A mistake was made in the steps shown to simplify the expression. Which step includes the mistake?
9/2+ 3(4 – 1) – 7 + 23
Step 1: = 9/2+ 3(3) — 7 + 23
Step 2: = 9/2 + 3(3) - 7 + 8
Step 3: =15/2 (3) — 7+8
Step 4: =45/2 - 7+8
Step 5: =31/2 +8
Step 6: =47/2
Answer: step 3 maybe?
Step-by-step explanation:
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.

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

For this exponential function what is the output value (y) when the input value (c) is 3?
Answer:
y = 40
Step-by-step explanation:
Given, y = 5 * 2^x
If x = 3, y would be:
Substitute the value of x into the given function.
Thus,
y = 5*2³
y = 5*8
y = 40

Answer:
3. All you did was switch the numbers, so it will still equal the same :)
4. 8a and the other 8a cancel each other out, so since 8 has no variables, it ends up by itself.
3. Find the value of 18 – 3 x 5 - 2. Guys please I need help!!
Answer:
1
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.

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
Is it similar to BAK??
Answer:
No
Step-by-step explanation:
If we add up numbers in one line segment like 15+25 and 10+6 we do not get multiples so the triangle GYK is not similar to BAK

Answer:
B. n + 9
Step-by-step explanation:
Given:
n² + 3n - 54
Let's factorize
n² + 9n - 6n - 54
n(n + 9) -6(n + 9)
(n - 6)(n + 9)
Therefore, out if the options given, n + 9 is the expression of the factor of n² + 3n - 54.
Sarah has just received a box of chocolates from a dear friend. Her friend tells her that inside the box there are two kinds of chocolate: milk and dark. There are more milk chocolates than dark chocolates. Subtracting the number of dark chocolates from the number of milk chocolates gives 5 as an answer. The number of milk chocolates is twice that of dark chocolates. How many dark chocolates are there?

Turn this improper fraction in mixed numbers.23/7
Answer:
3 2 /7
Step-by-step explanation:
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

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.
