Solve the equation 7 − 2x = 19.

Karolina [17]

Answer:

-6

Step-by-step explanation:

firstly arrange whole equation,

-2x+7=19

Now, Transpose 7 to RHS (right hand side)

-2x=19-7

-2x=12

Further, seperate coefficient -2 from x

and transpose it to RHS and divide them

x=12/-2

Hence, x= -6

What is the solution of the equation shown?<br> -1.2(3x - 3) = 4(3x + 0.9)

MariettaO [177]

Answer: x=0

Step-by-step explanation: -1.2(3x-3) = 4(3x+0.9) -3.6x+3.6=12x+3.6 -3.6x-12x+12x=12x+3.x+12x -15.6x+3.6-3.6=3.6-3.6 -15.6x/-15.6=0/-15.6 x=0

Solve the right triangle, ΔABC, for all the missing side and angles to the nearest tenth given sides a = 10.6 and b = 19.2.

Aliun [14]

Answer:

Part 1) $c=21.9\ units$

Part 2) $B=61.1\°$

Part 3) $A=28.9\°$

Part 4) $C=90\°$

Step-by-step explanation:

step 1

Find the length side c

Applying the Pythagoras Theorem

$c^{2}=a^{2}+b^{2}$

substitute the given values

$c^{2}=10.6^{2}+19.2^{2}$

$c^{2}=481$

$c=21.9\ units$

step 2

Fin the measure of angle B

we know that

In the right triangle

$tan(B)=b/a$

substitute the given values

$tan(B)=19.2/10.6$

$B=arctan(19.2/10.6)=61.1\°$

step 3

Find the measure of angle A

we know that

The measure of interior angles in a triangle must be equal to 180 degrees

∠A+∠B+∠C=180°

Remember that in a right triangle the measure of angle C is 90 degrees

we have

$B=61.1\°$

$C=90\°$

substitute

$A+61.1\°+90\°=180\°$

$A=28.9\°$
