Answer:

Step-by-step explanation:

Let's angle be x and y

Then......

⅓x+12=y......eqn(I)

Since are linear

x+y=180

y=180-x.....eqn(ii)

Substitute the eqns

You get x=126°

From eqn (iii)

You get y=54°

Those are angles

\text{Let the angles be (x) and (180-x)}\\\implies \frac{x}{3}+12=180-x\\\implies \frac{4x}{3}=180-12=168\\\implies x=42\times 3=126\\

Thus the two angles are $126°$ and $(180-126)°=54°$

Solve. 3(x-6)-2(2x+3)=14
coldgirl [10]

Answer:

x=-38

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(x−6)−2(2x+3)=14

(3)(x)+(3)(−6)+(−2)(2x)+(−2)(3)=14(Distribute)

3x+−18+−4x+−6=14

(3x+−4x)+(−18+−6)=14(Combine Like Terms)

−x+−24=14

−x−24=14

Step 2: Add 24 to both sides.

−x−24+24=14+24

−x=38

Step 3: Divide both sides by -1.

−x

−1

=

38

−1

x=−38

.Shaun estimated that the attendance at a college
Serggg [28]

Answer:

38.72%

Step-by-step explanation:

Estimated attendance = 1,000

The actual value of attendance = 1,632

We need to find the percent error of Shaun's estimate. Using the formula as follows :

\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100

Put all the values,

\%=\dfrac{1632-1000}{1632}\times 100\\\\=38.72\%

So, the percent error of Shaun's estimate is 38.72%.
