Answer: D
Step-by-step explanation:
(3 + 2i) (3-2i) = 13
Depends on if you are going off of a graph or an equation. In a graph, it is where a line crosses the y-axis. In an equation, it is the constant.
Ratio is 7:9
add the ratio it becomes 16
272 members divided by 16
that makes it 17 per one ratio
women ratio is 9
17x9 is 153
i=153 women in the sports club
same thing with ii except it’s divided by 7
91/7 is 13
which means 13 per ratio
there are 9 ratios of women
9x13=117
ii=117 women in a sports club with 91 men with a ratio of 7:9
Can you write out the question or is there a diagram?
Answer:
Step-by-step explanation:
The equations would look like this:
x + 8x + x + 100 = 840
Combine like terms.
10x + 100 = 840
Subtract 100 from each side.
10x = 740
Divide both sides by 10.
x = 74
So, that makes one of the numbers 74.
Now, we're gonna substitute 74 into 8(x) to find the second number.
8(74) = 592
So, the next number is 592.
592 + 74 = 666
840 - 666 = 174
So, the numbers are 74, 592, and 174
If you'd like to check the answer, plug the numbers back into the equation:
74 + 8(74) + 74 + 100 =
840.
