The sum of 2 numbers is 70.4. One number is 19 times the other and the smaller number is less than 5. What are the two numbers?

Step-by-step explanation:

Given information

One number is 19 times the other

The smaller number is less than 5

Sum = 70.4

Set variables

Let x be the smaller number

Let 19x be the larger number

Set equation according to the given information

Smaller number + Larger number = Sum

x + 19x = 70.4

Simplify by addition

20x = 70.4

Divide 20 on both sides

20x / 20 = 70.4 / 20

Substitute values into the variables to find the larger number

Larger number = 19x

                         = 19 (3.52)

Hope this helps!! :)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

a)(x-2)^2+(y-1)^2=9
