Step-by-step explanation:
how do u solve this its pre-algebra 4x – 5y = 20
Answer:
x = 5 + 5y/4
Step-by-step explanation:
I think its like this: 4x - 5y = 20
Add 5y to both sides: 4x = 20 + 5y
Divide both sides by 4: x = 20/4 + 5y/4
Simplify: x = 5 + 5y/4
I'm pretty sure it is like this

The measure of angle B in a triangle is 4 more than twice the measure of angle A. The measure of angle C is 30 less than 3 times the measure of angle A. Find the measure of each angle.
Answer:
[tex]A = 34\frac{1}{3}[/tex]
[tex]B = 72\frac{2}{3}[/tex]
[tex]C = 73[/tex]
Step-by-step explanation:
Given
Shape: Triangle
[tex]B = 4 + 2A[/tex]
[tex]C = 3A - 30[/tex]
Required
Solve for A, B and C
Since the shape is a triangle,
[tex]A + B +C = 180[/tex]
Substitute [tex]B = 4 + 2A[/tex] and [tex]C = 3A - 30[/tex] in [tex]A + B +C = 180[/tex]
[tex]A + 4 + 2A + 3A - 30 = 180[/tex]
Collect Like Terms
[tex]A + 2A + 3A = 180 + 30 - 4[/tex]
[tex]6A = 206[/tex]
Solve for A
[tex]A = 206/6[/tex]
[tex]A = 34\frac{1}{3}[/tex]
Substitute [tex]A = 34\frac{1}{3}[/tex] in [tex]B = 4 + 2A[/tex]
[tex]B = 4 + 2 * 34\frac{1}{3}[/tex]
[tex]B = 4 + 2 * \frac{103}{3}[/tex]
[tex]B = 4 + \frac{206}{3}[/tex]
[tex]B = \frac{12 + 206}{3}[/tex]
[tex]B = \frac{218}{3}[/tex]
[tex]B = 72\frac{2}{3}[/tex]
Substitute [tex]A = 34\frac{1}{3}[/tex] in [tex]C = 3A - 30[/tex]
[tex]C = 3 * 34\frac{1}{3} - 30[/tex]
[tex]C = 3 * \frac{103}{3} - 30[/tex]
[tex]C = 103 - 30[/tex]
[tex]C = 73[/tex]

Answer:
[tex]\frac{2}{3} x + \frac{1}{3} - \frac{1}{3} x = \frac{1}{3} ( x - 1)\\\\ \\\frac{4}{3}x - \frac{4}{3} - \frac{2}{3} = \frac{4}{3} ( x - 1)\\\\( \frac{1}{3} x + \frac{2}{3} ) + ( -\frac{2}{3}x - \frac{4}{3}) = -\frac{1}{3} ( x + 2)\\\\(\frac{2}{3}x + \frac{1}{3} ) + (\frac{2}{3} x - \frac{2}{3} ) = \frac{1}{3} ( 4x - 1 )[/tex]
Step-by-step explanation:
Simplify each equation by combining like terms, and then factoring
[tex]\frac{2}{3} x + \frac{1}{3} - \frac{1}{3} x[/tex]
= [tex]\frac{1}{3} x + \frac{1}{3}[/tex]
= [tex]\frac{1}{3}[/tex] ( x + 1)
[tex]\frac{4}{3}x - \frac{4}{3} - \frac{2}{3}[/tex]
= [tex]\frac{4}{3}x - \frac{6}{3}[/tex]
= [tex]\frac{4}{3}[/tex] ( x - 1 )
[tex]\ ( \frac{1}{3} x + \frac{2}{3} ) + ( -\frac{2}{3}x - \frac{4}{3})[/tex]
=[tex]-\frac{1}{3}x - \frac{2}{3}[/tex]
=[tex]- \frac{1}{3} x[/tex] ( x + 2)
[tex]\ (\frac{2}{3}x + \frac{1}{3} ) + (\frac{2}{3} x - \frac{2}{3} )[/tex]
= [tex]\ \frac{4}{3}x - \frac{1}{3}[/tex]
= [tex]\(\frac{1}{3}[/tex] ( 4x - 1)
Answer:
Step-by-step explanation:
[tex]1)\frac{2}{3}x + \frac{1}{3}-\frac{1}{3}x = \frac{2}{3}x-\frac{1}{3}x +\frac{1}{3}\\\\\\=\frac{(2-1)}{3}x+\frac{1}{3}\\\\\\=\frac{1}{3}x+\frac{1}{3}\\\\\\=\frac{1}{3}(x+1)[/tex]
[tex]2) \frac{4}{3}x-\frac{2}{3}-\frac{2}{3}=\frac{4}{3}x + \frac{(-2-2)}{3}\\\\\\[/tex]
[tex]=\frac{4}{3}x -\frac{4}{3}\\\\\\=\frac{4}{3}(x-1)[/tex]
[tex]3) (\frac{1}{3}x+\frac{2}{3})+(\frac{-2}{3}x-\frac{4}{3})=\frac{1}{3}x-\frac{2}{3}x+\frac{2}{3}-\frac{4}{3}[/tex]
[tex]= \frac{-1}{3}x-\frac{2}{3}\\\\\\=\frac{-1}{3}(x+2)\\[/tex]
4) [tex](\frac{2}{3}x +\frac{1}{3})+(\frac{2}{3}x-\frac{2}{3})=\frac{2}{3}x+\frac{2}{3}x+\frac{1}{3}-\frac{2}{3}[/tex]
[tex]=\frac{4}{3}x-\frac{1}{3}\\\\\\=\frac{1}{3}(4x-1)[/tex]
All I need is the slope and the equation also the y-intercept to help please!
Answer:
1) Slope; -10
Y-intercept; (0,60)
Equation; y=−10x+60
2) Slope;-1/2
Y-intercept; (0,0)
Equation; y=−1/2x
Step-by-step explanation:
Use the slope formula and slope-intercept form y=mx+b to find the equation.
Answer:
1.)
slope: -10
y-intercept: 60
equation: [tex]y=-10x+60[/tex]
2.)
slope: [tex]-\frac{1}{2}[/tex]
y-intercept: 0 (the line passes through the origin)
equation: [tex]y=-\frac{1}{2} x[/tex]
Explanation:
To find your slope you can use the equation [tex]\frac{y_{2}-y_1 }{x_2-x_1}[/tex], plugging in the designated numbers from two ordered pairs you select from the chart.
Your y-intercept is the value found at y whenever x is equal to 0.
For your equation, you simply place your slope in front of x and add on your y-intercept.

Step-by-step explanation:
I'm not sure exactly what you are asking for but here is what the box plot tells you:
Minimum is 17 items.
Q1 (Lower Quartile) is 22 items. So, 25% of the customers bought 22 items.
Q2 (Median) is 32 items. So, 50% of the customers bought 32 items.
Q3 (Upper Quartile) is 35 items, So, 75% of the customers bought 35 items.
Maximum is 62 items.
The data is "heavier" on the right so it is skewed left.
Range is 62 - 17 = 45
IQR (Interquartile range) is Q3 - Q1 = 35 - 22 = 13

An angle is 1/3 the measure of its complement. What is the measure of the angle, the complement and the supplement?
Answer:
Angle: 22.5 deg, Complement: 67.5 deg, Supplement: 157.5 deg
Step-by-step explanation:
22.5 is 1/3 of 67.5
so compliment is 67.5.
Supplement is just adding another angle so I chose 7.
I did 22.5 x 7 = 157.5
Another example would be:
Angle: 10 deg, Complement: 30 (because 10 x 3), Supplement: 70 (because 10 x 7)

Sequence: 49, 36, 25, 16, 8, 4, 1 * Is this a arithmetic or geometric sequence? and if it is arithmetic find the common difference and if it is geometric find the common ratio? and please do not give me a stupid answer only smart people answer this if you know the answer to this you are smart.
Answer:
Step-by-step explanation:
The sequence is nor properly written. This is correct sequence
49, 36, 25, 16, 9, 4, 1...
Merely looking at the sequence, we can see that it doesn't form an arithmetic sequence nor does it form a geometric sequence.
The values of the sequence are all perfect squares.
Rewriting the sequence;
7², 6², 5², 4², 3², 2², 1²...
Now we can see that the base values for an arithmetic sequence as shown:
7, 6, 5, 4, 3, 2, 1...
We find the common difference of this sequence as shown
d = T2-T1 = T3-T2 = T4-T3
Given T1 = 7, T2 = 6, T3 = 5, T4 = 4
Substitute
d = 6-7 = 5-6 = 4-5 = -1
d = -1
Get the nth term using the sequence
Tn = a+(n-1)d
a is the first term
d is the common difference
n is number of terms
Tn = 7+(n-1)(-1)
Tn = 7+(-n+1)
Tn = 7+1-n
Tn = 8-n
Since their power are constant i.e squared, hence we will square the ntj term as well to get the nth term of the original sequence as;
Tn = (8-n)²
To conclude, we can say that the sequence is neither arithmetic nor geometric sequence since the terms of the sequence are prefect squares.

Answer:
Scale = ¼
Step-by-step explanation:
See attachment for complete question.
In the attached, we have.
Width = 4 units. ----- Orange
Width = 16 units ------- Black

Determine the scale of dilation
The scale of dilation can be calculated as:
Scale = Width(orange)/Width (black)
Scale = 4/16
Scale = ¼
Hence, the scale of dilation is ¼
