Answer:

The average weight of okapi  is 290 kg

The average weight of llama is 160 kg

Step-by-step explanation:

To solve the question, we are to resolve the word problem as follows;

Let the average weight of Okapi be X

The average weight of llamas be Y

X + Y = 450 and

3 Y = X + 190

Solving the above simultaneous equation, we have

X = 450 - Y

∴ 3·Y = 450-Y+190

4·Y =640

Y = 160 and X = 450 - 160 = 290

Therefore, the average weight of okapi  = 290 kg while the average weight of llama = 160 kg.

eduard

Answer:

  • \boxed{\sf{14}}

Step-by-step explanation:

\boxed{\underline{\text{ORDER OF OPERATIONS:}}}

Use the order of operations.

Note: PEMDAS or BODMAS stands for:

<u>PEMDAS</u>

  • <u>Parentheses</u>
  • <u>Exponents</u>
  • <u>Multiply</u>
  • <u>Divide</u>
  • <u>Add</u>
  • <u>Subtract</u>

<u>BODMAS</u>

  • <u>Brackets</u>
  • <u>Order</u>
  • <u>Divide</u>
  • <u>Add</u>
  • <u>Subtract</u>

<u>First, do parentheses.</u>

3+6*(5+4)÷3-7

(5+4)=9

\Longrightarrow: \sf{3+6* 9\div 3-7}

<u>Do multiply and divide.</u>

6*9=54

54/3=18

<u>Then, rewrite the problem down.</u>

\Longrightarrow: \sf{3+18-7}

<u>Add.</u>

\sf{3+18=21}

\sf{21-7=\boxed{\sf{14}}

\Longrightarrow: \boxed{\sf{14}}

  • <u>Therefore, the correct answer is "C. 14".</u>

I hope this helps, let me know if you have any questions.
