The sum of 2 numbers is 80.the ratio of these 2 numbers is 3:5.find the larger number

1 answer:

4 0

Hello,

Let's assume a the smaller number,b the larger.

a+b=80
a/b=3/5==>a=3/5*b

3/5b+b=80
==>8/5b=80
==>b=80*5/8
==>b=50
a=80-50=30
The lager number is 50

Step-by-step explanation:

We are given,

A cube with side equal to inches.

As we know,

Volume of a cube =

Thus, we get,

Volume of the given cube is,

Volume =

The first three steps in determining the solution set of the system of equations, y = –x2 – 2x + 8 and y = 2x + 11, algebraicall

shutvik [7]

First step
Using substitution you can fill 2x + 11 in for the y part of the first equation
This will look like: 2x + 11 = -x^2 -2x + 8

Second step
Now we need to solve for the variable by combining like terms you can start by adding x^2 + 2x -8 to both sides
You get 0 = x^2 +4x +3

Third step
Factor
(X+3)(x+1)=0

If you need the y values you can fill in x= -3 to the second equation y= 2(-3) + 11 and y=5
First point is (-3,5)

The other point is found by filling x=-1 into the second equation: y= 2(-1) +11 and y = 9
Second point is (-1,9)
