Answer:
Gordon gets £72
Step-by-step explanation:
£240....together
Sara.....2*(3x)
Gordon.....3x
Makachy......x
2*(3x)+3x+x=240
6x+3x+x= 240
10x=240/10
x=24
Gordon 3*24= 72
Total is 61.36 not sure how much she should leave for tip
Answer:
Hello sorry I don't know the history questions but I do know this one! answer: b 5/36
Step-by-step explanation:
The answer is B because the probability of picking a red is 5/12 and for white it is 4/12 and then we multiply these 5/12 × 4/12 = 5/36 so 5/36 is the probability of getting red, white hope this helps!
Remark
This is a very interesting question. Draw a line from the origin to where the upper right vertex of the square touches the line. That line has the property that the its equation is y = x. So the "solution" to the point of intersection is the solution of the two equations.
y = x (1)
3x + 4y = 12 (2)
Put x in for y in equation 2
3x + 4x = 12
7x = 12
x = 12/7
x = 1.714
y = 1.714
Problem A
<em><u>x intercept</u></em>
The x intercept occurs when y = 0
3x + 4(0) = 12
3x = 12 Divide by 3
x = 12/3
x = 4
the x intercept = (4,0)
<em><u>y intercept</u></em>
The y intercept occurs when x =0
3(0) + 4y = 12
4y = 12
y = 12/4
y = 3
y intercept = (0,3)
Problem B
x and y both equal 1.714 so they are also the length of the square's side.
Problem C
See solution above. x =y is the key fact.
x = y = 1.714
Answer:
The solution to the system of equations is:
The graph is attached below.
Step-by-step explanation:
Given the system of equations
Let us solve the system of equations using the elimination method
Arrange equation variables for elimination
Multiply y + 2x = 5 by 2: 2y + 4x = 10
subtracting the equations
solve 6x = 18 for x
Divide both sides by 6
simplify
For 2y - 2x = -8 plug in x = 3
Add 6 to both sides
Simplify
Divide both sides by 2
Simplify
Therefore, the solution to the system of equations is:
The graph is attached below.
