A calculator screen shows a number in scientific notation as 1.16E‒7. Write this number in standard form.

Part (i)

Answer:  m/n

--------------------

Explanation:

You divide the total bill over the number of people at the dinner. This leads to the quotient and the amount each person pays (each person pays the same amount).

====================================================

Part (ii)

Answer:  80 dollars

--------------------

Explanation:

Plug in m = 400 and n = 5 to get

m/n = 400/5 = 80

====================================================

Part (iii)

Answer:  m = 7x

--------------------

Explanation:

x = m/n

x = m/7

7x = m ... multiply both sides by 7

m = 7x

The total bill is 7 times of what each person paid.

====================================================

Part (iv)

Answer:  7 people

--------------------

Explanation:

x = 20 is the amount each person paid

m = 140 is the total bill

n = number of people who went to dinner

x = m/n

20 = 140/n

20n = 140 ..... multiply both sides by n

n = 140/20 ..... divide both sides by 20

n = 7

Seven friends went to do dinner, splitting a $140 bill, paying $20 each

Answer:

m/n; $80; 7*x; 7 friends

Step-by-step explanation:

(I) $x=$m/n

(II) $x=400/5=$80

(III) $m=7*x

(IV) n=140/20=7

Given:-

Step-by-step explanation:

4z+7= 31

4z= 31-7

4Z= 24

Z= 24/4( dividing by 2)

z = 6/1

Answer:

  -2 ≤ x < 12

Step-by-step explanation:

-15x +4 ≤ 34

Add 15x-34 to both sides

  -30 ≤ 15x

Divide by 15

  -2 ≤ x

__

-6x +70 > -2

Add 6x +2 to both sides

  72 > 6x

Divide by 6

  12 > x

__

The two solution spaces overlap. Since the AND of the two inequalities is involved, the solution of both is just that part of the number line where there is overlap.

The solution is ...

  -2 ≤ x < 12

x = 3/13

Step-by-step explanation:

the answer it gave me is 29.8.

Answer:

to solve, really, you just combine like terms and follow the formula

Step-by-step explanation:

for example:

y2-y1=m(x-x1)

y-3=4(x-5)

y-3=4x-20

y=4x-23

Answer:

x = 3.75 or [tex]3\frac{3}{4}[/tex]

Step-by-step explanation:

17 = -13 - 8x

add 13 to both sides

17 + 13 = -13 + 13 + 8x

30 = 8x

divide both sides by 8

30/8 = 8x /8

3.75 = x

Answer:

-2 < x < = 4

Step-by-step explanation:

Cause the dot at -2 isn't full, means that it's not equal to it.

The opposite thing happens at 4

Answer:

x=9

Step-by-step explanation:

First, midpoint means “the middle” so that mean that segment AB is half of AC. You can make an equation: 5x+18=4.5+6.5x. After that, you have to move the numbers on one side and the variables on the other.

You then come up with 13.5=1.5x

Divide both of them by 1.5 and then you get x=9

Answer:

X=9

Step-by-step explanation:

Okay first Hello! :)

so, B is the mid point of the segment midpoint means the half way

so, if AB= 5x+18 is the half to get the whole you would need to times it by 2

you get 10x+36

so now you equal them together

10x+36= 13x +9

Always move your smaller x, and now you got

3x+9=36

move your 9 over and switch the sign you get

3x=27

divide by three and you get

X=9
