Answer:
32 daffodils bulbs and 28 crocus bulbs
Step-by-step explanation:
Assuming 'x' as Crocus and 'y' as daffodil. Now we'll form equations.
-> for 60 small flowering bulbs
x+y=60
x=60-y --->eq(1)
->Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.65 each with the budget $27.80
0.25x + 0.65y = 27.80 -->eq(2)
Next is to substitute x=60-y in eq(2)
(2)=>0.25(60-y) + 0.65y = 27.80
15 - 0.25y + 0.65y = 27.80
0.4y = 12.8
y = 12.8/ 0.4
y= 32 daffodil bulbs
Now, plugging the value of y in eq(1)
(1)=>x=60-32
x= 28
x=28 crocus bulbs
Therefore, you can buy 32 daffodils bulbs and 28 crocus bulbs
Basically find the eqatuions of the lines that produce the shaded reigon
so find the lines first
we notice taht they must be inequalities
the upward line is dotted so it must have > or <
ok, hum the slope seems to be -3
the y intercept is 1 so the euaiton is y_-3x+1
the blank is the inequality
ok, test a point
(0,0) is in it
0_-3(0)+1
0_1
0<1
so it is y<-3x+1
secondn line
solid line so ≤ or ≥
slope of 2
y intercept of -1
y_2x-1
(0,0) is a possible solution
test it
0_2(0)-1
0_-1
0≥-1
so the equations are
y<-3x+1 and y≥2x-1
a. the system is y<-3x+1 and y≥2x-1
b. a solution is (0,0) because it is in the shades reigon which is the intersection of the 2 inequalities
Answer:
2,200 students
Step-by-step explanation:
To find the number of students, create a proportion which is two equal ratios. Since the middle school and the high school are proportional then they have equal ratios.
Solve for x by cross multiplying by multiplying the numerator and denominator of each fraction.
900(110) = 45(x)
99,000=45x
2,200 = x
