Ksivusya [100]
When divided fractions you flip the second fraction

1/5 x 12/1

This then equals

Twice a number is 60 more than five times the number. what is the number?
Delvig [45]
Let the number be represented by x
2x=60+ 5x                          -20*2=60+5*-20
2x-5x=5x-5x+60                     -40=60+-100
-3x=60                                      -40=-40
-3x/-3=60/-3
x=-20
Therefore the number is -20

Your teacher tells you that a line goes through the points (-6, 1/2) and (-4, 3.)
rosijanka [135]

Answer:

Step-by-step explanation:

I'm pretty sure that the equation for slope is y2 -y1

                                                                        -----------

                                                                          x2 - x1

Substitute in the info, and simplify to find the slope.

Find x y and z. Thanks!
stepan [7]

Answer:

x = 6, z = 5.66 to nearest hundredth.

y = 90 degrees.

Step-by-step explanation:

From the chord intersection theorem 12*4 = 8 * x

So x = 6.

By the tangent / chord theorem:

z^2 = 2 * (12+4)

z^2 = 32

z = 5.66.

I'm not 100% sure of the value of angle y but I think its

1/2(100 + 80) = 90 degrees.

I'll try and check that out.

Yes that is right.

15 POINTS! Please answer question 17 (C) thank you!
asambeis [7]

Step-by-step explanation:

y=-1/2.x+2 =-2 then x=8

the area is S = \int\limits_{-3}^{8} |-1/2.x +2 - (-2)|dx =\int\limits_{-3}^{8} |-1/2.x +4|dx

S=121/4
