Find the exact value of x

Step-by-step explanation:

idk what grade you're in but I solved it using a system of equations. there could be an easier method but this is what I did:

1. label each of the sides x, y, z

2. SINCE they're all right angle triangles we can use Pythagorean theorem to create the base generation equation

3. rewrite whole formula in terms of x with y in its components

4. using the mini triangle x can also be rewritten with z in its components

5. equate them together to isolate for a variable, z

6. solve for y by rewriting a formula using the other mini triangle

7. now plug on the equation u isolated with z to get y value

8. plug y back into the formula you wrote in terms of x

to check:

6^2 + 6.71^2

= 81 which equals the hypotenuse of the while triangle

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
