To solve the problem, let x be the number of monthly quota of problems. Below is the list of the problems solved each week,
1st week - 0.25x
2nd week - 1.10(0.25x)
3rd week - 0.6(0.25x + 1.10(0.25x))
4th week - 320
To solve for the monthly quota, equate the sum of all the problems solved to x and determine its value. Thus, the students solved 2000 problems all in all.
Answer: y=–2x–5
Step-by-step explanation:
The equation of a straight line:
y=mx+c
m must be the same for the two lines to be parallel.
y=mx+c
y=–2x+8 → m=–2
For a new equation:
x=–1, y=–3, m=–2, c=?
y=mx+c → –3=–2×(–1)+c
–3=2+c
c=–5
So:
y=–2x–5
Answer in scientific notation: 8.3x10^-3
Answer:
6 feet
Step-by-step explanation:
240 feet : 10 inches
24 feet : 1 inch
? feet : 1/4 inch
to get from 1 to a 1/4 you divide by 4, so you do 24 ÷ 4
24 ÷ 4 = 6
Answer: negative 7 and 7/15
Step-by-step explanation:
AB = 7/1 = 7
AC = -2/6 = -10/30
BC = 4/5 = 24/30
AC + BC = 14/30 = 7/15
Answer is 7 and 7/15
