First, think of your places. You have the ones places, tens places, hundreds places, and so on.
The first number starting from the right is the ones, and as you keep going left, the value of each given digit becomes higher.
Since 5 is in the ones place, its value would be just 5. If it were in the tens place, it would be 50. If it were in the hundreds place, it would be 500, and so on.
Think of it this way;
Ones is just one. If a number is in the 'ones' place, its value would be a single digit. If it were in the tens place, its value would be two digits.
That's how it would be for each place going left.
Every number you move to the left, its value gains a one.
So here's an example:
5555
The value of 5 in the ones place "5555" is simply 5.
In the tens place, you end up adding one zero, so the value of the second five to the left would be, "50"
So with that said, the value of the digit 5 in the number 75 is <em>5.

Answer:
The answer to your question is z = -3
Step-by-step explanation:
Expand 42 = -7(z - 3)
42 = -7z + 21
Simplify 7z = -42 + 21
7z = -21
Clear z z =
z = -3
Answer: 2

Answer:
1.8 x
Step-by-step explanation:
The expression is [3x10^6][6x10^8}
]
Step 1: Multiply the coefficients 3 and 6, we get 18.
Step 2: If we have the same base, we add the powers.
So 10^6 *10^8 = 10^(6 + 8) =
Step 3: Now combine 18 and
= 18 x
The coefficient must be less than 10, in 18, we have one 10, we can move that to the exponent and 18 = 1.8 *10
Step 4: When we simplify, we get 1.8 x
Hope you will understand the steps.
Thank you.
Answer:
72 Wrong, so find how many are right with 135 total
Step-by-step explanation:
It's similar to saying if she answered half and this continued how many would she have answered after answering a bigger number, you would say half.
so she answered 8/15 incorrectly a a smaller number, so she will answer that ratio with a bigger number. If it helps 8/15 is about 53%. just like 1/2 is half. So to find half you would multiply something by 1/2 and int he same way you multiply something by 8/15 to get that proportion of it.
so 135, if you take this 53%, or simply multiply it by 8/15 you get your answer of 72. So 72 wrong so al others are right, which you get with 135-72 = 63.
You could also do 135*(1-8/15) = 135 * 7/15. if you ever want to find something NOT part of the proportion you do 1 - that proportion.
