1 answer:
vazorg [7]4 years ago
6 0

Answer:

(3,6)

Step-by-step explanation:

2x-3y = -12

x+y=9. Solve for either y or x

-x. -x

y = -x + 9. Substitute this for the y

2x-3(-x+9)= -12

2x +3x-27 = -12. Add like terms

5x -27 = -12

+27. +27. Inverse operations

5x = 15

÷5. ÷5

x = 3

x + y = 9

3 + y = 9. Substitute 3 for x

-3. -3. Inverse operations

y = 6

Use the distributive property with factoring to find the equivalent expression. 24n + 32w = (3n + w)
pashok25 [27]

Answer:

Step-by-step explanation:

24n + 32w = (3n + w)

We're asked to use distributive property, this means that we have to find a way that the given expression on the left hand side is equal to the given incomplete exresssion on the right hand side. In so doing, we're fulfilling the distributive property tag.

Given 3n, 3 factorises 24 into 8, and at the same time, factorises 32 into 4. Thus, we can then conclude that

24n + 32w = 8(3n + 4w)

The question is below thanks
iren [92.7K]

Answer:

10.02 units

Step-by-step explanation:

FH = \frac{82}{360} \times 2 \pi r (Multiplying the circumference of the circle by the arc's degree over the total degree of the circle will find the length of the arc FH)

FH = \frac{82}{360}\times 2 \pi (7)

=\frac{82}{360}\times14\pi

=\frac{287\pi}{90}

=10.02 (to the nearest hundredth)

∴ The length of the arc FH is 10.02 units to the nearest hundredth.

Hope this helps :)
