The answer for this is 2.8
Answer:
I'm not going to give you an exact answer because there could be many different ones
Step-by-step explanation:
The equations can be rewritten as:
2x - 7 = 7y
-4x + 19 = 3y
then you just insert a value for x and get the answer.
The correct answer for this question is this one: "<span>147"</span>
Here's how to solve this problem.
Let <span>x = number of mystery books on the shelf </span>
<span>Let 3x = total number of books on the shelf </span>
<span>we are told that </span>
<span>x/5<10<x/4 </span>
<span>multiply by 20, </span>
<span>4x<200<5x </span>
<span>which means that </span>
<span>40<x<50 </span>
<span>So the number of mystery books can be any number between 41 and 49.
In other words, the possible total number of books could be three times the above numbers, 123, 126, 129,.... </span>
Choose the one that suits your answer choices.
Here are the following choices:
Which could be the number of books on the shelf?
A. 120 B 140 c 147 D 150
60 times 6 equals 360.
So the answer is $360
Answer:
-2
Step-by-step explanation:
This linear equation is in slope-intercept format, aka y=mx+b. This is where m=slope and b=y-intercept. In the following equation, -110 is the slope and -2 replaces b, meaning it is the y-intercept
