Answer:
Step-by-step explanation:
All the three sides are equal. So, it is equilateral triangle.
All the angles are less than 90°, so, it is acute triangle
The expression for the above statement = (7x + 5)/(- 2x + 11)
The correct option is C.

What is algebra?</h3>
One of the many branches of mathematics is algebra. Algebra, which is a common thread throughout nearly all of mathematics, is broadly defined as the study of mathematical symbols and the rules for manipulating these symbols in formulas.
<h3>According to the given information:</h3>
let a number be x
Consequently, the result of seven times a number plus five is
7x + 5
Moreover, add the negative sums of two times the number and eleven.
- 2x + 11
Now, you can write the sentence "the total of seven times a number and five, divided by the sum of negative two times the number and eleven" as
(7x + 5)/(- 2x + 11)
The expression for the above statement = (7x + 5)/(- 2x + 11)

Answ, i just need 5 pts thanks!
Step-by-step explanation:
There are 16 ounces in a pound so 96 divide by 16 is hat?
Think of x being the cost of a knife and y being the cost of a spoon.
x = 3y would show that a knife cost 3 times what a spoon does.
We know from the info that 12 knives and 9 spoons = 82.80. It could be written as 12x + 9y = 82.80
Substitute 3y from our formula into the equation for x.
12(3y) + 9y = 82.80 becomes 36y + 9y + 82.80 which becomes 45y = 82.80, then divide both sides by 45 to solve for y and you get 1.84
Going back to our original equation, x = 3y, we can substitute 1.84 for y and find that x = 5.52.
So we find a knife cost $5.52
