Answer:
10x-3y=12
Step-by-step explanation:
In algebra, we always add alike terms. Meaning, when a set has numbers with the same variable, in this case it was x, we can add/substract/divide them to simplify the equations.
D e c a is all the answer
Answer:
1 cm
Step-by-step explanation:
We know that the formula for perimeter is<u> 2(l+w) or l+l+w+w</u>
We know that the height is 5 cm so that means <em><u>w= 5</u></em> also that there is 5 cm on both sides of the rectangle. So 5+5=10 so that means that the length of the rectangle is <em><u>1 cm</u></em> if you add the length together you 2 when you add the width you get 10. <em>10+2=12.</em>
3/5g-(1/3)=(-10/3)
move the 1/3 over
3/5g=(-10/3)+(1/3) (notice the + sign)
3/5g= (-9/3)
3/5g=(-3)
move the 3/5 over (divide)
g= (-3/(3/5))
g= (-3x5/3)
g= -15/3
g= -5
Answer:
200 messages
Step-by-step explanation:
Let m = number of messages.
Plan A: 0.1m + 40
Plan B: 60
0.1m + 40 = 60
0.1m = 20
m = 20/0.1
m = 200
