ANSWER
EXPLANATION
The given line is
This is a linear equation in two variables.
There are infinitely many solutions.
Let us solve for y.
Let
Then
The group of ordered pairs which are on the given line are represented by:
Where t is real number.
Anwer:
4b/a=2
Step-by-step explanation:
Lets assume:
a = 4 & b = 2
So a/b would equal 2.
4b/a indicates that you are going to multiply b times 4, meaning that in this scenario you would multiply 2 times 4.
4(2) = 8
and 8 divided by (4) is 2.
Why 4? Because remember a = 4 (in this scenario).
Other examples:
10/5 = 2, --> 4(5) = 20, --> 20/10 = 2.
20/10 = 2. --> 4(10) = 40, --> 40/20 = 2.
Answer:
a, b, and c can be formed a triangle
The area of the triangle is 13385.87 square units.
Step-by-step explanation:
<em>Let us revise an important fact in any triangle</em>
- The sum of the lengths of the two shortest side must be greater than the length of the longest side
The length of the sides are a = 240, b = 132, and c = 330
∵ The two shortest sides are a = 240 and b = 132
∵ a + b = 240 + 132 = 372
∵ The longest side is c = 330
∵ 372 > 330
∴ a + b > c
∴ a, b, and c can be formed a triangle
<em>Let us revise the </em><em>Heron's formula</em><em> of the area of the triangle</em>
- Area = , where a, b,c are the lengths of the sides of the triangle, and
∵
∴
∴
∴
The area of the triangle is 13385.87 square units.

It took six hours longer to go there than it did to come back.
The average speed on the trip there was 152 mph.
The </span></span><span>average speed on the way back was 380 mph.
How many hours did the trip there take?
(x + 6)152 = 380x
228x = 912
x = 4
The trip there took 10 hours.</span>
