Answer:

-3 7/8, -7/9, -3/5, 1/2, 1 4/5

Step-by-step explanation:

Start with the negatives because lower on the scale.3 has the most negative number so it’s first. To compare 7/9 and 3/5 you have to make the denominator the same (45). 1 is bigger than a half so half is next then 1 4/5.

Answer:

first option

Step-by-step explanation:

Given

(3x² + 2x - 3)(x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

3x²(x - 1) + 2x(x - 1) - 3(x - 1) ← distribute parenthesis

= 3x³ - 3x² + 2x² - 2x - 3x + 3 ← collect like terms

= 3x³ - x² - 5x + 3

Boris invested his savings in two investment funds. The $12,000 that he invested in fund a returned a 6% profit the amount that

Sedbober [7]

Answer:

$4000

Step-by-step explanation:

Let B represent amount invested in account 'b'.

We have been given that an amount of $12,000 that Boris invested in fund a returned a 6% profit.

So the profit earned from fund 'a' would be $12,000\times\frac{6}{100}=12,000(0.06)$ .

We are also told that the amount that he invested in fund b returned at 2% profit. So the profit earned from fund 'b' would be $B\times\frac{2}{100}=B(0.02)=0.02B$ .

Further, both funds together returned a 5%. We can represent this information as:

$(12,000+B)\times\frac{5}{100}=0.05(12,000+B)$

Now, we will equate profit earned from account 'a' and 'b' with profit earned from both accounts as:

$12,000(0.06)+0.02B=0.05(12,000+B)$

$720+0.02B=600+0.05B$

$600+0.05B=720+0.02B$

$600-600+0.05B=720-600+0.02B$

$0.05B=120+0.02B$

$0.05B-0.02B=120+0.02B-0.02B$

$0.03B=120$

$\frac{0.03B}{0.03}=\frac{120}{0.03}$

$B=4000$

Therefore, Jason invested $4000 in fund 'b'.

Mr McKay bought b boxes of crackers for $3 each and p pounds of cheese for $4 per pound. How much did he spend in all.

malfutka [58]

In normal circumstances, you would multiply the amount of boxes by 3, and the amount of pounds by 4. So you do the same here:
3b + 4p

Mr McKay spent 3b + 4b in total
