Answer:
Option c
Step-by-step explanation:
A system of equations are given to us. And we need to solve them . The given system is
We numbered the equations here . Now put the value of equation 1 in equation 2 that is substituting y = 2x - 3 in eq. 2 .
We got two values of x as 0 & 2 . Alternatively substituting these values we have ,
Thefore the required answer is ,
Answer:
121
Step-by-step explanation:
A calculator can answer this for you.
_____
Following the steps of the <em>order of operations</em>, you evaluate inner parentheses first. The exponents are the first to be evaluated there.
11[6^2/(5^2-4^2)+7]
= 11[6^2/(25 -16)+7]
= 11[6^2/9 +7]
Then you do the exponent ...
= 11[36/9 +7]
Now you do the division ...
= 11[4 +7]
And finally, you can finish up the outer parentheses ...
= 11·11
= 121
Using a system of equations, it is found that the lengths of the sides of the triangle are given as follows:
0.91 feet, 0.73 feet, 1.23 feet.
<h3>What is a system of equations?</h3>A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are the lengths, given by x, y and z.
The length of one side of a triangle is 2 feet less than three times the length of its second side, hence:
y = 3x - 2.
The length of the third side is 3/4 of the sum of the lengths of the first two sides, hence:
The perimeter of the triangle is 17.5 feet, hence:
x = 25.5/28
x = 0.91.
Then the other sides are:
