Answer:
9
Step-by-step explanation:
-4(6x+3)= -12(x+10)
<u><em>Let's do the first part:</em></u>
-4(6x+3)
<em>**distribute**</em>
-4 x 6x = -24x; -4 x 3 = -12 ->>> -24x - 12
<u><em>Let's do the second part:</em></u>
-12(x+10)
<em>**distribute**</em>
-12 x x = -12x; -12 x 10 = -120 ->>> -12x -120
-24x -12 = -12x - 120
<em>**Move variable to the left-hand side and change its sign**</em>
-24x +12x -12 = -120
-12x - 12 = -120
-12x = 108
x = 108/-12
x=9
Answer:
Step-by-step explanation:
6+2 = 8 your welcome or 4 x 2 = 8 :)
I think this is correct:
110 + 75 = 195
195 / 2 = 97.5
I am not fully sure about this, consult your teacher
Answer:
We know that the prize of 6 bags of marbles is $18.
Then if each one of the bags costs C, the 6 bags will cost a total of 6 times C.
Then the cost is:
6*C
and this is equal to $18
6*C = $18
Now we want to solve this for C, remember that we can divide both sides of the equation by the same number, then let's divide both sides by 6:
6*C/6 = $18/6
C = $18/6 = $3
Each bag costs $3.
Below you can see a double number line, where above is the number of bags and below is the prize:
Answer:
i) Nazaneen has 3*m marbles.
ii) Karly has m + 4 marbles.
Step-by-step explanation:
a) The given data is:
Shireen has m marbles.
Nazaneen has three times as many marbles as Shireen.
Knowing that Shireen has m marbles, we can conclude that Nazaneen has:
3*m marbles.
Karly has 4 more marbles than Shireen, then Karly has m + 4 marbles.
Then the equations are:
Shireen = m
i) Nazaneen has 3*m marbles.
ii) Karly has m + 4 marbles.
