Answer:
use your head
Step-by-step explanation:
1) 8y + 9 2) 2n + 4 3) 3d + 5h
rearrange the equations and combine like terms. combine the terms with the same variables and add / subtract them.
for example number 1:
9y - 11 + 20 - y
is the same thing as
<em>9y - y</em> <u>+ 20 - 11</u>
and now you can easily combine them:
<em>8y</em> + <u>9</u>
i hope this helps!
Question options:
A. Yes, Walter is correct.
B. No 3.612 is less than 13.
C. No, both 3.612 and 3.622 are greater than
D. No, both 3.612 and 3.622 are less than 13
Answer:
C. No, both 3.612 and 3.622 are greater than the square root of 13
Explanation:
13 is a prime number and must have a decimal number as its square root and so the square root should be between √9 and √16
Using the Newton Raphson method to estimate the square root of 13 with the formula: ai +1= ai²+n/2ai
We get square root of 13 = 3.6055512
This is the same result we get using a calculator to calculate square root of 13= 3.6055512
So yes Walter is not correct
Answer:
x = 7
y = 12
Step-by-step explanation:
The key to solving this problem is understanding the properties of exponents:
If you are multiplying two powers with the same base (in this case the base is 6), the result is the base raised to the power of the two exponents added together.
6^1/3+1/4 = 6^x/y
6^7/12 = 6^x/y
So the product would be 6^7/12
Therefore, the answers are:
x = 7
y = 12
Answer:
Trigonometry can be used to measure the height of a building or mountains: if you know the distance from where you observe the building and the angle of elevation you can easily find the height of the building.
