12(x-20)=-48 what is x

Mathematics
1 answer:
Sophie [7]2 years ago
3 0

Answer:

x = 16

Step-by-step explanation:

12(x - 20) = -48

Use distributive property

12*x - 12*20 = -48

12x - 240 = -48

Add 240 to both sides

12x = -48 + 240

12x = 192

Divide both sides by 12

x = 192/12

x = 16

If m<1 is the supplement of m<2 and the measure of each angle is given:
svp [43]

Answer:

m<1 = 121°

m<2 = 59°

Step-by-step explanation:

If m<1 is the supplement of m<2 and the measure of each angle is given:

m<1=2x+65

m<2=3x-25

Find m<1:

When two angles are supplement of each other, there sum is equal to 180°

i.e m<1 + m<2 = 180°

Putting values and finding angle 1

2x+65+3x-25=180\\5x+40=180\\5x=180-40\\5x=140\\x=\frac{140}{5}\\x=28

So, we get x=28

Now finding m<1 by putting x=28

m

Now, finding m<2 by putting x=28

m

So, we get:

m<1 = 121°

m<2 = 59°

Which equation results from isolating a radical term and squaring both sides of the equation for the equation ?
Bezzdna [24]
We can solve for the equivalent expression of the given expression:
√(x+6) + √x = 8
First, we need to square both sides such as shown below:
((√x+6) + (√x) =8)²
(x+6) + x = 64
Perform transposition and combine similar terms
x + 6 + x =64
2x = 64 -6
x = 29
