The sum of three numbers is 164. The second number is 3 more than twice the first number, and the third number is four times the first number. What are the three numbers
Answer:
23, 49, and 92
Step-by-step explanation:
three numbers x, y, z
x+y+z=164
y=2x+3
z=4x
we have three equations and two of them are in terms of x so we can solve for x first by plugging in the two equations to our first equation
x+2x+3+4x=164
7x+3=164
7x=161
x=23
then find y
y=2(23)+3=46+3=49
then find z
z=4(23)=92

Answer:
y=5/2x+13.5
Step-by-step explanation:
5x-2y=10
-2y=-5x+10
y= 5/2x-5
y-6=5/2(x+3)
y-6=5/2x+ 7.5
y=5/2x+13.5
Answer:
Step-by-step explanation:
First you must isolate y in the given equation
5x - 2y = 10 Subtract 5x from both sides
-2y = -5x + 10 Divide both sides by - 2
y = -5/-2 x + 10 / -2
y = 2.5 x - 5 The new equation has a slope of 2.5
x = - 2
y = 6
y = 2.5x + b
6 = 2.5*-2 + b
6 = -5 + b Add 5 to both sides
6+ 5 = b
b = 11
Answer: y = 2.5x + 11

What is the greatest common factor of 64xyz−36xy+24x?
1) Find the Greatest Common Factor (GCF).
4x
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
[tex]4x(\frac{64xyz}{4x} +\frac{-36xy}{4x} +\frac{24x}{4x})[/tex]
3) Simplify each term in parentheses.
[tex]4x(16yz-9y+6)[/tex]
The greatest common factor of equation A = 64xyz - 36xy + 24x is 4x
A = 4x ( 16yz - 9y + 6 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is given by
A = 64xyz - 36xy + 24x
Now , the Greatest Common Divisor is the highest number that divides exactly into two or more numbers. It is also expressed as GCF
So , the equation A can be factorized as
Taking 4x as the common term of the equation , we get
A = 4x ( 16yz - 9y + 6 )
So , the common term is 4x and the greatest common factor of the equation A is 4x
Therefore , the GCF is 4x
Hence , The greatest common factor of equation A = 64xyz - 36xy + 24x is 4x and A = 4x ( 16yz - 9y + 6 )
