HELP ME ASAP. The answer is -10 but explain it how to do it step by step. -6+(-30) divided by 5-(-2)

Alex777 [14]

Step-by-step explanation:

Following the order of operations we would first divide -30 by 5 which would give us -6

-6 + (-30) ÷ 5 - (-2)

From here we can add -6 + -6 = -12

-6 + (-6) - (-2)

When subtracting a negative number, the two negatives changes it to a positive. (-12) - (-2) = (-12) + 2 which would give us -10

(-12) - (-2) = -10

~Hope this helps!~

Suppose that 2000 is invented at a rate of 3.5%, compounded semiannually. Assuming that no withdrawals are made, find the total

Vinvika [58]

Answer:

$2,297.76

Step-by-step explanation:

Present value: P = 2000

Future value: F

Annual interest rate: r = 3.5% = 0.035

Time: t = 4 years

Number of compounding periods per year: n = 2

$F = P(1 + \dfrac{r}{n})^{nt}$

$F = 2000(1 + \dfrac{0.035}{2})^{2 \times 4}$

$F = 2000(1 + 0.0175)^{8}$

$F = 2000(1.0175)^{8}$

$F = 2000(1.148881783)$

$F = 2297.76$

Answer: $2,297.76

Solve for x in the equation 3 x squared minus 18 x + 5 = 47.

Lana71 [14]

Answer:

first option

Step-by-step explanation:

3x² - 18x + 5 = 47 ( subtract 5 from both sides )

3x² - 18x = 42 ( divide through by 3 )

x² - 6x = 14

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + 9 = 14 + 9

(x - 3)² = 23 ( take square root of both sides )

x - 3 = ± $\sqrt{23}$ ( add 3 to both sides )

x = 3 ± $\sqrt{23}$
