Alicia is solving the equation 2.3x-1.6=8.8-2.9x. Which equations represent possible ways to begin solving for x? Check all that

My name is Ann [436]

While solving an equation the first step is to get the variable (x) alone on either side.

2.3 x - 1.6 = 8.8 - 2.9 x

+ 1.6 +1.6

2.3 x = 10.4 - 2.9 x

2.3 x - 1.6 = 8.8 - 2.9 x

-8.8 - 8.8

2.3 x - 10.4 = 2.9 x

2.3 x - 1.6 = 8.8 - 2.9 x

+2.9 x + 2.9 x

5.2 x -1.6 = 8.8

Multiply (2.5x10^-10) (7x10^-6)

serious [3.7K]

We want to multiply $2.5\cdot10^{-10}$ by $7\cdot10^{-6}$ .

The numbers are written in scientific notation. So we expect the answer also to be in scientific notation.

the multiplication of the 10's, using the exponents rule is :

$10^{-10}\cdot 10^{-6}=10^{-10+(-6)}=10^{-10-6}=10^{-16}$

the multiplication of the other 2 numbers is:

$2.5\cdot7=17.5=1.75\cdot10$

(we write the number so that it has only one digit to the left of the decimal point).

Thus,

$(2.5\cdot10^{-10})\cdot(7\cdot10^{-6})=1.75\cdot10\cdot10^{-16}=1.75\cdot10^{-15}$

Answer: $1.75\cdot10^{-15}$

The smiths want to buy a 9 ft. by 12 ft. carpet and center it in a 15 ft. by 20 ft. room. can a 3 1/2 foot by 12 foot couch be p

Allushta [10]

To answer this question, you should draw a picture of a large rectangle with labels 15 ft by 20 ft.

Inside the large rectangle, draw another rectangle (the carpet) with dimensions 9 ft by 12 ft.

When you do this, you will see that you will have 3 feet of space on both sides of the longer wall (15 - 9 = 6; 6/2 = 3 feet).

On the shorter wall, you will have 4 feet of space (20 - 12 = 8; 8/2 = 4 feet).

You will have room for your couch on the shorter wall without touching the carpet.
