Answer:
Part A: B) 3
Part B: $40
4. -1
7. 5x + 6y
8. Part A: y = 20x
8. Part B: $300
9. e > 12000 pounds
Step-by-step explanation:
Part A: x = 5t + 5
20 = 5t +5
15 = 5t
t = 3
Part B: x = 5t + 5
x = 5(7) + 5
x = 35 +5
x = 40
4. 24 - 5^2
24 - (5*5)
24 - 25 = -1
7. 2x + 4y + 5 + 2y - 5 + 3x
2x + 3x = 5x
4y + 2y = 6y
5 + (-5) = 0
5x + 6y
8. Part A:
Total = y
Lawns = x
Amount = $20
so y = 20x
8. Part B:
y = 20x
y = 20(15)
y = 300
9. The elephant weighs more than 12000 pounds
Elephant = e
More than = >
Pounds = 12000
e > 12000 pounds
ANSWER
EXPLANATION
We need to use the Pythagoras Theorem to find the height of the triangle.
Take positive square root to get;
Area =½bh
10.25 x 4
20.5 x 2
41 x 1
Hope this helps :)
just follow the steps:
100-15 since it's 15 inches taller
=85
85/5 since it's 5 times the height of the kiwi
=17
The kiwi is 17 inches tall
