Seven times the sum of a number and 2 is equal to 9

Answers

Answer 1

Answer: Let x = a number

7(x + 2) = 9

Then we solve for x. First, distribute:

7x + 14 = 9

Subtract 14 from both sides:

7x = -5

Divide by 7 on both sides:

$x= (-5)/(7)$

The number is then -5/7.

On the spinner below, what is P(red or blue)? point)4. On the spinner below, what is P(not purple)? point

Answers

Answer:

$\text{P(red or blue)}=(3)/(4)\n\n\text{P(not purple)}=1$

Step-by-step explanation:

3. From the given spinner, the number of red sections = 3

Number of blue sections= 3

Then, the number of sections which are red or bl;ue = 3+3=6

Total sections=8

Then ,

$\text{P(red or blue)}=\frac{\text{Number of sections which are red or blue}}{\text{Total}}\n\n\Rightarrow\text{P(red or blue)}=(6)/(8)=(3)/(4)$

4. From the given spinner, the number of purple sections =0

Total sections= 8

Number of sections which are not purple =8

Now, $\text{P(not purple)}=\frac{\text{Number of sections which are not purple}}{\text{Total sections}}\n\n\Rightarrow\text{P(not purple)}=(8)/(8)=1$

the first one is 3/4

How do you change a fraction to a decimal

Answers

A fraction is a short way of writing a division problem.
When you see a fraction, it means

(the top number) divided by (the bottom number).

If you go ahead and actually do the division, the answer to it
is the decimal form of the fraction.

Examples:

Fraction 1/2 . 1 divided by 2 = 0.5 .

Fraction 1/4 . 1 divided by 4 = 0.25 .

Fraction 3/10 . 3 divided by 10 = 0.3 .

To convert a Fraction to a Decimal manually, follow these steps: Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s. Step 2: Multiply both top and bottom by that number.
