Answer:
40kg
20kg
10kg
Step-by-step explanation:
The computation of the food each one is getting as follows
Total weights of all dogs
= 20 kg + 10 kg + 5kg
= 35 kg
And, the food is 70 kg
So, each one is getting
for 20 kg
= 70 ÷ 35 × 20
= 40 kg
For 10 kg
= 70 ÷ 35 × 10
= 20 kg
And, for 5 kg
= 70 ÷ 35 × 5
= 10 kg
The third term in an arithmetic sequence is 9 and the fifth term is 21 . If the first term if a1, which is an equation for the nth term of this sequence?
A:an=6n-9
B:an=14n+6
C:an=6n+14
D:an=9n-6
Answer:
A: an = 6n - 9
Step-by-step explanation:
third term in an arithmetic sequence is 9
a3 = a + 2d
a + 2d = 9
the fifth term is 21
a5 = a + 4d
a + 4d = 21
a + 2d = 9 (1)
a + 4d = 21 (2)
Subtract (1) from (2) to eliminate a
4d - 2d = 21 - 9
2d = 12
d = 12/2
d = 6
Substitute d = 6 into (1)
a + 2d = 9 (1)
a + 2(6) = 9
a + 12 = 9
a = 9 - 12
a = -3
nth term of this sequence = a + (n - 1)d
= -3 + (n - 1)6
= -3 + 6n - 6
= 6n - 9
an = 6n - 9

Solve by Elimination:
x - 2y = 4
X - 1y = 2
its urgent
Answer:
x = 0 and y = -2
Step-by-step explanation:
x - 2y = 4 and X - 1y = 2
you mentioned elemination aka substraction
so you when substract x - x = 0 -2y -( -y) = -y and 4 -2 = 2
so - y = 2
or y = 2
now substitute the numbers
x + 4 = 4
x = 0
and try it with one of the equation or sometimes trying on both of them can be very helpful

3. A sprinkler rotates 75°, pauses, and then rotates another 75°, How many degrees did it rotate altogether?
0 degrees
140 degrees
150 degrees
160 degrees
Help?
Answer: 150 degrees
Step-by-step explanation:
The number of degrees did it rotate altogether should be considered as the 150 degrees.
Calculation of the number of degrees:Since A sprinkler rotates 75°, pauses, and then rotates another 75
So, here total degrees be like
= 75 degrees + 75 degrees
= 150 degrees
hence, The number of degrees did it rotate altogether should be considered as the 150 degrees.

What division problem can be represented using the number line?
Melvin is pushing a tire during workout with the dimensions shown how many square inches of space has a tire covered after Melvin pushes the tire 5 times around
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but I would show you how to solve it.
Solution:
A circle is the locus of a point such that its distance from a fixed point which is its center is always constant.
The tire has the shape of a circle. Therefore the distance the tire covers if it is pushed around once is the same as the circumference of the tire. The circumference is given by:
Circumference = 2πr; where r is the radius of the tire
Let us assume that the tire has a radius of 7 cm. Hence:
Circumference = 2π(7) = 44 cm
If the tire moves around 5 times, the distance covered = 5 * circumference of tire = 5 * 44 cm = 220 cm

Carlos and Lily want to know the combined amount of money they made last week. They both made $12 per hour, but Carlos also made a $35 bonus. Carlos says the combined amount is 12C + 35 + 120 where Cis the number of hours he worked, and L is the number of hours Lily worked. Lily says the combined amount is 12(C+ L) + 35. Who is right? Explain.
Answer:
Lily is rightStep-by-step explanation:
Carlos made:
12C + 35Lily made:
12LTogether they made:
12C + 35 + 12L = 12(C + L) + 35Lily is right. We don't know what 120 means in Carlos's equation, he should put 12L for Lily.

3. Which of the following equations would not have a solution that is the same as the solution to the system
shown below
2x + 3y = 1. x-y=5
(1) 3x+2y=6
(3) 5y=-9
(4) 2x-2y=5
(2) 4x+6y=2
Answer:
A
Step-by-step explanation:
The solution that is not the same as the solutions to the system of equations is 2x - 2y = 5.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
2x + 3y = 1 _____(1)
x - y = 5 _______(2)
From (1) and (2) we get,
x = 5 + y
2 (5 + y) + 3y = 1
10 + 2y + 3y = 1
10 + 5y = 1
5y = -9
y = -9/5
Now,
x = 5 - 9/5
x = (25 - 9)/5
x = 16/5
The solutions are x = 16/5 and y = -9/5.
Now,
(1) 3x + 2y=6
3 x (16/5) + 2 x (-9/5) = 6
48/5 - 18/5 = 6
30/5 = 6
6 = 6
(2) 5y = -9
5 x (-9/5) = -9
-9 = -9
(3) 2x - 2y = 5
2 x (16/5) - 2 x (-9/5) = 5
32/5 + 18/5 = 5
50/5 = 5
10 ≠ 5
(4) 4x + 6y = 2
4 x (16/5) + 6 x (-9/5) = 2
64/5 - 54/5 = 2
10/5 = 2
2 = 2
Thus,
3x+2y=6, 5y=-9, and 4x+6y=2 have the same solutions.

Step-by-step explanation:
1A. Nayeli wants to earn some extra money so she sells lemonade for $2 per cup and orange juice for $3 per cup. She sells a total of 100 cups and earns $240. Later she wants to find the number of cups of lemonade and the number of cups of orange juice she sold. Which system of equations below represents this situation?
1. 2x + 3y = 240 AND x + y = 100
2. 2x + 3y = 100 AND x + y = 240
3. x + 2y = 100 AND 3x + y = 240
4. 2x + 100 = 240.AND x = 3y
1B. In the context of the problem, what does your solution (x,y) mean? Fill in the blanks for the solution sentence below: Nayeli sold ____ cups of lemonade and ____ cups of orange juice. Write your answer in this form: 20, 40
Answer:
1. 2x + 3y = 240 AND x + y = 100
Nayeli sold 60 cups of lemonade and 40 cups of orange juice.
Step-by-step explanation:
Let
Number of cups of lemonade sold = x
Number of cups of orange juice sold = y
The system of equation could be represented by:
2x + 3y = 240 (1)
x + y = 100 (2)
from (2)
x = 100 - y
Substitute into (1)
2x + 3y = 240 (1)
2(100 - y) + 3y = 240
200 - 2y + 3y = 240
- 2y + 3y = 240 - 200
y = 40 cups
Substitute y = 40 into (2)
x + y = 100 (2)
x + 40 = 100
x = 100 - 40
x = 60 cups
Nayeli sold 60 cups of lemonade and 40 cups of orange juice.
(x, y) = (60, 40)
