Answer:
y = 15x
Step-by-step explanation:
Given x and y are in direct variation then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 2, y = 30, then
30 = 2k ( divide both sides by 2 )
15 = k
y = 15x ← equation of variation

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:

Answer:
The answer is A.) a credit
Step-by-step explanation:
I hope this helps!
Answer:
If you ask a banker whether debiting or crediting a liability increases the account’s balance, the financier will tell you it depends on the transaction. The same answer holds true for accounting procedures, even though banking debits and credits are distinct from accounting practices. To understand the effects of journal entries on financial accounts, it’s important to master such terms as liability, record keeping and financial reporting.

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
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

pls help if u can
thanks in advance
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
Which table matches 4x+7y=19?
Answer:
c
Step-by-step explanation:
The table which matches 4x + 7y = 19 is table (d).
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Given is a linear equation,
4x + 7y = 19
(a) When x = -18,
7y = 19 - (4 × -18) = 91 ⇒ y = 13
When x = 1,
7y = 15 ⇒ y = 2.14
So the table (a) is not the one.
(b) When x = -9, 7y = 55, y = 7.857
Table (b) is also not the one.
(c) When x = 0, y = 2.7
Hence (c) is also not an option.
(d) When x = -18, y = 13
When x = -11, 7y = 63, y = 9
When x = -4, 7y = 35, y = 5
So the correct option is table (d).
Hence the correct option is table (d).

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

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

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.
