1.
2x-2=2x+32x-2=2x+3
notice
2x-3=2x+2
minus 2x both sides
-3=2
false
no solution

2. 5m-4=7m+85m-4
add 4 to both sides
5m=92m
therefor m=0
but wait
5m-4=7m+8
5(0)-4=7(0)+8
-4=8
false
no solution


3.
y+7=y-3
minus y both sides
7=-3
false
no solution



none of them have solutions

Point A is located at –24 and point C is located at 36 on the number line below. Which value would represent point B, halfway be
aniked [119]
To find the midway point of 2 numbers, we find their sum and divide that by 2. For this, we add -24 and 36 ( which amounts to 12) and divide that by 2, meaning that midpoint B is 12/2=6

Pls can someone help
Bumek [7]

Answer:

You need to try and find the total cost of the food and drink and subtract it from the amount of money Simon pays.

Two cups of coffee costs 2.78 so -

2.78 + 2.78 = 5.56

One piece of cake costs 2.85 so the total amount is

5.56 + 2.85 = 8.41

Now we know the total, we can subtract it from the money given.

10 - 8.41 = 1.59

<u>Simon will get 1.59 in change.</u>

Leila says that 75% of a number will always be greater than 50% of any other number.
Gemiola [76]
That is not correct, it depends on the numbers you are referring to. For instance, 75% of 100 is 75, but 50% of 1000 is 500, so in this case the 50% of a number is higher than 75% of another number. Although, is true that 75% is higher than 50% of the same number always.

Kaden works 5 days. The median number of hours he works is 3. The mean number of hours he works is 4.
alisha [4.7K]

Answer:

(a) 1, 2, 3, 6, 8

Step-by-step explanation:

Given

Median = 3

Mean = 4

Required

The sequence of hours worked each day

<em>See attachment for options</em>

From the question, we understand that:

Median = 3

This means that, the middle number is 3 (when sorted)

So, we can conclude that (b) and (c) cannot be true because their middle numbers are 6 and 5 respectively

Next, is to determine the mean of (a) and (d)

The mean of a data is calculated as:

\bar x = \frac{\sum x}{n}

So, we have:

(a)

\bar x = \frac{1+ 2+ 3+ 6+ 8}{5}

\bar x = \frac{20}{5}

\bar x = 4

(d)

\bar x = \frac{1+ 2+ 3+ 4+ 5}{5}

\bar x = \frac{15}{5}

\bar x = 3

Option (a) is true, because it has:

Median = 3

Mean = 4
