In a 45 - 45 - 90 right triangle, the hypotenuse is √2 · legs = hypotenuse, so legs=\frac{\sqrt{5}}{\sqrt{2}} and to rationalize the denominator all we have to do is multiply the numerator and denominator by √2. \frac{\sqrt{10}}{2}.

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is
antoniya [11.8K]
We can solve this system using elimination:

(x+y=24)3
3x+5y=100

3x+3y=72
-(3x+5y=100)
0x-2y=-28
y=14

We can then plug this back into one of the original equations:

x+14=24
x=10

We can check our answer by plugging this into both of the original equations:

10+14=24
24=24

3(10) + 5(14)=100
30+70=100
100=100

Therefore, there are 10 3-point questions and 14 5-point questions.

Pie

Step-by-step explanation:

Givens

Greeting Card = 3.79

Total Cost = 5.11

Post cards = x

Equation

Total Cost = Greeting Card + 4x

Solution

Substitute the gives into the equation

5.11 = 3.79 + 4x                       Subtract 3.79 from both sides

5.11 - 3.79 = 3.79 - 3.79 + 4x  Combine

1.32 = 4x                                  Divide by 4

1.32/4 = 4x/4

x = 33

Each post card costs 0.33 dollars
