(2x-2y)/(36-3x)

So now you sub in the variable into the equation
(* means multiply in this case because x would make it more confusing)

((2*7)-(2*2))/(36-(3*7))
= (14-4)/(36-21)
= 10/15
then you can reduce the fraction to 2/3
so the answer is 2/3 or if you want to put it in a decimal, 0.67

A contractor needs to buy grass seed to cover a lawn. The dimension of the llama song below. One bag of grass seed cover isn’t i
DedPeter [7]

The minimum number of bags of seed the contractor needs to buy the to cover the entire lawn is 4

<h3>How to determine the number of bags</h3>

Start by calculating the area of the entire field using:

Area = Length * Width --- area of square

So, we have:

Area = (18 + 54 + 18)* 28

Area = 2520

Next calculate the area of the porch using:

Area = 0.5 * (L1 + L2) * H -- area of trapezium

So, we have:

Area = 0.5 * (54+ (54 + 18 + 18 - 14 - 14)) * 10

Area = 580

The difference between the areas of the entire field and porch is the area of the lawn.

So, we have:

Lawn= 2520 - 580

Lawn= 1940

The above means that, the area of the lawn is 1940 square yards

If one bag of grass covers 600 square yards, then the number of bags that can cover 1940 square yards is:

n =\frac{1940}{600}

n =3.23

Round to the next highest integer

n =4

Hence, the minimum number of bags of seed is 4 bags

Look at the steps used when solving 3(x - 2) = 3 for X.
Setler [38]

Answer:

3×-6=3

3×=3+6

3×=9

×=3

Step-by-step explanation:

multiply 3 by the variables in the bracket.

then you will get 3×-6=3.

take the -6 to the right hand side and it becomes+6

then you get 3×=3+6 therefore =3×=9

then divide both sides by 3.

3×÷3 and 9÷3

×=3

Triangle ABC is similar to triangle DEF. If angle A measures 28 degrees and angle B measures 74 degrees. If angle F is the large
MakcuM [25]

Answer: 78 degrees

Step-by-step explanation:

Since the angles of a triangle have to add up to 180 degrees, and angle A is 28 degrees, and angle B is 74 degrees, angle C would have to be 78 degrees so there are a total of 180 degrees in the triangle. Since triangle ABC is similar to triangle DEF, the angle measurements of that triangle would also have to be 28 degrees, 74 degrees, and 78 degrees, corresponding to angles D, E, and F. Since the largest of these numbers is 78 degrees, and angle F is the largest angle of the triangle, that would be your answer.

Hope this helps!
