<span>△ABC is similar to △DEF. We can prove this by finding the missing angle measures.

C=180-(30+64)
C=180-94
C=86

E=180-(30+86)
E=180-116
E=64

Since A=30 and D=30, B=64 and E=64, and C=86 and F=86, the triangle are similar.

Juliette [100K]

Simplify 7/20 to decimals by dividing.

7 divided by 20= 0.35

Rose bought 0.35 kilograms of candy and 0.4 kilograms of fruit.

So, she bought more fruit, since 7/20 is less than 0.4.

I hope this helps :)

Answer:

Adult: 50 tickets

Child: 34 tickets

Step-by-step explanation:

Let a be the amount of adult tickets

Let c be the amount of child tickets

Equation:

a + c = 84

14a + 9c = 1,006

Step 1: Multiply a + c = 84 with -9, to canceled c.

-9 (a + c = 84)    →  -9a - 9c = -756

14a + 9c = 1006 → 14a + 9c = 1006

Step 2: Combined the 2 equation together, and solved it.

-9a - 9c = -756

<u>14a + 9c = 1006</u>

       <u> 5a</u> = <u>250</u>

        5        5

           a = 50

Step 3: Plug 50 into the one of the equation, and solved it.

a + c = 84 → 50 + c = 84

                  <u>-50         -50</u>

                            c = 34

Answer: Adult tickets (a) = 50 and Child tickets (c) = 34

To check the answer plug the two number into the equation ( Make sure to add 50 for a and 34 for c).
