Answer:
20/5 = 4, the slope is 4
Step-by-step explanation:
I wouldn't use the dotted red line for rise/run since it does not cross at a whole number, I would use the origin (0,0), and (5,20) since those seem to cross perfectly on the lines, so the slope is rise/run = 20/5 or 4/1 or 4

Answer:
0.45
Step-by-step explanation:
Since the percent to pull a ball with a 2 is 30% and the percent to pull a ball with a 4 is 15%, that means that the chance of pulling a ball with an even number is 0.45, or 45%. (0.30+0.15=0.45)

Carly made $10 in interest by placing $500 in a savings account with simple interest for 1 year. What was the interest rate?
Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answers
Answer:
2% or 0.02
Step-by-step explanation:
I=prt
10=500*x*1
10=500x
divide 500 by both sides
rate=0.02 or 2%

Chris and Eric are competing on a game show. Together they answer 22 questions correctly. Chris’ score was 8 less than twice Eric’s score. How many did each of the guys answer correctly?
Answers
Answer:
eric = 15
chris 7
Step-by-step explanation:
Let the questions Chris answered correctly be represented by c
Let the questions Eric answered correctly be represented by e
They both got 22 questions right. This can be represented by this equation :
c + e = 22 --- eqn 1
Chris scored 8 less than Eric. This can be represented by this equation :
c = e - 8 --- eqn 2
Substitute for c in eqn 1
e - 8 + e = 22 .
collect like terms
2e = 30
solve for e
e = 15
Substitute for e in eqn 2
c = 15 - 8 = 7
Find the distance between (1,1) and (13,6)
Answers
Explanation:
13 - 1 = 12
6 - 1 = 5
Hope this helps!
Answer:
The distance is 13 units
Step-by-step explanation:
13 - 1 = 12
6 - 1 = 5
12² + 5² = c²
144 + 25 = c²
√169 = c
c = 13
(I could have used the distance formula, but the pythagorean theorem is shorter for this problem)

HOPE IT HELPED YOUA city bus collected $1,140 in fares on a given day. The regular fare is $1.50, and the reduced fare is $0.75. If 1,042 total fares were paid, which system of linear equations can be used to find x, the number of regular fares paid, and y, the number of reduced fares paid?
Answers
Answer:
x + y = 1042
1.50x + 0.75y = 1140
Step-by-step explanation:
If there was a total of 1,042 fares paid then x + y would be equal to that because x is the number of regular fares paid and y is the number of reduced fares paid.
If there was a total of $1,140 made from the fares then we can use 1.50x + 0.75y. We put the 1.5 in front of the x because each fare paid costs $1.50, same with Y each reduced fare paid is $0.75. So both of those need to be added up to get $1,140.
