Answer:
No solution
Step-by-step explanation:
3(5x+7) = 30 + 15x
DISTRIBUTE
15x+21 = 30+15x
15x-15x = 0
So no solution
Answer:
Which expression is equivalent to one over three p + 15? (4 points)
one over three (p + 45)
one over three (p + 5)
<u>3(p + 45) </u>
3(p + 5)
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
1. Distributive Property
(Do what's in the parenthesis first)
4x - 2x + 6 = -4 + 5x - 5
2. Combine Like Terms
2x + 6 = -9 + 5x
3. Take away 6 on both sides
2x + 6 - 6 = -9 - 6 +5x
It will give u.....
2x = -15 + 5x
4. Subtract 5x on both sides
2x - 5x = -15
It will give u.....
-3x = -15
5. Divide by -3 on both sides to isolate the variable
-3x / 3 = -15/-3
Now you get....
x = 5
2 negatives make a positive
Thats ur answer
Hope this helped!
Answer:
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.
Answer:
165
Step-by-step explanation:
formula is
nCr = n!/(r!(n−r)!)
r= 8 = number of choosing objects from the set
n = 11 = total number of objects in the set
C(n,r)=C(11,8)
=11!/(8!(11−8)!)
! means factorial
factorial means to multiply by decreasing positive numbers.
For example, 8! = 8 ∗ 7 ∗ 6 ∗ 5 ∗ 4 ∗ 3 ∗ 2 ∗ 1 = 40320
=11!/8!×3!
= 165
