answer asap
304 is 40% of 760 I hope this helps :)
40% of 760 is 304 :)
The point which lies on Arturo's graph is option c. (1, 20)
Proportional relationships are relationships for which the equations are of the form y = kx, where k is a constant.
Here k is also called constant of proportionality.
Given that,
An elevator moves at a constant speed of 20 feet per second.
Speed = Distance / Time
Speed is constant.
20 = d / t, where d is the distance and t is the time.
d = 20t
When t = 1, d = 20.
(1, 20) lies on the graph of this relationship.
Hence the point (1, 20) lies on the graph of this relationship.

The complete question with the options is given below.
An elevator moves at a constant speed of 20 feet per second. Arturo correctly graphs this proportional relationship on a coordinate plane. Which of the following points lies on Arturo's graph?
(a) (0, 20)
(b) (20, 0)
(c) (1, 20)
(d) (20, 1)
There are total 11 packets of squash seeds and 7 packets of basil seeds.
A system of linear equations (or linear system) is a collection of one or more linear equations involving the same variables.
The substitution method is the algebraic method to solve simultaneous linear equations. In this method, the value of one variable from one equation is substituted in the other equation.
According to the given question.
Cost of one packet of basil seeds = $1.50
Cost of one packet of squash seeds = $2.50
Cost of 18 packets of seeds = 38
Also, b represents the number of packets of basil seeds and s represents of numbers of squash seeds.
Therefore, from the given conditions we get some system of equations
and
From equation (i)
Substitute the value of s in the equation (ii)
⇒
⇒
⇒
⇒
⇒
So,
Hence, there are total 11 packets of squash seeds and 7 packets of basil seeds.

Answer:
Step-by-step explanation:
b+s=18
s=18-b
1.50 b+2.50 s=38
multiply by 4
6.00 b+10.00 s=152
divide by 2
3 b+5 s=76
3 b+5(18-b)=76
3 b+90-5 b=76
-2b=76-90
-2b=-14
divide by -2
b=7
s=18-7=11
