Answer:
80 minutes
Step-by-step explanation:
Work done by Mark in 1 minute = 1/120
Work done by Alexis in 1 minute = 1/240
Work done by Mark and Alexis in 1 minute = 1/120 + 1/240
They both can load all the packages in 80 minutes.
What you do is distribute the 4.5 into what is inside the parenthesis. This gives you 7+4.5+18x = -17.5. You pass over the 7+4.5 to the other side, which gives you ...
11.5 + 18x = -17.5
-11.5. -11.5
18x = - 29
Then you divide both sides by 18 to isolate the variable
The 23 divided by 4774 is 207.565 so option (D) will be correct.
<h3>What is the arithmetic operator?</h3>
Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given that,
23 divided 4774 ⇒ 4774÷23
Now if we divide 4774 by 23 then it will go 207 times and after the decimal place, it will go 0.5652174 times.
Hence " The 23 divided by 4774 is 207.565".

Okay. So 3 guests are free. Mika has $42 dollars she can spend with $7 per guest. 42/7 = 6. Add the 3 other guests and you get 9. Mika can bring 3 guests with her to the gym. D gives the correct answer, and A and B give out the correct equations as well. C is not right, because 7 * 9 is 63. 63 - 3 is 60. 60 > 42. C is the incorrect equation. The answer is C.
