Answer:

a=4

Step-by-step explanation:

Equation: 2a-6+5a=3a+10

Combine like terms:

2a+5a-3a=4a

4a-6=10

4a=10+6

solve. /algebra

Answer:

a=4

Step-by-step explanation:

Add like terms. You get 7a-6=3a+10. Subtract 3a from 7a and get 4a. Add 6 to both sides and get 16. After this, divide by 4.

Black_prince [1.1K]

Question is Incomplete;Complete question is given below;

Sam wants to fence his rectangular garden plot along its length on the front side. The perimeter of the plot is 24 meters, and its length is 3 times its width. If x is the length and y is the width of the plot, set the equations of the system. Solve and determine the values of x and y. If the cost of fencing is $25 per meter, how much does Sam need to spend on fencing?

Answer:

Length of the plot (x) is 9 meter and width of the plot (y) is 3 meter.

Sam need to spend $225 on fencing.

Step-by-step explanation:

Given;

Perimeter of the plot =24 m

Length of the plot is denoted 'x'

Width of the plot is denoted by 'y'

Cost of Fencing = $25 per meter.

We need to find the the values of x and y.

Also we need to find how much does Sam need to spend on fencing.

Solution:

Now given that;

length is 3 times its width.

so we get;

x=3y

Now we know that;

Perimeter of the rectangle is equal to 2 times sum of its length and width.

framing in equation form we get;

24=2(x+y)

But x=3y

so we get;

24 =2(3y+y)\\\\24=2(4y)\\\\24=8y

Dividing both side by 8 we get;

\frac{24}{8}=\frac{8y}{8}\\\\y =3\ m

Now width of the plot = 3 meter

Length of the plot x=3y=3\times3= 9\ m

Hence Length of the plot (x) is 9 meter and width of the plot (y) is 3 meter.

Now given that;

Sam wants to fence his rectangular garden plot along its length on the front side.

So we can say that;

Length to be fenced = 9 m

Cost of fencing = $25/meter

Cost of fencing the garden = 9\times 25= \$225

Hence Sam need to spend $225 on fencing.

the north bound plane. has traveled 63 kilometers. If the two airplanes are 87 kilometers aprat, how far has the eastbound airpl
WITCHER [35]

The distance travelled by east bound car is 60 km.

<u>Explanation:</u>

Distance travelled by North bound plane = 63 km

Distance travelled by east bound plane = 87 km

Distance travelled by east bound plane = ?

The trajectory of the plane would form a triangle.

In a right angle triangle:

(hypotenuse)² = (base)² + (height)²

(87)² = (b)² + (63)²

7569 = b² + 3969

b² = 3600

b = 60 km

Therefore, distance travelled by east bound car is 60 km.
