Answer:
The answer is $420 dollars
Step-by-step explanation:
you times 560 by 25%
that comes to a total of 140/
Ms. Dawson's class raised 25 percent more so you would have to subtract 140 from 560
560-140=420
420 is how much Mr. Casey's class raised
Answer:
Y=3/4x+4
Step-by-step explanation:
Write in form the form of y=mx + c... Where your m slope is 3/4 and your c is your y intercept 4
Answer:
Step-by-step explanation:
S+J+M=36
J=S-2 or J=x-2
M=S-16 or M=x-16
Answer:
This is the shorthand way of writing
=====================================================
Work Shown:
The plus or minus is needed because squaring a negative leads to a positive. As another example, x^2 = 25 has x = 5 and x = -5 as the two solutions. Note that x^2 = (-5)^2 = (-5)*(-5) = 25.
Also, note that the 80 was broken up into 16*5. This was done to simplify the square root. We pull out the largest factor that's a perfect square.
So that's how we get to the solution set . The curly braces tell the reader that they are dealing with a set.
Combine 2a^3+5a-7 and 5a^2-6a+12.
Rewrite this so that the second expression is beneath the first:
2a^3+5a-7
5a^2-6a+12
Combine like terms. The highest order term is 2a^3:
2a^3+0a^2 +5a-7
+5a^2 - 6a+12
----------------------------
2a^3 + 5a^2 - a + 5 (answer)
Note how these terms are in descending order by power of a.
