What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
Tony gets paid $5 per hour to babysit his cousin.
This weekend, he babysat on both Saturday and Sunday.
He made a total of $55.
Tony babysat for 6 hours on Sunday.
Let the number of hours be x on Saturday.
Then we have the equation that will be
x × 5 + 6 × 5 = 55
5x + 30 = 55
5x = 25
x = 5

The length of a rectangular field is 10m more than its breadth. If the
perimeter is 80m, find its length and breadth.
Answer:
length = 15
breadth = 25
Step-by-step explanation:
length = breadth + 10
let length be x
length = x
breadth = x + 10
perimeter = 2(length) + 2(breadth)
80 = 2(x) + 2(x + 10)
80 = 2x + 2x + 20
80 = 4x + 20
80 - 20 = 4x
60 = 4x
15 = x
length = x = 15
breadth = x + 10 = 25

For the high jump, each competitor receives multiple opportunities to clear the bar at each height. On average, Shane completes 2 out of 3 jumps on the lowest bar, 4 out of 6 jumps on the middle bar, and 1 out of 4 jumps on the highest bar. Write an equation that you could use to find Shane’s overall average number of jumps completed. Calculate Shane’s average using the equation. (2 points)
Average number of jumps on lowest bar = 3/2 = 1.5
Average number of jumps on middle bar = 6/4 = 1.5
Average number of jumps on highest bar = 4/1 = 4
Overall average number of jumps = 3/2 + 6/4 + 4/1 = 7
Overall average number of jumps =
+ 1/probability of complete the lowest bar
+1/probability of complete the middle bar
+ 1/probability of complete the highest bar
Equations of Shane’s overall average number of jumps completed = x * (7/13), where x is the total number of overall jumps.

Answer: 19/36
Step-by-step explanation:
A mean equation is hidden in this word problem. Focus on the 2 out of 3, 4 out of 6, and 1 out of 4. Those numbers are actually fractions. Shane managed to complete 2/3 of the jumps on the lowest bar, he managed to complete 4/6 of the jumps on the middle bar, and 1/4 of the jumps on the highest bar.
Step 1: Write the mean equation
(2/3 + 4/6 + 1/4)/3 = x
Step 2: Find the common denominator
3, 6, and 4 are all factors of 12, so 12 is your common denominator
4(2/3) = 8/12
2(4/6) = 8/12
3(1/4) = 3/12
Now rewrite the equation with the common denominator
(8/12 + 8/12 + 3/12)/3 = x
Step 3: Sum the fractions
(19/12)/3 = x
Step 4: I
Invert and multiply
(19/12)/3 = 19/12 * 1/3 = 19/36
This is the answer

Step-by-step explanation:
Find the zeros of the function f(x)=x^2-2x-3 to the nearest hundredth.
Answer:
x=3, x=-1
Step-by-step explanation:
Finding zeros of a function means plugging in 0 for f(x).
You'll get 0=x^2-2x-3.
Then solve by plugging in equation into quadratic formula: -b±√b^2-4ac/2a
Simplify and you'll get x=3, x=-1.

Given the figure above, determine
Answer:
122
Step-by-step explanation:
Angle W + Angle A = 180
This is because it's supplementary (adds to 180)
Angle W= 127
180-127=53
Angle A= 53
Angle B= 69
All angles in triangle (get it, tri angle?) add to 180
If we know that any 2 angles we can figure out the 3rd
so 53+69= 122
Triangle sum 180 = 180 - 122
= 58
Angle C = 58
Angle C + Angle X = 180 (B/c it's on a straight line which is = to supplementary angles
Angle X = 180 - Angle C
= 180 - 58
= 122
