Cosine of an angle is the adjacent leg divided by the hypotenuse.

So cos(60) = a / 12

I'm going to assume it's your last option because it's not in the picture.

Yes SOH-CAH-TOA, Cos= Hypotenuse+Adjacent, so, cos(60) a/12 would be the correct answer so D.

What expression is equivalent to -3+2/3y-4-1/3y

Neko [114]

Answer:

The simplified form of the given expression is $-7 + (\frac{1}{3})y$

Step-by-step explanation:

Here, the given expression is:

$-3 + (\frac{2}{3}) y - 4 - (\frac{1}{3})y$

Now to simplify the given expression, perform operations on LIKE TERMS:

We get:

$-3 + (\frac{2}{3}) y - 4 - (\frac{1}{3})y =( -3 - 4) + [(\frac{2}{3}) y- (\frac{1}{3})y]\\= - 7 + [(\frac{2}{3}) -(\frac{1}{3})]y = -7 + [\frac{2-1}{3}]y\\ = -7 + (\frac{1}{3})y\\ \implies -3 + (\frac{2}{3}) y - 4 - (\frac{1}{3})y = -7 + (\frac{1}{3})y$

Hence the simplified form of the given expression is $-7 + (\frac{1}{3})y$

Can someone help me with this problem 3(x+1)=11 I need it step by step

Nataly [62]

Answer:

x = 2.66666667

Step-by-step explanation:

3(x + 1) = 11

We multiply both x and 1 by 3 and get

3x + 3 = 11

Now we subtract 3 from both sides

3x + 3 - 3 = 11 - 3

3x = 8

Now divide both sides by 3

3x/3 = 8/3

x = 2.66666667
