Answer:
this is a very complicated question
Answer:
Step-by-step explanation:
Divide by - 5
-5(2w + 1) / - 5 = 25 / - 5
2w + 1 = - 5
Subtract 1 from both sides.
2w + 1 - 1 = - 5 - 1
2w = - 6
Divide by 2
2w/2 = -6/2
w = - 3
-5(2w+1)=25
Multiply both sides by -5
(-5)(2w)=-10w
(-5)(1)=-5
-10w-5=25
Move -5 to the other side. Sign changes from -5 to +5.
-10w-5+5=25+5
-10w=30
Divide by -10 for both sides
-10w/-10=30/-10
w=-3
Answer: w=-3
If stereo that normally sells for $125 is on sale for $90 then price of the stereo has been reduced by 28%.
percentage, a relative value indicating hundredth parts of any quantity.
To find the percentage reduction in price, we need to calculate the difference between the original price and the sale price
Divide the difference by the originalprice, and then multiply by 100 to express the answer as a percentage.
The reduction price is difference between the One hundred twenty five and ninety.
The reduction in price is:
$125 - $90 = $35
So, the stereo has been reduced by $35.
To find the percentage reduction, we divide the reduction by the original price and multiply by 100:
$35/$125 x 100%
0.28×100
When zero point two eight is multiplied with hundred we get twenty eight.
= 28%
Therefore, the price of the stereo has been reduced by 28%.

Answer:
f(3) = 9
Step-by-step explanation:
Wherever you see an x on the right, put a 3 in for that x
f(x) = 2x^2 + x - 12
f(3) = 2*(3)^2 + 3 - 12
f(3) = 2*9 + 3 - 12
f(3) = 18 + 3 - 12
f(3) = 9
