If these both men were working at normal hours, and then, (John) worked "2 more hours" than Gary has, this would just mean that he has worked more.
x+2= x+2.
Now if John has worked the double amount, 4 more times than Gary's usual hours, this would mean something quite different.
Then the expression would look like, (x+2×4x)
We don't know how many hours are the "usual hours", this is what "x" would then represent.
John has then worked (4×2+x) more hours than Gary.
Your answer: (4×2+x)

Answer:
A. 20
Step-by-step explanation:
We know that there are 8 eights in a whole, and a whole is equal to the number 1. The number 2 consists of two wholes, and so we multiply 8 by 2.
8 wholes in each 1 × 2 ones = 16 wholes
Now, we know that the number 2 is equal to 16 wholes, so now we need to find how much 1/2 of a whole is worth.
1 whole = 8 eights, so divided by 2, it would be 4 eights for a half of a whole.
So, we add 16 + 4 to get the result of 20.
Hi!
In math, anything that is just grouped together with a bunch of different numbers, operators, or symbols is an expression.
By numbers, I mean your usual 1, 2, 3, 4, 5, 6, 7, 8, 9, etc.
By operators, I mean the operators we use to do calculations with. This will be multiplication, division, addition, and subtraction.
By symbols, I just mean any ol' symbol we can shove in there. This can be pi or stuff such as the actual symbols for our operators. (*, /, +, -). Some more examples would be parentheses and inequality symbols.
So, let's make our own expression.
5 + 9x - (-2x)^2 is in fact an expression! We have numbers, operators, and some symbols.
Also, note that variables are really common in expressions. Don't let them mess you up.
With this new found knowledge, you can answer this question on your own!
Hopefully, this helps! =)
Answer:
104.8cm³(1 decimal place)
Step-by-step explanation:
Volume of a cone is given by the formula
V=1/3πr²h
we are given a radius of 5 and a height of 4 so we will just substitute for the values and we will give our pie as 22/7
V=1/3× 22/7×5²×4
V=1/3 × 22/7 ×25 ×4
V=2200/21
V=104.76190476
V=104.8cm³(1decimal place)
