5/8 inches minus 1/2 inches ?

Kitty [74]

5/8 - 1/2
well first you have to get the denominator the same so you multiply 1/2 by for to were it is 4/8
so now you have 5/8 - 4/8
5/8 - 4/8 = 1/8
and you cant divide by 4 to reduce bc your already at 1 over something.

If a bug can flap its wings at a rate of 60 times in 2 seconds, how many times do they flap their wings in 2.604 minutes? Round

WITCHER [35]

Answer:

4,687.2 flaps

Step-by-step explanation:

#We calculate the number of flaps per second:

$Flaps/Second=\frac{60}{2}\\\\=30 \ flaps$

#Since one minute has 60 seconds, we will multiply our time by 60 seconds and then by flaps/second:

$Flaps=Rate \times time\\\\=30\times 2.604\times 60\\\\=4687.2\ flaps$

Hence, the bird makes 4,687.2 flaps in 2.604 minutes.

NO LINKS!! Use the method of substitution to solve the system. (If there's no solution, enter no solution). Part 11z

Roman55 [17]

Answer:

$(x,y)=\left(\; \boxed{-1,-8} \; \right)\quad \textsf{(smaller $x$-value)}$

$(x,y)=\left(\; \boxed{5,16} \; \right)\quad \textsf{(larger $x$-value)}$

Step-by-step explanation:

Given system of equations:

$\begin{cases}y=x^2-9\\y=4x-4\end{cases}$

To solve by the method of substitution, substitute the first equation into the second equation and rearrange so that the equation equals zero:

$\begin{aligned}x^2-9&=4x-4\\x^2-4x-9&=-4\\x^2-4x-5&=0\end{aligned}$
