Step-by-step explanation:
Remember PEMDAS:
P: we have no parenthesis, so skip this step.
E: no exponents either.
MD (multiplication and division): we have 3x5. when we calculate this, it is equal to 15. Therefore our equation is now simplified to 18-15-2.
AS (addition and subtraction): Subtract in order of first to last. The answer is 1.

What is the value of x in the equation -2/9x2/5 ?
A. -1 4/5
B. -5/9
C. 5/9
D. 1 4/5
Answer:
-1 4/5
Step-by-step explanation:
-2/9x = 2/5
(multiply both equations by 9 and 5)
So
-10x = 18
(divide both equations by -10)
x = - 18/10
Simplify:
x= - 9/5
= - 1 4/5

Step-by-step explanation:
a train travels 16 miles in 20 minutes how many minutes would 12 miles be
Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
16 miles = 12 miles
20 mins. how many mins?
16 = 12 cross multiply 16? = 240 divide by 16 240 divided by 16 = 15 miles
20 ? because 15 x 16 = 240
Answer:
It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
Write and solve an equation of ratios:
16 miles 20 min
----------- = -----------
12 miles x
Then 16x = 240, and x = 240/16 = 15.

Choose 3 values that would make this inequality true. 7n ≤ 21
Answer:
A couple could be 2, 1, or even a decimal 1.3 as an example.
Step-by-step explanation:
Divide both sides by 7:
7n/7 < 21/7
n < 3
Any value of n less than 3 will make the inequality true, so just pick three values (numbers) for n that are less than 3, such as n = 2.

Identify in the given expressions, terms which are not constants. Give their numerical coefficients.
(i) 5x – 3
(ii) 11 – 2y2
(iii) 2x – 1
Given:
The expression are
(i) [tex]5x-3[/tex]
(ii) [tex]11-2y^2[/tex]
(iii) [tex]2x-1[/tex]
To find:
The terms which are not constants and their numerical coefficients.
Solution:
Constants: The terms which are free from variables.
Numerical coefficient: Number multiplied with a variable.
(i) [tex]5x-3[/tex]
Constant = -3
Term which is not constant = 5x
Numerical coefficient = 5
(ii) [tex]11-2y^2[/tex]
Constant = 11
Term which is not constant = [tex]-2y^2[/tex]
Numerical coefficient = -2
(iii) [tex]2x-1[/tex]
Constant = -1
Term which is not constant = 2x
Numerical coefficient = 2
Therefore, the terms which are not constants are [tex]5x,-2y^2,2x[/tex] respectively and their numerical coefficients are 5, -2, 2 respectively.
The length of a rectangle is 9” greater than the width. The area is 36”2. Find the dimensions
Answer:
Step-by-step explanation:
L = W+9
area = LW = 36
(W+9)W = 36
W²+9W-36 = 0
W = -12, 3
-12 is an extraneous solution, so W = 3 inches
L = W+9 = 12 inches
