Answer:

x = 80

Step-by-step explanation:

We know the sum of the angles of a triangle is 180

x+y+z = 180

Since this is an isosceles triangle y=x

x +x + z = 180

We also know that x = 4z

Writing this in terms of x since we want to find angle x    

z = 1/4x

x+x+1/4x = 180

Combine like terms

2x +1/4x = 180

Multiply each side by 4 to get rid of fractions

4(2x +1/4x) = 180*4

8x +x =720

9x = 720

Divide by 9

9x/9 = 720/9

x = 80

Answer:

C) 80

Step-by-step explanation:

Let the base angles be 4x

Vertex would be x

Total angle in a triangle = 180

x + 4x + 4x = 180

9x = 180

x = 20

4x = 80

The ratio of collectible cards Kyle owns to cards that Zeona owns is 3:2. Zeona has 36 cards. How will the ratio of Kyle’s cards
blsea [12.9K]

Answer:

It wouldn't.

Step-by-step explanation:

With the ratio, since Zeona has 36 cards, Kyle must have 54. If they each sold half, Kyle would have 27 and Zeona would have 18. So, the ratio would still be 3:2.

If 5 pizzas cost $60, how much will 9 pizzas cost?<br> A $98<br> B $108<br> $110<br> D $112
frozen [14]

We can find the cost of ONE pizza, by dividing the price (60) by the amount (5):

60 / 5 = 12.

So each pizza costs 12 dollars, now to multiply that by 9:

12 * 9 = 108.

9 Pizzas cost 108 dollars.

Azul has 4 green picks and no orange picks you add orange picks so that there are 2 orange picks for every 1 green pick how many
tino4ka555 [31]

Answer:

There would be 12 total picks.

Step-by-step explanation:

In order to find this, create a proportional equality in which the top of the equation is the number of orange picks and the bottom is the number of green picks.

2/1 = x/4

Now we cross multiply to find out the total number of picks.

1*x = 4*2

x = 8

Now that we have the number of orange picks, we add to the number of green picks for the total number.

4 + 8 = 12
