Solve the equation: Show work step by step<br><br> -14=-5+3c
arsen [322]
-14 = -5 + 3c

First, regroup your terms. / Your problem should look like: -14 = 3c - 5
Second, add 5 to both sides. / Your problem should look like: -14 + 5 = 3c
Third, simplify -14 + 5 to -9. / Your problem should look like: -9 = 3c
Fourth, divide both sides by 3. / Your problem should look like: -\frac{9}{3} = c
Fifth, simplify the fraction to 3. / Your problem should look like: -3 = c
Sixth, switch your sides. / Your problem should look like: c = -3

Answer: c = -3

Please help me guys ​

Step-by-step explanation:

midpoint : it is the point in the middle marking half of the total distance.

therefore,

1)

EV = LE = LV/2

10 = 5m

m = 2

2)

LR = RO = LO/2

n + 4 = 12

n = 8

3)

LER and LVO are similar triangles. that means they have the same angles, and the ratio of one corresponding pair of lines or sides between both triangles is the same for all corresponding line pairs.

we know e.g. LE/LV = 1/2.

the same ratio applies then to ER/VO = 1/2 = 18/20p.

18/20p = 1/2

18 = 20p/2

2×18 = 20p

36 = 20p

p = 36/20 = 9/5 = 1.88888888888...

4)

VL = 2×EL = 2×10 = 20

5)

LO = 2×RO = 2×12 = 24

6)

as we have already calculated for 3) :

VO = 36

7)

36 + 20 + 24 = 80

8)

10 + 12 + 18 = 40

9)

remember, the and angles in similar triangles.

LVO = 52°

10)

all angles around a single point in one side of a line are together 180°.

in this case there are 2 angles around E : LER and VER.

VER = 180 - LER = 180 - 52 = 128°

Answer:

A)  

3x + 24 + 10 = 5x - 10 - x + 2

34 = 2x -8 - x

34 = x - 8

42 = x

or

<u><em>x = 42 million</em></u>


B)

<u><em>CORRECT! (1.2 million)</em></u>


C)

<u><em>0.028 = 3% if rounded.</em></u>

<u><em>The death rate is 3% </em></u>
