Answer:

HOPE THAT MAY HELP YOU :)

Step-by-step explanation:

Equal groups are illustrations of using the same variable.

A word problem that uses equal group is:

Christopher traveled a distance of 5 miles yesterday; he traveled a distance of 4 miles earlier today. Calculate the total distance traveled

The only condition for equal groups is that:

The units or variable must be the same

For instance:

Add 5 miles and 4 miles ----- This represents distance

Remove 2 liters from 7 liters --- This represents volume

Add 5 hours and quarter of an hour -- This represents time

And so on.

Answer:

23: y = -0.4

24: b = -1.8

25: m = 1/2

26: g = 1/4

27: s = 3/2

28: w = -12/5

29: z = 5/4

30: a = -9/5

Step-by-step explanation:

23:

$3y + 5.2 = -5y + 2$
$3y+5.2+5y=-5y+2+5y$
$8y + 5.2 = 2$
$8y+5.2-5.2=2-5.2$
$8y = -3.2$
$\frac{8y}{8} = \frac{-3.2}{8}$
$y = -0.4$

24:

$10b-2=7b-7.4$
$10b-2-7b=7b-7.4-7b$
$3b - 2 = -7.4$
$3b -2 + 2 = -7.4 + 2$
$3b = -5.4$
$\frac{3b}{3} = \frac{-5.4}{3}$

$b = -1.8$

25:

$2m - 2 = 6m - 4$
$2m-2-6m=6m-4-6m$
$-4m-2=-4$
$-4m-2+2=-4+2$
$-4m = -2$
$\frac{-4m}{-4} = \frac{-2}{-4}$
$m = \frac{1}{2}$

26:

$3g+5=7g+4$
$3g+5-7g=7g+4-7g$
$-4g+5=4$
$-4g + 5 - 5 = 4-5$
$-4g = -1$
$\frac{-4g}{-4} = \frac{-1}{-4}$
$g = \frac{1}{4}$

27:

$4s-1=-2s+8$
$4s-1+2s=-2s+8+2s$
$6s - 1 = 8$
$6s - 1 + 1 = 8+1$
$6s = 9$
$\frac{6s}{6} = \frac{9}{6}$
$s = \frac{3}{2}$

28:

$9w+3=4w-9$
$9w+3-4w=4w-9-4w$
$5w + 3=-9$
$5w + 3 - 3 = -9-3$
$5w = -12$
$\frac{5w}{5} = \frac{-12}{5}$
$w = \frac{-12}{5}$

29:

$6z-7=2z-2$
$6z-7-2z=2z-2-2z$
$4z -7 = -2$
$4z-7+7=-2+7$
$4z = 5$
$\frac{4z}{4} = \frac{5}{4}$
$z = \frac{5}{4}$

30:

$-a+3=4a+12$
$-a+3-4a=4a+12-4a$
$-5a+3=12$
$-5a + 3 - 3 = 12-3$
$-5a = 9$
$\frac{-5a}{-5} = \frac{9}{-5}$
$a = -\frac{9}{5}$

Need help asap please

zhenek [66]

Answer:

114°

Step-by-step explanation:

First we have to calculate the value of c Then

3c - 84° + c = 180° <being co-interior angles >

4c - 84° = 180°

4c = 180° + 84

4c = 264°

c = 264° / 4

c = 66°

Now

<R = 3 * 66° - 84°

= 114°

<P = <R ( being opposite angles of rhombus )

<P = 114°

Hope it will help :)

Answer:

(x, y) (1,5.5) , (2,5.75) (3,5.83) (4,5.875) (5,5.9)

Step-by-step explanation:

The x values lie on the horizontal line and the y values lie on the vertical line.

In order to find the value of y you must substitute the value of x in the equation given and you must plot you graph using the answers you got which I wrote for you.

NOTE:if there's anything you don't understand let me know.
