Answer:
87.125 is rational
Step-by-step explanation:
it is a rational number because it can be represented as a fraction
To solve for x, you need to isolate/get x by itself in the equation:
Square ² both sides to get rid of the square root √
![(\sqrt{x-2} )^2=(0)^2](https://tex.z-dn.net/?f=%28%5Csqrt%7Bx-2%7D%20%29%5E2%3D%280%29%5E2)
x - 2 = 0 Add 2 on both sides
x - 2 + 2 = 0 + 2
x = 2
Answer:
amount of nuts = 2 pounds
amount of dried fruit = 4 pounds
Explanation:
We are given that x is the amount of nuts and y is the amount of dried fruit.
We are also given that:
1- Hunter needs to make 6 pounds of trail mix. This means that:
x + y = 6
This can be rewritten as:
x = 6 - y .........> equation I
2- x costs $4 per pound, y costs $3.5 and Hunter can spend a total of $22. This means that:
4x + 3.5y = 22 ..........> equation II
Substitute with equation I in equation II and solve for y as follows:
4x + 3.5y = 22
4(6-y) + 3.5y = 22
24 - 4y + 3.5y = 22
24-22 = 4y-3.5y
2 = 0.5y
y = 4 pounds
Substitute with y in equation I to get the value of x as follows:
x = 6-y
x = 6-4
x = 2 pounds
