In a drill, Mark gives Fred a 45 meter head start. After t seconds, Fred is a distance 5t +45 from the starting line andMark is a distance of 6t from the starting line. How far ahead of Mark is Fred after t seconds?
Answers
Answer: After t seconds, Fred is far away from Mark by (45-t).
Step-by-step explanation:
Given: Mark gives Fred a 45meter head start.
After t seconds, the distance of Fred from the starting point = 5t+45
The distance of Mark from the starting point = 6t
Now, Distance between Fred and Mark after t seconds = Location of Fred - Location of Mark
= (5t+45)-6t
= 5t+45-6t
= 45-t
Hence, After t seconds, Fred is far away from Mark by (45-t).

a farmer was on his tractor and drove by some chickens and pigs in his field he counted 30 heads and 84 legs
*REUPLOAD* PLEASE ANSWER W EXPLANATION
Answers
Answer:
There are 18 pigs and 12 chickens.
Step-by-step explanation:
p = # of pigs
c = # of chickens
I'm assuming each animal has one head and all the pigs have 4 legs and all the chickens have 2 legs, therefore:
p+c = 30
4p+2c = 84
Elimination:
-2(p+c = 30) -2p -2c = -60
4p +2c = 84 4p +2c = 84
2p = 24
p = 12
Now substitute p for 12:
12 + c = 30
c = 18
Check:
4(12) + 2(18) = 84
48 + 36 = 84
84 = 84
There are 18 chickens and 12 pigs.

y = 2x - 8

What is X and Y
Answers
Answer:
x = 5
y = 2
Step-by-step explanation:
In this question, you will have to use one of the equations to find the value of x in terms of y and substitute it in the other equation or vice versa.
y = 2x - 8
x - y = 3
Use the second equation to find the value of x in terms of y.
x - y = 3
x = y + 3
Now that we found that, we can substitute it in the other equation.
y = 2 (y + 3) - 8
y = 2y + 6 -8
y = 2y -2
y + 2 = 2y
y = 2
Now that we got y we can substitute the value in any of the equations to find x.
x - 2 = 3
x = 5
x-y=3
x=y+3
y=2x-8
y=2(y+3)-8
y=2y+6-8
-y=-2
y=2
Plug this back into the second equation to solve for x:
x-y=3
x-2=3
x=5
So x=5 and y=2 is the answer.

What is the value of the expression?
2 x[(-6 + 4) X (5 + 9) - 3]
Answers
Answer:
- 62
Step-by-step explanation:
Calculate the sums within the brackets first and then multiplication, as stated by the BOMDAS rule.
B = Brackets
O = ?
M = Multiplication
D = Division
A = Addition
S = Substitution
(- 6 + 4) = -2
(5 + 9) = 14
- 2 × 14 = -28
- 28 - 3 = - 31
2 × - 31 = - 62

Which values of m and b will create a system of equations with no solution? Select two options. y = mx + b y = –2x + A
Answers
Answer:
(I can not see the options, so I will answer in a general way)
When we have a system of linear equations:
y = a*x + b
y = c*x + d
We have 3 possible options:
One solution: This happens when the lines intersect only one time, and the solution of the system is the point where the lines intersect.
No solutions: This happens when the lines do not intersect, is the case for parallel lines (lines with the same slope but different y-intercept)
Infinite solutions: This happens when the lines do intersect at infinite points, is the case for two equal lines (so both equations represent the same line)
Now we have the system:
y = m*x + b
y = -2*x + A
We want to find values of m and b, such that this system has no solutions.
Then we know that the lines must be parallel, again, the lines must have the same slope but different y-intercept.
Then we can use:
m = -2, b = A + 1
we will get:
y = -2*x + (A + 1)
y = -2*x + A
This system has no solutions.
Other pair can be:
m = -2, b = A + 3
we will get
y = -2*x + (A + 3)
y = -2*x + A
This system has no solutions.
Does the number line below represent the solution to the inequality x > -2?
