Compute: (1 2/5 +3.5÷1 1/4 )÷2 2/5 +3.4÷2 1 /8 −0.35

nikdorinn [45]

Answer:

Answer: 3

Step-by-step explanation:

Use BODMAS

Step 1: Open bracket (1 2/5 +3.5÷1 1/4 )

Convert mixed fractions into improper fractions

7/5 + 3.5 ÷ 5/4

Divide 3.5 by 5/4

7/5 + 2.8 = 4.2

Step 2: Carry out all divisions

Convert mixed fraction into improper fractions

4.2 ÷2 2/5 +3.4÷2 1 /8 −0.35

4.2 ÷ 12/5 + 3.4 ÷ 17/8 - 0.35

1.75 + 1.6 - 0.35

Step 3: Solve

1.75 + 1.6 - 0.35

3.35 - 0.35

Answer = 3

The united states government produced about 10.25 billion pennies one year.

Elenna [48]

1) 10.25 x 10^9 in scientific notation is 1.025 x 10^10

2) Now you have to subtract 10.25x10^9 - 3.0x10^7

To make that you have to put both numbers with the same power of ten.

1025x10^7 - 3.0x10^7 = 1022x10^7 more pennies than half-dollars.

Need help I'm getting it wrong I don't understand

W/3-15=12
remember, you can do ANYTHING to an equaiton as long as you do it to both sides
get w by itself

$\frac{w}{3}-15=12$
add 15 to both sides
$\frac{w}{3}+15-15=12+15$
$\frac{w}{3}+0=27$
$\frac{w}{3}=27$
tiemes both sides by 3/1
$\frac{3w}{3}=27*3$
$(\frac{3}{3})w=81$
$1w=81$
$w=81$
