A = 210 + 20(h - 7) <== ur equation
if she earns 410 tutoring...
410 = 210 + 20(h - 7)
410 = 210 + 20h - 140
410 = 20h + 70
410 - 70 = 20h
340 = 20h
340/20 = h
17 = h <=== she spent 17 hrs tutoring
Answer:
-1
Step-by-step explanation:
"Gradient" is yet another term for "slope" or "rate of change." It is the ratio of "rise" to "run."
Here, the graph goes through grid intersections such that 1 to the right is 1 down. The "rise" is -1 for a "run" of 1, and the slop (gradient) is ...
m = rise/run = -1/1 = -1
The gradient of the graphed line is -1.
Answer:
92
Step-by-step explanation:
Let the number be x.
As per the question,
3/4x - 18 = 1/2x + 5
(4)3/4x - (4)18 = (4)1/2x + (4)5
3x - 72 = 2x + 20
x = 92
The number is 92.
Answer:
Yes: (3,4,5)
Step-by-step explanation:
10² = 6² + 8²
(10/2)² = (6/2)² + (8/2)²
5² = 3² + 4²
25 = 9 + 16
25 = 25
The sides satisfy the pythagoras theorem
10 is the hypotenuse, 6 & 8 are the legs
5 is the hypotenuse, 3 & 4 are the legs
