Answer:
L=8
Step-by-step explanation:
S=smaller number
L=larger number
S+L=5 : S=5-L
L=14+2S
substitute for S:
L=14+2(5-L)
solve for L:
L=14+10-2L
3L=24
L=8
Answer:
O No
Explanation:
Given equation: y = 13x + 12
To check if (2, 8) is a solution of the given equation.
Substitute x and y value in equation and check if it is true.
(x, y) = (2, 8)
simplify
This following statement is false and hence (2, 8) is not a solution.

Leave the whole number alone for now. Divide 41 by 80 and you get 0.5125
So your answer is 9.5125
Answer:
3.75 quarts, rounded to 3.8 quarts
Step-by-step explanation:
3 quarts of solution is 10% antifreeze, so 0.3 quarts are already antifreeze, and 2.7 quarts are not.
a(the antifreeze we already have)+x(what we're going to add)= 1.5*2.7
Let me explain. If we have 60% antifreeze, 40% is not. 60/40=1.5
Substitute a for 0.3
0.3+x=4.05 Subtract 0.3 from both sides
x=3.75
