Answer:

64 left handed girls

25 left handed boys

89 total left handed students

Step-by-step explanation:

Multiply 320 x 0.2

Multiply 250 x 0.1

You can think of it this way, 0.2 is 2/10 and 0.1 is 1/10 so take 20 percent of 320 and 10 percent of 250

Add them up for your answer 64 + 25 = 89

What is x equal to????

Ksju [112]

Answer:

x = 20

Step-by-step explanation:

The 3 arcs UV, VW, WX form a semicircle, so sum to 180° , that is

4x + 2 + x + 78 = 180

5x + 80 = 180 ( subtract 80 from both sides )

5x = 100 ( divide both sides by 5 )

x = 20

The equation of the line with slope -3 that goes through the point (-9,-7) can be written in the form y=mx+b

katrin2010 [14]

Answer:y= -9x-25

Step-by-step explanation: Write the slope-intercept form of an equation of the line with slope -9 and passes through the point (-2, -7).

--------

Form:: y = mx + b

Solve for "b"::

-7 = -9*-2 + b

-7 = 18 + b

b = -25

-----

Equation:

y = -9x - 25

---------------

Cheers,

Stan H.

-----------

point slope formula

y-y1=m(x-x1)

y+7= -9(x+2). Notice that we are subtracting a negative, so we have to add.

y+7=-9x-18

y= -9x-25

kati45 [8]

Answer:

y = 19 (3)x

Explanation:

y = abx

Plug in the numbers from the 2 given points to find a and b.

19 = ab0 = a
a = 19

171 = 19b2
b = 3

y = 19 (3)x

3. Simplify the following inequalities.

saw5 [17]

Answer:

7x+7 > 23-x

group like terms

7x+ x > 23-7

8x > 16

we divide both side by

8x > 16

8 8

so 8 cancelled out 8 living

x > 16

8

x > 2
