Sorry I don't what the answer would be for A. But B would be (3,13)
Answer:
x <2
Step-by-step explanation:
9(2 + 3x) < 72
Divide each side by 9
9/9 *(2 + 3x) < 72/9
2+3x < 8
Subtract 2 from each side
2+3x-2 < 8-2
3x<6
Divide each side by 3
3x/3 <6/3
x <2
Answer:
x = 5/4
Step-by-step explanation:
5x - 6 = 4 - 3x
8x - 6 = 4
8x = 10
x = 5/4
The error is that -3x is moved across the = in an incorrect manner. You instead need to add the 3x across the = ending up with 5/4. Adding this across negates the negative which makes it 8x, the rest of the step are as follows.
Step-by-step explanation:
A. 36÷3=12 <em>$</em><em>12</em><em> </em><em>per</em><em> </em><em>ticket</em>
B. 8.25÷3=2.75 $2.75 per ice-cream cone<em> </em>so do 2.75×2=5.50 <em>$5.50 for 2 ice creams</em>
C. 0.99÷3=0.33 $0.33 per banana so do 0.33×5=1.65
<em>$</em><em>1.65</em><em> </em><em>for</em><em> </em><em>5</em><em> </em><em>bananas</em>
