I'm going to take a guess at this and say what you meant is 2401 = 7^(6 - 2x)
Step One
Find out the power of 7 that will equal 2401.
You could do it like this.
7^y = 2401 and just guess at some values.
y 7^y
1 7
2 49
3 7 * 7 * 7 = 343
4 7 * 7 * 7 * 7 = 2401 So the answer is 4
7^4 = 2401
Step 2
Equate the powers.
2401 = 7^(6 - 2x)
7^4 = 7^ (6 - 2x)
4 = 6 - 2x Subtract 6 from both sides.
4 - 6 = - 2x
-2 = - 2x divide by - 2
-2/-2 = x
x = 1 <<<<<<<<<<<<<answer
Answer:
A
Step-by-step explanation: You are correct!
122.5.
A=b x h/2. A=122.5 b=7
A x b=h
122.5 x 7 =122.5
Step-by-step explanation:
Let original price be x
Price after 40% discount is $201
Therefore
x × 40% = $201
x = 201 ÷ (40/100)
x = 502.5
Therefore, the original price is $502.5
Hope it helps :)
