Example (not a very likely example, however):
At 11 pm the temperature is -15 degrees F, and it continues to drop by 10 degrees F every hour.
Answer:
-162
Step-by-step explanation:
23=5-2/3d
2/3d=-18
d= -27
6d= 6* -27
6d= -162
B=blue
g=green
r=red
2 times as many blue as green
b=2g
3 times as many red as blue
r=3b
subsitute 2g for b
r=3(2g)=6g
r=6g
r+g+b=765
so we subsitute
r=6g
g=g
b=2g
6g+g+2g=765
add like terms
9g=765
divide both sides by 9
g=85
subsitute
b=2b
b=2(85)
b=170
170 blue
Answer:
Step-by-step explanation:
If the equation of height of a man is modeled by the function y = 1.6x + 48 where;
y is the height of a man
x is the shoe size
To get the approximate shoe size for a man having a height of 60 inches, we will substitute y = 60 into the formula ans solve for x as shoen;
y = 1.6x + 48
60 = 1.6x + 48
1.6x = 60-48
1.6x = 12
x = 60/1.6
x = 7.5
x = 7 1/2
Hence the approximate shoe size for a man having a height of 60 inches is 7 1/2
