Answer:
Step-by-step explanation:
j=k+4
k=3r
j=3r+4
j+k+r=46
3r+4+3r+r=46
7r+4=46
7r=42
r=6, since k=3r
k=18, since j=k+4
j=22
j,k,r=22,18,6

Answer:
The answer is going to be C- 4(5c - 2d)
Step-by-step explanation:
Because:
You need to distribute first so,
4* 5c = 20c
and
4*-2d = - 8d
So, that would be equivalent to 20c - 8d :)
What is the value of 8m + 5n when m = 4 and n = 10?

Carter needs to remove sod in his yard to build three flower beds. One bed will be a rectangle which measures 2.5 m by 6 m. Another bed will be a semicircle which has a diameter of 6 m. The other bed will be a quarter circle with a radius of 4 m.
Answer:
[tex]Area = 41.714[/tex][tex]m^2[/tex]
Step-by-step explanation:
Given
Rectangle:
[tex]Length = 2.5m[/tex]
[tex]Width = 6m[/tex]
Semicircle
[tex]Diameter = 6m[/tex]
Quarter circle
[tex]Radius = 4m[/tex]
Required
The square meters of sod will Carter remove [Missing information]
To do this, we simply calculate the area of each flower beds.
For the rectangle:
[tex]A_1= Length * Width[/tex]
[tex]A_1= 2.5m * 6m[/tex]
[tex]A_1= 15m^2[/tex]
For the semicircle
[tex]A_2 = \frac{1}{2}\pi r^2[/tex]
Where
[tex]r=\frac{6}{2} = 3[/tex]
So:
[tex]A_2 = \frac{1}{2} *\frac{22}{7} * 3^2[/tex]
[tex]A_2 = \frac{1}{2} *\frac{22}{7} * 9[/tex]
[tex]A_2 = \frac{1*22*9}{2*7}[/tex]
[tex]A_2 = \frac{198}{14}[/tex]
[tex]A_2 = 14.143[/tex]
For the quarter circle
[tex]A_3 = \frac{1}{4}\pi r^2[/tex]
[tex]A_3 = \frac{1}{4} * \frac{22}{7} * 4^2[/tex]
[tex]A_3 = \frac{22}{7} * 4[/tex]
[tex]A_3 = \frac{88}{7}[/tex]
[tex]A_3 = 12.571[/tex]
Total area is:
[tex]Area = A_1 + A_2 + A_3[/tex]
[tex]Area = 15 + 14.143 + 12.571[/tex]
[tex]Area = 41.714[/tex][tex]m^2[/tex]

The formula for converting miles into feet is F = 5280m. If m = 12, evaluate this to find F, how many feet are in 12 miles. (Write the full equation, and then substitute for m.) *
Answer:
63360 feet
Step-by-step explanation:
The formula for converting miles into feet is F = 5280m. If m = 12, evaluate this to find F, how many feet are in 12 miles. (Write the full equation, and then substitute for m.) *
From the above question, we are given the expression:
F = 5280m
Where
F = Number of miles in feet
If m = 12 miles, the number of feet is calculated as:
F = 5280 × 12 miles
F = 63360 feet
Find a ⋅ b.
a = 9i + 5j, b = 4i + 3j
A line passes through the given points. Write an equation for the line in point-slope form. Then rewrite the equation in slope-intercept form. (1 , 1/2), (3, 2)
A) y + 1/2 = 3/4 ( x + 1 ) ; y = 3/4x + 1/4
B) y − 1/2 = 3 ( x − 1 ) ; y = 3x − 1/4
C) y − 1/2 = 3/4 ( x − 1 ) ; y = 3/4x − 1/4
Answer: C
Step-by-step explanation:
Find Slope first
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{2-.5}{3-1}[/tex]
[tex]m=1.5/2\\m=3/4[/tex]
Slope is 3/4
Chose a point to put in point slope form
(1,1/2)
y − y1 = m(x − x1)
[tex]y-\frac{1}{2} =\frac{3}{4} (x-1)[/tex]
[tex]y-\frac{1}{2} = \frac{3}{4}x-\frac{3}{4}[/tex]
add 1/2 to both side
Add (a+b-3)+(b+2a-1)+(4-6b+2a)
Answer:
[tex](a + b - 3) + (b + 2a - 1) + (4 - 6b + 2a)[/tex]
=
[tex]a + 2a + 2a + b + b - 6b - 3 - 1 + 4[/tex]
[tex]5a - 4b - 4 + 4[/tex]
[tex] = 5a - 4b + 0[/tex]
[tex] = 5a - 4b[/tex]
have nice day

give me thanks
PLS DO BOTH PROBELMS
1.) 510 miles
Take the values you have been given which is 153 miles and 3 gallons of gas
Now divide 153 by 3 to find put the Miles per gallon (MPG)
153/3=51
now take 51 and multiply it by 10
51x10=510
2.) $16 per yard of plywood
Let's take the values we have been given
3/4 of a yard of plywood and $12 for it
Now let's divide it
