Answer:
a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.
b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:
315/x = 70/100
This is because 315 is part of the whole and is 70% of the value of x.
Step-by-step explanation:
Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.
Answer:
I think the answer is 3.8.
Step-by-step explanation:
Because there is 0.6 for the blue paint and 0.4 for the white paint, and p=red paint. If you divide all 3 of them equally into 2 jars, you have add 0.4 and 0.6 together and then divide by 2, then substract it from 2.4. You will get 1.9, then multiply 1.9 by 2, that is how much Henri and Talia used for the red paint, which is 3.8 liters.
Answer:
B) x^2 - 3/ 3x
Step-by-step explanation:
As, f(x) - g(x) = x/3 - 1/x
So, x^2/ 3x - 3/ 3x
= x^2 - 3/ 3x
Listen well. 8•5=40. 40/2=20 you divide by two because that’s the formula [bh/2]. 20•9 since 9 is the side measurement
A-2b=-10
b=-10-a.
Hope this is the answer
