Answer: 20 quarts of peanut oil worth 19 cents a quart must be mixed.
Step-by-step explanation:
Let x represent the number of quarts of peanut oil worth 19 cents a quart that would be in the mixture.
The total number of quarts in the mixture would be x + 100
The cost of the x quarts would be x × 19 = 19x cents
The cost of 100 quarts of the other peanut oil would be 25 × 100 = 2500 cents
The cost of the mixture would be
24(x + 100) = 24x + 2400
Therefore, the equation would be
19x + 2500 = 24x + 2400
24x - 19x = 2500 - 2400
5x = 100
x = 100/5
x = 20
Answer:
Step-by-step explanation:
M = miles
.25M + 160 = 360.00
.25 = 360 - 160
200/ .25
M = 800 miles
Answer:
not similar; corresponding sides are not proportional
Step-by-step explanation:
If the triangles were similar, corresponding sides would be proportional. That is, you would have ...
AX/AB = AY/AC
Here, those ratios are ...
6/24 ≠ 10/35
so, the corresponding sides are not proportional, and the triangles are not similar.
Answer:
x - 5y = 30
Step-by-step explanation:
If you subtract x from both equations, you'll get -x. If you divide -5y, you'll end up with 1/5x and 6. The intercept doesn't matter but the slopes are parallel which means they'll never intersect anyway
Answer:
B and C
Step-by-step explanation:
A. y + 11 = 22 → subtract 11 from both sides:
y = 11
---------------------------------------------------------------------------
B. 8 = 18 - y → subtract 18 from both sides:
-10 = -y → divide both sides by -1:
10 = y
----------------------------------------------------------------------------
C. 60 = 6y → divide both sides by 6:
10 = y
-----------------------------------------------------------------------------
D. = 4 → multiply both sides by 5:
y = 20
-----------------------------------------------------------------------------
E. 10y = 20 → divide both sides by 10:
y = 2
