We can do anything to an equation as long as we do it to both sides
remember the associative property of addition

a+(b+c)=(a+b)+c
so
12+(7+m)=(12+7)+m=19+m

19+m=30
minus 19 both sides
19-19+m=30-19
0+m=11
m=11

A box at a miniature golf course contains contains 4 red golf balls, 8 green golf balls, and 7 yellow golf balls. What is the pr
Solnce55 [7]

Answer:

 =57.89%

Step-by-step explanation:

The total number of golf ball is 4+8+7 = 19

P (red or yellow) = number of red or yellow

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

                                total number of golf balls

                           = 4+7

                              -----

                              19

                         =11/19

Changing this to a percent means changing it to a decimal and multiplying by 100%

                        = .578947368 * 100%

                         =57.8947368%

Rounding to two decimal places

                         =57.89%

A city of 6,688 has an area of 16 square miles. What is the population density of the city?
Ahat [919]
To find population density, it is population / area.

The population is 6688, divided by the area of 16.

6688/16 = 418

So the population density is 418 people per sq mile.

Find the equation (in terms of x ) of the line through the points (-2,5) and (3,4)<br> y=
Alja [10]

Answer:

y = (-1/5)x + 23/5

Step-by-step explanation:

Given:

Two points;

(-2,5) and (3,4)

Find:

Equation of slope

Computation:

y = mx + b

5 = m(-2) + b

5 = -2m + b .......... Eq1

4 = m(3) + b

4 = 3m + b .......... Eq2

Eq2 - Eq1

-1 = 5m

m = -1/5

5 = -2m + b

5 = -2(-1/5) + b

5 = 2/5 + b

b = 23/5

y = mx + b

y = (-1/5)x + 23/5
