Answer:
n = 15
Step-by-step explanation:
6(1+n)=8n-3(n-7)
Distribute
6 +6n = 8n -3n +21
Combine like terms
6+6n = 5n +21
Subtract 5n from each side
6+6n-5n = 5n-5n +21
6 +n = 21
Subtract 6 from each side
6-6+n = 21-6
n = 15
Answer: 120 schools
Step-by-step explanation:
3,120 students competed in a statewide athletic competition and each participating school district sent 26 students to the athletic competition.
Total number of students= 3120
Total students sent by each school= 26
Number of participating school districts= Total number of students ÷ he students sent by each school
= 3120 / 26
= 120 students
There are 120 participating schools in the competition
Answer:
D) y = -1/2x + 4
Step-by-step explanation:
Points on the graph: (0, 4) and (8, 0)
Slope:
m=(y2-y1)/(x2-x1)
m=(0 - 4)/(8-0)
m= -4/8
m = -1/2
Slope-intercept:
y - y1 = m(x - x1)
y - 4 = -1/2(x - 0)
y - 4 = -1/2x
y = -1/2x + 4
Answer:
C. -2.5 - 6.5n
Step-by-step explanation:
i just think thats the answer
One liter is equal to 1000 milliliters. Use the conversion to find your answer. 1000 milliliters / 5mL per tube = 200 tubes
