Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard. Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
Hold on, does the equation look like this? (x^2+6)/x-6? Because if so then you'd substitute nine for x first. Then you'd multiply nine by itself getting eighty-one, after that add six to get eighty-seven. substitute nine for x one more and subtract six. take eighty-seven divided by three to get an answer of twenty-nine. But if the equation is saying the square of nine aside from nine squared then you'd have an entirely different problem. That one would look similar to *square symbol*(9)+6/9-6
, You'd solve this by finding the square of nine which is three then you'd add six and get a numerator of nine. Then you go about the bottom the same as you would have in the first equation, subtract six from nine giving you a denominator of three so you now have nine over three which simplified is three.
The two answers are 29 or 3 depending on the equation.
Answer:
Step-by-step explanation:
<u>Wheat flour</u>
- 4 pounds for $8 ⇒ 1 pound for $8/4 = $2
<u>Rye flour</u>
- 5 pounds for $20 ⇒ 1 pound for $20/5 = $4
<u>Equation for total:</u>
Answer:
40 bars
Step-by-step explanation:
Where x = Number of bars purchased by each team
We solve this question by equating both Equations from Company A to Company B
Company A = Company B
0.75x = 10 + 0.50x
Collect like terms
0.75x - 0.50x = 10
0.25x = 10
x = 10/0.25
x = 40 bars
Hence, each team need to purchase 40 bars from each company
Okay so you know a straight line is equal to 180 degrees, so you set them up in an algebraic equation. (5x+2)+48=180 subtract 48 first to get 5x+2=132 Subtract the 2 this time to get 130. Now you end up with 5x=130. Here you divide 130 by 5 to get X=26. If you just need to find the degree of that angle tho you can stop after the first subtraction because the math tells you (5x+2)=132 degrees.
