23800 is 34% of annual income. what is the income?
BARSIC [14]

Hey there!

If you ever see the word "is" in a story problem, it means that there is an equal sign there. Let's apply that to this.

23800 =(is) 0.34i (income)

Now, we can solve for i by dividing.

23800/0.34= 70,000

Therefore, the annual income is $70,000.

I hope this helps! Have a great day!

How do you solve 10≤2x≤x+9? The answer says it's 5≤x≤9 but i have no idea how it got there
Tanya [424]

Answer:

Step-by-step explanation:

so why this kind of problem is so confusing is b/c it's 2 problems in one

if you were to expand this it look like this

10 ≤2x

and

2x ≤x+9

This is really saying.. that x has a range.. and that the 1st equations is the lower stop point,  and that the 2nd equations is the upper stop point

once it's taken apart.. I bet you can solve it pretty quickly.

5≤x

and

x ≤9

then just put it back together in that confusing .. yet handy way to write it,

5≤x≤9

What is the exact value of the expression the square root 72. − the square root of 8. + the square root of 128.? Simplify if pos
ivann1987 [24]
Remember, the exact value cannot involve any rounding or estimates. Now, let's solve this problem. First, we have to translate it into an expression:

√72 - √8 + √128               separate the terms into square roots

√36·2 - √4·2 + √64·2        square root the terms that you can

6√2 - 2√2 + 8√2               they have like radical terms, so combine the terms

6 - 2 + 8 = 12                   the coefficients are 12 when combined

12√2                                 this is the EXACT VALUE of the expression

Hope this helps!
