Answer:
1.96
Step-by-step explanation:
A farmer sells 9.8 kl of apples and pears
4/5 of this weight is apples, while the rest are pears
Therefore the wight of pears can be calculated as follows
Let x represent the weight of pears
9.8= 4/5×9.8 + x
9.8= 0.8×9.8+x
9.8= 7.84+x
9.8-7.84= x
x= 1.96
Answer:
w = -10
Step-by-step explanation:
w + 4 = (-6)
Subtract 4 from each side
w+4-4 = -6-4
w = -10
30 percent decrease
Step-by-step explanation:
looking at this i know its a percent decrease
so how do we find percent decrease ?
first we subtract the first value 39.39 & the final value 27.57
39.39-27.57 = 11.82
then we divide 11.82 by the first value
like this 11.82÷39.39 = 0.3000
then we multiply what we got by 100
0.3000×100= 30 percent
the way that most people mess up is when they divide sometimes they might do 39.39 divided by 11.82 instead of 11.82÷39.39.
