Answer:
Like terms means that the numbers have the same variable after them or they don't have a variable at all. It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.
For example, x + 3x = 1x +3x. Then I add the numbers in the front and I get 4x.
If it had been 4x + 7x + 3, my answer would have been 11x +3. That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

Answer:
secθ = - 2
Step-by-step explanation:
Using the identity
sec²θ = 1 + tan²θ
= 1 + (
)² = 1 + 3 = 4 ( take the square root of both sides )
secθ = ± 
= ± 2
Since secθ < 0 in the third quadrant , then
secθ = - 2
Do a squared plus b squared equals c squared
Answer:
Step-by-step explanation:
R = report length
R = 40 + (3/8)R + (1/3)R
3/8 = 3*3/8*3 = 9/24
1/3 = 8*1 / 3*8 = 8/34
R = 40 + (9/24)R + (8/24)R
R = 40 + (17/24)R Subtract 17/24 from the left
R-17/24 R = 40
7/24 R = 40 Multiply both sides by 24
7R = 40 * 24
7R = 960 Divide by 7
R = 960/7
R = 137.1 which breaks the rounding rule and becomes 138 because something has to be typed on page 138
Answer:
A) 2 x 0.80= 1.60
Step-by-step explanation:
get 80 on the cents and times it by how many soda's you got (2) then times it by normal which will get you 16 so add a zero at the end to make the answer.
