Add 1/4a to both sides
-4= 8/4a-3
Simplify
-4=2a-3
Add 3 to both sides
-1=2a
Divide both sides by 2
-1/2=a
Final answer: a=-1/2
Answer:
37in.^2
Step-by-step explanation:
So if the triangles at the top have a hypotenuse of 5, and a length of 4, then doing reverse Pythagorean theorem, you find out that the width is 3.
. so reverse of that for this problem would be 
and if we plug it in, we get 25 -16=9 and the square root of 9 is 3. so if we find the are of the triangle, 3*4*1/2=6 and there are 2 triangles so 12 for both triangles. The square is 5*4=20. and the smaller triangles on the side are 1*5*1/2=2.5, and there are 2 traingles so 2.5*2= 5. So 5+20+12=37. You can do this on most calculators, and please put my answer as the brainliest.✌
The answer is -60.
Why is this so??
The information we have here is that Rafeal rode his bike downhill by 6 kilometers.
Every kilometer he rides his bike, the altitude declines by 10m (meters)
let <em>m</em> represent how many meters the altitude declined.
If there is a positive number (ex. 2) multiplied by a negative number (-2), The result will be negative (-4) and vice-versa.
Same goes with division. positive number (4) divided by negative number (-2), the result will be a negative quotient.
<em>Therefore, the answer would be -60m, or -60 meters.</em>

Answer:
Total Price = 1.07(0.65x)= 0.6955x.
Step-by-step explanation:
The discount percentage is, <em>d</em>% = 35%.
The sales tax percentage is, <em>s</em>% = 7%.
The variable <em>x</em> represent the original cost of the item(s).
The discount is subtracted from the original amount.
So, the discounted amount will be, 0.65x.
And the sales tax is added to the original amount.
So, the value of tax plus price will be, 1.07x.
Then the final price of the item(s) will be:
Total Price = 1.07(0.65x)= 0.6955x.
