Answer:

$\frac{3\sqrt{2} }{2}$

Step-by-step explanation:

Given

$\frac{\sqrt{2} }{2}$ + $\frac{2}{\sqrt{2} }$ ← rationalise the denominator by multiplying by $\frac{\sqrt{2} }{\sqrt{2} }$

= $\frac{\sqrt{2} }{2}$ + ( $\frac{2}{\sqrt{2} }$ × $\frac{\sqrt{2} }{\sqrt{2} }$ )

= $\frac{\sqrt{2} }{2}$ + $\frac{2\sqrt{2} }{2}$

= $\frac{3\sqrt{2} }{2}$

coldgirl [10]

Answer:

$6.75 and $4.50

Step-by-step explanation:

a) Jamal spent:

Isaiah spent:

3 (x - 2.25)

The equation is:

2x = 3(x - 2.25)

b) Solving the equation

2x = 3x - 6.75
3x - 2x = 6.75
x = 6.75

c) Jamal's items cost

$6.75 each

Isaiah's items cost

$6.75 - $2.25 = $4.50 each

-3 • (5x + 2y = 7)
-15x - 6y = -21
-2x + 6y = 9
__________
-17x = -12
x = 12/17
5(12/17) + 2y = 7
2y = 7 - 60/17
2y = 3.47
y = 1.735
