(6,15)
Answer:
(-5, -2)
Because we weren't solving for x,y it's hard to say the order in which these should go so if it says that you're wrong again try switching them
Step-by-step explanation:
Looking at the first equation we know what p is equal to in terms of q so we can plug that value in for p in the second equation
2(q+3)+5q= -29
solve for q and get
2q+6+5q= -29
7q+6= -29
7q= -35
q= -5
Now that we know what q is equal to we can plug that value into the first equation and solve for p
p= -5+3
p= -2

Which tree grew at a slower rate for the first year?
Two trees were planted at the same time. Tree A grew 4.15 inches per month for the first year. Tree B grew 4.2 inches per month for the first year.
Answer:
Tree A
Step-by-step explanation:
Let me put this question a different way. Which tree will be the tallest at the end of the year?
Well, let's think about it. 12 months later, Tree A will have grown 4.15x12=49.8 inches. Tree B will have grown 4.2x12=50.4 inches. As 50.4 is greater than 49.8, we can see it is Tree B that was the tallest at the end of the year. So we can conclude that Tree B grows faster. This would mean that Tree A grew at a slower rate for the first year.
