Step-by-step explanation:
-5.9x - 3.7y = -2.1
5.9x + 3.7y = 2.1
If we add these two equations together, -5.9x cancels out 5.9x, -3.7y cancels out 3.7y, and -2.1 cancels out 2.1.
This leaves us with:
0 = 0
Since this is true, that means there are infinite solutions.

Answer:
99 square units
Step-by-step explanation:
The scale factor works for linear dimensions like length, width, and perimeter. For a scale factor of k, area changes by k^2.
Here you have a scale factor of 3, so the4 area increases by a scale factor of 3^2 which is 9.
original area = 11 square units
scaled area = 9 * 11 square units = 99 square units

The equation d=11t models the distance a mouse can travel when it runs at top speed. In the equation,d is the distance in feet and t is the time in second. Complete the table WILL GIVE BRAINLIEST FOR CORRECT ANSWER
Answers
Answer:
t = 0 , d = 0
t = 2, d = 22
t= 4, d = 44
t = 6, d = 66
Step-by-step explanation:
Here, given the equation that relates the time in seconds to the distance in feet, we want to complete the given table
From the equation, we have that d = 11t
This mean that by multiplying the time by 11, we get the distance
Thus, we have that ;
when t = 0
d = 11 * 0 = 0
when t = 2
d = 11 * 2 = 22 ft
when t = 4
d = 11 * 4 = 44 ft
when t = 6
d = 11 * 6 = 66 ft
Given the equation that models the proportional relationship, the missing values in the table are: 0, 22, 44, and 66.
Equation of a Proportional RelationshipEquation that models a proportional relationship between two variables, "t" and "d" can be expressed as: d = kt.k is the constant of proportionality.Given:
d = 11t
Find the corresponding values of d by plugging in the given values of t:
When t = 0,
d = 11(0) = 0
When t = 2,
d = 11(2) = 22
When t = 4,
d = 11(4) = 44
When t = 6,
d = 11(4) = 66.
Therefore, given the equation that models the proportional relationship, the missing values in the table are: 0, 22, 44, and 66.

If a 5-foot man casts a 6-foot shadow, how tall is a tree that casts a
24-foot shadow?
Answers
Answer:
28.8 foot shadow
Step-by-step explanation:
to do that, you would have to make proportionate fractions. That would mean that you do 5/6 = 24/x. Then you would just cross multiply to get 5x = 144. Then you would divide to isolate x. That would give you 28.8
Manny makes dinner using 1 box of pasta and 1 jar of sauce. If pasta is sold in packages of 10 boxes and sauce is sold in packages of 2 jars, what is the least number of dinners that Manny can make without any supplies leftover?
Answers
Answer:
10 dinners
Step-by-step explanation:
We solve using the Least Common Multiple Method.
We are told:
Pasta is sold in packages of 10 boxes Sauce is sold in packages of 2 jars.
We find the Multiples of 2 and 10
Multiples of 2:
2, 4, 6, 8, 10, 12, 14
Multiples of 10:
10, 20, 30
Therefore,
LCM(2, 10) = 10
The least number of dinners that Manny can make without any supplies leftover is 10 dinners
