Answer:

175

Step-by-step explanation:

5/24 = 0.208 percentage of defective bolts

scale up to 840 bolts by finding 20.8% of defective bolts

840*20.8 = 175

Which equation is a point-slope form of the equation of this line (-2, 1 ) and (1, 7 )

lana [24]

The point-slope formula:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have (-2, 1) and (1, 7).

Substitute:

$m=\dfrac{7-1}{1-(-2)}=\dfrac{6}{3}=2$

$y-1=2(x-(-2))\\\\y-1=2(x+2)$

A theater sells tickets for a concert . Tickets for lower level sells for $35 each , tickets for upper level sell for $25 each .

arlik [135]

150 lower level
200 upper level

Let x = lower level and y = upper level. You can then set up an equation for cost as:

35x + 25y = 10,250

and the equation for total tickets as:

x + y = 350.

Solve using any method.

Answer:

n ≤ 5

Step-by-step explanation:

First, we add 14 to both sides. This gets us 5n ≤ 25. Next, we divide both sides by 5. This gets us n ≤ 5. I hope this helps!
