Two equations can be generated from the equation above, one for Package A and the other for Package B.
(Package A) 3x + 2y = 18
(Package B) 8x + 6y = 50
Solving simultaneously for the values of x and y gives, x = 4 and y = 3. Hence, each birthday card costs $4.
X=15
Y=3
2(15)=30
3(3)=9
30+9=39
Answer:
n = 25/2
Step-by-step explanation:
First, you would want to subtract 7 from both sides of the equation. That would cancel the 7s out and 12-7 = 5. So now the equation looks like this: 2/5n = 5. Next, you would multiply both sides by 5/2, which is the reciprocal of 2/5. Now you have n= 5*(5/2). Lastly, you would just want to multiply 5*5 to get 25 and the 2 will just stay the same. So n = 25/2.

Answer:
4. 16.5 minutes 2508 words - Robert
5. 60 words (c)
6.I don't really know sorry :)
Step-by-step explanation:
4. 304 ÷ 2 = 1 minute 152 words - Robert
2508 ÷ 152 = 16.5 minutes 2508 words - Robert
5. 152 × 20 = 3040 words - Robert
483 ÷ 3 = 1 minute 161 words - Michaela
161 × 20 = 3220 words - Michaela
316 ÷ 2 = 1 minute 158 words - Laura
158 × 20 = 3160 words - Laura
= 3220 - 3160
= 60 words (c)
