Answer: G = 2E + 3
<u>Step-by-step explanation:</u>
Let E represent Elena's age.
Then Gary(G) is two times Elena(E) plus 3 --> G = 2E + 3
The answer is: [D]: "Subtract 5 from 10" .

Explanation:
____________________________________
Use the correct order of operations, according to the mnemonic:
"PE MD AS".
The "P" stands for "parentheses", which takes top (first priority); and there are values in parentheses in this expression—specifically, the "(10 - 5)" . So the first step is to "subtract 5 from 10" —which is: "Answer choice: [D]".
Your error was starting at the beginning of the problem; and not using the "order of operations".

The rest of the question is the attached figure.
============================================
Δ AYW a right triangle at Y ⇒⇒⇒ ∴ WA² = AY² + YW²
And AY = YB ⇒⇒⇒ ∴ WA² = YB² + YW² → (1)
Δ BYW a right triangle at Y ⇒⇒⇒ ∴ WB² = BY² + YW² → (2)
From (1) , (2) ⇒⇒⇒ ∴ WA = WB →→ (3)
Δ CXW a right triangle at Y ⇒⇒⇒ ∴ WC² = CX² + XW²
And CX = XB ⇒⇒⇒ ∴ WC² = XB² + XW² → (4)
Δ BXW a right triangle at Y ⇒⇒⇒ ∴ WB² = XB² + XW² → (5)
From (4) , (5) ⇒⇒⇒ ∴ WC = WB →→ (6)
From (3) , (6)
WA = WB = WC
given ⇒⇒⇒ WA = 5x – 8 and WC = 3x + 2
∴ <span> 5x – 8 = 3x + 2</span>
Solve for x ⇒⇒⇒ ∴ x = 5
∴ WB = WA = WC = 3*5 + 2 = 17
The correct answer is option D. WB = 17
So
2/6 of 318=106
so 106-1/2 or 106/2=53
So he has 53 boxes left
Answer:
11, 13
Step-by-step explanation:
an odd number can be represented by 2n+1
since they are consecutive, the larger odd number will be 2n + 1 + 2
now,
2(2n+3) = 2n + 1 +15
solving this eqn, we get n = 5
so the two numbers are (2n+1) = 11 and 11+2= 13
