7Cos33. use Soh Cah Toa to remember Sine Cosine and Tangent. SINE opposite hypotnuse,, COSINE, Adjacent Hypotnuse,, TANGENT Opposite adjacent. so the problem starts as Cos33°= Adjacent/7 . but to type it in the calculator, it becomes 7Cos33° . (think of adjacent as “X” and that you need to get X alone,, so you multiply 7 on both sides to get X alone. We multiply bc multiplication undos division)

The simplified expression of $$4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$ is $4x^3$ .

Solution:

Given expression is $4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$ .

To simplify the given expression.

$$\Rightarrow4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$

Using exponent rule: $\frac{1}{a^{-m}}=a^m$

$$\Rightarrow4x \cdot x^{5}.x^{-3}$

Using another exponent rule: $a^m \cdot a^n=a^{m+n}$

$$\Rightarrow4x \cdot x^{5-3}$

$$\Rightarrow4x \cdot x^{2}$

Using exponent rule: $a^m \cdot a^n=a^{m+n}$

$$\Rightarrow4x^{1+2}$

$$\Rightarrow4x^3$

Hence the simplified expression of $$4 x \cdot \frac{1}{x^{-5}} \cdot x^{-3}$ is $4x^3$ .

Solve for X: 1/2(4+X)+2=16

Zanzabum

1/2(4+X)+2=16
2+(0.5 x X) + 2 = 16
4 + (0.5 x X) = 16
0.5 x X = 12
X = 24

idk if u understand my working out - message me if u dont
