Answer:
82
Step-by-step explanation:
Given
6x - 2y ← substitute x = 16 and y = 7 into the expression
= 6(16) - 2(7)
= 96 - 14
= 82

Hello,
Let's assume t the time for counting one step
V the girl velocity in t
v the escalator velocity in t
d the length to go upstairs
going up: V*60+v*60=d
walking down: V*90-v*90=d
so
V+v=d/60
V-v=d/90
2V=d*5/180
V=d*5/360
V=d/72
V*72=d The girl must count to 72 steps.(here v=0)
Answer:
The system is composed of these two inequalities combined
y <= -x+4
y >= (1/3)x
-----------------------------------------------------------------------
Explanation:
The solid line has the boundary equation y = -x+4
This line goes through (0,4) and (4,0). Using the slope formula, we find that m = -1. Plugging m = -1 and (x,y) = (0,4) into y = mx+b leads to y = -x+4
The shading is below the solid line so we change the equal sign to a "less than or equal to" sign, which leads us to y <= -x+4
That takes care of the first inequality. We must use "or equal to" as part of the inequality to ensure the boundary is solid
------------
The second inequality is y > (1/3)x as the boundary line is y = (1/3)x. This line goes through (0,0) and (3,1). The slope is 1/3 and y intercept is 0
The boundary is a dashed line. This means we don't have "or equal to" as part of the inequality
Answer:
18:5???
Step-by-step explanation:
1 1/2hrs = 90 mins
90 / 5 = 18
25 / 5 = 5
I'd say: 18 : 5??
