Given:
The expression is
[tex]8p+3q-18[/tex]
To find:
The value of the expression when [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex].
Solution:
We have,
[tex]8p+3q-18[/tex]
Putting [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex], we get
[tex]8(\dfrac{1}{2})+3(7)-18[/tex]
[tex]=4+21-18[/tex]
[tex]=7[/tex]
Therefore, the value of the expression is 7 when [tex]p=\dfrac{1}{2}[/tex] and [tex]q=7[/tex].

Use the table below to determine whether f(x) could represent a linear function. If it could write f(x) in the form f(x) = mx +b.
Answer:
5x-3
Step-by-step explanation:
This is linear because the numbers are changing at a constant rate (of 5)
We can also see that when x=0 y= -3 which means that in our equation
y=mx+b
-3 =b
I said prior that the rate of change is 5 which means that our slope is 5
which means that our equation looks like
5x-3
The reading of a scale at one end is 3.5 cm and at the other end is 18.5 cm. Calculate the lengths of the needle
Answer:
15 cm
Step-by-step explanation:
Given that :
Reading at one end, initial reading = 3.5 cm
Reading at the other end, final reading = 18.5 cm
Length of needle :
Final Reading - Initial reading
18.5cm - 3.5cm
= 15cm

Ivy and her brother, Hayden, each got a box of chocolates for Valentine’s Day. Her box contained 12 chocolates, and his box contained 10 chocolates. They both knew that their dad loved chocolate, so they each gave him half of their chocolates. Also, they each gave their mother two chocolates; then they ate the rest. How many chocolates did Ivy get to eat? How many chocolates did Hayden get to eat?
Answer: 10 and a half For ivy For Hayden 8 half
Step-by-step explanation: because ivy gave Her mother 2 each and her father half and for her brother
Answer:
Given to father by Ivy: 12/2=6
Given to father by Hayden: 10/2=5
Now,
Chocolates given to mother by Ivy: 2
Chocolates given to mother by Hayden: 2
Now total chocolates given by Ivy to mother and father: 6+2 = 8
Now total chocolates given by Hayden to mother and father: 5+2=7
Now total chocolates left with Ivy 12-8=4
Now total chocolates left with Hayden: 10-7= 3
Thus ivy and Hayden has 4&3 chocolates respectively

Answer:
12x I think
Step-by-step explanation:
this is very confusing.
2x² + 2x - 4 = 2x ( x + 1 - 2 )
4x + 2x - 4
8x-4
4x = 2x ( x + 1 - 2)
8x + 2 - 2
8x + 4x
= 12x. I think 12x is the correct factor.

Problem 7
Answers:
dots A = 2dots B = 5-----------------------
Explanation:
In step 1, there are 2 dots. So that number (2) fills in the blank for dots A.
Step 2 has 5 dots, which fills in the blank for dots B.
===========================================================
Problem 8
Answer: A) Quadratic
-----------------------
Explanation:
We have this sequence of dots: {1, 2, 5, 10, ...}
Note the increments of +1, +3, +5, ...
The increments aren't the same, so we don't have a linear sequence. But because the increment amounts go up by 2 each time, this strongly implies a quadratic sequence.
The rule for this sequence is n^2 + 1. Whatever the step number (n) is, we square it and add 1 onto that result. For instance, for step 3, we have n = 3 that leads to n^2 + 1 = 3^2 + 1 = 9 + 1 = 10. Also, note how the lone dot on the left of step 3 is tacked onto the 3 by 3 square of dots.
===========================================================
Problem 9
Answers:
dots A = 3dots B = 9-----------------------
Explanation:
Same idea as problem 7
===========================================================
Problem 10
Answer: B) Exponential
-----------------------
Explanation:
The sequence is {1, 3, 9, 27, ...}
In step 3 we have 3 rows and 9 columns of dots to give 3*9 = 27 dots total here.
The sequence is growing by a factor of 3 each time. In other words, we are tripling the terms or multiplying each term by 3 to get the next term.
Therefore, we have an exponential pattern.
The rule is 3^n
Eg: if we're on step n = 2, then we have 3^n = 3^2 = 9 dots.

Step-by-step explanation:
132
Linear pairs always equal 180 degrees.
Therefore, Angle ABC + Angle CBD =180.
We already know Angle CBD is 48.
Therefore, Angle ABC + 48 =180
Subtraction Property of Equality:
Angle ABC = 180-48= 132 Degrees.

The diagram shows a regular 11-sided polygon.
Work out the size of the angle marked d.
Leave answer to 2 decimal places where appropriate.
Answer:
d = 32.73°
Step-by-step explanation:
Angle 'd' is an exterior angle of the given polygon.
By the property of the exterior angles of a polygon, sum of exterior angles of a polygon is 360°.
And the measure of an exterior angle of a polygon = [tex]\frac{360}{n}[/tex]
Here 'n' = Number of sides of the polygon
From the picture attached,
Number of exterior angles of the regular polygon = 11
Therefore, measure of the exterior angle = [tex]\frac{360}{11}[/tex]
= 32.7272
≈ 32.73°

base(b)= y
hypotenuse (h) = x
Then
sin 60 = p/h
[tex]\frac{\sqrt{3} }{2} = \frac{9\sqrt{3} }{x}[/tex]
x = 18
Now
cos 60 = b/h

Ethan needs an 75% average in his writing class to pass. On his first 4 exams,
he earned scores of 68%,72%, 85%, and 90%. What is the minimum score
Ethan can earn on his fifth and final test to pass?
A. 80%
B. 70%
C. 68%
D. 60%
The minimum average score Ethan can earn on his fifth and final test is option (D) 60% is the correct answer.
What is an average?An average of a list of data is the expression of the central value(mean) of a set of data. Average is calculated by adding quantities together and dividing the total by the number of quantities.
For the given situation,
The scores for 4 exams are 68%,72%, 85%, and 90%.
Let the score for the fifth test be x.
Formula for the average,
[tex]A = \frac{Sum of individual scores}{Total number of tests}[/tex]
⇒ [tex]75=\frac{68+72+85+90+x}{5}[/tex]
⇒ [tex]375=315+x[/tex]
⇒ [tex]x=60[/tex]
Hence we can conclude that the minimum average score Ethan can earn on his fifth and final test is option (D) 60% is the correct answer.
