Answer:
The answer to your question is:
61.- 25
62.- 26
Step-by-step explanation:
61.-
2(5x + 5) + 2(2x) = 360
10x + 10 + 4x = 360
14x = 360 - 10
14x = 350
x = 350/14
x = 25
62.-
2(4x - 4) + 2(3x + 2) = 360
8x - 8 + 6x + 4 = 360
14x - 4 = 360
14x = 360 + 4
14x = 364
x = 364 / 14
x = 26
Answer:
,
Step-by-step explanation:
3/12, or 1/4, are defective.
he tests 4/12, or 1/3, fuses.
1/4(1/3) = 1/12 ?
i’m sorry if this is wrong. i’m not good at probability!
The amount in the passbook account is $11,000 and the money in the money market account is $8000
Let:
a represent the unknown amount in the passbook account
b represent the unknown amount in the money market account
From the question, the following information can be gathered:
- The money in the passbook account exceeds the amount in the money market account.
This information can be represented with this equation : a - b = 3000
- The interest paid on the passbook account exceeds the interest paid on the money market account.
This information can be represented with this equation : 0.08a - 0.10b = 80
The two equations gotten above would be solved using simultaneous equation and the elimination method
a - b = 3000 equation 1
0.08a - 0.10b = 80 equation 2
Multiply equation 1 by 0.08
0.08 - 0.08b = 240 equation 3
Subtract equation 2 from 3
0.02b = 160
Divide both sides of the equation by 0.02
b = 8000
Substitute for b in equation 1
a - 8000 = 3000
Add 8000 to both sides
a = 11,000
