Answer:
1st Q: C. Algebraic Expression; it consists of numbers and a variable.
2nd Q: D. The number of times Chris washes the car.
Step-by-step explanation:
1st Question:
Numerical Expression: Contains numbers and operations. Numerical expressions are your typical 2 + 2 equations. The ones you start learning in Kindergarten with just numbers and different operations such as addition, subtraction, division, and multiplication.
EX: 108 - 24 = ?
? = 84
Algebraic Expression: Contains numbers, operations, and variables. They are the same as normal, numerical expressions with the exception that it also has letters, or variables.
EX: 2x + 3 = 7
x = 2
__________________________________
2nd Question:
Amount Chris earns per wash: $10.00
# of times Chris washes the car: x
So 10x means what...?
10 = earns per wash
x = times washed the car
Multiply 10 by x to find the total Chris earns for the number of times he washes the car, x.
(Just as a reference, this would be counted as an Algebraic Expression).
Hope this helps! :)

- 6x < 24
solve for x and what’s the solution?
Answers
Answer:
x > -4
Step-by-step explanation:
In order to get x by itself, you divide -6 on both sides. So, -6x divided by -6 = x and 24 divided by -6 equals -4.
However, the answer is not x < -4 because a rule of inequalities states that any time you divide or multiply both sides of an inequality by a negative number, the inequality sign is flipped. So, the answer is x > -4
Answer:
x > -4
Step-by-step explanation:
- 6x < 24
Divide each side by -6, remembering to flip the inequality
-6x/-6 > 24/-6
x > -4
A box has a length of 30 inches, a width of 40 inches, and a height of 120 inches. Can a cylindrical rod with a length of 342.9 centimeters fit in the box?
Answers
Answer: 6 inches = 15.24 cm length
8 inches = 20.32 cm width
24 inches = 60.96 cm height
The diagonal along the side of the box = 20.32^2 + 60.96^2 = 4,129.024
square root (4,129.024) = 64.257 so the rod will fit diagonally.

Answers
Answer:
$580000
Step-by-step explanation:
To find decrease we simply reverse the operations of increase
increase is x x 1.05 = 609000
x = 609000 / 1.05 = 580000 initial value
x= $580000
proof
580000 x 1.05 = 609000 new value

The diameter of a circle is 2 centimeters. What is the area?
d=2 cm
Answers
Answer: 4π cm or 12.56 cm
Step-by-step explanation: To find the circumference of this circle, start with the formula for the circumference of a circle which is C = 2πr.
Since the radius is 2 centimeters, we can
plug in 2 centimeters for r in the formula.
So we have (2)(π)(2 cm) which is equal to 4π cm.
So the circumference of this circle is 4π cm.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.
So we have (4)(3.14) which is equal to 12.56.
So the circumference of the circle is
approximately equal to 12.56 cm.

Therefore, the correct answer is: < b = 73°
