Mathematics

Leto [7]3 years ago

Answer:

1. x = 10

2. x = 8

3. x = 7

Step-by-step explanation:

1. Sum of Angles in a triangle = 180

(6x + 3) + (5x - 7) + 74 = 180

11x - 4 + 74 = 180

11x + 70 = 180

Subtract 70 from both sides

11x = 110

Divide both sides by 11

x = 10

2. (8x + 1) + (7x + 14) + 45 = 180

15x + 15 + 45 = 180

15x + 60 = 180

Subtract 60 from both sides

15x = 120

Divide both sides by 15

x = 8

3. We first have to get the 3rd angle: 180 - Exterior angle = 3rd angle

180 - 118 = 62

Now we can find the value of x

10x + (6 + 6x) + 62 = 180

16x + 68 = 180

Subtract 68 from both sides

16x = 112

Divide both sides by 16

x = 7

Owen’s parents were planning a birthday party for him. They have $20.00 to spend on goodie bags. They need to buy 6 goodie bags
Dimas [21]

Answer:

Yes, they can buy all the bags.

Step-by-step explanation:

Owen's parents need to buy 6 bags for $2.49 each.

So, we need to calculate the total price:

$2.49 * 6 = $14.94

Since the bags cost $14.94, and Owen's parents have $20.00, they have enough money to buy all 6 bags. 14.94 < 20.00

Hope this helps!
