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?
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

A 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?
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.
Factor y =`x^{2}\ +\ 3x\ -\ 10`

The middle number is -9 and the last number is 8.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -9
Multiply together to get 8
Can you think of the two numbers?
Try -1 and -8:
-1+-8 = -9
-1*-8 = 8
Fill in the blanks in
(x+_)(x+_)
with -1 and -8 to get...

15. Let's solve your equation step-by-step.
(x−2)(x−3)=2
Step 1: Simplify both sides of the equation.
x2−5x+6=2
Step 2: Subtract 2 from both sides.
x2−5x+6−2=2−2
x2−5x+4=0
Step 3: Factor left side of equation.
(x−1)(x−4)=0
Step 4: Set factors equal to 0.
x−1=0 or x−4=0
x=1 or x=4

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.
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%

b) .30
c) .45
d) .50
Answer:
0.45
Step-by-step explanation:
