Answer:
he invested $10,000 at 7% and $12,000 at 6%
Step-by-step explanation:
- There are 2 equations that appear from this problem
- X+Y=22,000 and 0.07x + 0.06y = 1420
- Lets start by simplifying X+Y=22000
Y = 22000 - x
- now plug this into the Y value for the other equation
0.07x + 0.06(22000-x) = 1420
0.07x + 1320 -0.06x = 1420
0.01x = 100
X = 10000
- now plug 10000 into x for the simplified equation
Y = 22000 - 10000
Y = 12000
Answer:
0
Step-by-step explanation:
11a + 9b + c + 2a
a constant is just a number...it has no variables (letters).
there are no constants in this expression
example :
3x + 2b + 7 + 4c + 2 x + 5 = 8
the constants in this are 7 and 2 constants are 5 and 8
Answer:
R(p) = -4p^2 + 300p when p=20.
R(p) = -4(20)^2 + 300(20)
R(p) = -1600 + 6000
R(p) = 4400
The mass when p=20 years is 4400.
Answer:
the answer is 11 quarters and 20 pennies
Step-by-step explanation: because it said 9 more pennies than quarters so 11 x .25 = $1.75 + $0.20 = $2.95
