<u>On the first part, just replace the variables with the given number to check. </u>
1) 34 + 12 = 46 → <u>Correct</u>
2) 22 - 9 = 14 → <u>Incorrect</u>
3) 6 * 9 = 54 → <u>Correct</u>
4) 39 ^ 3 = 13 → <u>Correct</u>
<u />
<u>On the second part, simply change the symbols. Like this:</u>
5) 7 + k = 11 ⇒ 11 - 9 = k
<u>K = 2 </u>
6) p - 24 = 13 ⇒ 13 + 24 = p
<u> p = 37 </u>
7) b - 16 = 7 ⇒ 7 + 16 = b
<u>b = 23</u>
8)
+ m =
⇒
-
= m
<u>m = 13/30</u>

To get from 12 smores to 3 smores, you divide by 4. Therefore, you divide the amount of ingredients by 4 also, which is 12 ÷ 4 = 3 and 8 ÷ 4 = 2. So she needs 3 marshmallows and 2 Graham crackers for 3 smores. Hope this helped!
Answer:
B
Step-by-step explanation:
Part (a)
<h3>Answer: x = -8</h3>
------------------
Work Shown:
2(x-1) = 3(x+2)
2x-2 = 3x+6 .... distribute
2x = 3x+6+2 .... adding 2 to both sides
2x = 3x+8
2x-3x = 8 .... subtracting 3x from both sides
-x = 8
x = -8 ..... multiply both sides by -1
===========================================================
Part (b)
<h3>Answer: x = 5/11</h3>
------------------
Work Shown:
-4(2x-2) = 3(x+1)
-8x+8 = 3x+3 ..... distribute
-8x = 3x+3-8 .... subtract 8 from both sides
-8x = 3x-5
-8x-3x = -5 ... subtract 3x from both sides
-11x = -5
x = -5/(-11) .... divide both sides by -11
x = 5/11
In decimal form, this is approximately equal to 5/11 = 0.4545
Area of triangle = 1/2 x base x height
Given that base = 11 yards and height = 13 yards
Area of triangle = 1/2 x 11 x 13 = 71.5 yards²
Answer; 71.5 yd²
