Answer:

the answer is 2

Step-by-step explanation:

x divided by 2 + 7 = 11 is the question so you subtract 7 from 11 and get 4 so then you do 4 times 2 which equals 8 which is your answer

Set of the equation with x as the number, so you'd have 2*x+7 = 11. subtract both sides by 2*x = 4. divide both sides by 2 to get x = 2. the number is 2.

The current value of an investment is 125 percent of its initial value.The increase in value is $10million.What was the initial

kicyunya [14]

Answer:

$40 million

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Current value = 125%

which means that current value is 25% more than its initial value.

Let Initial Value = X

So, Increase in investment value = 25% × X = 0.25X

Given, increase value = $10million

So, 0.25X = $10 million

= X = $10million

= X = $10million ÷ 0.25

= X = $40 million

Hence the initial value of investment is $40million.

Please help me :)) algebra 2! what are the real roots?

irina1246 [14]

Answer:

Step-by-step explanation:

So we have the equation:

$3(x-4)^\frac{4}{3}+16=64$

First, let's subtract 16 from both sides:

$3(x-4)^\frac{4}{3}=48$

Now, let's divide both sides by 3:

$(x-4)^\frac{4}{3}=16$

Remember that with fractional exponents, we can move the denominator into the root position. Therefore:

$(\sqrt[3]{x-4})^4=16$

Let's take the fourth root of both sides. Since we're taking an even root, make sure to have the plus-minus symbol!

$\sqrt[3]{x-4} =\pm 2$

Cube both sides. Since we're cubing, the plus-minus stays.

$x-4=\pm 8$

Add 4 to both sides.

$x=\pm 8+4$

Calculator:

$x=8+4\text{ or } x=-8+4\\x=12\text{ or } x=-4$

So, our answer is A.

And we're done!
