Answer:

Multiplication is one of the four elementary mathematical operations of arithmetic, with the others being addition, subtraction and division. Multiplication is marked as an "x." A mathematical operation performed on a pair of numbers in order to derive a third number called a product. For positive integers, multiplication consists of adding a number (the multiplicand) to itself a specified number of times. Thus multiplying 6 by 3 means adding 6 to itself three times.

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

What is the area of the composite shape<br> A pentagon is shown.
natali 33 [55]

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.a^{2} +b^{2} =c^{2}. so reverse of that for this problem would be c^{2} -b^{2} =a^{2} 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.✌

rafeal rides his bike down a hill. for each kilometer that he rides, his altitude changes by -10m. What is rafael's altitude rel
mrs_skeptik [129]

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.
