Answer: £36
Step-by-step explanation: 10% is a tenth of the whole price (1/10). We would divide 40 by 10 to get 4 (1/10 of 40)- remember you divide by the bottom of the fraction and times by the top. To get the new price, we subtract 4 from 40 to get £36
How do I solve
-3x+y=24
-2x=+18+5y
Answer:
Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
18x−21y=24
−18x+10y=−2
Add the two equations.
−11y=22
Divide by -11 to isolate y.
y=−2
Substitute y=−2 into either of the 2 equations, I'll just use the second one.
9x+10=1
9x=−9
x=−1

Find the surface area of a cube
with side length 8.5 cm.
=========================================================
Explanation:
A cube has 6 identical faces, all of which are squares.
Each square has a side length of 8.5 cm, so its area is (8.5)^2 = 72.25 sq cm.
The overall surface area, aka the area of all 6 faces combined, is 6*72.25 = 433.5 square cm
Answer:
A=433.5cm²
Step-by-step explanation:
A=6a2=6·8.52=433.5cm²

Answer:
a = 57.5
b = 57.5
Step-by-step explanation:
XY=XZ so c=d
[tex]c = d = \frac{180 - 65}{2} = 57.5[/tex]
Now draw the XH
So angle YXH = 180 — 90 — 57.5 = 32.5
a+YXH=90
a+32.5=90
so a = 57.5
We know that a + 65 + b = 180
So 57.5 + 65 + b = 180
b = 180 — 122.5
b = 57.5

From the above diagram we can conclude that ~
Angle c = Angle a (Alternate interior Angle pair)
Angle d = Angle b (Alternate interior Angle pair)
and,
Angle c = Angle dbecause their opposite sides are equal.
now, according to linear pair property ~
Angle a + Angle b + 65° = 180°replacing Angle a with Angle c and Angle d with Angle b, because they are equal to one another ~
Angle c + Angle d + 65° = 180°2 × Angle c = 180° - 65°(because Angle c = Angle d)
2 × Angle c = 115°Angle c = 115° ÷ 2 Angle c = 57.5° = Angle dSo,
Angle a = Angle c = 57.5°Angle b = Angle d = 57.5°3 t-shirts cost £25.95.
How much do 10 t-shirts cost?

Answer:
£86.50
Step-by-step explanation:
To find how much 10 t-shirts cost we have to find how much they cost individually.
3 T- Shirts / 25.95 = 8.65 which means that each T-Shirt Costs 8.65.
8.65 x 10 T-Shirts = £86.50

One challenge of federalism is that
power and authority are concentrated in the central government and can take away people’s rights
sometimes officials from different levels of government disagree on who should be in charge of a situation
local governments have the most power, which creates problems for trade with other nations
officials from state governments have too many rules to follow to be effective leaders
Answer:
local governments have the most power
Step-by-step explanation:
I hope this is right, but federalism gives more power to the state, so local governments could potentially have more power.
Answer:
i believe it is option one: power and authority are concentrated in the central government and can take away people’s rights
Step-by-step explanation: well i mean its true the governments are corrupted and are slowly taking away our rights

Assume your phone bill averages $165 a month and you have a car payment that is $505 per month. You also spend about $150 a week on food. How much are your monthly expenses?
Answer:
1270 a month on expenses
Answer:
1270 a month
Step-by-step explanation:
There is 4 weeks for month so you multiply 150 x 4 = 600 and just add 165 and 505 which is equal to 1270
write the equation of a line parallel to 2x+3y=12 that passes through the point (-3,4)
Answer:
[tex]y = \frac{-2}{3}x + 2[/tex]
Step-by-step explanation:
The first step is convert the given equation in a dependent and independent equation.
[tex]2x + 3y = 12[/tex]
[tex]3y = 12 - 2x[/tex]
[tex]y = 4 - \frac{2}{3}x[/tex]
[tex]x[/tex] is the independent variable and [tex]y[/tex] the dependent variable.
Since both lines are parallel the slope of both equations are the same
[tex]y = \frac{-2}{3}x + b[/tex]
Now for find the unknow [tex]b[/tex] replace the [tex]x[/tex] and [tex]y[/tex] fo the given point.
[tex]4 = (\frac{2}{3})3 + b[/tex]
[tex]4 = 2 + b[/tex]
[tex]4 - 2 = b[/tex]
[tex]2 = b[/tex]
So the final equation is equal to
[tex]y = \frac{-2}{3}x + 2[/tex]

You rent an apartment that costs \$800$800 per month during the first year, but the rent is set to go up 9.5% per year. What would be the rent of the apartment during the 9th year of living in the apartment? Round to the nearest tenth (if necessary).\
Pls help I'm dying here
Answer:
Monthly rent for Year 9: $1,653.5
Total cost of rent for the whole 9th year: $19,841.9
Step-by-step explanation:
Given the monthly rent of $800 for an aparment, for which it is set to increase by 9.5% annually:
Increase in the Monthly Cost of RentYear 1:The monthly rent will stay at $800 for the first year.
Year 2:For year 2, we must add the 9.5% increase in the monthly rent. In order to determine the 9.5%, simply multiply the monthly rent by 0.095 (the decimal equivalent of 9.5%), then add the product to the monthly rent in year 1 of $800.
9.5% increase for Year 2: $800 × 0.095 = $76
Monthly rent in Year 2: $800 + $76 = $876
Year 3:For year 3, we must add the 9.5% increase in the monthly rent from Year 2 ($876).
9.5% increase for Year 3: $876 × 0.095 = $83.22
Monthly rent in Year 3: $876 + $83.22 = $959.22
Year 4:For year 4, we must add the 9.5% increase in the monthly rent from Year 3 ($959.22).
9.5% increase for Year 4: $959.22 × 0.095 = $91.13
Monthly rent in Year 4: $959.22 + $91.13 = $1,050.35
Year 5:For year 4, we must add the 9.5% increase in the monthly rent from Year 4 ($1,050.35).
9.5% increase for Year 5: $1,050.35 × 0.095 = $99.78
Monthly rent in Year 5: $1,050.35 + $99.78 = $1,150.13
Year 6:9.5% increase for Year 6: $1,150.13 × 0.095 = $109.26
Monthly rent in Year 6: $1,150.13 + $109.26 = $1,259.39
Year 7:9.5% increase for Year 7: $1,259.39 × 0.095 = $119.64
Monthly rent in Year 7: $1,259.39 + $119.64 = $1,379.03
Year 8:9.5% increase for Year 8: $1,379.03 × 0.095 = $131.00
Monthly rent in Year 8: $1,379.03 + $131.00 = $1,510.04
Year 9:9.5% increase for Year 9: $1,510.04 × 0.095 = $143.45
Monthly rent in Year 9: $1,510.04 + $143.45 = $1,653.50
Yearly Cost of Rent:In order to determine the yearly cost of renting an apartment, simply multiply monthly rent by 12. In other words:
Year 1: $800 × 12 = $9600
Year 2: $876 × 12 = $10,512
Year 3: $959.22 × 12 = $11,510.64
Year 4: $1,050.35 × 12 = $12,604.15
Year 5: $1,150.13 × 12 = $13,801.55
Year 6: $1,259.39 × 12 = $15,112.69
Year 7: $1,379.03 × 12 = $16,548.40
Year 8: $1,510.04 × 12 = $18,120.50
Year 9: $1,653.50 × 12 = $19,841.94
Therefore, due to the 9.5% annual increase in rent, the monthly cost of an apartment during the 9th year is $1,653.5, or $19,841.9 (12-months' worth of rent).

the length of a rectangle is 5 less than 2 times its width, if the perimeter is 86ft, what is the length and width of the rectangle. Write and solve the equation
Answer:
Width: 16
Length: 27
Step-by-step explanation:
Let x be the width of the rectangle.
The length would then be 2x - 5
The perimeter is:
2x - 5 + x + 2x - 5 + x =
6x - 10 = 86
Solve.
6x = 96
x = 16
Thus,
Width: 16
Length: 27
the midpoint of (3 x, -2) and (-4, 5y) is (1,4). find x, -y
Answer:
(x,-y): (2,-2)
Step-by-step explanation:
M=(x+x)/2,(y+y)/2
Given (1,4)=
[tex] \frac{3x - 4}{2} [/tex]
This implies:
[tex]1 = \frac{3x - 4}{2} [/tex]
[tex]3x - 4 = 2 \\ 3x = 2 + 4 \\ \frac{3x }{3} = \frac{6}{3} \\ x = 2[/tex]
In a similar way,
[tex]4 = \frac{ - 2 + 5y}{2} \\ - 2 + 5y = 8 \\ 5y = 10 \\ y = 2[/tex]
The question demanded (x,-y)
Hence(2,-2) is the answer
