I think you selected the right graph in the picture, I wouldn’t all the way take my word because I’m still learning this stuff in school but I’m pretty sure you already picked the right answer

A rectangle pool is 7 ft wide, it is 3 times as long as it is wide what’s the dimensions of the pool?

svetoff [14.1K]

The length is 3 times longer than the width (7)

3 x 7 = 21

the length is 21.

To find perimeter, add all sides together:

21 + 21 + 7 + 7 = 42 + 14 = 56

56 ft is your answer

hope this helps

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x

x = -y + 6

Step 2: Solve for y

Substitution

Substitute in x: y = 2(-y + 6)
Distribute 2: y = -2y + 12
Isolate y terms: 3y = 12
Isolate y: y = 4

Step 3: Solve for x

Define equation: x = -y + 6
Substitute in y: x = -4 + 6
Add: x = 2

If f(n) = -6n + 2, find f (5/6)

joja [24]

$f( \frac{5}{6} ) = - 6( \frac{5}{6} ) + 2 \\ f( \frac{5}{6} ) = - \frac{30}{6} + 2 \\ f( \frac{5}{6} ) = - 5 + 2 \\ f( \frac{5}{6} ) = - 3$

F) The marked price of a radio is 25 % above the selling price and the cost pr

Ostrovityanka [42]

Answer:

See explanation below.

Step-by-step explanation:

Let's say, $x$ represents the sale price of radio.

Then the marked price of the radio is $1.25x$

The cost price of the radio is $(1.25x)(0.70)$

The discount is simply 25% because the radio is being sold at 25% less then the marked price.

The gain percent is given as:

$\frac{x-1.25x\times \:0.70}{x}\times 100\\\\=12.5\%$

The radio is being sold at 12.5% gain.

Best Regards!
