If 7.80 buys 6 chocolates then 15.60 should buy 12 with a remainder of 2.60
7.80 divided by 6 is 1.30 and 1.30 +1.30 = 2.60 so 12 +12 = 14
Answer: Corn = 200 acres
Wheat= 400 acres
Step-by-step explanation:
Let the number of acres of corn = c
Let the number of acres of wheat = w
The Mulder Farm has 600 acres of land allotted for raising corn and wheat. This will be:
c + w = 600
c = 600 - w
Cultivation cost equals:
= 40c + 25w = 18000
Since c = 600 - w, we slot it into the equation
40c + 25w = 18000
40(600 - w) + 25w = 18000
24000 - 40w + 25w = 18000
Collect like terms
24000 - 18000 = 40w - 25w
6000 = 15w
w = 6000/15
w= 400
400 acres of wheat will be planted
Since c + w = 600
c = 600 - 400
c = 200
200 acres of corn should be planted
Answer:
-4.88
Step-by-step explanation:
-5+(-3) = (-8)
7/10 = 98/140
3/7 = 60/140
15/4 = 525/140
525/140 + 60/140 + 98/140 = 683/140
683/140 = 4 123/140
4 123/140 = 4.88 (2dp)
4.88+(-8) = -4.88
Answer:
k≥-1.5
Step-by-step explanation:
-(5k-3) ≤ 15 + 3k
-5k+3 ≤15 +3k
+5k +5k
3≤15+8k
-15 -15
-12 ≤ 8k
divide both sides by 8
-1.5 ≤ k
or k≥-1.5
Hope this Helps!!!
