Answer:
t = -9
Step-by-step explanation:
t = 4t + 27
-t -t
0 = 3t + 27
-27 -27
-27 = 3t
÷3 ÷3
-9 = 3t or 3t = -9

If y is directly proportional to x, and y = 56 when x = 6, what is
the value of x when y = 84?
A)6
B)9
C)13
D)15
Answer:
B) 9
Step-by-step explanation:
According to the statement, we have the following relationship:
[tex]y \propto x[/tex]
[tex]y = k\cdot x[/tex] (Eq. 1)
Where:
[tex]k[/tex] - Proportionality constant, dimensionless.
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
Such constant is eliminated by constructing this relationship:
[tex]\frac{y_{2}}{y_{1}} = \frac{x_{2}}{x_{1}}[/tex]
[tex]x_{2} = \left(\frac{y_{2}}{y_{1}} \right)\cdot x_{1}[/tex] (Eq. 2)
If we know that [tex]y_{1} = 56[/tex], [tex]x_{1} = 6[/tex] and [tex]y_{2} = 84[/tex], then the value of [tex]x_{2}[/tex] is:
[tex]x_{2} = \left(\frac{84}{56} \right)\cdot (6)[/tex]
[tex]x_{2} = 9[/tex]
Hence, the correct answer is B.
Chris purchased a video game for the sale price of $35, not including tax. It had been discounted 30%. What was the original price of the game?
Answer:
$50
Step-by-step explanation:
To find the original price, divide the new price by the 0.7, since the discount was 30%:
35/0.7
= 50
So, the original price of the game was $50
Answer:
$50
Step-by-step explanation:
.3 multiplied by 50= 15, then add 15 to 35 to get 50

What is the equation of a line with slope -2/7 and intercept (0, -1)?
A) y = -2/7x
B) x = -2/7y - 1
C) y = -1
D) y = -2/7x - 1
Please show work so I can understand.
Answer:
D
Step-by-step explanation:
Recall the slope-intercept form of a line:
y = mx + b
slope -2/7 means m = -2/7
y = -2/7x + b
Intercept at (0, -1)
x = 0 and y = -1.
Hence, let's plug it back into the equation we made earlier (y = -2/7x + b)
(-1) = -2/7(0) + b
-1 = b
b must be -1
y = -2/7x -1

absolute value of -7 -5
Answer: for -7 is 7 for -5 is 5
Step-by-step explanation: the absolute value of a number is its distance from zero on the number line. For example, -7 is 7 units away from zero, so its absolute value would be 7.
Sometimes referred to as a numerical value, the absolute value is the non-negative value of a real number without regard for its sign. For example, the absolute value of both 12 and -12 is 12.
The absolute value of -5: |−5| is the absolute value of a negative number. To find the answer to this, you simply remove the negative sign, so the answer is 5

∠GHK is a straight angle.
Find m∠LHK .
Answer:
∠ LHK = 101°
Step-by-step explanation:
The 2 angles on a straight line are supplementary, thus
∠ LHK = 180° - 79° = 101°
The given parameters are illustrations of angles on a straight line. The measure of [tex]\angle LHK[/tex] is [tex]101^o[/tex]
Given that:
[tex]\angle GHL = 79^o[/tex]
Using the angle on a straight line theorem, we have:
[tex]\angle GHL + \angle LHK =180^o[/tex] ---- angle on a straight line is 180
Substitute [tex]\angle GHL = 79^o[/tex]
[tex]79^o + \angle LHK = 180^o[/tex]
Collect like terms
[tex]\angle LHK = 180^o - 79^o[/tex]
[tex]\angle LHK = 101^o[/tex]
Hence, the measure of [tex]\angle LHK[/tex] is [tex]101^o[/tex]

Every 8th person at a concert receives a free t-shirt. Every 10th person receives a free keychain. If there are 160 people who attended the concert how many people will receive both a t-shirt and a keychain?
Answer:
4 people will receive both a t-shirt and a keychain.
Step-by-step explanation:
To determine how many people will receive both a t-shirt and a keychain,
First we will determine those that will receive a t-shirt and as well determine those that will receive a keychain.
For those that will a receive a t-shirt
Since every 8th person receives a t-shirt, then
The 8th, 16th, 24th, 32nd, 40th, 48th, 56th, 64th, 72nd, 80th, 88th, 96th, 104th, 112th. 120th, 128th, 136th, 144th, 152nd, and 160th persons will receive a t-shirt.
For those that will receive a keychain
Since every 10th person receives a keychain, then
The 10th, 20th, 30th, 40th, 50th, 60th, 70th, 80th, 90th, 100th, 110th, 120th, 130th, 140th, 150th, and 160th persons will receive a keychain.
From above, those that will receive both a t-shirt and a keychain are the 40th, 80th, 120th, and 160th persons.
Hence, 4 people will receive both a t-shirt and a keychain.

A researcher studies the rate of progress of a chemical reaction. The researcher fixes the temperature and pressure, varies the amount of catalyst used over a range of quantities, and observes the resulting reaction rate in each case.
Which statement BEST describes why the investigation is an experimental study?
There is more than one independent variable to study.
The researcher manipulates at least one independent variable.
It is possible to get data with a range of values of an independent variable.
There is a cause-effect relation between the independent and dependent variables.
Answer:
I think the answer is The researcher manipulates at least one independent variable. Hope this helps.
Step-by-step explanation:
The BEST statement describes is that "The researcher manipulates at least one independent variable."
What are independent and dependent variables?Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on other.
The variables who take their values based on some other variables' values are called dependent variables.
Given that researcher studies the rate of progress of a chemical reaction.
The researcher fixes the temperature and pressure, varies the amount of catalyst used over a range of quantities, since we know that If a variable is taking its values independently of any visible direct cause, then that variable is called independent variable.
Therefore, the BEST statement describes why the investigation is an experimental study;

A rectangle has a perimeter of 14 cm.
Choose all the possible dimensions of the rectangle.
A. 1 cm by 6 cm
B.2 cm pay 5 cm
C. 3 cm by 4 cm
D. 4 cm by 3 cm
E. 5 cm by 2 cm
F. 6 cm by 1 cm
G. 7 cm by 7 cm
H. 8 cm by 6 cm
Answer:
Everything except G and H
Step-by-step explanation:
The perimeter of a shape is the sum of its side lengths.
The possible dimensions of the rectangle whose perimeter is 14 cm are:
A. 1 cm by 6 cm
B.2 cm by 5 cm
C. 3 cm by 4 cm
D. 4 cm by 3 cm
E. 5 cm by 2 cm
F. 6 cm by 1 cm
The perimeter is given as:
[tex]\mathbf{ Perimeter = 14cm}[/tex]
The perimeter of a rectangle is:
[tex]\mathbf{Perimeter = 2 \times (Length + Width)}[/tex]
So, we have:
[tex]\mathbf{A.\ Perimeter = 2 \times (1cm+ 6cm) = 14cm}[/tex]
[tex]\mathbf{B.\ Perimeter = 2 \times (2cm+ 5cm) = 14cm}[/tex]
[tex]\mathbf{C.\ Perimeter = 2 \times (3cm+4cm) = 14cm}[/tex]
[tex]\mathbf{D.\ Perimeter = 2 \times (4cm+3cm) = 14cm}[/tex]
[tex]\mathbf{E.\ Perimeter = 2 \times (5cm+2cm) = 14cm}[/tex]
[tex]\mathbf{F.\ Perimeter = 2 \times (6cm+1cm) = 14cm}[/tex]
[tex]\mathbf{G.\ Perimeter = 2 \times (7cm+7cm) = 28cm}[/tex]
[tex]\mathbf{H.\ Perimeter = 2 \times (8cm+6cm) = 28cm}[/tex]
By comparing the options with the given perimeter, the correct dimensions are:
A. 1 cm by 6 cm
B.2 cm by 5 cm
C. 3 cm by 4 cm
D. 4 cm by 3 cm
E. 5 cm by 2 cm
F. 6 cm by 1 cm
