Answer:
the 2nd one
Step-by-step explanation:
Answer:
A. 0
Step-by-step explanation:
3ab+5b-6
= 3(-1)(3)+5(3)-6
=3(-3)+15-6
=-9+9
=0 ( you have to subtract because they don't have the same signs)
Answer:
No
Step-by-step explanation:
First solve both equations:
1) 9x = 5x + 4
Simplifying
9x = 5x + 4
Reorder the terms:
9x = 4 + 5x
Solving
9x = 4 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
9x + -5x = 4 + 5x + -5x
Combine like terms: 9x + -5x = 4x
4x = 4 + 5x + -5x
Combine like terms: 5x + -5x = 0
4x = 4 + 0
4x = 4
Divide each side by '4'.
x = 1
Simplifying
x = 1
2) 14x = 4
14x = 4 (divide both sides by 14 to get x)
14x/14 = 4/14
x = 0.285714285714
As you can see, the value of x in the second equations is less than one, therefore making these algebraic equations not equivalent.
Answer:
There are 6 boxes
Step-by-step explanation:
We know there are 45 frames and 3 broken ones, so there are 48 frames in total.
We know there are 8 boxes that have the frames.
let x equal the amount of picture frames in a box
8x=48
8x/8 = 48/8
x=6
Answer:
$70,201.38
Step-by-step explanation:
To determine the principal amount, we can use the formula:

A = $200,000
r = 7% or 0.07
t = 15 years
n = 12
Now let's substitute our values.



So the principal needed to get 200,000 in 15 years is $70,201.38.
