6x = 2x + 36
show your work pls this a test pls
Answer:
x=9, so the answer is 9
Step-by-step explanation:
First collect like-terms, divide both sides, and get nine
6x=2x+36 > 6x-2x=36 > 4z=36 then divide and get nine :)
Answer:
x = 9
Step-by-step explanation:
Not supposed to be answering this because it is a test but oh well.
Start by isolating the x. Move the 2x to the left by subtracting it from both sides.
4x = 36
Now divide both sides by 4 to isolate the x
x = 9

Which compound inequality is represented by the graph?
(A.) -2
(B.) -2_
(C.) x<-2 or x_>4
(D.) x_<-2 or x>4
Answer: Choice C
[tex]x < -2 \ \text{ or } \ x \ge 4[/tex]
========================================================
Explanation:
The blue portion on the left is represented by [tex]x < -2[/tex] as it describes values smaller than -2. Notice the open hole at -2 which indicates we do not include this value. So that's why we go with [tex]x < -2[/tex] instead of [tex]x \le -2[/tex]
The blue portion on the right is represented as [tex]x \ge 4[/tex] describing values that are equal to 4, or larger than 4.
So overall, the entire graph visually represents x values such that [tex]x < -2 \ \text{ or } \ x \ge 4[/tex]
Side note: the "or" means we pick one region or the other, but not both regions at the same time.

A scale drawing of an office space uses a scale of 1 in : 5 yd. The scale drawing has an area of 12 square inches. What is the area of the actual office space
Answer:
60 Yards.
Step-by-step explanation:
Ooooooooo Proportion question!
We can write an equivalent fraction here:
[tex]\frac{1}{5} =\frac{12}{x}[/tex]
Because 12 wold be equivalent to the 1 inches.
We can multiply by 12 because 1*12 would be 12.
5*12=60.
x=60, which is the answer.
Your friend claims that the only solution to the trigonometric equation tan B = square root of 3 is B = 60 degrees. Is your friend correct? Explain your reasoning
Answer:
Yes, Friend is correct.
Step-by-step explanation:
Given:
Tan B = √3
Find:
Value of B
Computation:
Tan B = √3
Tan B = Tan 60°
By comparing
B = 60°
Yes, Friend is correct.
A quadratic function, f(x) = x2 + bx + 9, is such that there is only one real root. Which of the following are possible values of b?
I. b = 2
II. b = 6
III. b = -6
IV. b = -2
A. I, II, III, and IV
B. I and IV only
C. II and III only
D. I only
Answer:
C
Step-by-step explanation:
Remember that we can use the discriminant to determine the amount of roots that a quadratic function has.
If the determinant equals 0, then we only have one real root.
Our function is given by:
[tex]f(x)=x^2+bx+9[/tex]
Then the discriminant will be:
[tex]\Delta = b^2-4(1)(9)=b^2-36[/tex]
We only have one real root, thus our discriminant must be 0:
[tex]0=b^2-36[/tex]
Solve for b:
[tex]b^2=36[/tex]
Thus:
[tex]b=\pm 6[/tex]
The answer is both II and III.
The final answer, then, is C.
Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at? Include the steps you used to solve the problem and your answer
Answer:
3%
Step-by-step explanation:
Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at?
This is a simple interest question
The formula to find the rate is given as:
Equation:
r = (1/t)(A/P - 1)
t = time = 4 years
P = Principal = $12500
I = Simple Interest = $1500
A = Total Amount = Principal + Simple Interest = $12500 + $1500
= $14000
Calculation:
Solving our equation:
r = (1/4)((14000/12500) - 1) = 0.03
r = 0.03
Converting r decimal to R a percentage
R = 0.03 * 100 = 3%/year

You and your cousin go out to eat and you both have the same taste today and order the same item. You both order the $9 item and both have a $2.50 side item. You receive 50% off your entire bill! You then pay 10% tax on your new discounted bill. What does the bill end up costing you without tip?
The bill is $12.65 without a tip.
Answer:
$12.65
Step-by-step explanation:
The total of just you and your cousin's meals would be $23. Then taking 50% off would be $11.50. Lastly, with the 10% tax, that would make it $12.65. Sorry if I get it wrong.
Loris has one of each of the following colours of felt-tip pen in her pencil case:
red (R) blue (B) yellow (Y) green (G) purple (P)
She pulls out two random pens.
How many different combinations of pairs of colours are there?
there are 10 different combinations of pairs of colors.
What is the combination?Combinations are ways to choose elements from a collection in mathematics where the order of the selection is irrelevant. Let's say we have a trio of numbers: P, Q, and R. Then, combination determines how many ways we can choose two numbers from each group.
Given, Loris has one of each of the following colors of felt-tip pen in her pencil case: red (R) blue (B) yellow (Y) green (G) purple (P) She pulls out two random pens.
from the formula of combination;
total combination ⁿCₓ = [tex]\frac{n!}{(n-r)! * r!}[/tex]
Where, n = total numbers
r = desired number out of total
In our case
n = 5 and r = 2
Thus, the Total combination = ⁵C₂
Total combination = 5! / (3! *2!)
total combination = 5 *4 /2 = 10
therefore, There are ten distinct ways to pair the colors together.

6) Walmart and Target are having deals on Barbie dolls. Walmart is selling 8 dolls for $120 and Target is selling 6 dolls for $102. Which store has the better deals on Barbie dolls? Explain how you know
Answer:
Walmart has the better deal
Step-by-step explanation:
If you do $120/8 dolls you get $15 for each doll at Walmart. If you do $102/6 dolls you get $17 for each doll. You know $15 is less than $17 making it cheaper and a better deal. Target's dolls are $2 more than Walmart. $17-$15=$2

Answer:
width = 40 cm
Step-by-step explanation:
Since the pentagons are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{4x}{x}[/tex] = [tex]\frac{48}{x+2}[/tex] ( cross- multiply )
4x(x + 2) = 48x ← distribute left side
4x² + 8x = 48x ( subtract 48x from both sides )
4x² - 40x = 0 ← factor out 4x from each term on left side
4x(x - 10) = 0
Equate each factor to zero and solve for x
4x = 0 ⇒ x = 0
x - 10 = 0 ⇒ x = 10
However, x > 0 then x = 10
Thus width = 4x = 4 × 10 = 40 cm

How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Answer:
1200 ounces
Step-by-step explanation:
How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Let us represent
Number of ounce of 10% copper = x
Hence, our Equation =
x × 10% + 600 × 70% = (x + 600) × 30%
0.1x + 420 = (x + 600)0.3
0.1x + 420 = 0.3x + 180
Collect like terms
0.3x - 0.1x = 420 - 180
0.2x = 240
x = 240/0.2
x = 1200 ounces

4(v+7) = -6(3v-4) +8v
Answer:
v=−27
Step-by-step explanation:
Since v is on the right side of the equation, switch the sides so it is on the left side of the equation.
−6(3v−4)+8v=4(v+7)
Simplify −6(3v−4)+8v
−10v+24=4(v+7)
Simplify 4(v+7).
−10v+24=4v+28
Move all terms containing v to the left side of the equation.
−14v+24=28
Move all terms not containing v to the right side of the equation.
−14v=4
Divide each term by −14 and simplify.
v=−27
The result can be shown in multiple forms.
Exact Form:
v=−27
