An equation is formed of two equal expressions. The solution of the system of equations is (0.75, 1.25).

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution to the system of equation is,

y = 2 - x

y = 3x - 1

Substitute the value of y,

y = y

2 - x = 3x - 1

2 + 1 = 3x + x

3 = 4x

x = 3/4 = 0.75

Substitute the value of x in any one of the equation,

y = 2 - x

y = 2 - 0.75

y = 1.25

Hence, the solution of the system of equations is (0.75, 1.25).

Find the surface area.
denpristay [2]

Step-by-step explanation:

a rectangular prism (like this brick) has the same basic structure as a cube (like a die) : it has 6 sides.

while a die has 6 equal sides, a rectangular prism has 3 pairs of equal sides :

top and bottom

left and right

front and back

all we have to do is calculate the areas of the 6 rectangles and add them up. that's it.

your remember, the area of a rectangle is

length × width

in our case we have

top and bottom : 2.5×11.5 × 2 = 28.75×2 = 57.5 in²

left and right : 2.5×5 × 2 = 12.5×2 = 25 in²

front and back : 11.5×5 × 2 = 57.5×2 = 115 in²

so, the total surface area of the whole block is

57.5 + 25 + 115 = 197.5 in²

What is the length of 15,409,000 cubic yard in miles? (to<br> the nearest hundred)
cluponka [151]

Answer:

Step-by-step explanation:

The cube root of 15,409,000 = 248.84 yards.

There are 1760 yards in a mile

One edge of a cube = 248.84 / 1760 = .141386 miles.

So a cube would be .00283cubic miles. Your answer does not reach a hundredth place, I don't think.

What are the solutions for x when y is equal to 0 in the following quadratic
Scrat [10]

Answer: Option C

Step-by-step explanation:

Given the quadratic equation y = x^2 - 13x, substitute y=0:

 0 = x^2 - 13x

In this case, to find the solutions of the given quadratic equation, you must factor out the variable "x". Then:

0=x(x-13)

Therefore, you get that the solutions of this equation are the following:

x=0\\\\\\x-13=0\\x=13

Then, the answer is:

x = 0\ or\ x = 13

This matches with the option C.
