Step-by-step explanation:
y + 1 = -(x+5)
y + 1 = -x - 5
y = -x - 6
x + y = -6
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
Answer:
the answer should be B
Step-by-step explanation:
the first part is basically finding the difference between the terms, as we know that d=T2-T1
so by comparing the T2-T1 and T3-T2 we can find the difference with the two variables h and k
afterwards do the same with T4-T3 and T3-T2, comparing them and you will get another equation
now that you have two equations, you can do simultaneous equation to get the answers
hope i helped :D
<span>well congruent means they must be equal so since from point G to point J is -3 spaces you would just need to find another segment that is also -3 spaces, JM. For the second question i think you mean find the midpoint between NH, and if so you would need to figure out 0 - 6, which gives you -3 which is located at point K. Hope this is the right one.</span>
