Answer:
Wyatt played 3 games and went on 6 Rides
Step-by-step explanation:
Let games be represented as x
Let ride be represented as y
Each game cost $1.25
Each ride cost $2.75
Total money spent by Wyatt= $20.25
x1.25 + y2.75 = 20.25 ..... Equation 1
the number of rides he went on is twice the number of games he played
Y= 2x ... Equation 2
Substituting the value of y into equation 1
x1.25 + y2.75 = 20.25
x1.25 + 2(x)2.75 = 20.25
x1.25 + x5.5 = 20.25
x6.75= 20.25
x= 20.25/6.75
X= 3
Y= 2x
Y= 2(3)
Y= 6
Wyatt played 3 games and went on 6 Rides

Jaxon was asked 40 questions on a test he answered 80% incorrectly how many did he get correct
Answer:
8 correct.
Step-by-step explanation:
80 / 100 = x / 40 (Since he got 80% INCORRECT you will subtract the value of x from 40)
100x = 80 x 40
x = 3200 / 100
x = 32
40 - 32 = 8

Answer:C
Step-by-step explanation:
The derivation of the quadratic function is true
What is Quadratic Equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
ax² + bx + c = 0
Step 1 :
ax² + bx + c = 0
Step 2 : Subtracting c on both sides , we get
ax² + bx = -c
Step 3 : Divide by x on both sides , we get
ax + b = -c/x
Hence , the steps are true in solving the quadratic equation

When = 3, what will the value for y be for the equation - 4x + 5y = 18?
If x equals 3 then y must equal 1.2
Answer: y=6
-4(3)+5y=18
-12+5y=18
add 12 to both sides
-12+5y+12=18+12
5y=18+12
5y=30
divide both sides by 5
5y÷5=30÷5
y=30÷5
y=6

Answer:
PQ=30
Step-by-step explanation:
Knowing that the segment has 3 parts that are 3:1:1 and sum up to 50, you could find how much 1 would equal by finding the total in relation to the ratio (doing 3+1+1) which gets you 5 parts. Then you can divide the total (50) by 5 to figure out how much one part would equal (10). Now, since you know that 1 part is equal to 10 and that PQ is 3 parts, you can find that PQ is equal to 3x10, or 30.
Mario walked at a rate of 5/6 miles every 10 minutes what is his unit rate every mile per hour
Answer:
Mario's unit rate is 5/1
Step-by-step explanation:
We know that Mario walks 5/6 miles per 10 minutes.
We need to find out how many miles Mario walks in 60 minutes (1 hour).
10 * 6 = 60. Which means that we must multiply 5/6 by 6.
[tex]\frac{5}{6} *\frac{6}{1} = \frac{30}6[/tex]
30/6 = 5
Mario walks 5 miles per hour.
To put this in to a unit rate we must put this is a fraction:
[tex]\frac{Miles}{Hour}[/tex]
Substitute:
5/1
Answer:
Mario's unit rate is given by 900 miles/hour
Step-by-step explanation:
We have been given that Mario walked at a rate of 2/3 miles every 10 minutes
We have the relation between speed, time and distance, which is given by
speed = distance/Time
we have,
distance = 2/3 miles
Time = 10 minutes
On substituting these values in above formula, we got
speed 2/3 /10
speed 2/10.3
We have to find the unit rate in mile per hour, so we need to multiply it by 60
Thus, unit rate is given by
1/15 X 60
= 4 miles/hour
This table represents the number of ounces, u, a kitten grows after w, weeks. When graphed, all of the points in the table lie on the same line. What is the slope and y-intercept of the line? slope=−23, y-intercept=−0.2 slope=32, y-intercept = 3 slope=23, y-intercept=−0.2 slope=−32, y-intercept = 3
Using the slope and intercept formula, the slope and y - intercept values of the graphed data are 3/2 and 3 respectively
Given the data :
Weeks, w ___ Weight in ounces, u
0 __________ 3
3 _________ 7.5
6 __________12
9 _________16.5
The y - intercept :
This is the value of y when the value of x = 0From the table given, the initial weight of the kitten (weight at week 0) = 3 ounces
Hence, the intercept is 3 ounces.
2.)
The slope :
Slope = Rise / RunRise = y2 - y1 = (16.5 - 3) = 13.5
Run = x2 - x1 = 9 - 0 = 9
Slope = 13.5 / 9 = 1.5
Therefore, the slope is 1.5
