If y=-8 when x=-2,find x when y =32

Mathematics

So when y=32 it is 4x more than the original y which means they've multiplied it by four. Whatever you do to one you have to do to the other side so you multiply 2 by 4 to get 8 so x=8

1.06×2.29=?????????????????
mario62 [17]

Answer:

2.4274

Step-by-step explanation:

This is just a simple multiplication problem.

One way to do this is by converting both decimals into fractions:

1.06 = 1 + 0.06 = 1 + 6/100 = 1 + 3/50 = 53/50

2.29 = 2 + 0.29 = 2 + 29/100 = 229/100

Multiplying these two fractions, we get:

\frac{53}{50} *\frac{229}{100} =\frac{12137}{5000}

Now, we can just convert this into a decimal by using a calculator:

12137/5000 = 2.4274, which is our answer.

Of course, you could just put the numbers in a calculator, which would be much less time-consuming.

How do you find percent of a number mentally
olga55 [171]
It isn't easy really but you can always divide the number out. For example 50% of 200 is 100 by dividing 200 by 2 or 25% of 100 is 25 by dividing 100 by 4 since 25% is equivalent to 1/4
