1.write an algebraic expression to represent "five plus the quotient of r and 14" a. 5+14r b. 5+14/r c. 5+r/14 d. 5- r/14 2. write an equation to represent the statement "four less than the product of three and x is twenty- three" a. 3x-4=23 b. 4-3x=23 c.4x-3=23 d.3-4x=23

I agree with the other person, and heres the rest

1.=C

2=A

3.A

4.D

Step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
