Ok, so if janelle earns 16 dollars for 2 hours, then this means that she earns 8 dollars for 1 hour.
So now you will divide 40 by 8 to get 5 hours

Write the decimal for 1/8 Explain why this decimal is called terminating decimal

Answer:

0.125

This is a terminating decimal because after a finite amount of digits, the decimal comes to an end. The decimal does not continue for an infinite amount of digits.

A line passes through the points (-4,1) and (-3,3). This line can be modeled by the equation y = mx + b.

docker41 [41]

Answer:

m= 2

b=9

Step-by-step explanation:

-4, 1 -3,3

put it into y2-x2 divided by y1-x1

y2= 3

x2= 1

y1= -3

x1=-4

3-1 divided by -4--3= 2/1 =2x

get one of the points either -4,1 or -3,3

If you use -4,1 -4=x 1=y

put it into y=mx+b and you get 1= -4(2)+b simplify

1=-8+b add 8 to other side b=9

what is fourteen less than five times a number is three times the number and what is twelve more than seven times a number equal

andrey2020 [161]

If I am reading the equations correctly, they are:
5x - 14 = 3x AND 7x + 12 = x - 6

If this is correct, the first one would be worked out like this:
5x (- 5x) - 14 = 3x (- 5x)
- 14 = - 2x
- 14 (/ - 2) = - 2x (/ - 2)
7 = x

The second would be worked out like this:
7x + 12 (+ 6) = x - 6 (+ 6)
7x + 18 = x
7x (- 7x) + 18 = x (- 7x)
18 = - 6x
18 (/ - 6) = - 6x (/ - 6)
- 3 = x

I hope this is what you are looking for :)

Compute<br><br> 8*4-4 divided by 2 +1

iragen [17]

Solution of 8 x 4 - 4 divided by 2 +1 is 9.33

<h3><u>Solution:</u></h3>

Given that,

8 x 4 - 4 divided by 2 +1

We have to compute the above equation

Let us write the given sentence mathematically:

$\rightarrow \frac{8 \times 4-4}{2 + 1}$

Let us BODMAS rule to solve the above expression

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.

So let us first perform multiplication of 8 and 4 in numerator

$\rightarrow \frac{32 - 4}{2 + 1}$

Now we can perform addition of 2 and 1 in denominator

$\rightarrow \frac{32-4}{3}$

Now we can perform subtraction of 4 from 32 in numerator

$\rightarrow \frac{28}{3}$

Now perform division of 28 by 3

$\rightarrow \frac{28}{3} = 9.33$

Thus solution of 8 x 4 - 4 divided by 2 +1 is 9.33
