Answer:

Yes

Step-by-step explanation:

-8x-2y<6 (I prefer to convert this into standard form y=mx+b)

-8x+8x-2y<8x+6

-2y/-2>8x+6/-2

y > -4x -3

2 > -4(3) - 3

2 > -12 - 3

2 > -15 True or Yes

Write a division problem that has a two digit quotient that is greater than 40 but less than 50.

trasher [3.6K]

Let

x--------> Dividend

y-------> Divisor

Q-------> Quotient

we know that

$\frac{x}{y} = Q$

solve for x

$x=Q*y$

$40 < Q < 50$

Examples

example 1

$Q=45\\ y=4$

Find the value of x

$x=45*4\\ x=180$

A division problem is equal to

$\frac{x}{y} =\frac{180}{4} \\\\ = 45$

example 2

$Q=42\\ y=10$

Find the value of x

$x=42*10\\ x=420$

A division problem is equal to

$\frac{x}{y} =\frac{420}{10} \\\\ = 42$

The side lengths of the Australian flag are in a ratio of 1:2. If the flag is 5 feet long, what is it’s height?

jonny [76]

height:length

1:2

x feet: 5 feet

You know the length and the ratio of the dimensions. From the ratio you know that the length is twice the height. So height = 5/2 = 2.5 ft.
