Answer:
The equation that will determine the cost of two folders is; 3x = 2× $2.91
and the cost of the 2 folders is $1.94
Step-by-step explanation:
To solve this problem, we will follow the steps below;
Using proportion;
Let x be the cost of 2 folders
3 folders = $2.91
2 folders = x
Cross-multiply
3x = 2× $2.91
The equation that will determine the cost of two folders is
3x = 2× $2.91
We can go ahead and solve
3x = $5.82
Divide both-side of the equation by 3
= 
x = $ 1.94
The cost of 2 folders is $1.94
Answer:
7
Step-by-step explanation:
the answer would be 7 because if there is 2 in per hour just go 2,4,6,8,10,12
and then count all the numbers i did and that will be your answer (7)
Answer:
71°
Step-by-step explanation:
All angles inside of a triangle add up to 180°, so you need to find angles that add up properly. First, you should subtract 38 from 180, which gives you 142°. Now, if you look at the outer measurements, you can clearly see that this triangle is isosceles, meaning it has both two congruent sides and angles. So we are left with 142, and it needs to be dispersed evenly into the two angles because they are congruent, so divide by 2 and you get 71° for X.
Exact form is 469/12 decimal form is 39.083 repeating and mixed number form is 39/1/12
Answer: no solution
Step-by-step explanation:
24x + 72 = 24x +12
-24x -24x
———————————
72=12
72 doesn’t equal 12 so the answer is no solution
