Answer:
<u>x=90</u>
Step-by-step explanation:
<em />
<em>Let's solve your equation step-by-step.</em>
x/9−5=5
<em>Step 1: Simplify both sides of the equation.</em>
x/9−5=5
1/9x+−5=5
1/9x−5=5
<em>Step 2: Add 5 to both sides.</em>
1/9x−5+5=5+5
1/9x=10
<em>Step 3: Multiply both sides by 9.</em>
9*(1/9x)=(9)*(10)
x=90
Answer:
<u>x=90</u>
For this case we have the following expression:

Rewriting the expression we have:

Where,
x: exponent to which we must raise the expression to obtain 7 as a result.
We have then:

The exponent must be equal to 1:

Clearing x we have:

Substituting valres:
Answer:
you must raise the expression to 2
Answer:
14
Step-by-step explanation:
Hypotenuse^2=base^2+perp^2
50^2=base^2+48^2
2500-2304=base^2
Base^2=196
Taking sq root
Base=14
