Answer:
1: 6
2: 1,2,3
3: 4m-1>5m-4
4: Not enough data
5: n = 11
6: The ceiling is lower than 3m
7: G = 7
8: C = 18
9: p + 18 = 41; p = 23
10: D = 100t
Step-by-step explanation:
Question 1:
5*2+x/2-7
5*2+6/2-7
10+6/2-7
10+3-7
13-7
6
Question 2:
4*2<16
8<16 True
4*1<16
4<16 True
4*3<16
12<16 True
4*4<16
16<16 False
Question 3:
Let's plug in 1 for m
4*1-1____5*1-4
4-1_____5-4
3_____1
3>1
Question 4:
You did not give an equation, so I cannot answer.
Question 5:
2*11 + 5 =27
22 + 5 = 27
27 = 27
So n = 11
Question 6:
x<3
The ceiling is lower than 3m because x<3
Question 7:
5.1g = 35.7
5.1g/5.1=35.7/5.1
g = 7
Check: 5.1 * 7 = 35.7
Question 8:
36 + c = 54
36 + c -36 = 54 - 36
c = 18
Check: 36 + 18 = 54
Question 9:
p + 18 = 41; p = 23 is correct because the number of paperback books plus the number of hardcover books would equal the total number of books sold. Check: 23 + 18 = 41
Question 10:
d=100t is correct because each time t goes up one it goes up 100. Example: if it is at one hour, than it is 100, if it is at 3 hours, than d = 100*3 = 300, which is the same pattern as the table.
Hope this helps!
The expression is 50 + 0.25t.
<h3>How to compute the value?</h3>
It should be noted that from the information, the cell phone costs $50 a month plus $0.25 for each text message (t).
The expression will be:
= 50 + 0.25(t)
= 50 + 0.25t
Therefore, the expression is 50 + 0.25t.

Answer:
72 acorns.
Step-by-step explanation:
9 (acorns per pile)
*
8 (piles)
We need to account for both x values on either side of the length, and width.
Thus, the length becomes 10 + x + x = 10 + 2x
and the width becomes 5 + x + x = 5 + 2x
For the second question, I'm assuming we don't account for the area that is covered by the garden.
Then we can say that the path is measured by: (5 + 2x)(10 + 2x) - 50, which is the area of the garden itself.
(5 + 2x)(10 + 2x) - 50 = 54
Expanding the brackets:
x = -9, or x = 3/2
Since x > 0, then x ≠ -9
Thus, the only x-value we can take is x = 3/2
120+25x=45x
Step 1: Simplify both sides of the equation.
25x+120=45x
Step 2: Subtract 45x from both sides.
25x+120−45x=45x−45x
−20x+120=0
Step 3: Subtract 120 from both sides.
−20x+120−120=0−120
−20x=−120
Step 4: Divide both sides by -20.
−20x
−20
=
−120
−20
