Answer:
The statement 50π=52πh is equivalent to 50=25h. Since 50 is 25 times 2, h=2 units.
The statement 36π=r2π4 is equivalent to 36=r2⋅4. Since 36 is 4 times 9, r2=9. This implies r=3 units.

y = 2x – 1
x + y = 2
Answer:
x = 1, y = 1
Step-by-step explanation:
plug y = 2x - 1 into the equation x + y = 2:
[tex]x + (2x - 1) = 2\\3x - 1 = 2\\3x = 3\\x = 1[/tex]
plug that into the equation y = 2x - 1
[tex]y = 2*1-1\\y=2-1\\y=1[/tex]

solve 2x+6=34 i have no idea pls exsplain and help me :)
Answer:
14
Step-by-step explanation:
okay.. so basically you have 2x+6=34 right? so basically i’m gonna tell you the easiest way to do this
so you’re gonna start off by separating the 2x from the 6=34.
now that you’ve done that, let’s focus on the 6=34. so to get your answer, start by subtracting 6 from 34 so (34 - 6 = 28)
now that you’ve got that, keep the number 28 in mind. youre gonna want to take 2 and multiply by x. but 2x = 28, so what do you multiply by 2 to make 28? 14. so x is 14. to check your work, let’s see.
2 x 14 + 6 = 34?
2 x 14 = 28 + 6 = 34.
34 = 34
so, x is 14. hope this helped!

(a) Find c when d = 12
(b) Find d when c = 15
Answer:
we have
C = 1.5d
or
d=C/1.5
Step-by-step explanation:
when d is 12
C=1.5×12=18
when c=15
d=15/1.5=10

Simplify
(8x + 3)(2^2+ 8x +9)
Answer:
64x²+128x+39
Step-by-step explanation:
(8
Answer:
First distribute (8x + 3) into (2^2+ 8x +9)
16x^3 + 64x^2 + 72x + 6x^2 + 24x +27
Then we'll order the pairs from highest to lowest degree
16x^3 + 64x^2 + 6x^2 + 72x + 24x + 27
Then we'll add up the like terms
16x^3 + 70x^2 + 96x + 27
That should be your final answer simplified.

Find f (-12) if f (x) = -12x + 100
f(-12) = -12(-12) + 100 = 144 + 100 = 244
Answer:
244
Step-by-step explanation:
Substitute -12 as x.
f (-12) = -12(-12) + 100
f (-12) = 144 + 100
f (-12) = 244

y=−2x+4 missing value ( - , -2)
30 points
Answer: Y=4
Step-by-step explanation:
Answer:
The missing value is 3.
Step-by-step explanation:
I plugged in -2 as y.
-2 = -2x+4
-2 -4 = -2x -4
-6 = -2x
-6/-2 = -2x/-2
3 = x
So the point is (3, -2)

A line is parallel to y = 4x + 1 and
intersects the point (-2,-5). What is the
equation of this parallel line?
y = [?]x + [
Answer:
y = 4x+3
Step-by-step explanation:
The equation in point slope form is expressed as y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
If a line is parallel to y = 4x + 1, the slope of the line m = 4
Substitute m = 4 and the point (-2, -5) into the equation above;
y - (-5) = 4(x - (-2))
y+5 = 4(x+2)
y+5 = 4x+8
y = 4x+8-5
y = 4x + 3
Hence the equation of the line is y = 4x+3

In ∆PQR, if m∠P=x–12,m∠Q=5x–27, and m∠R=2x+3, write an equation and solve for x. x =
Answer:
∠p= 15° , ∠q = 108° , ∠r = 57° Is the Answer
Step-by-step explanation:
, (x -12)° + (5x-27)° + (2x + 3)° = 180°
or, 8x° -36° = 180°
Or x =
So, x = 27°
∴ ∠P = 27° -12° = 15°
∠q = (5 × 27)° -27° = 108°
∠r = (2 × 27)° + 3° = 57°

The test will cover 120 pages in his textbook. He has read only 36 pages. If he plans to read an equal amount every day of the week to finish the 120 pages, how much must read each day?
Answer:
He must read each day=12 pages
Step-by-step explanation:
We are given that
Total number of pages in textbook=120
He has read number of pages=36
Number of days in a week=7
We have to find the number of pages read each day to finish 120 pages in a week.
Number of pages remaining for reading=120-36
Number of pages remaining for reading=84
Now,
Number of pages read each day=[tex]\frac{84}{7}[/tex]
Number of pages read each day=12
Hence, he must read each day=12 pages
