In equations like this, you could use PEMDAS- Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction in that order. Since there are no parentheses or exponents you can go to multiplication. Since x=9 and y=6, you multiply x(9) and y(6) to get 54. Now you can add since there is no division or subtraction involved. 54+ u(2) = 56. So u + xy = B. 56
Answer:
A. Divide by 100
C. Move the decimal point two places to the left
Step-by-step explanation:
To write a percent as a decimal, divide by 100 or move the decimal point two places to the left.
Let 1st integer be x and next consecutive be x+1
1/2•x + 1/5•(x+1) = 10
x/2 + x/5 + 1/5 = 10
-1/5 -1/5
x/2 + x/5 = 49/5
(x/2)•5/5 + (x/5)•2/2 = 49/5
5x/10 + 2x/10 = 49/5
7x/10 = 49/5
•10 •10
7x = 98
÷7 ÷7
x = 14 --> 1st integer
x+1 = 14+1 = 15 --> next consecutive integer
Answer:
8.9 / 9
Step-by-step explanation:
Mathaway!
Take the logarithm of both sides of the equation to remove the variable from the exponent.
Decimal Form: x=8.99999936
Answer:
13.9 inches, 14.1 inches
Step-by-step explanation:
The empirical rule tells you 68% of the distribution lies within 1 standard deviation of the mean:
14.0 ± 0.1 = [13.9, 14.1]
About 68% of outside diameters lie between 13.9 inches and 14.1 inches.
