Well first off a term is each of the quantities in a ratio, series or mathematical equation, so every # is a term. And secondly when simplifying you combine the terms that have the same degree, so 3+5 get combines but 7y-3 dont.
a. 3y+2y+y^2+5+y there are 5 terms and the simplified answer is 6y+y^2+5
b. 3y^2+2xy+1+3x+y+2x^2 there are 6 terms and it is already simplified
c. 3xy+5x+2+3y+x+4 there are 6 terms and the simplified answer is 3xy+6x+6+3y
d. 4m+2mn+m^2+m+3m^2 there are 5 terms and the simplifies answer is 5m+2mn+4m^2
Answer: the answer is 7
Step-by-step explanation: add 9 to both sides, eliminating -9 so now you have 7x=49 divide both by 7 and you get x= 7 check it by inputing 7 for x, 7(7)-9=40
7(7)=49 next 49-9= 40
it checks out, so x= 7
Answer:
36girls
Step-by-step explanation:
3/1*12=36. To check 36/12=3/1=3:1
Let the length be x and the width be y, then
2x + 2y = 56
x + y = 28 . . . (1)
x = 4 + 3y . . . (2)
Putting (2) into (1) gives
4 + 3y + y = 28
4y = 28 - 4 = 24
y = 24/4 = 6
x = 4 + 3(6) = 4 + 18 = 22
Therefore, length is 22 inches and width is 6 inches.
You ca go to tiger math and put in any equation and it will give you the answer to any of them.
