You have to distribute the 4 to the numbers in the parenthesese. So 4 times 3x which is 12x and 4 times 5 which is 20 so now you get 12x plus 20 equals 8. Now you have to subtract 20 from 8 which is -12 so now you have 12x=-12 now divide the 12 from x and 12 from -12 and so now you have x=-1
Answer: slope = 4
Step-by-step explanation:
slope = m = rise/run = y1-y2/x1-x2
9-1/5-3 = 8/2 = 4
Answer:
it is an arithmetic sequence
m is slope
b is y-intercept
Step-by-step explanation:
<span>4% is the same as 0.04 </span>
<span>so 0.04 x n = 56 where "n" is some number </span>
<span>0.04n = 56 Divide both sides by 0.04 </span>
<span>n = 1400</span>
Answer:
1200 students at the school
Step-by-step explanation:
Let x be the total number of students at the school
50% ride the bus
600 students ride the bus
x*50% = 600
Changing to decimal form
.50x = 600
Divide each side by .5
.50x/.5 = 600/.5
x =1200
1200 students at the school
