Answer:

$y = \frac{6 - 4x}{9}$

Step-by-step explanation:

$6 = 4x + 9y \\ 6 - 4x = 9y \\ \frac{6 - 4x}{9} = \frac{9y}{9} \\ \\ y = \frac{6 - 4x}{9}$

hope this helps

Answer:

y = $\frac{6-4x}{9}$

Step-by-step explanation:

In equations, it's important to complete an operation to both sides because if it is only completed on one then the whole equation will change and the solution will be different so it's an important rule to remember when solving equations that you have to keep the equation balanced.

→ 6 = 4x + 9y

⇒ Minus 4x from both sides to isolate 9y

→ 6 - 4x = 9y

⇒ Make 'y' the subject

→ 9y = 6 - 4x

⇒ Divide both sides by 9 to isolate 'y'

→ y = $\frac{6-4x}{9}$

Hey cylindrical water tank is being filled with the hose. The depth of the water increases by 1 1/4 ft./h how many hours will it

irakobra [83]

First off, let's convert the mixed fractions to "improper", keeping in mind that the water is increasing every passing hour by 1 and 1/4.

$\bf \stackrel{mixed}{1\frac{1}{4}}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}}
\\\\\\
\stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}}\\\\
-------------------------------$

$\bf \begin{array}{ccll}
feet&hours\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{5}{4}&1\\\\
\frac{7}{2}&h
\end{array}\implies \cfrac{\quad \frac{5}{4}\quad }{\frac{7}{2}}=\cfrac{1}{h}\implies \cfrac{5}{4}\cdot \cfrac{2}{7}=\cfrac{1}{h}\implies \cfrac{5}{2}\cdot \cfrac{1}{7}=\cfrac{1}{h}
\\\\\\
\cfrac{5}{14}=\cfrac{1}{h}\implies h=\cfrac{14\cdot 1}{5}\implies h=\cfrac{14}{5}\implies h=2\frac{4}{5}$

What is the formula for area of a parallelogram?

kipiarov [429]

Answer:

The area of a polygon is the number of square units inside the polygon. Area is 2-dimensional like a carpet or an area rug.

Step-by-step explanation:

A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is:

A = B * H where B is the base, H is the height, and * means multiply.

The base and height of a parallelogram must be perpendicular. However, the lateral sides of a parallelogram are not perpendicular to the base. Thus, a dotted line is drawn to represent the height. Let's look at some examples involving the area of a parallelogram.

10. The sum of four consecutive integers is at least 18. What's the smallest consecutive integer to make this statement true?

Tju [1.3M]

Answer:

A. 3

Step-by-step explanation:

Let the integers be

(x+1)

(x+2)

(x+3)

Sum the integers

We have,

x+(x+1)+(x+2)+(x+3)=18

x+x+1+x+2+x+3=18

4x+6=18

Subtract 6 from both sides

4x-6=18-6

4x=12

Divide both sides by 4

4x/4=12/4

x=3

The smallest integer which is x is equal to 3

Check:

3+4+5+6=18
