Determine where the decimal point belongs in each product. 1.7 × 2.5 = 425 The decimal point belongs after the . 3.62 × 1.7 = 6154 The decimal point belongs after the .

Decimal point in product is the sum of the decimal points in the numbers which we are multiplying.

For ex :

2.6 × 6.7 = 17.42

1    +    1  =  2

For, 1.7 × 2.5  the sum of decimal in each number is 1 and 1 .

So, decimal in product is at 2 i.e 4.25 .

For, 3.62 × 1.7 the sum of decimal in each number is 2 and 1.

Decimal in product is at 2 + 1 = 3 i.e 6.154 .

Therefore, solution is 1.7 × 2.5 = 4.25 and 3.62 × 1.7 = 6.154 .

Hence, this is the required solution.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

x+10

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
