R-9s=2 add 9s to both sides
r=2+9s making 3r-3s=-10 become:
3(2+9s)-3s=-10 perform indicated multiplication on left side
6+27s-3s=-10 combine like terms on left side
6+24s=-10 subtract 6 from both sides
24s=-16 divide both sides by 24
s=-16/24
s=-2/3, making r-9s=2 become:
r-9(-2/3)=2 perform indicated multiplication on left side
r+6=2 subtract 6 from both sides
r=-4
So s= -2/3 and r= -4
Answer:
if 8 loaves of bread costs $44.00 then 12 loaves will cost $66.00.
Step-by-step explanation:
you divide $44.00 by 8 which will give you $5.05 then you multiply $5.05 by 12.
Answer:
Step-by-step explanation:
The vertical motion of the object is defined by using the height function h(t) such that :
h(t) = -16t² + vt + s , where t is the time instant , v is the initial velocity and s is the initial height of the object.
Now, the height of the bridge = 200 feet
So it would be the initial height ⇒ s = 200
Initially the speed is 0 because the body is in rest at time instant 0 sec.
Hence, the resultant equation is : h(t) = -16t² + 200
And the graph is attached below :
Either one of those angles can be 90 degrees if ABC is a right triangle.
