Step-by-step explanation:
Since d is an decimal, the higher the power of d, the smaller the value.
Answer: x + 1 = 15
Step-by-step explanation:
solve -
x= 15 - 1
x = 14
x is a variable so it's not fix value in math
Call u the cost per uniform.
Since each of the 15 players gets one uniform and one basketball, we can make the following equation:
15u + 15(9) = 420
Solve this equation to get u=285/15= $19
Let x = Amount invested at 2%
y = Amount invested at 9%
x + y = 34000 ×(-0.02)→ -0.02x - 0.02y = -680
0.02x + 0.09y = 2570 → 0.02x + 0.09y = 2570
add the equations 0.07y = 1890
divide by 0.07 both sides y = 27000
x = 34000 - 27000 = 7000
ANSWER:
Invested at 2%: $7000
Invested at 9%: $27000
