No, to find the least number of burgers and buns, you should find out the LCM of 15 and 6, not their product.
LCM = 30,
so they need to buy atleast 30 of each item.
Answer:
-20
Step-by-step explanation:
In the x quarts of 2% fat milk, there is 0.02x quarts of fat.
in the y quarts of 4% fat milk there is 0.04y quarts of fat.
together, there is (x+y) quarts of milk, and 0.24 quarts of fat.
the equations are:
x+y=9
0.02x+0.04y=0.24
multiply the first equation with 0.02: 0.02x+0.02y=0.18
subtract this new equation from equaition 2 to eliminate x:
0.04y-0.02y=0.24-0.18
0.02y=0.06
y=3
x=9-3=6
x is twice as much as y.
He used twice as much as the 2% fat milk than the 4% fat milk.
so the first choice is the correct answer.
Answer:
y=4x+23
Step-by-step explanation:
<u>Convert given equation into slope-intercept form:</u>
12x-3y=10
4x-y=10/3
-y=10/3-4x
y=-10/3+4x
y=4x-10/3
Because the new equation must be parallel to the old equation, the slope stays the same, but the y-intercept changes based on the point that the new equation should pass through:
y=4x+b
3=4(-5)+b
3=-20+b
23=b
This means the slope-intercept form of the equation of the line that passes through (-5,3) and is parallel to 12x-3y=10 is y=4x+23
