and < 8 form a line and are equal to 180
< 6 + < 8 = 180
132 + < 8 = 180
< 8 = 180 - 132
< 8 = 48 <===
The first expression is equivalent to B
The second expression is equivalent to A
The third expression is equivalent to C
You are basically adding like terms. For example for the first expression, it is 7x^2 + 2x^2, which equals 9x^2. Remember since you're adding, do not add the exponents.
Doing a bit of guess and check, we can notice that the amount of leaves is one less than the number of inches of vine. Writing it out, we get x-1=y (the amount of inches-1=the amount of leaves)
There are 14 girls in HR 218 because 24/12 is 2, meaning that the ratio needs to be multiplied by 2/2 in order to figure out what 7/12 is. 7/12*2/2 is 14/24, therefore there are 14 girls in HR 218.
According to the order of operations, multiplication and division are performed before addition and subtraction.
... 8 - 12 ÷ 2 + 3
... = 8 - 6 + 3 . . . . . . 12÷2 = 6
... = 2 + 3 . . . . . . . . . 8-6 = 2
... = 5
