Answer:
750/100 X 7 = 52.50
52.50 X 3 = $157.50
Step-by-step explanation:
divide principal amount by 100 then multiply by interest percentage. this gave 52.50
now multiply the interest amount by number of years
in this case 3
52.50 X 3 = $157.50
Answer:
72
Step-by-step explanation:
The length of the rectangle would be X2 - X1
The height of the rectangle would be Y2-Y1
Perimeter = 2 X length + 2 times height
The perimeter would be 2(X2-X1) + 2(Y2-Y1)
The first choice would be the correct answer.
4 - 8 = -4.
Note that 8 (in the equation) comes after 4 (also in the equation) so, that makes the answer negative. If you wrote the equation like this:
8 - 4 = 4. Then it would equal 4, not negative 4 as given.
So,
a = 8

- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
3x + y = 10
y = x - 2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: 3x + (x - 2) = 10
- Combine like terms: 4x - 2 = 10
- Isolate <em>x </em>term: 4x = 12
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x - 2
- Substitute in <em>x</em>: y = 3 - 2
- Subtract: y = 1
And we have our answer!
