Answer: Algebraic linear expression
Step-by-step explanation:
An algebraic expression in mathematics is an expression built up from integer constants with
unknown variables, and the algebraic operations. For example, 6x² − 2xy + 20 is an algebraic expression which is quadratic in nature.
The general formular for algebraic linear expression is Y - MX - C
Answer:
x = 135°
Step-by-step explanation:
The angle x is the same fraction of 360° that the shaded area is of the area of the circle.
The area of a circle is given by the formula ...
A = πr²
For a radius of 12 cm, the area of the circle is ...
A = π(12 cm)² = 144π cm²
Then the measure of angle x is ...
x = (54π cm²)/(144π cm²)×360°
x = 135°
Answer:
Given:
5 pounds rice cost $2.49
To Find:
Cost of 9 pounds rice
Step-by-step explanation:
5 pounds rice cost $2.49
1 pound rice will cost $ 
So,
9 pounds rice cost = 1 pound rice cost × 9
= $ 
= $0.498 × 9
= $4.482
Answer:
23
Step-by-step explanation:
In this question, we want to evaluate the expression "9z-4" for z=3.
This means, we want to calculate the result when we substitute the z in this expression for 3.
So we have: 9(3)-4, which is equal to 23.
Let me know if this helps!
Answer:
x = 18
Step-by-step explanation:
Since that is a right angle, we know that the total degrees of the angle is 90 degrees.
1) Based off of that, you can form the equation: 3x + 2x = 90.
2) solve the equation for x. Combine like terms: 3x + 2x = 5x.
5x = 90
3) So now, divide both sides by 5. 90 / 5 = 18
x = 18
Therefore, the correct answer is x = 18.
