what does it mean for a ordered pair to be a solution to a linear equation
Answer:
What's a Solution to a System of Linear Equations? Note: If you have a system of equations that contains two equations with the same two unknown variables, then the solution to that system is the ordered pair that makes both equations true at the same time.

Jordan wrote the equation for a linear relationship as y = -8x - 4. For what value of x is y equal to -20? *
Answer:
2
Step-by-step explanation:
y=-20
-20=-8x-4
-16=-8x
x=2
Answer:
x = 2
Step-by-step explanation:
Given
y = - 8x - 4 ← let y = - 20 in the equation
- 20 = - 8x - 4 ( add 4 to both sides )
- 16 = - 8x ( divide both sides by - 8 )
2 = x

2. Which of the following represents the relationship between the circumference, C, and diameter, d, of any circle?
Answer:
The ratio of the circumference of a circle to the diameter of that circle is the value pi (22/7)
Step-by-step explanation:
Mathematically,
the circumference of a circle is by the formula;
C = 2 * pi * r
Now, as we know, 2r is d where r is the radius of the circle and d is the diameter of the circle
that means;
C = pi * d
hence;
C/d = pi
So the ratio of the circumference of any circle to the diameter is the value called pi
What is the solution to the equation 2x+4 - 12 = 20?
O X=0
O X=1
O X= 2
O X=9
Answer:
x = 14
Step-by-step explanation:
2x+4 - 12 = 20
2x - 8 = 20
2x = 28
x = 14
The solution is, x = 14, is the solution to the equation 2x+4 - 12 = 20.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
given that,
the equation is , 2x+4 - 12 = 20
now, we have to solve it for x
so, for solving the equation,
we isolate the numbers & the variables, then, calculating,
we get,
2x+4 - 12 = 20
2x - 8 = 20
2x = 28
x = 14
Hence, The solution is, x = 14, is the solution to the equation 2x+4 - 12 = 20.

The sum of two numbers is 55. Twice the lesser number is 5 more than the greater number. Find both numbers.
Answer:
x = 20 and y = 35
Step-by-step explanation:
So let's say that the two numbers are represented by x and y.
Firstly, the sum of the two is 55, so:
x + y = 55
Secondly, twice the lesser number is 5 more than the greater number, so, assuming x is lesser:
2x = y + 5
Let's isolate y in the second equation:
y = 2x - 5
We can substitute this into the first equation:
x + (2x - 5) = 55
Now we solve for x:
3x - 5 = 55
3x = 60
x = 20
Now that we know what x is, let's substitute that into the first equation and solve for y:
(20) + y = 55
y = 35
Therefore, x = 20 and y = 35
Hope this helps!

4. Determine the circumference of a circle with a radius that is 14.2 yds. Use 3.14 for π. Round to the nearest tenth.
Answer:
The circumference would be around 90 yards.
Step-by-step explanation:
C = 2πr
r = 14.2
14.2 × 3.14 = 44.588
44.588 × 2 = 89.176
89.176 ≈ 90
C = 90

A basket contains 1/3 as many apples oranges and 3/4 as many oranges and pears there are 64 pairs what is the ratio of the number of Apples to the total of the number of fruit in the basket
Answer:
a=# of apples
3/8(a)=# of oranges
p=# of pears
3/4(p)=# of oranges
(3/8)a=(3/4)p
(3/8)/(3/4)=p/a
(3/8)(6/8)=p/a
3/6=p/a
1/2=p/a
the ratios of pears to apples is 1 to 2
for every 1 pear there are 2 apples
if there are 4 pears there are 8 apples
there are 8 apples
(3/8)(8)=3 oranges
there are 4 pears
(3/4)(4)=3 oranges again
8 apples, 3 oranges, 4 pears
15 pieces of fruit and 3 are oranges
ratio is 3/15=1/5
