Answer:
15/4, or 3 3/4 is your answer.
Step-by-step explanation:
Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other. Multiply 3/2 to both sides.
(3/2)(2/3)t = (5/2)(3/2)
t = (5/2)(3/2)
t = 15/4
15/4, or 3 3/4 is your answer.

Answer:
10x + 5y = 1325
x + y = 160 --> y = 160 - x
II in I
10x + 5(160 - x) = 1325
10x + 800 - 5x = 1325
5x = 525
x = 105
y = 160 - 105 = 55
Answer:
Step-by-step explanation:
x³ - 4x² + 7x - 28 = <u>x³ - 4x²</u> + 7x - 7*4
= <u>x²(x - 4)</u> + 7(x - 4)
= (x - 4 )(x² + 7)
