The sum of a number in 6 ?? algebraic expression

Mathematics
1 answer:
Leokris [45]3 years ago
4 0
I'm guessing you meant the sum of a number AND 6? If so:
x+6=y or just x+6

x is a variable for "a number" and you add 6 to it. The y on the other side of the equals sign is because the sum (number you get when adding) is unknown due to the value of the x variable being unknown.

The height of a trapezoid is 26 yards and the bases are 14 and 30 yards. What is the area (in square yards)?
faust18 [17]

Answer: 572 yards

Step-by-step explanation:

The equation to find the area of a (base1 + base2) x height/2

The two bases are 14 and 30. Add them up to get 44.

Then, times that by the height. You get 1,144.

Lastly, divide 1,144 by 2. You get 572.

I hope this helped!

Madelyn has x nickels and y dimes, having a maximum of 15 coins worth no
aliina [53]

9514 1404 393

Answer:

 2 nickels, 9 dimes

Step-by-step explanation:

When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the <em>unshaded</em> area the solution space. Here, the vertices of the triangular solution space are ...

  (2, 9), (2, 13), (6, 9)

Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.

__

Three solutions are shown:

  (x, y) = (2, 9), (3, 10), (4, 11)

An office supply company sells two types of fax
Phantasy [73]

14 of the machine that cost $150 was sold and 8 of the machine that cost $225 was sold.

To solve this problem, we would write a system of linear equations.

  • Let x represent the machine that cost $150
  • Let y represent the machine that cost $225

We can proceed to write our equations now.

x + y = 22...equation(i)\\150x + 225y = 3900...equation(ii)

From equation 1

x+ y = 22\\x = 22 - y...equation (iii)

<h3>The Value of Y</h3>

put equation (iii) into (ii)

150x + 225y =3900\\x = 22-y\\150(22-y)+225y=3900\\3300-150y+225y=3900\\3300+75y=3900\\75y=3900-3300\\75y=600\\75y/75=600/75\\y=8

<h3>The Value of X</h3>

Since we know the number of y, we can simply substitute it into equation (i) and solve.

x + y = 22\\x + 8 = 22\\x = 22-8\\x = 14

From the calculations above, 14 of the machine that cost $150 was sold and 8 of the machine that cost $255 was sold.
