Answer: -16
Step-by-step explanation:
4m-15m-50=126
-11m=126+50
-11m=176
m=176/-11
m=-16
No se porque no se me van a hacer nada de eso
Answer:
Total Weight of Bowl W = 340 + (12.5T) grams
Step-by-step explanation:
Given
Weight of Ceramic Bowl = 340 grams
1 table Spoon of Sugar Weighs = 12.5 grams
So T table Spoon of Sugar Weighs = 12.5T
Total Weight of Bowl W = Weight of Ceramic Bowl + Weighs of T table Spoon of Sugar Weighs
Total Weight of Bowl W = 340+ (12.5T)grams
Simplify (x3 + 3x2 + 5x – 4) – (3x3 – 8x2 – 5x + 6)
The first thing I have to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a "1" in front of the parentheses, to help them keep track of the minus sign.
Here's what the subtraction looks like, when working horizontally:
(x3 + 3x2 + 5x – 4) – (3x3 – 8x2 – 5x + 6)
(x3 + 3x2 + 5x – 4) – 1(3x3 – 8x2 – 5x + 6)
(x3 + 3x2 + 5x – 4) – 1(3x3) – 1 (–8x2) – 1(–5x) – 1(6)
x3 + 3x2 + 5x – 4 – 3x3 + 8x2 + 5x – 6
x3 – 3x3 + 3x2 + 8x2 + 5x + 5x – 4 – 6
–2x3 + 11x2 + 10x –10
And here's what the subtraction looks like, when going vertically:

−(3x

+3x

−8x

+5x
−5x
−4
+6)
In the horizontal addition (above), you may have noticed that running the negative through the parentheses changed the sign on each and every term inside those parentheses. The shortcut when working vertically is to not bother writing in the subtaction sign or the parentheses; instead, write the second polynomial in the second row, and then just flip all the signs in that row, "plus" to "minus" and "minus" to "plus".

Answer:
20*(4/5)
Step-by-step explanation:
The expression you will use is :
20*(4/5) = 80/5 = 16
16 is 80 percent of 20 wich equals 4 fifths that's true
