Let x = amount invested in the 1st account
y = amount invested in the 2nd account
z = amount invested in the 3rd account
Because the total investment is $100,000, therefore
x + y + z = 100,000 (1)
Interest earned in one year from the accounts is $3,650, therefore
0.04x + 0.03y + 0.02z = 3,650
or
4x + 3y + 2z = 365,000 (2)
Because x = 5y, therefore obtain these 2 equations:
5y +y +z = 100,000
or
6y + z = 100,000 (3)
4*(5y) +3y + 2z = 365,000
or
23y + 2z = 365,000 (4)
Substitute z=1000,000 - 6y from (3) into (4).
23y + 2(100,000 - 6y) = 365,000
23y + 200,000 - 12y = 365,000
11y = 165,000
y = $15,000
Therefore
x = 5y = $75,000
z = 100,000 - 6y = $10,000
Answer:
The amounts invested are
1st account: $75,000
2nd account: $15,000
3rd account: $10,000
Outside
length is 7 inches
Outside Width
is 5 inches.
SOLUTION
Length of outside edge = 7 inches
Scale Factor: 1in = 2.5ft
New length of outside edge = (7 * 2.5)ft
New length = 17.5ft
Width of outside edge = 5 inches
Scale Factor: 1in = 2.5ft
New width of outside edge = (5 * 2.5)ft
New Width = 12.5ft
Therefore, the new dimension of the outside edges of the
frame is 17.5ft by 12.5ft
The answer will be $13,439.16
Answer:
32
Step-by-step explanation:
every time we are multiplying by -2 so if we do -16 x -2 we will get postive 32
B is the answer fam because I did this before and b was the answer
