<h3>Given:</h3>
▪
First, rewrite the numerator in such a way that the coefficient 2.1 becomes 21:
Divide the coefficient:
Divide the base by subtracting the exponents of the base 10.
Hence, the quotient of the given expression has a coefficient of 3 and the exponent of the base 10 is -4.
Answer:
shouldn't it be 1+1=x(6÷2)
Answer:
1/2
Step-by-step explanation:
slope formula (diff. of y)/(diff. of x);
(1-0)/(2-0) equals to 1/2
Answer:
The answer to your question is x = -2, y = 5 and z = 7
Step-by-step explanation:
Data
first number = x
second number = y
third number = z
Process
1.- Write equations to solve this problem
x + y + z = 10 Equation l
2y - x = 12 Equation ll
x - y + 2z = 7 Equation lll
2.- Solve equation ll for x
x = 2y - 12
3.- Substitute the previous equation in equation l and lll
(2y - 12) + y + z = 10 (2y - 12) - y + 2z = 7
2y - 12 + y + z = 10 2y - 12 - y + 2z = 7
3y + z = 10 + 12 y + 2z = 19
3y + z = 22
4.- Solve for y and z
-2(3y + z = 22)
y + 2z = 19
-6y - 2z = -44
y + 2z = 19
-5y + 0 = -25
y = -25/-5
y = 5
-Find z
5 + 2z = 19
2z = 19 - 5
2z = 14
z = 14/2
z = 7
5.- Find x
x + 5 + 7 = 10
x = 10 - 5 - 7
x = -2
solve for x.
4x−5=7+4y
Add 5 to both sides.
4x−5+5=4y+7+5
4x=4y+12
Divide both sides by 4.
4x/4=4y+12/4
x=y+3
