How do you solve and check x/4 = -5

Mathematics
1 answer:
Mashutka [201]3 years ago
6 0

Rearrange x/4-(-5)=0

Simplify x/4

-5 = -5/1 = -5*4/4

x- (-5*4)/4 = x+20/4

x+ 20/4 = 0

x+20/4 * 4 = 0*4

The equation now takes the shape: x+20=0

subtract 20 from both sides of the equation: x=-20

Answer: x=-20

Sonbull [250]

Answer:

V =  \frac{4}{3} \pi {r}^{3}  \\  \\ 3V = 4\pi {r}^{3}  \\  {r}^{3}  =  \frac{3V}{4\pi}  \\  \\ r =  \sqrt[3]{ \frac{3V}{4\pi} }

Seascapes rent small fishing boats for a day-long fishing trips. each boat can carry only 1200 lb of people and gear for safety
solmaris [256]

A. We are given that each person weighs 150 lb, each gear per person weighs 10 lb, and a total of 200 pounds of gear for the boat itself.

Since each person only carries one gear, therefore total weight per person in 160 lb (weight of person + weight of gear).

So let us say that x is the number of persons, the inequality equation is:

 

160 x + 200 ≤ 1200

 

 

B. There are three groups that wish to rent the boat.

> Solve the inequality equation when x = 4

160 (4) + 200 ≤ 1200

840 ≤ 1200           (TRUE)

 

> Solve the inequality equation when x = 5

160 (5) + 200 ≤ 1200

1000 ≤ 1200         (TRUE)

 

> Solve the inequality equation when x = 8

160 (8) + 200 ≤ 1200

1480 ≤ 1200         (FALSE)

 

So only the 4 people group and 5 people group can safely run the boat.

 

 

C. Find the maximum number of people that may safely use the boat, solve for x:

 

160 x + 200 ≤ 1200

160 x ≤ 1000

x ≤ 6.25

 

Therefore the maximum number of people that can safely use the boat is 6 people.

PLEASE HELP PLA
aleksley [76]

Answer:

y = -x+8

Step-by-step explanation:

The side that is parallel to BC is EF

Find the slope of EF:

m = \frac{2-4}{6-4} =\frac{-2}{-2} =-1

Easiest way is just put the formula in point-slope form and simplify.

Let's use point F, which is (6,2)

y -2=-(x-6)

Simplify:

y-2=-x+6

Add 2 on both sides:

y = -x+8

Hope this helped
