Answer:
Im not sure but i will try but im going to say like 115
Step-by-step explanation:
1. x+5y=8
2x- 5y=1 What you do is find the number/variable that are the same( here is is the +5y and -5y. You want them to be opposites(-,+) so that they cancel each other out. if they are not opposites, then multiply one equation by a negative sign to change it. Cross out the 5y's. Now you can combine like terms-x+2x=3x, and 8+1=9, so now your equation will look like this:
3x=9
x=9/3
x=3
now take x=3 and plug it into the first equation to solve for y. x+5y=8, so 3+5y=8
5y=8-3
5y=5
y=5/5
y=1
(3,1) are your answers.
now do the same with the other problems.
Answer:
55 pages
Step-by-step explanation:
Knowing that the <em>book holds 600 cards and 6 cards/page</em>, we can tell that there are <em>100 pages</em>.
From that, we know that 45% are empty, which means <em>55% of all of the pages have cards</em>.
55% of 100 is 55. Therefore, 55 pages have baseball cards.
Step-by-step explanation:
Step 1:
Let us consider the given expression
On Right Hand Side of equation,
Using BODMAS rule, we could get 2.4 as value.
Step 2:
Now let us consider the Left Hand Side of equation and solve it
which will be equal to 2.4.
