For the first one we divide every element by sqrt3
we get
q+2/sqrt3 =sqrt5/sqrt3
q=(sqrt5-2)/sqrt3
q=sqrt3*sqrt5-2*sqrt3/3
q=sqrt15-2sqrt3/3
which is the third option
For the second one
sqrt(2y-5) +4=8
first we move the 4 to the right
sqrt(2y-5)=4
we remove the square root by bringing to the power of two
2y-5=16
2y=21
y=21/2
y=10 1/2
third option
60 more squirrels is the answer because sine its an estimate, 91 turns into 90
therefore u have
90 squirrels and 1/3 as many chipmunks
1/3 of 90 is 30
90 - 30 = 60
Your answer is 60 more squirrels
It was 18.6 years older than the average bird.
Answer:
x = -3, y = 24
Step-by-step explanation:
y=−7x+3;y=−8x
Step: Solve y=−7x+3 for y:
y=−7x+3
Step: Substitute−7x+3 for y in y=−8x:
y=−8x
−7x+3=−8x
−7x+3+8x=−8x+8x(Add 8x to both sides)
x+3=0
x+3+−3=0+−3(Add -3 to both sides)
x=−3
Step: Substitute−3 for x in y=−7x+3:
y=−7x+3
y=(−7)(−3)+3
y=24(Simplify both sides of the equation)
4 minutes 1000 meters
1000÷4=250 per minute
250÷60=4.166
so final answer rounded to the nearest tenth is 4.2!
