What is the sum of two numbers is 45 and theire difference is 5
adelina 88 [10]

Answer:

let the two numbers be x and y

x+y=45(equation 1)

x-y=5(equation 2)

from equation (1) y=45-x(equation 3)

substitute 45-x for y in equation 2

x-(45-x)=5

x-45+x=5

x+x-45=5

2x-45=5

2x=45+5

2x=50

x=50/2

x=25

Can someone help me with this please?
irakobra [83]

Answer:

b. 28.1

Step-by-step explanation:

By the property of intersecting secant and tangent out side of the circle.

20 \times (20 + x) =  {31}^{2}  \\ 20(20 + x) = 961 \\ 20 + x =  \frac{961}{20}  \\ 20 + x = 48.05 \\ x = 48.05 - 20 \\ x = 28.05 \\ \huge \red{ \boxed{ x = 28.1}}
