Answer:
= -1 1/5
Step-by-step explanation:
-3 3/5 ÷ 3
change -3 3/5 into an improper fraction
-3 3/5 = - (5*3+3) /5 = -18/5
-18/5 ÷ 3
copy dot flip
-18/5 * 1/3
rewrite to make the math simple
-18/3 * 1/5
-6 * 1/5
-6/5
now change this back to a mixed number
5 goes into 6 once with 1 left over
=-1 1/5
Solve algebrically 3x - 4y = -24 and x + 4y = 8 is x = -4 and y = 3
<u>Solution:</u>
We have been given two equations which are as follows:
3x - 4y = -24 ----- eqn 1
x + 4y = 8 -------- eqn 2
We have been asked to solve the equations which means we have to find the value of ‘x’ and ‘y’.
We rearrange eqn 2 as follows:
x + 4y = 8
x = 8 - 4y ------eqn 3
Now we substitute eqn 3 in eqn 1 as follows:
3(8 - 4y) -4y = -24
24 - 12y - 4y = -24
-16y = -48
y = 3
Substitute "y" value in eqn 3. Therefore the value of ‘x’ becomes:
x = 8 - 4(3)
x = 8 - 12 = -4
Hence on solving both the given equations we get the value of x and y as -4 and 3 respectively.
Answer:
4752 pages!
Step-by-step explanation:
Each page of a (1) scrapbook has 144 square inches. So, in total it will be 4752, because there's 13 students. You do 13x144 since there's 13 students and each scrapbook contains 144 square inches. Hope this helps! Have a great day <3
