How do you solve 5 3/7 ÷ 5/11
Artyom0805 [142]

Answer:

11 33/35

Step-by-step explanation:

5 3/7 = 5 × 7/7 + 3/7 = 35 + 37 = 38/7

38/7 ÷ 5/11 = 38/7 × 11/5 = 38 × 11/7 × 5 = 418/35

418/35 = 11 33/35

If h(x) = x – 7 and g(x) = x2, which expression is equivalent (g o h)(5)
Zanzabum
(goh)(x) = (g(x))(h(x)) = (x^2)(x-7) = x^3 -7x^2
then (goh)(5) = (5^3)-7(5)^2 = 124-7(25) = 124-175 = -51

Help with 6 a and b please
34kurt

Answer:

a) y=\frac{50}{x}

b) y=25 when x=2

Step-by-step explanation:

y=\frac{k}{x} since y varies inversely with x.

We need to find the constant, k.

Let's use a point (x,y) on the curve.

We are given an (x,y)=(5,10):

10=\frac{k}{5}

Multiply both sides by 5:

10(5)=k

50=k.

So the equation is:

y=\frac{50}{x}

What is y when x=2?

y=\frac{50}{2}

y=25
