Answer:
2 marbles
Step-by-step explanation:
Lana has 3 bags with x marbles in each bag totaling 12 marbles
3x=12
Divide by 3
3x/3 =12/3
x =4
Each bag has 4 marbles
Markus has 3 bags with y marbles totaling 18 marbles
3y =18
Divide each side by 3
3y/3 =18/3
y =6
Each bag has 6 marbles
6-4 =2
There are 2 more marbles in Markus' bags than in Lara's
6)
3x + 27 - x + 6
answer: 2x + 33

7 [16 - 6 | 5 + ( 8 - 18 ) + 16 + 8 |]
7 [16 - 6 | 5 - 10 + 16 + 8 |]
7 [16 - 6 • 19]
7 [16 - 114]
7 [-98]
answer: -686
(this answer can possibly be wrong )
2)
8 - 11
answer: -3
3)
-7/3(6) + 9
14 + 9
answer: 23
4)
2(5) - 9
10 - 9
answer: 1
The slope is -1/2
Step by step
1) formula m=y2-y1/x2-x1
2) slope equals = -1+2/-8+6
3) 1/-2
4) answer is -1/2
Treat this as if the inequality sign was the same thing as an equal sign. Most of the equality rules apply to inequalities (with a few exceptions)
Subtract both sides by 4
Multiply both sides by 2
We want the unknown variable on the left side (because it looks nicer)
Answer:
2x^2+13x+20 is the simplified answer
