Two pencils and a ruler cost 98 cents in total. One pencil and 2 rulers cost $1.24 in total. Find the cost of each item.
Answer:
2.16
Step-by-step explanation:
r = cost of ruler
p = cost of pencil
r = 2p
6r + 15p = 2.16
Substitute 2p in place of r in 2nd equation and solve for p
6(2p) + 15p = 2.16
12p + 15p = 2.16
27p = 2.16

MN = TS
5x -2 = 3x + 1
Add 2 to both sides:
5x = 3x + 3
Subtract 3x from both sides:
2x = 3
Divide both sides by 2
X = 3/2
Now you have x solve for TS
TS = 3x + 1 = 3(3/2) + 1 = 4 1/2 + 1 = 5 and 1/2

Step-by-step explanation:
☆Remember:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆Just plug it in with 2 sets of coordinate points.

A company made 1,215 yards of copper wire.
They want to wrap the same amount of wire on each three poles.
3 poles = 1,215 yards of copper wire
1 pole = 405 yards of copper wire
So, each pole will require 405 yards of copper wire.
pls help if u can

Answer:
x=55
Step-by-step explanation:
Since the two lines are parallel the two angles are same side exterior. This means their sum is 180. So to solve put them equal to 180, x+9+2x+6=180.
First, combine like terms
3x+15=180
Then, subtract 15 from both sides
3x=165
Finally, divide the entire equation by 3
x=55

The combined ages of megan and kyle are 27. if kyle is twice as old as megan, how old is kyle.
kyle is 18 and megan is 9, because 9 + 18 = 27 and 27 / 3 = 9. hope this helps :)
Answer:
Kyle's age = 18 years
Step-by-step explanation:
Let Megan's age = x
Kyle's age = 2x
Combined ages of Megan and Kyle = 27
x + 2x = 27
3x = 27 {Divide both sides by 3}
3x/3 = 27/3
x = 9
Megan's age = 9 years
Kyle's age = 2 * 9 = 18 years

Answer:
A: ∠W'Z'Y' = 60°; angles aren't changed by rotation
B: W'(-3, 6), X'(9, 6), Y'(8, 1), Z'(-4, 1)
Step-by-step explanation:
Part A:
Angle WZY is the supplement of the given angle ZWX, so is ...
∠WZY = 180° -120° = 60°
Rotation about the origin (or anywhere else) does not change angles. The new parallelogram will have ...
∠W'Z'Y' = 60°
__
Part B:
The transformation right 2 and up 3 can be described by ...
(x, y) ⇒ (x +2, y +3)
Then the translated vertices are ...
W(-5, 3) ⇒ W'(-3, 6)
X(7, 3) ⇒ X'(9, 6)
Y(6, -2) ⇒ Y'(8, 1)
Z(-6, -2) ⇒ Z'(-4, 1)

The cost price of an electronic fan is Rs 2,800. If the shopkeeper marks its price
30% above the cost price and sells it at 10 % discount, how much should a
customer pay for it with 15 % VAT?
Answer:
cp=2800
mp=cp+30%of cp=2800+30/100×2800=3640
discount=10%
discount amount=10%ofmp=10/100×3640=364
sp=mp-discount=3640-364=3276
vat=15%
sp with vat=sp+vat%of sp=3276+15/100×3276=3276+491.4=3767.40
The price customers pay for it with 15 % VAT is Rs 3767.40 if the cost price of an electronic fan is Rs 2,800.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
The cost price of an electronic fan is Rs 2,800.
Cost with 30% above the cost price = Cost price +30% of cost price
= 2800 + (30×2800)/100
= 3640
Discount = 10%
Discount amount = 10% of 3640 = 364
Discounted price = 3640 - 364 = 3276
VAT = 15%
Discounted price with VAT = 3276 + 15% of 3276
= 3767.40
Thus, the price customers pay for it with 15 % VAT is Rs 3767.40 if the cost price of an electronic fan is Rs 2,800.

What is the the translation rule
Please answer me .....
Answer:
a. 2x -3
b. 7
Step-by-step explanation:
a. The expression that represents the difference is sales between the two sales will be:
9x - (7x + 3) = 9x - 7x - 3 = 2x - 3
b. What we do here is to simply substitute the value of 5 for x
mathematically, we have to substitute the value of 5 in the expression above
We have this as:
2(5) -3
= 10-3 = 7
Solve the system.... 2y+8x+58 and y-5x=11
Answer:
x=2, y=21
Step-by-step explanation:
there are two methods: substiution and elimation. I will be doing subtistution in this soultion:
first isolate y in either equation, it would be easier to do it in the second one.
y= 11+5x
Then, subtitute that into the first equation
2(11+5x)+8x=58 (it says 2y+8x+58 but I assume you mean 2y+8x=58?)
22+10x+8x=58
18x = 36
x=2
substitute that back into y = 11+5x, to get y=11+10 = 21
