What is the value of the expression x−2y+√4z when x = 12 y = -3 and z = 4
Given expression,
=> x - 2y + √4z
when x = 12 , y = -3 and z = 4 ,=> 12 - 2(-3) + √4*4
=> 12 +6 + 4
=> 18 + 4
=> 22
Answer: 22
Step-by-step explanation: first write out the equation then add in the numbers in place of the variables
Ex: 12-2(-3)+√4(4)
Solve for x
3/5 (x − 7/10)= −3 1/4
Enter your answer as a mixed number in simplest form.
Answer:
x = 11(13/14)
Step-by-step explanation:
3/5(x – 7/10) = -31/4
open the bracket:
3/5 * x – 7/10 = -31/4
3/5 * –7x/10 = -31/4
3/5 + 31/4 = 7x/10
(12+155)/20 = 7x/10
167/20 = 7x/10
cross multiply:
140x = 1670
x =1670/140
x = 11(130/140)
x = 11(13/14)
The value of x is 1/5.
What is 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. LHS = RHS is a common mathematical formula.
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:
3/5 (x − 7/10)= −3 1/4
Now, Solving for x
3/5 ( x- 7/10 )= 13/4
x- 7/10 = -13/4 x 5/3
x- 7/10 = -65 /12
x= -65/12 + 7/10
x= 24/ 120
x= 1/5
hence, the value of x is 1/5.

The owner of a lemonade stand mixes juice that costs 2 dollars per gallon with juice that costs 7 dollars per gallon. She gets 20 gallons of punch that costs 4 dollars per gallon. How much of each juice does she use?
Answer:
8 gallons at $7
12 gallons at $2
Step-by-step explanation:
x gallons at $7 with the remaining (20 - x) gallons at $2 to get 20 gallons at $4
x(7) + (20 - x)(2) = 20(4)
Distribute
7x + 40 - 2x = 80
Combine like terms
5x + 40 = 80
Subtract 40 from both sides
5x = 40
Divide both sides by 5
x = 8 gallons at $7
20 - x = 12 gallons at $2

Answer:
z = -3/2
Step-by-step explanation:
Our goal here is to solve -1/3 (4+z)=-5/6 for z.
Begin by multiplying both sides by 6, to eliminate the fractions:
-2(4 + z) = -5
Isolate (4 + z) by dividing both sides by -2: 4 + z = 5/2
Finally, determine z by subtracting 4 from both sides: z = 5/2 - 8/2 = -3/2
z = -3/2

[tex]\sqrt[3]{488+24} \\[/tex]
Answer:
8
Step-by-step explanation:
First, add the values inside the radical
488+24 = 512
[tex]\sqrt[3]{512}[/tex] = x
This means that: [tex]x^{3}[/tex] = 512
Therefore, x must be equal to 8.
[tex]\sqrt[3]{512}[/tex] = 8
