Find an ordered pair (x, y) that is a solution to the equation. x-5y=5

timurjin [86]

Answer:

(x,y)=(0,-1)

Step-by-step explanation:

Observe that the equation $x-5y=5$ can be transformed in the equation of a line

$x-5y=5\\-5y=5-x\\y=\frac{x-5}{5}\\y=\frac{1}{5}x-1$

Since x can take any value then the equation has infinite solutions. But we need only an solution (x,y). Then, taking x=0 we have that $y=\frac{1}{5}*0-1=-1$ .

Therefore the ordered pair (x,y)=(0,-1) is a solution of the equation.

Sally has two pieces of fabric that are 128 inches long. She needs to cut each piece of fabric into multiple pieces that are 6 i

Alborosie

42 pieces. Add 128+128=256, then divide that by 6 which is 42.6, and you have 42 pieces (complete pieces, but if it doesn’t ask for complete pieces then your answer is 42.6)

Deena is planting two rectangular gardens. One garden is 3.67 feet by 8.56 feet, and the other garden is 3.67 feet by 7.45 feet.

Finger [1]

Answer:

A is the correct expression

Step-by-step explanation:

the formula for area of a rectangle is A=WxL

A=area W=width L=length

8.56x3.67=31.42 area of first garden

7.45x3.67=27.34 area of second garden

hope this helps!

have a great day :)

Given: △DMN, DM=10√3 m∠M=75°, m∠N=45° Find: Perimeter of △DMN

xxTIMURxx [149]

Correct Answer is: Perimeter of ΔDMN is 54.873 units.

Solution:-

Given that DM=10√3,m∠M=75°,m∠N=45°

So,m∠D= 180-(75+45) = 60°

So to find perimeter we need other 2 sides also.

Let us use sine rule to find them.

$\frac{DM}{sin(N)}=\frac{DN}{sin(M)} =\frac{MN}{sin(D)}$

$\frac{10\sqrt{3} }{sin(45)} = \frac{DN}{sin(75)}=\frac{MN}{sin(60)}$

$DN=\frac{10\sqrt{3} }{sin(45)}Xsin(75) = 23.66$

$MN=\frac{10\sqrt{3} }{sin(45)} Xsin(60)=21.213$

Hence perimeter = DM+MN+DN

= 10+21.213+23.66

=54.873 units
