To convert mixed fractions to improper fractions:
a b/c=(ac+b)/c so we have:
43/10+127/30+37/15 now making all terms have a common denominator of 30
(43/10)(3/3)+(127/30)(1/1)+(37/15)(2/2)
129/30+127/30+74/30
(129+127+74)/30
330/30
11 acres
Now
11a(25b/a)=275 bags of fertilizer.
1st one is the correct one
Answer:
220 cases
Step-by-step explanation:
Each pallet contains 40 cases of tiles.
The yard has 10 complete pallets.
The total number of cases of tiles is therefore:
40 * 10 = 400 cases
If 180 cases are removed for the customer, then the number of cases of tiles remaining is:
400 - 180 = 220 cases
220 cases of tiles will be remaining.
Answer:
x = -78
Step-by-step explanation:
Write and solve an equaiton of ratios, as follows:
hypotenuse to hypotenuse:
57 51
----------------- = ---------------
2x + 7 x + 4
Cross-multiplying, we get:
57x + 228 = 102x + 351
Combining the x terms on the right, we get:
228 = 45x + 351
Combining the constants on the left:
-123 = 45x, and so x = -123/45 = -78
x = -78
