There would be 252 robbers because the rate of change is 21 and 12*21=252
Answer: In first question answer is -28x+4
In second question required inequality is 3x+100 < 2x-250
Step-by-step explanation:
1. Since, here the given expression is 4(x+5)-8(2+4x)
= 4x+20-16-32x ( By distributive property)
=-28x +4 ( By operating like terms)
2. Here, let the number is x.
Then according to the given question, three times the number of candy is increased by 100
That is, 3x+100
And, 250 less than the two times of the candy
That is, 2x-250
And, 3x+100>2x-250
Which is the required expression.
Hence she should subtract 250 from 2x not 2x from 250.

Maria uses 50g a day, so to know how many days takes eating the whole packet just divide 1500 by 50.
Answer:
x = 15
Step-by-step explanation:
37*2 = 74
360-74 = 286
286 = 2(9x + 8)
143 = 9x+8
135 = 9x
15 = x
The error is that the graph is moving up two and over one. Basically using the slop 2/1 instead of 1/2. The slope is rise/run, so it should rise up 1 unit and run 2 units to the right.
