Answer:
Step-by-step explanation:
In order to solve this problem, we just need to translate mathematically what the problem is talking about. First, we know that:
x=# of hours she spent running on her wheel.
y = # of hourse she spent scratching at her cage.
So, let's split the problem into little chunks of information that will be easier to translate. This is split it into sentences.
So first:
Julie's pet hamster Zoe kept Julie awake for at least an hour running on her exercise wheel and scratching at the corner of her cage. This means that the least amount of time Julie was awake as an hour in total, so this can be written as an inequality like this:
time spent running + time spent scratching is less than or equal to 1 hour
next,
Zoe ran on the wheel at least twice as long as she scratched at the quarters of her cage.
This is:
and finally, she spent more than 1/4 of an hour running on her wheel.
so the system of inequalities is the following:
Answer:
The value of x = 9
Step-by-step explanation:
∵ The figure has right angle and a line ⊥ from the right angle to the hypotenuse
∴ There is a relation between the ⊥ line and the two parts of the hypotenuse
∴ (⊥)² = multiplication of the two parts of the hypotenuse
∴ (6)²= 4 × x
∴ 36 = 4 × x
∴ x = 36/4 = 9
Answer:
$1.5
Step-by-step explanation:
This would be solved using a simultaneous equation
let tacos = t
drink = d
3t + d = 7 -- eqn 1
2t + 2d = 8 -- eqn 2
Multiply equation 1 by 2 to derive equation 3
6t + 2d = 14 eqn 3
Substract equation 2 from equation 3
6t + 2d = 14 -- eqn 3
-
2t + 2d = 8 -- eqn 2
= 4t = 6
solve for t
6/4 = 1.5
= $1.5
