Answer:

I am pretty sure the answer is 19/30

Step-by-step explanation:

If u turn 2 1/9 ÷ 3 1/3 into improper fractions u will get 19/9 Divided by 10/3

Then u do the butterfly. So this would be 9 x 10 =90 and 19 x 3 =57 so this is what it looks like 57/90 and that can be simpflyed into 19/30. Becasue 3 x 19 = 57 and 3 x 30 = 90

Find the indicated products.<br> (3x-5)(3x+5)

frutty [35]

9x²- 25

3x(3x) = 9x²
3x(5) = 15x
-5(3x) = -15x
-5(5) = -25
9x² + 15x - 15x - 25
9x² - 25 is your answer

The measures of the angles of ABC are given by the expressions in the table A( 6X - 1 ) ° B 20° C ( x + 14 ) ° what are the meas

lawyer [7]

Answer:

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees. This means that in triangle ABC,

Angle A + angle B + angle C = 180

Therefore,

6x - 1 + 20 + x + 14 = 180

6x + x + 20 + 14 - 1 = 180

7x + 33 = 180

Subtracting 33 from the left hand side and the right hand side of the equation, it becomes

7x + 33 - 33 = 180 - 33

7x = 147

Dividing the left hand side and the right hand side of the equation by 7, it becomes

7x/7 = 147/7

x = 21

Therefore

Angle A = 6x - 1 = 6 × 21 - 1

Angle A = 125 degrees

Angle C = x + 14 = 21 + 14

Angle C = 35 degrees.

C=.41+.26(z-1) solve for z

Ksivusya [100]

$c=0.41+0.26(z-1) \\0.26(z-1)=c-0.41 \\z-1=(c-0.41)/0.26 \\\boxed{z=(c-0.41)/0.26+1}$

Hope this helps.
