7 = 3/9x solve for x
noname [10]

Answer:

x = 1/21

Step-by-step explanation:

7 = 3/9x

Multiply both sides by 9x

7 x 9x = 3/9x x 9x

9x cancels out on the right side

63x = 3

Divide both sides by 63 to isolate x

63x/63 = 3/63

x = 1/21

Suppose the diameter of a circle is 16. what is its circumference?
dolphi86 [110]
The circumference of the circle formula is 2πr or πd.

We will use πd since we know the diameter.

C = πd
C = (3.14)(16)
C = 50.24

Hope this helps :)

For questions 1 - 2, use the distributive property to find the product of the binomials.
igor_vitrenko [27]

Answer:

1).  2x^2-3x+20

2). 4x^2-14x+6

Step-by-step explanation:

1. (x-4)(2x+5)

FOIL:

(x)(2x)+5(x)-8(x)+(4)(5)

2x^2+5x-8x+20

=2x^2-3x+20

2. (4x-2)(x-3)

FOIL:

(4x)(x)-(3)(4x)-2(x)-2(-3)

4x^2-12x-2x+6

=4x^2-14x+6

Can someone help me with this please!~
Eduardwww [97]
Note that sum of triangle interior angles is 180. So,

(12x+12)+15+(3x+18)=180

15x+45=180

15x=135

x=9

Since A=12x+12=12.9+12=120

And C=3x+18=3.9+18=45
