Answer:
60x + 18
Step-by-step explanation:
8x - 4 [2x - 5 ( 3x + 1 )] - 2 [x - (x - 1)]
distribute
8x - 4 [2x - 15x - 5] - 2 [x - x + 1]
combine like-terms
8x - 4 [- 13x - 5] - 2 [1]
distribute again
8x + 52x + 20 - 2
combine like-terms again
60x +18
Answer:
63.1°
Step-by-step explanation:
Complementary angles sum 90°
90 - 26.9 = 63.1°
Step-by-step explanation:
−2x+5y=−15 and 5x+2y=−6
Rewrite equations:
−2x+5y=−15;5x+2y=−6
Step: Solve−2x+5y=−15for x:
−2x+5y=−15
−2x+5y+−5y=−15+−5y(Add -5y to both sides)
−2x=−5y−15
−2x−2=−5y−15−2(Divide both sides by -2)
x=52y+152
Step: Substitute52y+152forxin5x+2y=−6:
5x+2y=−6
5(52y+152)+2y=−6
292y+752=−6(Simplify both sides of the equation)
292y+752+−752=−6+−752(Add (-75)/2 to both sides)
292y=−872
292y292=−872292(Divide both sides by 29/2)
y=−3
Step: Substitute−3foryinx=52y+152:
x=52y+152
x=52(−3)+152
x=0(Simplify both sides of the equation)
Answer:
x=0 and y=−3
<h2>
Answer:</h2><h2>The expressions that can be subtracted from 9x to result in the expression 3x+5 is 6x - 5</h2>
Step-by-step explanation:
To find the expression that can be subtracted from 9x to result in the expression 3x+5.
Let us consider the expression, a - b = c
Here a = 9x
the result, c = 3x + 5
b = ?
Substitute the values in the above equation, we get
9x - b = 3x + 5
9x - (3x + 5) = b
b = 6x - 5
The simplified form of the expression 6! − 3! when it is simplify using the properties of factorial is 3!((6x5x4) − 1).

What is the simplified form of a term?</h3>
Simplified form of a term is the simplest way of expression the term, which is obtained by applying the required operations of mathematics.
Factorial is the way to write the product of the numbers from its phase value to 1 in decreasing order. Suppose, the number is 3!. Then it can be written as,
3!=3×2×1
The expression which has to be simplified is,
6! - 3!
It can be written as,
6! - 3!
(6×5×4×3!)-3!
3!((6×5×4)-1)
Thus, the simplified form of the expression 6! − 3! when it is simplify using the properties of factorial is 3!((6x5x4) − 1).
