Answer:
Step-by-step explanation:
Slope m is defined as m=(y2-y1)/(x2-x1) in this case
m=(218-155)/(22-15)=63/7=9
y=mx+b
y=9x+b, using point (15,155) we can solve for the y intercept b
155=9(15)+b
155=135+b, b=20 so the line is
y=9x+20
In thirty days there will be
y=9(30)+20=290 coins
<span>Fraction strips are bars drawn to show different fractions of unit such that one unit (a long bar) is drawn as two halves, and three thirds, and four fourths, and five fiths, and six sixths, and so on. To assess the equivalence of two fractions using fraction strips is very simple becasue you only need to put one strip below the other and see whether they have the same size or not. Two strips will have the same size if and only if the fractions are equivalent.</span>
The answer is 20 i’m pretty sure

Answer:
A. $2,000
Step-by-step explanation:
<em>Assuming that the money in the savings account will be used to pay off for tractor.</em>
<em>let the number of months be m</em>
Savings after m months will be 500+ 150m
After m months the installments paid will 200m
To find the months it will take to pay for the tractor in m months, savings and the installments will be the price of the tractor. As an equation it be represented as below:
500+150m +200m = 4000
150m + 200m = 4000-500 <em>(grouping like terms)</em>
350m = 3500 <em>(Making m the subject of the formula)</em>
350m/350 = 3500/350
m = 10
Substituting m into the equation of saving after m months
<em>Savings after m months will be</em> 500+ 150m
<em>Savings after m months will be</em> 500 + 150(10)
<em>Savings after m months will be</em> 500 + 1500
Savings after m months will be $2000
