What is −3/8 as a decimal and as a percent?

Answers

Answer 1

Answer: To find a fraction as a decimal you would divide the denominator by the numerator.

Decimal:
-3/8 = -.375

Then for the percentage you would move the decimal two places to the right.

Percentage:
-37.5 (Since the number to the right isn't a zero we can't drop it) therefore the percentage would be -37.5%

Describe the pattern in the equation. Then solve the equation.0.3x + 0.03x + 0.003x + 0.0003x + ....= 3

Answers

Each term is 10 times smaller than the previous one.

$0.3x+0.03x+0.003x+0.0003x+\ldots=3\nx(0.3+0.03+0.003+0.0003+\ldots)=3\nx\cdot0.\overline{3}=3\nx\cdot(1)/(3)=3\nx=9$

Which of the following systems of equations is an example of one where substitution is the best method?

Answers

Answer:

option c is the correct ans .

because we can easily substitute the value of y in equn 2 to get value of x..

Answer:

To me, the third one is the best.

Note: y has been made subject of formula which makes it easy to substitute it into equation 2 and find x .

Step-by-step explanation:

What is the value of the expression shown when x = –3?

7 + 2(x – 9) – (x + 2)

Answers

To find the value of your expression, you could use the following steps;

First lets substitute the value of x in the equation;

7 + 2(-3 - 9) - (-3+ 2)

Next, simplify the parenthesis;

7 + 2(-12) - (-1)
7 - 24 + 1 = -16

So your final answer would be; -16

sub -3 for every x

7+2(-3-9)-(-3+2)
PEMDAS
simplify inside parenthases first
-3-9=-12
-3+2=-1
now we have
7+2(-12)-(-1)
multiplictaion
2(-12)=-24
-(-1)=1
now we have
7-24+1
-17+1
-16 is reault
