The first thing you should know is that the rate of each one is:
Kaitlyn = 1/6
Mark = 1/8
Then,
d = number of days.
The equation then if they work together is:
1 / 6d + 1 / 8d = 1
answer:
the equation for number of days it would take to build the sheld together is
1 / 6d + 1 / 8d = 1

Kai:
6 days = 1 shed
1 day = 1/6 shed

Mark:
8 days = 1 shed
1 day = 1/8 shed

Together:
1 day = 1/6 + 1/8 shed

Ans: 1/6d + 1/8d = 1

Simplify 5+2{y-4[3x+7(2-x)]}

gregori [183]

Answer:

The answer to your question is: 32 x + 2y - 107

Step-by-step explanation:

Simplify 5+2{y-4[3x+7(2-x)]}

5 + 2 { y - 4[ 3x + 14 - 7x ]}

5 + 2 { y - 12x -56 +28x }

5 + 2y - 24 x - 112 + 56x like terms

32 x + 2y - 107

Solve the equation or formula for the indicated variable a=4b^5h

melisa1 [442]

Given that the formula we are required to solve for h:
a=4b^5h
to solve for h we divide both sides by 4, this will give us:
a/4=(4b^5h)/4
a/4=b^5h
next we divide both sides by b^5, this will give us:
a/(4×b^5)=(b^5h)/b^5
a/(4b^5)=h
hence the answer is:
h=a/(4b^5)

Find the value of x from this adjoining figure

Fiesta28 [93]

Answer:

$x=15^\circ$

Step-by-step explanation:

Please refer to the attached figure for labeling of given diagram:

We are given the following angles:

$\angle AOC = 3x^\circ\\\angle BOD = 2x^\circ\\\angle EOF = 7x^\circ$

Angles opposite to each other when they are formed by crossing of two lines are known as vertically opposite angles. And vertically opposite angles are always equal to each other.

Using property of vertically opposite angles:

$\angle EOF = \angle AOB = 7x^\circ$

Line CD is a straight line, so $\angle COD = 180^\circ$

Also,

$\angle COD = \angle COA+\angle AOB+\angle BOD = 180^\circ\\\Rightarrow 3x + 7x + 2x=180^\circ\\\Rightarrow 12x =180^\circ\\\Rightarrow x = \dfrac{180}{12}\\\Rightarrow x = 15^\circ$

Hence, answer is $x = 15^\circ$ .

Which ordered pair is a solution to the graphed inequality?

aleksandr82 [10.1K]

Given:

The graph of a system of inequalities.

To find:

The ordered pair which is a solution to the graphed inequality.

Solution:

The boundary lines are:

$x-2y=4$

$2x-y=4$

From the given graph it is clear that only point (3,1) lies in the shaded region.

Points (2,-1) and (4,0) lie on the boundary line $x-2y=4$ but the boundary line is dotted. It means the points on the line are not in the solution set.

point (0,-1) does not belong to the shaded region.

Therefore, the correct option is A.
