Answer:
y = -5.5
Step-by-step explanation:
The only lines that have a slope of 0 are horizontal lines. Horizontal lines are always in the form y = c where c is a constant. Basically, on a horizontal line, no matter what x is, y will always be the constant c. Therefore, the x coordinate of our given point does not matter and we only have to look a the y-coordinate, which is -5.5. Therefore, the equation is y = -5.5.
Answer:
1000 runners
Step-by-step explanation:
Take total number of runners to be -----------x
90% of x managed to complete the marathon= 90/100 × x =0.9x
30% of those who completed the marathon were men= 30% × 0.9x
=0.3×0.9x= 0.27x
=270 men completed the marathon; this means
0.27x=270--------------------------------find x by dividing both sides by 0.27
x= 270/0.27
x=1000 runners
6x-9=15
6x=24
x=4
Therefore the answer is A.
Hope this helps :)
Answer:
X=24
Step-by-step explanation:
1. (4x + 11) + (3x + 1) = 180 (Combine like terms)
2. 7x + 12 = 180 (Subtract 12 from both sides)
3. 7x = 168 (Divide both sides by 7)
4. x = 24
