Answer:
Step-by-step explanation:
The question is slightly ambiguous. The problem is, do you find the first 40 hours using 10x and then the second equation using x >40. I don't think so, but it should be made clear. It turns out that the first 40 hours does equal 400 so that you can use the second expression with no worries.
w(53) = 15(53 - 40) + 400
w(53) = 15(13) + 400
w(53) = 195 + 400
w(53) = 595
Answer:
Sure thing!
For the first equation 6v+38≤ -4
The answer would be v≤-7
and for the second equation 2(v+3)≥-2
the answer would be v≥-4
Step-by-step explanation:
6v+38≤ -4
Subtract 38 from both sides
6v+38-38≤-4-38
Simplify
6v≤-42
Divide both sides by 6
6v/6≤-42/6
Simplify
v≤-7
SAME THING FOR THE OTHER
2(v+3)≥-2
Divide both sides by 2
2(v+3)/2≥-2/2
Simplify
v+3≥-1
Subtract 3 from both sides
v+3-3≥-1-3
And finally, simplify
v≥-4

Answer:
20 rabbits, 10 chickens
Step-by-step explanation:
Because chickens and rabbits each have 2 eyes, the number of animals is 60 ÷ 2 = 30.
Let's say that all of the 30 animals are chickens. There would be a total of 30 × 2 = 60 legs.
So the extra (100 – 60) = 40 legs must have come from the rabbits.
Every rabbit has (4 – 2) = 2 more legs than a chicken.
So there are 40 ÷ 2 = 20 rabbits and 30 – 20 = 10 chickens.
Answer:
C
Step-by-step explanation:
4x-10+2x+15+x=180
7x+5=180
7x=175
x=25
So 2x+15=65 and 4x-10=90.
90+65+25=180
So your triangle is a right triangle.
