[tex]s = \frac{w - 10e}{m} [/tex]
I'm trying to solve for w
9514 1404 393
Answer:
w = ms +10e
Step-by-step explanation:
The basic idea is to undo what is done to w. Here, 10e is subtracted, and the difference is divided by m. We undo these in reverse order. To undo the division, we multiply by m. To undo the subtraction, we add the quantity that was subtracted. Any operation that we perform must be done to both sides of the equation.
[tex]s = \dfrac{w - 10e}{m}\qquad\text{given}\\\\ms=w-10e\qquad\text{multiply by $m$}\\\\ms+10e=w\qquad\text{add $10e$}[/tex]
Usually, you want to write that with w on the left:
w = ms +10e

Find the slope of the line that passes through (10, 63) and (94, -7).
Answer:
The slope is [tex]-\frac{5}{6}[/tex]
Step-by-step explanation:
Hi there!
We are given two points: (10, 63) and (94, -7)
We want to find the slope that passes through these lines
We can use the slope formula to find it
The formula for slope calculated from two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything needed to find the slope, let's just label their values to avoid confusion:
[tex]x_1=10\\y_1=63\\x_2=94\\y_2=-7[/tex]
Now substitute these values into the formula:
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-7-63}{94-10}[/tex]
Subtract the numbers:
m=[tex]\frac{-70}{84}[/tex]
Divide:
m=[tex]-\frac{5}{6}[/tex]
The slope of the line is [tex]-\frac{5}{6}[/tex]
Hope this helps!
What is the value of x and y in the following figure?
Answer:
Step-by-step explanation:
x = 75°
75° + 75° + a = 180°
a + 150° = 180°
a = 180° - 150°
a = 30°
y + 30° = 90°
y = 90° - 30°
y = 60°
I hope I've helped you
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The required values are ~
[tex] \boxed{x = 75 \degree}[/tex]
and
[tex] \boxed{y = 60 \degree}[/tex]
[tex] \large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}[/tex]
As it's shown in the figure, the sides opposite to x and Angle 75° are equal. So the corresponding Angles are also equal to one another.
that is ~
[tex]x = 75 \degree[/tex]I have taken an angle and marked it as " m " in the attachment.
So, according to Angle sum property of a triangle,
[tex]m + x + 75 \degree = 180 \degree[/tex][tex]m + 75 \degree+ 75 \degree= 180 \degree[/tex][tex]m + 150 \degree= 180 [/tex][tex]m = 180 \degree - 150 \degree[/tex][tex]m = 30 \degree[/tex]now, it's given that the sum of Angle y and Angle m is 90°
hence,
[tex]m + y = 90 \degree[/tex][tex] 30 \degree + y = 90 \degree[/tex][tex]y = 90 \degree - 30 \degree[/tex][tex]y = 60 \degree[/tex]Someone plz help me :(

Find the values of x and y that make the quadrilateral a parallelogram. (4x + 13) (4y + 7)º (3x - 8) (5x - 12)
The sum of angles in a parallelogram adds up to 360 degrees
The values of x and y are 25 and 15, respectively.
The angles are given as:
[tex]\mathbf{\angle 1 = 4x + 13}[/tex]
[tex]\mathbf{\angle 2 = 4y + 7}[/tex]
[tex]\mathbf{\angle 3 = 3x - 8}[/tex]
[tex]\mathbf{\angle 4= 5x - 12}[/tex]
The opposite angles of a parallelogram are equal.
So, we have:
[tex]\mathbf{4x + 13 = 5x - 12}[/tex]
Collect like terms
[tex]\mathbf{5x - 4x = 13 + 12}[/tex]
[tex]\mathbf{x = 25}[/tex]
Simiarly, we have:
[tex]\mathbf{4y + 7 = 3x -8}[/tex]
Substitute 25 for x
[tex]\mathbf{4y + 7 = 3 \times 25 -8}[/tex]
[tex]\mathbf{4y + 7 = 75 -8}[/tex]
[tex]\mathbf{4y + 7 = 67}[/tex]
Subtract 7 to both sides
[tex]\mathbf{4y = 60}[/tex]
Divide both sides by 4
[tex]\mathbf{y = 15}[/tex]
Hence, the values of x and y are 25 and 15, respectively.

Step-by-step explanation:
Find common denominator
[tex]\frac{d}{3} +\frac{3*9.9}{12.9}[/tex]
Combine fractions with common denominator
[tex]\frac{d+3*9.9}{3} =12.9[/tex]
Multiply the numbers
[tex]\frac{d+29.7}{3} =12.9[/tex]
Multiply all terms by the same value to eliminate fraction denominators
[tex]3(\frac{x+29.7}{3} )=3 * 12.9[/tex]
Cancel multiplied terms that are in the denominator
x=29.7= 3 · 12.9
Multiply the number
x= 12.9=38.9
Subtract 297 from both sides of the equation
x+29.7-29.7=38.9-29.7
Simplify
x = 9.0
Hence, the answer is 9.

A game lasts 5/8 hours. Jane played 4 of these games.
For how long did she play in total?
Answer: 2 hours 30 minutes in total.
Step-by-step explanation: Because when it says that a game lasts for 5/8 hours and Jane only play 4 of these games, Which means that you have to multiply the number of hours lasted by the total number of games that have been played. Therfore 5/8 x 4 = 20/8 but you simplify your answer and you will get 2 hours and 30 minutes in total.
