Answer:
Step-by-step explanation:
if you multiplied a number by 3, you would get 51. If you want to solve for x, divide on both sides of the equal sign.
51/3 = 3x/3
17=x
Answer: 17
Step-by-step explanation: X is your variable, you need to find what X equals
In this case you can divide
51/3= 17
You can plug in your result to check your work. If the equation is true, it is correct
Since 51= 3 x 17, or 3 x 17= 51, this is correct

Find the inequality represented by the graph
Answer:
y > -2/3 x + 3
Step-by-step explanation:
First we find the equation of the dashed line.
y = mx + b
We see b = 3.
The slope is -2/3.
The equation of the line is
y = -2/3 x + 3
The line is dashed, not solid, and the shading is above the line, so the inequality is
y > -2/3 x + 3
Which one of the following equations represents a circle with its center of origin?
A) x^2 + y^2 = 5
B) x^2 + y = 25
C) x + y = 5
D) x/2 + y/2 = 25
Answer:
A) x² + y² = 5Step-by-step explanation:
The equation of the circle:
(x - h)² + (y - k)² = r²The center is (h, k)
Wen the center is the origin we have, h = 0, k = 0:
x² + y² = r²The only equation in same format is the first one
29. The circumference of a circle is C centimeters. The diameter of the circle is 13
centimeters.
Which expression best represents the value of ar?
Answer:If the diameter is 13 you should try each answer until you find pi.
To find pi you have to divide the circumference by the radius.
You don't need to find the circumference in this question but you can.
The circumference is 40.82
Then you have to divide
40.82÷13
that equals 3.14
and because that is pi, C is your answer

At a glance, Kendra believes that the function represented on the graph is linear.
How can Kendra determine if the function is actually linear?
She can check to see if the rate of vertical increase equals the rate of horizontal increase between each pair of points.
She can check to see if the sum of each y-value and x-value in every ordered pair is the same.
She can check to see if the quotient of each y-value and x-value in every ordered pair is the same.
She can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs.

The value of a bank account, B, after x years is represented by the equation B = 1000(1+.014)x. To the nearest penny, how much is the account worth after 15 years?
Answer:
1232 penny
Step-by-step explanation:
Given the value of a bank account, B, after x years is represented by the equation B = 1000(1+.014)^x.
To determine the account worth after 15 years, we will substitute x = 15 into the expression as shown;
B = 1000(1+.014)^x.
B = 1000(1+.014)^15
B = 1000(1.014)^15
B = 1000(1.2319)
B = 1231.9penny
Hence the value after 15years is 1232 penny (to the nearest penny)

A Rectangular has area 12a^2 and perimeter 14a what are the dimensions of this Rectangular?
9514 1404 393
Answer:
3a by 4a
Step-by-step explanation:
For dimensions L and W, the area and perimeter are ...
A = LW = 12a^2
P = 2(L+W) = 14a
Using the second equation, we can find L:
L +W = 7a . . . . . divide by 2
L = 7a -W
Substituting into the area formula gives the quadratic ...
(7a -W)(W) = 12a^2
W^2 -7aW +12a^2 = 0 . . . . arrange in standard form
(W -3a)(W -4a) = 0 . . . . . . . factor (find factors of 12 that total 7)
Then we have the two solutions ...
W = 3a, L = 4a
W = 4a, L = 3a
The rectangle dimensions are 3a by 4a.

hi, i need help with Solve 18>12+x. Graph the solution.
Answer:
x < 6
Step-by-step explanation:
18 > 12 + x
Switch sides:
12 + x < 18
Subtract 12 from both sides:
12 + x - 12 < 18 - 12
x < 6
The solution of the inequality is,
⇒ x < 6
And, Graph is shown in image.
What is mean by Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The inequality is,
⇒ 18 > 12 + x
Now, We can solve the inequality as;
⇒ 18 > 12 + x
Switch sides:
⇒ 12 + x < 18
Subtract 12 from both sides:
⇒ 12 + x - 12 < 18 - 12
⇒ x < 6
Thus, The solution of the inequality is,
⇒ x < 6

Brainiest answer to whoever is correct
Answer:
Required amount of aluminium foil = 522.80 [tex]in^{2}[/tex]
Step-by-step explanation:
The shape of the large Hershey kisses can be compared to that of a cone. So that;
the surface area of the kisses = [tex]\pi[/tex][tex]r^{2}[/tex] + [tex]\pi[/tex]rl
Let the slant height be represented by l. Applying the Pythagoras theorem;
[tex]l^{2}[/tex] = [tex]10^{2}[/tex] + [tex]8^{2}[/tex]
= 100 + 64
= 164
l = [tex]\sqrt{164}[/tex]
l = 12.81 in
Thus,
surface area of the kisses = (3.14 x [tex]8^{2}[/tex]) + (3.14 x 8 x 12.81)
= 200.96 + 321.7872
= 522.7472
surface area of the kisses = 522.75 [tex]in^{2}[/tex]
Thus, the amount of aluminium foil required to wrap the kisses is 522.80 [tex]in^{2}[/tex].

3x + 265 = 4
Answer:
x = -87
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, subtract 265 from both sides of the equation:
3x + 265 (-265) = 4 (-265)
3x = 4 - 265
3x = -261
Next, divide 3 from both sides:
(3x)/3 = (-261)/3
x = -261/3
x = -87
x = -87 is your answer.
~
Answer:
If you're looking for the value of x, it's -87.
Step-by-step explanation:
1. Subtract 265 from both sides
3x+265-265 = 4-265 = 3x = -261
2. Divide by 3 to get the variable by itself
3x/3 = -261/3. = -87
x = -87
