Answer:
A = 24 points
B = 12 Points
Step-by-step explanation:
Team A and team B play in a competition
Team A has 12 more points than team B
A = B + 12
Team A has twice as many points as team B
A = 2B
We substitute
2B = B + 12
2B - B = 12
B = 12 points
Solving for A
A = 2B
A = 2 × 12
A = 24 points

Mike 24 coins in nices and dimes they are valued at $2.05. how many DIMES does he have?
Answer: He has 8 dimes
Step-by-step explanation:
Answer:
17 dimes
7 nickels
Step-by-step explanation:
n = number of nickels
d = number of dimes
0.10d + 0.05n = 2.05
n + d = 24, n = 24 - d
substitute for n:
0.10d + 0.05(24 - d) = 2.05
simplify:
0.10d + 1.20 - 0.05d = 2.05
0.05d = 0.85
d = 17
n = 24-17 = 7

2. 3. Edward bikes the same route to and from school each day. After 28 school days, he bikes a total distance of 389.2 miles. a. Estimate how many miles he bikes in one day.
Answer:
Step-by-step explanation:
Estimate usually means "Don't use a calculator." An estimate would be 30 days and 390 miles. That makes 13 miles / day. I get the feeling that is not what is wanted.
miles / day = total distance / number of days
miles / day = 389.2 / 28
miles / day = 13.9 miles per day. I don't know which answer to use. I'd try this one first and then use the top one.

Which values for A and B will create infinitely many solutions for this system of equations? A x minus y = 8. 2 x + y = B.
Answer:
A = -2
B = -8
Step-by-step explanation:
A system of equations has infinitely many solutions when both equations are exactly the same equation, then both graphs intersect in infinitely many points, meaning that the system has infinitely many solutions.
Then if we have the equations:
A*x- y = 8
2*x + y = B
We want to find A and B such that both equations are exactly the same thing.
Notice that in the first one we have negative y, while in the second we have positive y.
Then A needs to be minus the coefficient that multiplies x in the other equation, this means that:
A = -2
And B needs to be minus the corresponding therm in the other equation, then B = -8.
Then the system becomes:
-2*x - y = 8
2*x + y = -8
We can see that one equation is -1 times the other, so if we write both of them as linear equations in the slope-intercept form, we get:
y = -8 - 2*x
y = -8 - 2*x
So both equations are exactly the same thing, meaning that we have infinitely many solutions.

Monthly grocery cost based on the average number of shopping trips is predicted using the least-square regression line, ŷ = 275.3 + 90.7x, where ŷ represents the predicted monthly expense and x represents the average number of trips. A shopper visits the grocery store an average of 3.2 times and has a monthly cost of $520. What is the residual for the shopper?
45.54
76.47
−45.54
−76.47
90.7
Answer:
−45.54
Step-by-step explanation:
Just took the test
The residual for the shopper will be equal to -45.54. Hence, option C is correct.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given data provided in the question,
The given equation is,
y = 275.3 + 90.7 x
Here, x is the number of trips and y is the total monthly expense.
Then,
Shopper monthly cost = $520
Number of visits by the shopper in a month = 3.2
So, the residual for the shopper will be,
$520 = 275.3 + 90.7 (3.2)
$520 = 275.3 + 290.24
= -45.54

In the graph shown below the y intercept is 0 so the coordinates of the vertical intercept would be (0,0)
When its asking for the horizontal intercept its asking " at what points does the equation cross the horizontal axis ( x axis ) so its pretty much asking for the x intercept."
In the graph shown below the x intercept is 0 so the coordinates of the horizontal intercept would be (0,0)
