Answer:
27
Step-by-step explanation
Sally = 4 x 3 = 12(left) + 15(spent) = 27
Lucy = 24(spent) + 3(left) = 27 (we dont multiply this part bc Lucy spent 9 more dollars than Sally, 3 x 3 is 9 which equals the difference)
Answer:
(4, 7) (third answer choice)
Step-by-step explanation:
In the system
y = x + 3
3x + y = 19
the first equation already gives y in terms of x. Thus we can substitute x + 3 for y in the second equation:
3x + (x + 3) = 19, which simplifies to:
4x = 16, yielding x = 4. Substituting 4 for x in the first equation, we get:
y = (4) + 3 = 7.
Thus, the solution is (4, 7) (third answer choice).
Step-by-step explanation:
• 10% of 5000
So, 10% of 5000 is 500
• 5% of 5000
So, 5% of 5000 is 250
Answer:
x = 5
Step-by-step explanation:
-7x - 3x + 2 = -8x - 8
-7x + 8x - 3x = -8 -2
-2x = -10
2x = 10
x = 5
