Answer:

c

Step-by-step explanation:

The table which matches 4x + 7y = 19 is table (d).

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).

Step-by-step explanation:

Answer:

(x, y) = (23, 4)

Step-by-step explanation:

2x - 5y = 26

x - 5y = 3 $\Rightarrow$ x = 3+5y

substituting the value of x ( second equation) into the first equation, we get, 2(3+5y) - 5y = 26. Simplifing, we get,

6+10y - 5y =26

5y = 20

y = 4

So, x = 3+5*4 = 3+20 = 23

Answer:

[tex]\left \{ {{x=23} \atop {y=4}} \right.[/tex]

Step-by-step explanation:

[tex]\left \{ {{2x - 5y =26} \atop {x-5y=3}} \right.[/tex]

you can add 5y to both sides of the second equation:

[tex]x = 5y + 3[/tex]

Then, substitute:

[tex]2(5y + 3) - 5y = 26[/tex]

use the distributive property on the left side:

[tex]10y + 6 - 5y = 26[/tex]

[tex]5y + 6 = 26[/tex]

subtract 6 from both sides

[tex]5y = 20[/tex]

divide both sides by 5

[tex]y = 4[/tex]

Substitute into original equation

[tex]x - 5y = 3 --> x - 5(4) = 3\\x - 20 = 3\\x = 23[/tex]

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

Answer:

She started with 50 stamps

Step-by-step explanation:

Hi! For these types of problems we always result to going backwards. So, she now has 30 right? So, to reverse into the problem, we do the opposite of what it says. "She then bought five more" 30 - 5 = 25. Then it says she sold half of them. 25 x 2 = 50. If we recheck by going back, she sold half of them (50 / 2 = 25) and she bought five more (25 + 5 = 30).

Answer:

1) The amount to be paid as insurance if the revenue increases is $937,000

2) Yes because the total value of the risk insured and the likelihood of the occurrence of the risk both increases

Step-by-step explanation:

1) The given amount in revenue of the Diablo's Domain = $250,000,000

The amount the company paid as insurance  = $750,000

The equivalent amount the company paid as insurance = $3 for every $1,000

The percentage amount in revenue the park revenue increases by = 25%

Therefore, the new amount in revenue = 1.25 × $250,000,000 = $312,500,000

The amount to be paid as insurance if the revenue increases = $315,500,000 × 3/1000 = $937,5000

The amount to be paid as insurance if the revenue increases = $937,000

2) It is reasonable for the insurance cost to increase proportionally when the items insured which leads to the increase in revenue increases because the value of the risk insured which is the event of settlement for losses increases as well as the probability of the risk occurring also increases.

Answer: 65

Step-by-step explanation:

P = 2L + 2w   <---- formula for perimeter

26 = 2L + 2w  <--- original perimeter is 26

13 = L + w <--- divides everything by 2

32.5 = 2.5L + 2.5w <-- scale factor of 2.5; those are the NEW length and width

Multiplying both sides by 2, the new perimeter is 65;

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

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.

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.

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.
