Solve for r.
18r - 10r - 20r + 2r + 9r = 18
r =
Submit
Answer:
[tex]r=-18[/tex]
Step-by-step explanation:
1) Combine like terms
[tex]18r-10r-20r+2r+9r=18\\-r=18[/tex]
2) Divide both sides of the equation by the same term
[tex]-r=18\\\frac{-r}{-1} =\frac{18}{-1}[/tex]
3) Simplify
a. Cancel terms that are in both the numerator and denominator
[tex]\frac{-r}{-1} =\frac{18}{-1} \\r=\frac{18}{-1}[/tex]
b. Divide the numbers
[tex]r=-18[/tex]
Answer: -18
Step-by-step explanation:
18r - 10r - 20r + 2r + 9r = 18
-r = 18
18/-1
r = -18

64
Step-by-step explanation:
Let the missing side be " x "
30 / ( 30 + 10 ) = 48 / x.
30 / 40 = 48 / x
3 / 4 = 48 / x
3 * x = 4 * 48
x = 4 * 48 / 3
= 4 * 16
x = 64
solve pls brainliest
Step-by-step explanation:
to solve it you will first change it to an improper fraction by multiplying 29 and 4 and adding 3 to the answer.after changing to an improper fraction you will have to divide the numerator which is 119 by the denominator 4.to divide 119 by 4 you will have to use the long division method so that you will get your answer.A pole that is 3.1m tall casts a shadow that is 1.74m long. At the same time, a nearby building casts a shadow that is 46.5m long. How tall is the building? Round your answer to the nearest meter.
Answer:
The building is approximately 82.844 or 83 meters tall
Step-by-step explanation:

Later, he gave four to each of his friends. He only has 4 remaining. How many friends does he have?
Answer:
He has 19 friends
Step-by-step explanation:
If he won 80 bouncy balls and at the end he is left with four we can subtract 4 from 80 to get 76 and then since we know that he gave 4 to each of his friends we can then divide 76 by 4 to get 19.

Find the area of this figure to the nearest hundredth. Use 3.14 to approximate pi.
(The figure is a right triangle conjoined to a semi-circle. The semi-circle's diameter is 8, the triangle's base is 6, the triangle's height is 8. )
Answer:
49.12 square units
Step-by-step explanation:
Area of triangle = [tex]\dfrac{1}{2}*base *height[/tex]
[tex]=\dfrac{1}{2}*6*8=3*8 = 24 \ sq.units[/tex]
Circle:
d = 8 units
r = 8/2 = 4 units
[tex]Area \ of \ semicircle = \dfrac{1}{2}\pi r^{2}\\[/tex]
[tex]=\dfrac{1}{2}*3.14*4*4=3.14*2*4= 25.12 \ sq.units[/tex]
Area of the figure = area of triangle +area of semicircle
= 24 + 25.12
= 49.12 sq. units

Answer:
y=8x+3
Step-by-step explanation:
to check plug the numbers to the equation and you will that it is right
Answer:
f(x) = 8x + 3
Explanation:
I knew f(x) = mx +b is the formula for a linear equation and that when x = 0,
f(x) = b
So, when x = 0 in the table, f(x) = 3 and therefore b = 3
Now we can plug in f(x) = 11 and x =1 into f(x) = mx+b along with our b value
11 = m(1) + 3
solving for m we get m = 8 which finishes our unknowns
f(x) = mx + b
f(x) = 8x + 3

To tie-dye one T-shirt 3/8 cup of dye is needed. the table shows the number of cups of each color of dye in Mr. Galvez's art class. how many t-shirts can be made using only orange dye?
Amount of Dye
red: 12
orange:3/4
Answer:
Two shirts can be made
Step-by-step explanation:
We do have 3/4c of orange dye.
We do require 3/8c per T-shirt.
But, using math, it can be shown that 3/4c=2×3/8c
Looking at it this way: 3/4c = 2x3/8c
Where the 2 is the number of T-shirts we can produce.
It is easy now to see: 3/4c = 2x3/8c = 6/8c
So: 34c=68c=34c→ and all of this is orange dye

Answer:
dy/dx = (2 -x)/40.005Step-by-step explanation:
(a) Solving the x-equation for u gives ...
u = (x -1)/4
Differentiating both equations with respect to u, we have ...
dy/du = 1 -4u
dx/du = 4
Then dy/dx is ...
dy/dx = (dy/du)/(dx/du) = (1 -4u)/4
Substituting for u gives ...
dy/dx = (1 -4(x -1)/4)/4
dy/dx = (2 -x)/4
__
(b) The approximate change in y is ...
∆y ≈ (dy/dx)(∆x)
For ∆x = 2.98 -3.00 = -0.02, and x=3, the approximate change is ...
∆y ≈ (2 -3)/4(-0.02)
∆y ≈ 0.005
