Hi there!
We can solve this equation by using the systems of equations.
We can do this by subtracting like terms from both equations using substitution.
First, let's find the value of y:
6x + 3y = 21
3y = -6x + 21
y = -2x + 7
Then, we should plug it into one of the equations:
3x - 7y = 2
3x - 7(-2x + 7) = 2
3x + 14x - 49 = 2
17x = 51
x = 3
Now, we solve for y by plugging the value of x into the equation:
3x - 7y = 2
3(3) - 7y = 2
9 - 7y = 2
-7y = -7
7y = 7
y = 1
There's your answers.
Hope this helps!
Answer: 21.21 meters
Step-by-step explanation:
Hi, to answer this, first we have to calculate the circumference (C) of the wheel:
C = π x diameter
Replacing with the values given:
C = π x 45 = 141.37 cm
Then we multiply it by the number of revolutions:
141.37 x 15 = 2,120.6 cm
Since
1 cm = 0.01 m
2,120.6 x 0.01 = 21.21 meters

Answer:
y= 52/19 or 2 14/19
Step-by-step explanation:
first we open the brackets
16y-28+3y=24
then we shift the terms
16y+3y= 24+28
19y= 52
y= 52/19 or 2 14/19
hope it helps,pls mark me as brainliest
Answer:
The value of C is 3
Step-by-step explanation:
all of the angles of a triangle add up to 180°. first you would add 92 and 46 and get 138. You then subtract 180 and 138 and get 42. then you divide 42 by 14 and get 3. then substitute 3 back into the equation and you get 180.
A(n)=3n+5
You add 3 to each number so it’s the rate
5 is the initial value. 8-3=5
