Answer: -b - 9

Step-by-step explanation:

First, since the a cancel eachother out we are left with (4-b) + (-6-7)

Second, you want to add the -6 and -7 to get -13, so (4-b) - 13

Finally, add the 4 to the negative 13 to get (-b - 9)

Hope this helps.

A particular rocket taking off from the earth surface uses fuel at a constant rate of 12.5 gallons per minute the rocket initial

faltersainse [42]

Answer:

$y=12.5x+225$

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the amount of fuel in gallons

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the unit rate or slope

b is the y-intercept or initial value

we have that

The unit rate or slope is equal to

$m=12.5\ \frac{gal}{min}$

$b=225\ gal$ ----> initial value (value of y when the value of x is equal to zero)

substitute

$y=12.5x+225$

The perimeter of a triangular sail is 44 feet. One side of the sail measures 18 feet and the second side measures 11 feet. What

Fantom [35]

Answer: The length of third side is 15.

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The perimeter of given triangle is 44.

One side, suppose a is 18.

Second side, suppose b is 11.

Suppose, third side is c.

So the perimeter will be :

$18+11+c=44$

$29+c=44$

Subtracting 29 in both sides

$29+c-29=44-29$

$c=15$

Hence the length of third side is 15. Answer

Hope it will help :)
