1. The difference of two numbers is 3, and the sum of three times the larger one and
vlada-n [284]

Answer: 25 and 22

Step-by-step explanation:

Since one number is 3 bigger than the other, we can call them x, and x-3.

Then we know that the sum of 3 times x and 2 times (x-3) is equal to 19, so we can make the equation

3x+2(x-3)=19

Simplifying would get you

3x+2x-6=19

adding the x's and adding six to both sides of the equations gets you

5x = 25

divide by 5 and

x=5

Put those numbers back into your previous labels for them, x and x-3, and you get 5 and 2

Hope this helps

7^3 times 7^-7 times 7
dusya [7]

Hello there! :)

<u><em>Answer:\frac{1}{343}</em></u>

<u><em>*The answer must have a fraction.*</em></u>

Step-by-step explanation:

Lesson: Zero and Negative Exponents.

Distributive property: a(b+c)=ab+ac

First, you apply exponent rule.

a^b*a^c=a^b^+^c

7^-^3

\frac{1}{7^3}=7^3=7*7*7=343

Final answer: \frac{1}{343}

Hope this helps!

Thanks!

Have a great day!

Answer:

  • y = 6x + 4
  • Rs. 94

Step-by-step explanation:

<u>Equation for this case is:</u>

⇒ y = 6(x - 1) + 10     as Rs. 10 for the first km and Rs. 6 for the rest (x - 1) km

⇒ y = 6x - 6 + 10      simplifying

⇒ y = 6x + 4             final equation

<u>For x = 15 km we have total of:</u>

  • y = 6*15 + 4 = 94
