7x — 2 = 5x + 14​

Answer:

Yes

Step-by-step explanation:

a^2+b^2=c^2

7^2+11^2=c^2

49+121=c^2

170=c^2

then square it

c=13

7,11,13 is a pythagorean triple

Answer:

both answers you have put in are correct

Step-by-step explanation:

7^2=49

11^2=121

121+49=170

square root of 170 is the long side

not a pythagorean triple because square root of 170 does not come out as a whole number (no decimal/fraction)

is it ~13.0384

Answer:

$16.54

Step-by-step explanation:

First step we need to do is to find the bill without the 15% tips:

95.11 = 1.15x

x = $82.70 is the original bill

Now we can add the 20% tips and multiply it into the original:

82.70 x 1.2 = $99.24 is the new bill

To find out how much you tipped:

99.24 - 82.7 = $16.54 is your new tip

Answer: Atleast 7

Step-by-step explanation:

In order to make a profit you have to amke more money than what you spent for supplies. So if each shirt is 10$ then you would have to sell atleast 7 shirts since if you do you will have made 70$, therefore a 10$ profit. If you sell 6 shirts, you make 60$, meaning you gain all your money back, but you do not make a profit.

the answer is 7

Step-by-step explanation:

7×10=70-60=10

Answer:

d. -4 <= x - 5

Step-by-step explanation:

I think youre asking about question 5.

First replace the x with the -2 in every problem.

Now solve:

a. 6 × -2 < 10

6 times -2 is -12, and -12 is less than -10, so that ones true and not the answer

b. -2 × -2 > -3

-2 times -2 is 4, and 4 is greater than -3, so that ones true and not the answer

c. -2/4 <= 0

-2 divided by 4 is -1/2, and -1/2 is less than 0. so that ones true and not the answer

So obviously the answers d, but we're gonna check anyway

d. -4 <= -2 - 5

-2 minus 5 is -7, and -7 is not less than -4, so its not true and the answer

Answer:

No solution

Step-by-step explanation:

There are no values of  x  that make the equation true.

Answer:

B= -3

Step-by-step explanation:

So first distribute what you can

12b+2=4b-20-2

Now combine like terms

12b+2=4b-22

Now subtract 2 on both sides

12b=4b-24

Now subtract 4b on both sides

8b=-24

Now divide 8 on both sides

b= -3

Answer:

-20

Step-by-step explanation

To make the sentence into an equation it would be y+13=(-17). To solve this you would need to get y by itself. To do this, you would make the equation y+13-13 , since you need to do the same thing from both sides, it would be y+13-13=(-17)-13 . Simplify the equation to make y=(-7)-13 . Counting back 13 from -7 gets you to -20 . Finally you get to  y=(-20) , so the answer is -20

Answer:

The original selling price is $520.632

Explanation:

Consider the initial selling price be $x

After marking down 10%,

Final Selling price  = Selling price(1-10%)

Selling price = x – 10% of x = x – 0.1x = 0.9x

After marking 30%

Final Selling price  = Selling price(1-10%)

Selling price = 0.9x – 0.3*0.9x = 0.9x – 0.27x = 0.63x

According to the question,

0.63x = 328

Therefore, the original selling price is $520.632

Answer:

78.75 ?

Step-by-step explanation:

calculator..

The volume of water remain in the tank after 30 seconds is 78.75 liters.

The given parameters;

The amount of water drained after 30 seconds is calculated as follows;

[tex]V_1 =2.5 \ \frac{liters}{\min} \times \frac{1 \min}{60 \ s} \times 30 \ s\\\\V_1 = 1.25 \ liters[/tex]

The volume of water remain in the tank after 30 seconds is calculated as follows;

V₂ = V₀ - V₁

V₂ = 80 liters - 1.25 liters

V₂ = 78.75 liters

Thus, the volume of water remain in the tank after 30 seconds is 78.75 liters.

Answer:

The cost of an orange tree is $ 6 while that of a grapefruit tree is $

Step-by-step explanation:

Let x be the cost of an orange tree and y be the cost of a grapefruit tree. In the first week, the citrus grower purchased 25 orange trees and 20 grapefruit trees for $290, so 25x + 20y = 290 (1).

In the next week, the grower bought 20 orange trees and 30 grapefruit trees for $330. So, 20x + 30y = 330 (2)

From (2) y = (330 - 20x)/30 = (33 - 2x)/3

substituting y into (1), we have

25x + 20[(33 - 2x)/3] = 290

multiplying through by 3, we have

75x + 20(33 - 2x) = 870

expanding the bracket, we have

75x + 660 - 40x = 870

collecting like terms, we have

75x - 40x = 870 - 660

35x = 210

dividing both sides by 35, we have

x = 210/35

x = 6

substituting x = 6 into y, we have

y = (33 - 2x)/3

= (33 - 2(6))/3

= (33 - 12)/3

= 21/3

= 7

So the cost of an orange tree is $ 6 while that of a grapefruit tree is $ 7.

Yes that is indeed correct
