Answer:

The answer depends on how you count them; for example, are you allowed to count the same line segment multiple times to make multiple triangles out of the same segment, or must each line segment appear in only one triangle in your count?

Step-by-step explanation:

To draw a Jewish star, you really draw only two large triangles: one pointing up and the other pointing down. However, the overlap of these two triangles forms six additional smaller triangles at each tip in addition to a hexagon shape in the center.

If you allow line segments to be counted towards more than one triangle, then the number of triangles formed in the final symbol is 8, consisting of 2 large triangles and 6 smaller triangles.

Determine the value of a + b in the system of equations below. <br><br> 5a + 4b = 22<br> 7a-b= 11
dexar [7]

Answer:

We have a + b as;

2 + 3 = 5

Step-by-step explanation:

Here, we want go get the value of a and b

from the second equation, we can get an expression for b

We have this as;

7a - b = 11

Thus,

b = 7a - 11

Now, from here, we can substitute the value of b into the first equation

We have this as;

5a + 4(7a - 11) = 22

5a + 28a -44 = 22

33a = 22 + 44

33a = 66

a = 66/33

a = 2

Recall;

b = 7a - 11

substituting the value of a from above;

b = 7(2) - 11

b = 14 - 11

b = 3

lutik1710 [3]

Answer:

6 toppings

Step-by-step explanation:

The t in this equation represents the amount of toppings.

22 + 0.65t = 26

-22 -22

0.65t = 4

0.65t/0.65 = 4/0.65

t = 6

They could get 6 toppings and the total would be $25.90.
