Answer:
7
Step-by-step explanation:
The first step to solve this problem is to convert 1h 30min into just minutes. since there are 60 minutes in 1 hour you take 60 and add it ot the 30 extra minutes to get a total of 90.
Now, this question is asking you to find how many calories <u>per</u> minute she burns. When you are asked to find ___ per___ all you have to do is divide the first number by the second one. In this case you will divide calories by minutes.
630/90=<u>7</u>
Each multiple choice is worth 4 points, and X is the number of questions he get's right. For example, he gets 3 right: 4 x 3 = 12 points in total.
The same goes for the <span>word problems. Y represent the </span><span>the number of correct answers so, for example: he gets 4 right and each one is worth 8 points: 8x4
</span>
Since he needs to have a least 50 points, that means that he can have 50 or more than that. That can be written as: <span>≥
So, as i explained, the only possible option is D.</span>
<span> 4x + 8y ≥ 50 </span>
Answer:
yes she can
Step-by-step explanation:
y = 1.4(t) + 3
y = 1.4(15) + 3
y = 21 + 3
y = 24
since the total is 24, which is less than 25, she can talk for 15 minutes.
