The cost of 1 hamburger is $ 2.5 and cost of 1 fries is $ 0.8
<h3><u>Solution:</u></h3>
Let "f" be the cost of 1 fries
Let "h" be the cost of 1 hamburger
<em><u>Given that, tennis coach took his team out for lunch and bought 8 hamburgers and 5 fries for $24</u></em>
8 x cost of 1 hamburger + 5 x cost of 1 fries = 24
8h + 5f = 24 -------- eqn 1
<em><u>The players were still hungry so the coach bought six more hamburgers and two more fries for $16.60</u></em>
6 x cost of 1 hamburger + 2 x cost of 1 fries = 16.60
6h + 2f = 16.60 ------ eqn 2
<em><u>Let us solve eqn 1 and eqn 2</u></em>
Multiply eqn 1 by 2
16h + 10f = 48 ------ eqn 3
Multiply eqn 2 by 5
30h + 10f = 83 -------- eqn 4
<em><u>Subtract eqn 3 from eqn 4</u></em>
30h + 10f = 83
16h + 10f = 48
( - ) ----------------------
14h = 35
<h3>h = 2.5</h3>
Substitute h = 2.5 in eqn 1
8(2.5) + 5f = 24
20 + 5f = 24
5f = 4
<h3>f = 0.8</h3>
Thus cost of 1 hamburger is $ 2.5 and cost of 1 fries is $ 0.8
Answer:
27 is ta value of x because.. first of all add allthose threee sides
3(x+2)+ 35+ 52=180(the sum of triangle)
or, 3x+6+35+52=180
or,3x=180-93
or,x=87/3
Therefore, the value of x is 29

Answer:
Divide by 4, because 4 is a factor of 88.
Step-by-step explanation:
This is incorrect reasoning because what the constant is on the right side of the equation has nothing to do with the number you are dividing by. In other words, you are dividing by 4 because that isolates the x-variable, and if it was 5x you would divide by 5. The number that you are dividing by only is determined by what number isolates x.
Im pretty sure it would be ordered: -2 1/2, -1/2, |1/2|, 1 1/2, |-2|, |-2 1/2|
This is because
-1/2 stays as -1/2
the absolute value of |-2| is 2
the absolute value of |1/2| is 1/2
the absolute value of |-2 1/2| is 2 1/2
-2 1/2 stays as -2 1/2
and 1 1/2 stays the same as well.
If you take all these numbers (-1/2, 2, 1/2, 2 1/2, -2 1/2, and 1 1/2) and order them from least to greatest, you would get:
-2 1/2, -1/2, 1/2, 1 1/2, 2, 2 1/2
which is -2 1/2, -1/2, |1/2|, 1 1/2, |-2|, |-2 1/2|
Im not exactly sure if it is all correct, but i hope this helps! :)
