Solve for y
-3x + 3y = 21
Answer:
y = x + 7
Step-by-step explanation:
Your equation is -3x + 3y = 21
You want to get the y by itself (this would be easiest if you kept the y on the left side of the equation since this is where the y formally is). To do this, you need to get the -3x on the other side. Since the integer is negative, you are going to add the integer on both sides (this will cancel out the -3x on the left side since you are doing the opposite of the integer). This is shown below.
-3x + 3y = 21
+3x +3x
3y = 3x + 21
The part on the question on the right side is 3x + 21. The 3x is shown first because the x of these equations are always first. The 21 is + 21 because the 21 is already positive.
Now, we need to get the 3y to be y by itself. To do this, we need to divide the equation it total by 3. Since the 3 is attached to the y, this represents multiplication. You always want to do the opposite to do these equations. This step is shown below.
3y = 3x + 21
/3
3y divided by 3 = y
3x divided by 3 = x
21 divided by 3 = 7
Now plug these into the equation.
y = x + 7

Lalit had 10 toys and he gave 1/3 of the toys to his sister. Find the number of toys left with him.
Total number of toys with Lalit = 10
Toys he gave to his sister = 1/3 of 10.
Toys left with him = ?
Toys given = 1/3 × 10
= 10/3
= 3.33
= 3 toys (approx.)
Toys left = 10 - 3
= 7 toys (approx.)

Find the slope between:
(4,5)
(3,5)
Answer:
If a line goes through both points, the slope of that line would be [tex]0[/tex].
Step-by-step explanation:
The slope of a line is equal to the ratio between the vertical change of this line "rise" and the corresponding horizontal change "run":
[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}}\end{aligned}[/tex].
If a non-vertical line goes through two distinct points [tex](x_{0},\, y_{0})[/tex] and [tex](x_{1},\, y_{1})[/tex] where [tex]x_{0} \ne x_{1}[/tex], the vertical change (rise) would be [tex](y_{1} - y_{0})[/tex]. The corresponding horizontal change would be [tex](x_{1} - x_{0})[/tex]. Thus, the slope of that line would be:
[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}}\end{aligned}[/tex].
In this question, [tex]x_{0} = 4[/tex] and [tex]y_{0} = 5[/tex] for the first point, whereas [tex]x_{1} = 3[/tex] and [tex]y_{1} = 5[/tex] for the second point.
The rise (vertical change) of this line from the first point to the second would be [tex](y_{1} - y_{0}) = 5 - 5 = 0[/tex]. The corresponding run (horizontal change) would be [tex](x_{1} - x_{0}) = 3 - 4 = -1[/tex].
Thus, the slope of this line would be:
[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}} \\ &= \frac{5 - 5}{3 - 4} \\&= \frac{0}{-1} \\ &= 0\end{aligned}[/tex].
In other words, the slope of this line is [tex]0[/tex]. Geometrically, a slope with a slope of [tex]0\![/tex] would be horizontal. The vertical coordinate of all points on such line would be the same ([tex]5[/tex] for points on the line in this question.)

What is the distance formula and how do i do it
Answer: What is the distance formula is that it's the formula used in Mathematics such as Pre-Algebra, Algebra 1, Geometry, Algebra 2, Trigonometry, and Pre-Calculus, also Calculus to help you find the distance between 2 points in a coordinate plane or the length of a segment. How you do the distance formula is you subtract the 2nd x coordinate by the 1st one, next you add the 2nd y coordinate to the 1st one, then the answer you get you evaluate them using the exponent of 2, lastly you add that answer and square root the answer you get to the approximate or closest decimal or whole number.

Divide 5 by 1,000 and round to the nearest whole number
Answer:
1
Step-by-step explanation:
5÷1000=0.005
0.005 ≈ 1 (1 is the nearest whole number)
Hope this helps!
The number 5 divided by 1,000 is approximately 0 when rounded to the nearest whole number.
To divide 5 by 1,000, we simply perform the division:
5 ÷ 1,000 = 0.005
Now, to round the result to the nearest whole number, we examine the first decimal place. Since it is less than 5, we round down to the nearest whole number.
Thus, the rounded result is 0.
Rounding is a process used to simplify numbers to a certain level of precision. When rounding to the nearest whole number, we look at the digit to the right of the decimal point (the first decimal place). If this digit is 5 or greater, we round up to the next whole number. If it is less than 5, we round down to the current whole number.
In this case, 0.005 is less than 0.5, so we round down to 0.

Answer:
X = -1 & and for some additional information Y = -5
Step-by-step explanation:
6 x (-1) = (-6)
5 x (-5) = (-25)
(-6) - (-25) = (-31)
_____________
5 x (-1) = (-5)
3 x (-5) = (-15)
(-5) + (-15) = 10
Answer:
x = -1
Step-by-step explanation:
Rashid may have used elimination to solve the problem, but we can use any method we like to find the correct value of x. One method we like is graphing. The attached graph shows the solution is (x, y) = (-1, 5), so we know Rashid found ...
x = -1

If we go down Rashid's path, we multiply the first equation by 3 and add that to the second equation multiplied by 5. (This choice of multipliers results in a positive coefficient for x.)
3(6x -5y) +5(5x +3y) = 3(-31) +5(10)

Express v in terms of w
Answer:
[tex]v=\frac{2w}{2w-1}[/tex]
Step-by-step explanation:
[tex]w = \frac{v(1-w)}{v-2}[/tex]
Multiply both sides by (v - 2) to remove the fraction
[tex]w(v-2) = v(1-w)[/tex]
Expand both sides
[tex]vw-2w=v-vw[/tex]
Add 2w to both sides (to make the left side simpler)
[tex]vw = v - vw + 2w[/tex]
Subtract (v - vw) from both sides
[tex]vw - (v - vw)=v-vw+2w-(v-vw)[/tex]
Simplify
[tex]2vw - v=2w[/tex]
Factor 2vw - v
[tex]v(2w-1) = 2w[/tex]
Divide both sides by (2w - 1)
[tex]\frac{v\left(2w-1\right)}{2w-1} = \frac{2w}{2w-1}[/tex]
Simplify
[tex]v=\frac{2w}{2w-1}[/tex]

Answer:
Hotdog: $3
Soda: $2.50
Step-by-step explanation:
5H + 2S = 20
6H + 4S = 28
6H + 4(10 - 5/2H) = 28
6H + 40 - 10H = 28
6H - 10H =-12
H = 3
5(3) + 2S = 20
15 + 2S = 20
2S = 5
S = 2.5

Answer:
Conversion of 25m to centimeters: 2500cm
Volume is 2500m^3 (meters cubed)
Step-by-step explanation:
25m x 100cm (that's how many are in a meter) = 2500cm
Volume Formula: length x width x height (or l x w x h)
Length: 50m
Width: 25m
Height: 2m
Therefore, the volume is...
l x w x h
= 50m x 25m x 2m
= 2500m^3

In plane ABC the measure of angle A equals 42° the measure of angle B is five times the measure of angle C find the measure of angle B and the measure of angle C.
Step-by-step explanation:
I think what is meant in the triangle ABC we have the three angles.
the sum of all angles in a triangle is airways 180 degrees.
so,
180 = A + B + C
180 = 42 + B + C
now, we know also that
B = 5×C
so, we can use that above
180 = 42 + 5×C + C
138 = 6×C
C = 138/6 = 23 degrees
B = 5×C = 5×23 = 115 degrees
