Answer:
x = 11.75
y = 11.5
Step-by-step explanation:
By Elimination Method:
7x - 3y = 48 ---- (1)
-
<u> 2x + y = 35 ----</u>- (2)
Multiply equation (1) by 2 and equation (2) by 7
14x - 6y = 96
-
<u> 14x + 7y = 245 </u>
<u> 0 -13y = -149</u>
-13y = -149
y = -149/-13
y = 11.5
From equation (2); replace y with 12
2x + y = 35
2x + 11.5 = 35
2x = 35 - 11.5
2x = 23.5
x = 11.75

Answer:
Step-by-step explanation:
If 
then
by combining like terms. (I'm thinking you might have mistyped the problem because this representation is weird).
The laws for radicals are derived directly from the laws for exponents by using the definition a m n = a m n . The laws are designed to make simplification much easier. It is important to reduce a radical to its simplest form.
Answer:
4:2:3
Step-by-step explanation:
16 blue marbles,8 green marbles and 12 red marbles.
Ratio of blue to green to red
blue:green:red
16:8:12
We can divide each term by 4
16/4:8/4:12/4
4:2:3
