The correct answer is A) it would be to the left of zero on the number line.
Positive numbers are to the right of zero on the number line.
The opposite of a positive number is a negative number.
Negative numbers are to the left of zero on the number line.
Answer:
A-1
Step-by-step explanation:
18-4x=7x+7
18=11x+7
11=11x
x=1
Answer:
Step-by-step explanation:
A system of linear equations can help solve questions like this, that don't give "any" clue as to how many people are on either a van or a bus. Here you just need to interpret the question; at the bottom, it says that <em>x</em> represents the number of students on vans and <em>y</em> represents the number of students on a bus. In other words, for each school, the total number of students going on the field trip are the number of students on vans and the number of students on buses. Hope this helps :D
For this case, the first thing we must do is define variables.
We have then:
n: number of cans that each student must bring
We know that:
The teacher will bring 5 cans
There are 20 students in the class
At least 105 cans must be brought, but no more than 205 cans
Therefore the inequation of the problem is given by:
Answer:
105 <u><</u> 20n + 5 <u><</u> 205
the possible numbers n of cans that each student should bring in is:
105 <u><</u> 20n + 5 <u><</u> 205
A) True
b) False
c) True
To solve this you would have just had to replace x with any number.
