Step-by-step explanation:
7x - 4 = 5x + 12
7x - 5x - 4 = 5x - 5x + 12
2x - 4 = 12
2x - 4 + 4 = 12 + 4
2x = 16
2x/2 = 16/2
x = 8

2x = 5y + 14
x = 5y
Answers
Answer:
y = 2.8x = 14Step-by-step explanation:
To solve an equation, we can only have one variable. In this case, we are given the system 2x = 5y + 14. However, we are given the value of x in terms of y. We can substitute 10y in for 2x and solve.
10y = 5y + 14
First, we need to get all the variables on one side of the equation, so we subtract 5y.
5y = 14
Divide by 5
y = 14/5 or 2 4/5 or 2.8
Now for the x part.
2x = x + 14
Subtract 1x
x = 14
Now we check our answer.
2(14) = 5(2.8) + 14
28 = 14 + 14
28 = 28
Because 28 equals 28, our solutions are correct.
Grayson just lit a new candle and then let it burn all the way down to nothing. The candle burned at a rate of 0.75 inches per hour and its initial length was 12 inches. Make a table of values and then write an equation for L,L, in terms of t,t, representing the length of the candle remaining unburned, in inches, tt hours after the candle was lit.
Answers
Step-by-step explanation:
In this example, I made h height.
For this situation, you would use y=mx+b.
If we use this formula, m would be slope. 1.5 is the slope and we are decreasing the size of the candle, which makes -1.5.
x would be t because that's the independent variable.
Since the initial height was 15 inches, 15 would be our starting point or y-intersept, which is b.
So if you put that together, you get h=-1.5t+15.
You can rearrange that to the answer above.

Answer:
Equation: y = 1/5x - 2
Slope (m): 1/5
The graph of the line equation y = 1/5x - 2 is also attached below.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the ordered pairs
(5, -1)(-5, -3)Finding the slope between the points (5, -1) and (-5, -3)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-5,\:-3\right)[/tex]
[tex]m=\frac{-3-\left(-1\right)}{-5-5}[/tex]
Refine
[tex]m=\frac{1}{5}[/tex]
Thus, the slope (m) = 1/5
Also given that the y-intercept b = -2
Now, substituting m = 1/5 and y-intercept b = -2 in the slope-intercept form
y = mx+b
y = 1/5x + (-2)
y = 1/5x - 2
Therefore, the equation of the line is:
y = 1/5x - 2The graph of the line equation y = 1/5x - 2 is also attached below.

Right triangle ABC is similar to right triangle DEF. If the side lengths for triangle ABC are 15, 20, 25, respectively, which values could represent the side lengths of triangle DEF
Answers
Answer:
[tex]A = 15[/tex] [tex]B = 20[/tex] [tex]C = 25[/tex]
[tex]D = 30[/tex] [tex]E = 40[/tex] [tex]F = 50[/tex]
[tex]D = 3[/tex] [tex]E = 4[/tex] [tex]F = 5[/tex]
Step-by-step explanation:
Given
Similar Triangles: ABC and DEF
[tex]A = 15[/tex]
[tex]B = 20[/tex]
[tex]C = 25[/tex]
Required
Determine the sides of DEF
No options were given, so I will solve on a general terms.
Since both triangles are similar, then the following relationship exists.
DEF = ABC * n
i.e.
[tex]D = A * n[/tex] [tex]E = B * n[/tex] [tex]F = C * n[/tex]
Where
[tex]n = Scale\ Factor[/tex]
Assume n = 2.
So, we have:
[tex]D = A * n[/tex]
[tex]D =15 *2[/tex]
[tex]D = 30[/tex]
[tex]E = B * n[/tex]
[tex]E = 20 * 2[/tex]
[tex]E = 40[/tex]
[tex]F = C * n[/tex]
[tex]F = 25 * 2[/tex]
[tex]F = 50[/tex]
Assume [tex]n = \frac{1}{5}.[/tex]
So, we have:
[tex]D = A * n[/tex]
[tex]D =15 *\frac{1}{5}[/tex]
[tex]D = 3[/tex]
[tex]E = B * n[/tex]
[tex]E = 20 * \frac{1}{5}[/tex]
[tex]E = 4[/tex]
[tex]F = C * n[/tex]
[tex]F = 25 * \frac{1}{5}[/tex]
[tex]F = 5[/tex]
So, the possible sides are:
[tex]A = 15[/tex] [tex]B = 20[/tex] [tex]C = 25[/tex]
[tex]D = 30[/tex] [tex]E = 40[/tex] [tex]F = 50[/tex]
[tex]D = 3[/tex] [tex]E = 4[/tex] [tex]F = 5[/tex]

Solve for h.
h/10 + 5 = 25
so what’s h ??
Answers
Answer:
h=200
Step-by-step explanation:
h/10+5=25
h/10=20
h=200
h/10 + 5 = 25
Subtract 5 from each side to get h/10 alone.
h/10 + 5 - 5 = 25 - 5
h/10 = 20
Multiply both sides by 10 to get h alone.
h/10 • 10 = 20 • 10
h = 200
h = 200. I hope this helps!
