We need to do 3/4x5. 3/4 is the same as 0.75. 0.75x5= 3.75. If you put that back into a fraction it is 3 and 3/4. This means pearl needs to mix 3 and 3/4 teaspoons of plant food into the water.

1 gallon of water requires 3/4 teaspoon of plant food, so multiply 3/4 by 5

3/4  ×  5

Make 5 into a fraction

3/4  ×  5/1

Multiply the denominator by the denominator and the numerator by the numerator

 3   ×   5            15
----     ----    =   ------
 4   ×   1<span>             4

15/4  is an improper fraction, so make it a mixed fraction

15/4  =  3 and 3/4

Answer:

Pedro should mix 15/4  teaspoons or 3 and 3/4  teaspoons  of plant food into 5 gallons of water.</span>

Find the length of each side of the polygon for the given perimeter.<br> P = 48
Vaselesa [24]

Answer:

The top is 5

The right side is 5

The bottom is 2x = 2*5 = 10

The left is 5-2 = 3

Step-by-step explanation:

The perimeter is the sum of the sides

x+x+ 2x + x-2 = 23

Combine like terms

5x-2 = 23

Add 2 to each side

5x-2+2 = 23+2

5x = 25

Divide each side

5x/5 = 25/5

x = 5

The top is 5

The right side is 5

The bottom is 2x = 2*5 = 10

The left is 5-2 = 3

Find the length of ST
Andru [333]

Answer:

ST = 12

Step-by-step explanation:

By AA Similarity, triangles ASR and EST are similar.

The ratio of the lengths of the sides of triangle ASR to those of EST is 6/8 or 3/4.

\dfrac{SR}{ST} = \dfrac{3}{4}

Also,

SR + ST = 21

By a rule of proportions, you get

\dfrac{SR + ST}{ST} = \dfrac{3 + 4}{4}

\dfrac{21}{ST} = \dfrac{7}{4}

7ST = 4 \times 21

7ST = 84

ST = 12

-104=-8(k+8) <br><br> K = ?<br> Solution please if can?
maksim [4K]

Let's solve this question by step by step.

Layout equation.

−104=−8(k+8)

Step 1: Simplify both sides of the equation.

−104=−8(k+8)

−104=(−8)(k)+(−8)(8)(Distribute)

−104=−8k+−64

−104=−8k−64

Step 2: Flip the equation.

−8k−64=−104

Step 3: Add 64 to both sides.

−8k−64+64=−104+64

−8k=−40

Step 4: Divide both sides by -8.

-8k/-8=-40/-8

The answer for this problem is k=5.
