Answer:
75
Step-by-step explanation:
Crazy cakes makes wedding cakes and birthday cakes. One week they made 2 wedding cakes and 5 birthday cakes and made $500. The next week they made 1 wedding cake and 7 birthday cakes but only made $430. What is the cost of a wedding cake? What is the cost of a birthday cake?
Answer:
Cost of Wedding cakes = x = $150
Cost of Birthday cakes = y = $40
Step-by-step explanation:
Let us represent:
Cost of Wedding cakes = x
Cost of Birthday cakes = y
Crazy cakes makes wedding cakes and birthday cakes. One week they made 2 wedding cakes and 5 birthday cakes and made $500.
2x + 5y = 500..... Equation 1
The next week they made 1 wedding cake and 7 birthday cakes but only made $430.
x + 7y = 430..... Equation 2
x = 430 - 7y
We substitute 430 - 7y for x in Equation 1
2x + 5y = 500..... Equation 1
2(430 - 7y ) + 5y = 500
860 - 14y + 5y = 500
860 - 500 = 14y - 5y
360 = 9y
y = 360/9
y = $40
Solving for x
x = 430 - 7y
x = 430 - 7(40)
x = 430 - 280
x = $150
Therefore:
Cost of Wedding cakes = x = $150
Cost of Birthday cakes = y = $40
$100 into a savings account that earns 6% annual intrest compounded monthly for 5 years
Answer:
$141.94
Step-by-step explanation:
Basically multiply 100 by .06, add the answer too 100. Which gets 106.
Multiply 106 by .06 and add the answer to 106, do that 5 times(which counts as the five years) and vuala, you got your answer.
And since it said an annual
interest, then the monthly compounding doesn't matter.

Write the equation of the line, in slope-intercept form, that has a slope of -8/5and contains the point
Answer:
y = -8/5x + 23/5
Step-by-step explanation:
Complete question
Write the equation of the line, in slope-intercept form, that has a slope of -8/5and contains the point (6, –5)
The equation of a line in pint slope form is expressed as;
y - y0 = m(x-x0)
Given
m = -8/5
(x0, y0) = (6, -5)
Substitute into the formula
y - (-5) = -8/5(x-6)
y+5 = -8/5(x-6)
Multiply through by 5
5(y+5) = -8(x-6)
5y + 25 = -8x + 48
5y = -8x +48 - 25
5y = -8x + 23
y = -8/5x + 23/5
Hence the equation in slope intercept form is y = -8/5x + 23/5

Which list shows the integers in order from lest to greatest ? -8 , -5 , 0 , 2 , 6 0 , 2 , -5 , 6 , -8 -5 , -8 , 0 , 2 , 6 0 , -8 , -5 , 2 , 6
Answer:
a.-8,-5,0,2,6
Step-by-step explanation:
We have to find the list which shows the integers in order from least to greatest.
We know that when we left side of zero on a number line then the values decrease and we go right side of zero then the value increases.
a.-8,-5,0,2,6
-8<-5<0<2<6
Hence, it is true.
b.0,2,-5,6,-8
-8 least and 6 is greatest
Therefore, it is false.
c.-5,-8,0,2,6
It is false.
d.0,-8,-5,2,6
It is false.
Option a is true,

y=9/8
What does y stand for in math
Answer:
The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair of coordinates (x,y) such as (12,5). In this example, the value "5" is the Y Coordinate. Also called "Ordinate"
Step-by-step explanation:
Answer:
In math a letter is always a variable. If you are solving an equation and the letter y is there you have to solve for y. So in math y stands for a variable.

2/5 of a number is 40. What is 1/10 of the number
Please help me
Answer:
10
Step-by-step explanation:
Answer:
1/10 of the number is 10.
Step-by-step explanation:
We know that 40 is 2/5 of this unknown number, so 4/5 would be 80. Then, to fill up the other 1/5, we must split 40 into half.
1/2 of the number 40 is equal to the number 20.
80 + 20 = 100, so 5/5 would be equal to 100.
Now, we have to find one tenth of the number 100.
1/10 of the number 100 is the number 10. (1/10 of 100 = 10)
The answer to the question is 10.

Sean paints 8/15 of a fence in 1 hour. He paints 3/10 of the fence less in the second hour. What fraction of the fence did he paint in two hours? Did he finish the job in two hours?
Answer: [tex]\frac{3}{10}[/tex]
Step-by-step explanation:
Given
Sean paints [tex]\frac{8}{15}[/tex] of a fence in 1 hour
Sean paints [tex]\frac{3}{10}[/tex] part less in the second hour
So, fraction he paints in the second hour = [tex]\frac{8}{15}-\frac{3}{10}=\frac{16-9}{30}=\frac{7}{30}[/tex]
Paint in 2 hours = [tex]\frac{8}{15}+\frac{7}{30}=\frac{16-7}{30}=\frac{9}{30}[/tex]
=[tex]\frac{3}{10}[/tex]
No, he did not finish his job

Which two points are on the graph of y=x+3?
Answer:
(0, 3) and (-3, 0) are just two out of an infinite number of other points
Step-by-step explanation:
I found these 2 points by plugging in 0 for x and y would equal 3
Then I plugged in 0 for y and x would equal -3
i need to find the slope from two points i don’t know how to do this!show work please
Answer:
2
Step-by-step explanation:
Ok, so they gave you these two points, since I can't actually graph it, then we can just make a table...
x y
4 6
6 10
From 6 to 10, you add 4 (this is for the y section)
From 4 to 6 you add 2 (this is for the x section)
Now you need to divide the y by the x....
y/x = 4/2 = 2
And 2 will be the answer for your slope, given these 2 points.
Hope this helped!

Helpp!! Determine whether the lines are parallel, perpendicular, or neither. 2x−10y=14 and y=−5x+9. Show work
Pleasee help meee
Answer:
Perpendicular
Step-by-step explanation:
2x-10y=14
-2x -2x
-10y=14-2x
/-10 /-10
y=14+1/5
in order for them to be perpendicular the slope has to be the complete opposite to be more exact the number has to be flipped and so does the sign and since -5 was flipped to +1/5 it shows that they would be perpendicular

Find the set of values of x for which x^2-x-6>0 and 10-2x<5
Answer:
No Solution.
Step-by-step explanation:
For starters, here are our two equations:
[tex](x^2-x-6)>0[/tex]
[tex]10-2x<5[/tex]
The first option is to solve for x in our second equation. First, we add 2x to both sides to get [tex]10<5+2x[/tex]. Then, we subtract 5 from both sides to get [tex]2x<5[/tex]. Finally, we divide both sides by 2 to get [tex]x<2.5[/tex]. We can plug in 2.5 into our second equation to test if it works. If it does not work, then anything less than 2.5 won't work, and the solution would be impossible.
Now we can plug in our values into our first equation. We now have the equation [tex]2.5^2-2.5-6>0[/tex]. We can simplify to get [tex]-2.25>0[/tex]. This test failed, so there are no solutions. A solution would be impossible.

Step-by-step explanation:
Solve for x: -4x - 12 < 12
Seems like you are an imposter ;). This is Middle School math.
Anyways...
Answer:
x>6
Step-by-step explanation:
-4x-12<12
Add 12 on both sides.
-4x<24
Divide both sides by -4 to isolate x. Remember that if you are dividing by a negative, flip the sign!
x>6
