8% = 80/100 divide both by 4 =2/25
2/25*x=2
2x=25*2
2x=50
x=25
hope it helps

What is the simplified expression for 5 a b + 9 a b minus a b?

aalyn [17]

Answer:

13ab

Step-by-step explanation:

When you add the 5 and 9 it will give you 14 but you still have to subtract the 1ab(there is a 1 in front of variables that don't have a visible number.) So it will be 13 a b.

Find the x- and y-intercepts of the graph of the equation y = x2 – 2.

sertanlavr [38]

Answer:

See below ~

Step-by-step explanation:

<u>X-intercept(s) : Take y = 0</u>

0 = x² - 2
x = ±√2
X-intercepts are : (-√2, 0) and (√2, 0)

<u>Y-intercept : Take x = 0</u>

y = (0)² - 2
y = -2
Y-intercept is : (0, -2)

I need help trying to understand how they solved this equation. Just a little confused.

Misha Larkins [42]

Answer:

0.495

Explanation:

Given the expression:

$0.55-1.645\sqrt[]{\frac{0.55(1-0.55)}{220}}$

Begin by simplifying the expression under the radical (square root) sign.

$\begin{gathered} =0.55-1.645\sqrt[]{\frac{0.55(0.45)}{220}} \\ =0.55-1.645\sqrt[]{\frac{0.2475}{220}} \end{gathered}$

Using a calculator, we evaluate the radical:

$\begin{gathered} =0.55-1.645\sqrt[]{0.001125} \\ =0.494825 \\ \approx0.495\text{ (to 3 decimal places)} \end{gathered}$
