The answer=24 that he needs to put in each pile
Answer:
<em><u>z = -3</u></em>
Step-by-step explanation:
<u>Step 1: Simplify both sides of the equation.
</u>
z+7=−z+1
<u>Step 2: Add z to both sides.
</u>
z+7+z=−z+1+z
2z+7=1
<u>Step 3: Subtract 7 from both sides.
</u>
2z+7−7=1−7
2z=−6
<u>Step 4: Divide both sides by 2.
</u>
<u>2z</u> = <u>−6
</u>
2 2
z=−3
Answer:
true
Step-by-step explanation:
3(1)+3(-2)
3+(-6)=-3
-3<33 is true
Find the gradient so (-5-3)/(2+1) =-8/3 input it in y=mx+c and also use the coordinates from the question
So it becomes
3=-8/3 (-1) + c
C=1/3
Y=-8/3 x+1/3
Answer:
Step-by-step explanation:
Let the number of visits to a pool = n
Charges of n visits = Number of visits × Charges per visit
= n × $4
= 4n
Let the membership amount of the pool = $m
So the inequality showing that a membership is less expensive than paying each visit to the pool will be
4n > m
Now we divide the inequality by 4
n > 
Therefore, membership of the pool will be less expensive until number of visits to the pool is one fourth of the membership.
