Answer:
52
Step-by-step explanation:

(I replaced
with
since we are to find
.)
(By the order of operations, we take care of the exponents before whatever else we have here.)
(By the order of operations, we take care of the multiplication as we see if left to right.)
(By the order of operations, we perform addition/subtraction as we see it left to right.)
(This completes the simplification.)
We could have also put this in our calculator as:
4(4)^2 - 2(4) - 4
This would have returned 52.
Answer:
y=-1/3x-3
Step-by-step explanation:
(10x - 65) degrees is equal to (9x - 49) degrees, therefore you can set them into an equation.
(10x - 65) = (9x - 49)
By subtracting 9x in both sides,
(10x - 9x) - 65 = (9x -9x) - 49
x - 65 = -49
By adding 65 in both sides,
x - 65 + 65= -49 + 65
x = 16
Next, to find the value of z, it’s important to know that the straight line has 180 degrees. Then you would substitute the x value you found into one of your equation and subtract it from 180.
10 (16) - 65 = 160 - 65 = 95
Now you know that (10x - 65) degrees is equal to 95 degrees,
180 - 95 = z = 85
Answer: x = 16
z = 85

Step-by-step explanation:
To find the difference of this problem, start by simplifying the denominator, which will look like
. Next, multiply
by
to create a fraction with a common denominator in order to subtract from
. The problem will now look like
.
Then, simplify the terms in the problem by first multiplying
and
, which will look like
. The next step is to combine the numerators over the common denominator, which will look like
.
Next, simplify the numerator, and to simplify the numerator start by factoring 3 out of
, which will look like
. Then, subtract 14 from -7, which will look like
. The final answer will be
.
Answer:
3x + y - 3
Step-by-step explanation:
<u>Like Terms</u>: In algebra, like terms are terms that have the same variables and powers.
To simplify this expression and get an expression that is eual to 5x + 3y - 2x - 2y - 3 I used <em>like terms</em> :
(5x - 2x) + (3y - 2y)
(5x - 2x = <em>3x</em>) + (3y - 2y = <em>1y or y</em>)
3x + y
Then we add the <em>- 3 </em>at the end giving us:
<u><em>3x + y - 3</em></u>
