Answer:
1st Q: C. Algebraic Expression; it consists of numbers and a <u>variable</u>.
2nd Q: D. The number of times Chris washes the car.
Step-by-step explanation:
<u>1st Question: </u>
<u>Numerical Expression:</u> 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
<u>Algebraic Expression:</u> Contains numbers, operations, and <u>variables</u>. They are the same as normal, numerical expressions with the exception that it also has letters, or variables.
EX: 2x + 3 = 7
x = 2
__________________________________
<u>2nd Question: </u>
Amount Chris earns per wash: $10.00
# of times Chris washes the car: x
<u>So 10x means what...?</u>
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! :)
(Lmk if you don't understand the explanation for the 2nd Q)
17-10= j i really don't know i just guessed
