Answer: 17/7
Step-by-step explanation: Step 1: Simplify both sides of the equation. y+4/15 + 2y−5/5 = 2/5 1/15 y+ 4/15 + 2/5 y+−1= 2/5 (Distribute) ( 1/15 y+ 2/5 y)+( 4/15 +−1)= 2/5 (Combine Like Terms) 7/15 y+ −11/15 = 2/5 7/15 y+ −11/15 = 2/5 Step 2: Add 11/15 to both sides. 7/15 y+ −11/15 + 11/15 = 2/5 + 11/15 7 15 y= 17/15

Please help!
Answer:
-4
Step-by-step explanation:
7 + (-11) basically translates to 7 - 11. Since the bigger number has the negative sign here, you just have to subtract 11-7 and then add the negative onto the answer.

6-2x=y 14+3x=y plzzz helllllllllllllllp
Answer:
(- [tex]\frac{8}{5}[/tex], [tex]\frac{46}{5}[/tex] )
Step-by-step explanation:
Given the2 equations
6 - 2x = y → (1)
14 + 3x = y → (2)
Substitute y = 14 + 3x into (1)
6 - 2x = 14 + 3x ( subtract 3x from both sides )
6 - 5x = 14 ( subtract 6 from both sides )
- 5x = 8 ( divide both sides by - 5 )
x = - [tex]\frac{8}{5}[/tex]
Substitute x = - [tex]\frac{8}{5}[/tex] into either of the 2 equations for the corresponding value of y
Substituting into (1)
y = 6 - 2(- [tex]\frac{8}{5}[/tex] ) = [tex]\frac{30}{5}[/tex] + [tex]\frac{16}{5}[/tex] = [tex]\frac{46}{5}[/tex]
solution is ( - [tex]\frac{8}{5}[/tex], [tex]\frac{46}{5}[/tex] )
Lilly babysits for $10 per hour. She works for 5 hours. She uses her money to buy a new sweater that cost $20.
How much money will Lilly have left?
Answer:
30 dollars left
Step-by-step explanation:
If Lily works for 10 dollars per hour and works 5 hours which adds up to 50 dollars then she buys a sweater for 20 so 50 minus 20 is 30 dollars, so Lily has 30 dollars left over.
Line q passes through the point (4,6)and (0,6).
Answer:
The equation of the line passing through the points (4, 6) and (0, 6) will be:
y = 6The graph of the equation y = 6 is also attached.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the points
(4, 6)(0, 6)Finding the slope between (4, 6)and (0, 6).
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [6 - 6] / [0 - 4]
= 0 / -4
= 0
Thus, the slope of the line = m = 0
The slope m = 0 means the line is horizontal. Because the slope of the horizontal line is 0.
As the y-values are not changing with respect to the x-values.
Therefore,
The equation of the line passing through the points (4, 6) and (0, 6) will be:
y = 6The graph of the equation y = 6 is also attached.
Each hexagon tile has an area of LaTeX: 18\sqrt{3} 18 3 in.2 . Solve for x. Then find the exact length of each side of the hexagon. (Hint: Six equilateral triangles make one hexagon.)
Answer:
The length of the side of the hexagon is [tex]2\sqrt{3}[/tex] inches.
Step-by-step explanation:
According to this question, we have a regular hexagon with a surface area of [tex]18\sqrt{3}\,in^{2}[/tex]. From Geometry, we know that all regular hexagons can be formed by six regular triangles, since the angle of one complete revolution (360º) divided by the number of triangles is equal to the internal angle of each triangle (60º). Then, the area of each triangle is found after dividing the complete area by the number of regular triangles:
[tex]A_{\triangle} = \frac{18\sqrt{3}\,in^{2}}{6}[/tex]
[tex]A_{\triangle} = 3\sqrt{3}\,in^{2}[/tex]
The area of the triangle as a function of the length of the side of the hexagon ([tex]l[/tex]), measured in inches, is determined by this equation:
[tex]A_{\triangle} = \frac{\sqrt{3}}{4} \cdot l^{2}[/tex] (1)
If we know that [tex]A_{\triangle} = 3\sqrt{3}\,in^{2}[/tex], then the length of the side of the hexagon is:
[tex]\frac{4}{\sqrt{3}}\cdot A_{\triangle} = l^{2}[/tex]
[tex]l^{2} = \frac{4\cdot \sqrt{3}}{3} \cdot A_{\triangle}[/tex]
[tex]l = 2\sqrt{\frac{\sqrt{3}}{3}\cdot A_{\triangle} }[/tex]
[tex]l = 2\sqrt{3}\,in[/tex]
The length of the side of the hexagon is [tex]2\sqrt{3}[/tex] inches.

Find the measurement of angle A & B
Answer:
Angle A = 65
Angle B = 78
Step-by-step explanation:
This is a triangle, and the total angles in a triangle is 180 degrees. What you can do is make all of the angles equal 180 and then solve for x.
180 = (2x +4) + (2x - 9) + x
180 = 2x +4 + 2x - 9 + x
180 = 4x -5 +x
180 = 5x - 5
185 = 5x
37 = x
Now, plug in x to solve for the angles.
Angle A = 2(37) - 9 = 65 Angle B = 2(37) + 4 = 78Angle C = x = 37
Investors buy a studio apartment for $240,000. Of this amount, they have a down payment of
$36,000. Their down payment is what percent of the purchase price? What percent of the purchase
price would a $12,000 down payment be?
Answer:
The down payment of $36000 is 15% of price.The down payment of $12000 is 5% of price.Step-by-step explanation:
Given that
Price of studio apartment = P = $240000
Down payment =d = $36000
Down payment is the amount that is initially given at the time of buying something.
Part A: For down payment of $36000
We will simply divide the down payment by total price.
[tex]= \frac{36000}{240000}\\=0.15[/tex]
Converting into percentage, multiplying by 100
[tex]= 0.15*100 = 15\%[/tex]
Part B: For down payment of $12000
We will simply divide the down payment by total price.
[tex]=\frac{12000}{240000}\\=0.05[/tex]
Converting into percentage, multiplying by 100
[tex]=0.05*100 = 5\%[/tex]
Hence,
The down payment of $36000 is 15% of price.The down payment of $12000 is 5% of price.what is the slope of the line -9x + 7y = 63

16. Find the value of y.
y + (2x -12) = 180 (since they are supplementary angles)
(2x-12) = 96 ( since they are alternate exterior angle)
2x = 96 + 12
2x = 108
x = 108/2
x = 54.
y+( 2x-12)=180
y+(2× 54 -12) = 180
y + (108-12) = 180
y + 96 = 180
y= 180-96
y = 84.
5x + 4y = 17
Y - x = 2
x =
y =

You have a bag of 15 marbles. 8 are red. 5 are blue. 2 are green. You asked 15 people to pull a random marble and replace it. The outcome was that 10 got red, 4 got blue and 1 got green. Joe thinks if 15 more people try 8 will pull red. Jill thinks if 15 more people try 10 will pull red. Choose the most accurate statement.
a
Joe is right because the theoretical probability is better.
b
Jill is right because the experimental probability is better.
c
We don't know what will happen, but both Joe and Jane are making good, educated assumptions.
d
We don't know what will happen because anything is possible and there is not point in calculating probabilities. Whatever happens, happens.
e
6 people will pull red to average out to 8. The long term average must match the theoretical probability.
Answer:
C.
Step-by-step explanation:
We have 2 probabilities: Theoretical probability and Experimental probability.
We cant know what will happen as it's just probability but both joe and Jill are making educated guesses based on probabilities, just different kinds.
