The first step is to move the terms of the expression around so that the like terms are next to each other.
6a - 4a + 3xy - 7xy Now, combine like terms (6a - 4a) and (3xy - 7xy)
2a - 4xy
Answer:
65 in and 39 in respectively
Step-by-step explanation:
Let r be the common ratio; when we multiply both L and R by this common ratio, we'll get the actual length and actual width of the rectangle, Recalling that the formula for the perimeter of a rectangle is P = 2L + 2R, we get:
2(5r) + 2(3r) = 16r = 208 in
Then r = 208/16 = 13
Thus, the actual length is 5(13 in) and the actual width is 3(13 in.),
or 65 in and 39 in respectively.
As a check, calculate 65 in / 39 in; this comes out to 5:3, as required.
Then
Answer:
Unit rate = 1 1/2 cups per serving
Step-by-step explanation:
1/2 serving has 3/4 cup
1 serving
3/4 * 1/2 = 3/4 * 2/1 = 6/4 = 6/4 / 2 = 3/2 = 1 1/2
Copy the expression.
Then copy the expression again, but replace c with 8.
Then do the operations.
7/8 * c =
= 7/8 * 8
= 1/8 * 7 * 8
= 1/8 * 8 * 7
= 1 * 7
= 7
Answer:
Step-by-step explanation:
Combine like terms, rewrite the equation and perform the operations between the coefficients,
