The answer is
-28!
(8+(-3))(-5 3/5)
when there’s a + in front of an expression in parenthesis, the expression remains the same.
(8-3)x(-5 3/5)
convert the mixed number to an improper fraction.
(8-3)x(-28/5)
subtract the numbers
5x(-28/5)
multiplying a positive and a negative equals a negative: (+)x(-)=(-)
-5x28/5
reduce the numbers with the greatest common factor 5
-28

Solve by Elimination:<br>11. 3x - 3y - 2 = 6 & 4x - 5y - 3 = 4

rosijanka [135]

Answer:

x = 6.33, y = 3.67 to the nearest hundredth.

Step-by-step explanation:

3x - 3y - 2 = 6

4x - 5y - 3 = 4 Simplifying these 2 equations:

3x - 3y = 8 (A) Multiply by by 5

4x - 5y = 7 (B) Multiply by by -3

15x - 15y = 40

-12x + 15y = -21 Adding:

3x = 19

x = 19/3 = 6.33

so y = (8 - 3 *6.33 ) / - 3 (from Equation B )

= 3.67.

Emily purchased lemons for $600. She sold 3/4 of these at a loss of 20% and the remaining at a gain of 20%. How much percent doe

MAVERICK [17]

Answer:

10%

Step-by-step explanation:

Given: CP of lemon is $600.

3/4 of lemon sold at 20% loss

Remaining lemon at 20% gain.

Considering the quantity of lemon remain constant.

Cost price of 3/4 of lemon= $\frac{3}{4} \times 600= \$450$

As given, 3/4 of lemon sold at 20% loss.

∴ Selling price of $\frac{3}{4}\ of\ lemon= 450- \frac{20}{100}\times 450$

Selling price= $450- 90= \$ 360$

Hence, selling price of 3/4 lemon is $360.

Now, the cost price of remaining lemon $(1-\frac{3}{4} )= (\$ 600-\$ 450)$

∴ The cost price of $\frac{1}{4}\ lemon = \$ 150$

As given, remaining $\frac{1}{4} lemon\ sold\ at\ gain\ of\ 20\%$

∴ Selling price of $\frac{1}{4} \ lemon= (150\times \frac{20}{100}+150)$

Selling price of $\frac{1}{4} \ of\ lemon= (30+150)$

Hence, selling price of 1/4 lemon is $180

Loss\profit percent= $\frac{(SP-CP)}{CP} \times 100$

∴ Loss\profit percent= $\frac{60}{600} \times 100= 10\%$

Hence, the loss percentage is 10%
