What is 13x - 7y + 4x?

Mathematics
1 answer:
AlladinOne [14]3 years ago
4 0
17X-7Y. You add or subtract the same variables, in this case you only have two x's and one y. So you add them, because you have a addition sign. 13x+4x and you leave the Y alone, because there is not another Y variable.

3 balloon + 2 cakes = £19
horsena [70]

Step-by-step explanation:

3 balloons + 2 cakes = £19

=> 9 balloons + 6 cakes = £57 (multiply by 3)

9 balloons + 6 cakes = £57

- (9 balloons + 3 cakes = £42)

=> 3 cakes = £15, 1 cake = £5.

Therefore 3 balloons + 2(£5) = £19,

3 balloons = £9, 1 balloon = £3.

Hence each balloon is £3 and each cake is £5.

I need to know how to solve this PLEASE HELP MY TEST IS COMING UP
vivado [14]

Answer:

Step-by-step explanation:

Problem Green

Look at the white area. Where it meets the green border is the region of a quarter circle. So the quarter circle has a circumference of 1/4 * (2pi) r

r we are to take it, is 10/2 = 5 cm. It is 1/2 the side of the square..

So the perimeter of 1/4 green circle is (2/4) pi * 5 = 1/2 pi * 5 = 2.5*pi

There are 4 such areas.

So we have to multiply by 4

4 * 2.5 = 10 pi

The answer is 10*pi.

An alternate answer is 31.4 cm

Problem Two

<em><u>Large Circle</u></em>

Perimeter of the large circle = 2pi*r

r = 14 cm

Perimeter of the large circle= 2* pi * 14 = 28*pi

<em><u>Small Circle</u></em>

r = 14/2 = 7 cm

Perimeter = 2*pi*r

Perimeter = 2 * pi * 7

Perimeter = 14 pi

<em><u>Answer</u></em>

Total Perimeter = Small Circle + Big Circle

Total Perimeter = 14*pi + 28*pi = 42*pi

Your answer could be 42*3.14 = 131.88

If none of these are right, list your choices.

Find the equation of the line that contains the point p(3,5) and is parallel to the graph of 5x+y= -2
Zanzabum

9514 1404 393

Answer:

  5x +y = 20

Step-by-step explanation:

The equation of the parallel line will have the same x- and y-coefficients. The constant will be adjusted to make the equation true at the given point.

  5x +y = 5(3) +(5) = 20

The parallel line is ...

  5x +y = 20
