First you do 2 x 3x which will be 6x you then look to see whether there is a plus or minus next we see that it is a minus after this you do 2 x 5 which is 10 so the first bit is 6x - 10 we then look to see whether we have a plus or a minis we look to see that it is a plus you then work out the next bracket so you do 3 x 2x to give us 6x we see that we need to add a plus then do 3 x 3 which is 9 together it is 6x - 10 + 6x + 9 so now we have to simplify it so you do 6x + 6x which is 12x then do -10 + 9 which is -1 so the answer is 12x - 1

MAVERICK [17]

Answer:

Your answer is 10

Step-by-step explanation:

So if you have to pay 55 out front and then continue to pay 19.50 monthly the equation will look like this:

19.50*m + 55 = x

(M stands for month)

She has 250 dollars to spend so add that in for x

19.50*m + 55 = 250.  

Use inverse operations.

250-55 and 55-55

19.50*m = 195

195/19.50 and 19.50/19,50

m=10

Your answer is 10

babymother [125]

Answer:

(300,000 + 20,000 + 0 + 700 + 40 + 9)

Step-by-step explanation:

The expanded form of 320, 749

Segmenting each digit in the figure based on its place value :

3 = 100 thousand place = 3 * 100,000 = 300000

2 = ten thousand place = 2 * 10,000 = 20000

0 = thousand place = 0 * 1,000 = 0

7 = hundred place = 7 * 100 = 700

4 = tens place = 4 * 10 = 40

9 = unit place = 9 = 9

(300,000 + 20,000 + 0 + 700 + 40 + 9)
