Is (6, 34) the solution to the system below?

y = 5x + 4 and x + y = 40

Circle your final answer. SHOW WORK as mathematical proof.

Answers

Answer 1
Yes.
(34)=5(6) + 4
34= 30 + 4
34 = 34

(6) + (34) = 40
40 = 40
Answer 2

Answer:

Yes

Step-by-step explanation:

y = 5x + 4

x + y = 40

x = 6

y = 34

34 = 5(6) + 4

34 = 30 + 4

34 = 34

34 + 6 = 40

88ft²

Step-by-step explanation:

Hey There

So first we want to find the area of the square

to do that we do 8x8 which equals 64

then we want to find the area of the triangle

to do so we multiply the base (8) and the height and divide that by 2

8x6=48

48/2=24

then we add the two together

24+64=88

88ft² is your answer :)

To find the are of a triangle, you multiply the dimensions as you would a rectangle, but divide the product by 2.

Example:

The dimensions of triangle B are 4 and 9.

4x9=36

Now divide.

36/2=18

So the area of triangle B is 18.
