Answer:

y = 75x

Step-by-step explanation:

In 4 months, it is at 300. In 9 months, it is at 675. An increase of 375 in 5 months. So you will multiply 75 x 5 to get 375 which is the exact amount.

Which expression is equivalent to Negative 2 and one-fourth divided by negative two-thirds? StartFraction 9 over 4 EndFraction d

Tanzania [10]

Answer:

The correct answer is:

Negative StartFraction 9 over 4 EndFraction divided by two-thirds

i.e.

$-\dfrac{9}{4} \div \dfrac{2}{3}$

Step-by-step explanation:

We have to find equivalent expression to :

Negative 2 and one-fourth divided by negative two-thirds

i.e.

$-2\dfrac{1}{4} \div \dfrac{2}{3} = ?$

We have to convert the the mixed fraction form $-2\frac{1}{4}$ to simpler $\frac{p}{q}$ fraction form.

Let us learn the concept first.

Mixed fraction is combination of a whole number and a fraction.

Expression of the form $a\frac{b}{c}$ have the following understanding:

c is the divider

b is the remainder and

a is the quotient.

To convert mixed fraction to fraction we can use the following:

$a\dfrac{b}{c} = \dfrac{a \times c+b}{c}$

$\therefore -2\dfrac{1}{4} = -\dfrac{(2 \times 4+1)}{4} = -\dfrac{9}{4}$

Hence

$-2\dfrac{1}{4} \div \dfrac{2}{3} = -\dfrac{9}{4} \div \dfrac{2}{3}$

i.e. the given expression is equivalent to :

Negative StartFraction 9 over 4 EndFraction divided by two-thirds

I'm thinking of a number. When I multiply by 8 and add –1, I get –17. What's my number?

frosja888 [35]

Say that you're thinking of number $x$

You multiply it by 8, and have $8x$

You add -1 (i.e., you subtract 1) and have $8x-1$

This equals -17, so you have

$8x-1=-17$

Add 1 to both sides

$8x=-16$

Divide both sides by 8:

$x=-2$

So, you were thinking of -2.
