Pi is an irrational and a real number
Answer:
2.8 x 10^-5
Step-by-step explanation:
Answer:
A) t = (f -v)/a
Step-by-step explanation:
Undo the operations done to t, in reverse order. Here, t is multiplied by "a" then the product is added to v.
To solve for t, first you undo the addition of v by subtracting v from both sides of the equation.
f = v + at
f - v = at . . . . . subtract v
Then you undo the multiplication by "a" by dividing both sides of the equation by "a":
(f - v)/a = t . . . . . . sort of matches choice A
_____
Please note that the parentheses are required. f -v/a is something quite different. If this is typeset, the fraction bar does the grouping. If it is written in plain text, parentheses are required for grouping.
Answer:
1. C. 4x + 40
2. a. - 2a + 10
3. d. 13x - 45
4. 2c-7d
5. b. -2z - 12
Step-by-step explanation:
1. 4(x+10) = 4x+4*10 = 4x+40
C
2. -2(a - 5) = -2*a -2*-5 = -2a+10
A
3. 10x + 3 (x-15)
10x + 3x -3*15
10x+3x-45
13x-45
D
4. -5(c+d) + 7c - 2d
-5c-5d + 7c-2d
-5c+7c -5d -2d
2c-7d
5. 2(2z + 4) - 2 (3z + 10)
2*2z +2*4 -2 *3z -2*10
4z+8 -6z-20
4z-6z+8-20
-2z-12
B
