Answer:

y = 3/8 x -3

Step-by-step explanation:

3x - 8y = 24

Solving for y

Subtract 3x from each side

3x-3x - 8y =-3x+ 24

-8y = -3x+24

Divide each side by -8

-8y/-8 = -3x/-8 +24/-8

y = 3/8 x -3

Answer:

$y=\frac{3}{8} x-3$

Step-by-step explanation:

To solve for y, we want to isolate it. This means subtracting 3x from both sides:

-8y = 24 - 3x

Now, to get y, we divide both sides by -8 to get rid of the current coefficient of y:

$y=\frac{24-3x}{-8} =-3+\frac{3}{8} x$

Thus, the answer is $y=\frac{3}{8} x-3$ .

Hope this helps!

write each of the following fraction as equivalent fractions with a denominator of 10 a. 1/2 b. 1/4 c. 3/30 d. 12/30

monitta

9514 1404 393

Answer:

a. 5/10

b. 2.5/10

c. 1/10

d. 4/10

Step-by-step explanation:

To find the numerator, multiply each fraction by 10.

a. (1/2)(10) = 5, so 1/2 = 5/10

b. (1/4)(10) = 2.5, so 1/4 = (2.5)/10 or (5/2)/10

c. (3/30)(10) = 1, so 3/30 = 1/10

d. (12/30)(10) = 4, so 12/30 = 4/10

A store sells flower arrangements at a cost of $28 each. Which statements are true regarding the price of the arrangements? Chec

Maru [420]

Let's check each case to determine the solution to the problem.

we know that

The cost of each flower arrangements is $\$28$

Statements

case A) If the price is marked down by $10$ percent, the new price will be $\$25.20$

we know that

If the price is marked down by $10$ percent

then

the new price will be

$10\%= \frac{10}{100} =0.10$

$(1-0.10)*\$28=0.90*\$28 \\= \$25.20$

$\$25.20=\$25.20$

therefore

The statement case A) is True

case B) If the price is marked down by $25$ percent, the new price will be $\$21$

we know that

If the price is marked down by $25$ percent

then

the new price will be

$25\%= \frac{25}{100} =0.25$

$(1-0.25)*\$28=0.75*\$28 \\= \$21$

$\$21=\$21$

therefore

The statement case B) is True

case C) If the price is marked down by $50$ percent, the new price will be $\$19$

we know that

If the price is marked down by $50$ percent

then

the new price will be

$50\%= \frac{50}{100} =0.50$

$(1-0.50)*\$28=0.50*\$28 \\= \$14$

$\$14 \neq \$19$

therefore

The statement case C) is False

case D) If the price is marked down by $35$ percent, the new price will be $\$18.20$

we know that

If the price is marked down by $35$ percent

then

the new price will be

$35\%= \frac{35}{100} =0.35$

$(1-0.35)*\$28=0.65*\$28 \\= \$18.20$

$\$18.20=\$18.20$

therefore

The statement case D) is True

case E) If the price is marked down by $40$ percent, the new price will be $\$29.80$

we know that

If the price is marked down by $40$ percent

then

the new price will be

$40\%= \frac{40}{100} =0.40$

$(1-0.40)*\$28=0.60*\$28 \\= \$16.80$

$\$16.80 \neq \$29.80$

therefore

The statement case E) is False
