The equation for the snow in the lawn after t hours and melting at a rate of 0.75 inches per hour will be equal to S = x - 0.75(t).
Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the given information in the question,
Let the initial amount of snow in the lawn is x inches.
Rate of melting of snow per hour = 0.75 inches per hour.
The equation for t hours, after melting of ice,
S = x - 0.75(t)
Here, t is the time in hours and x is the initial amount of ice in the lawn.

Elena jogged 1 mile more than Marcus. Use a graph
to find the number of miles each person jogged.
Answer:Marcus jogged 7 miles while Elena jogged 8 miles.
Step-by-step explanation:
x + (x+1) = 15
2x+1=15
putting like terms together we get:
2x=15-1
2x=14
hence
x=14/2 = 7miles
therefore we conclude that Marcus jogged 7 miles while Elena jogged 8 miles.
2. A ≤ -3 and a ≥ 3
3. a ≥ -3 or a ≤ 3
4. A ≤ -3 or a ≥ 3
This question is worth 40 points. Please help im struggling with this answer!
Answer:
1. a ≥ -3 and a ≤ 3
I am assuming you mean to have an = sign as well
Step-by-step explanation:
|a| < =3
we get two solutions, one positive and one negative
remember to flip the inequality for the negative
a<=3 and a >= -3
Explanation: Algebraic expression is a mathematical expression that consists of variables, numbers, and operations.
8: ← Variable
(x): ← Operation
5: ← Constant
Example: x+12
The variable in the expression is x.
The operation in the expression is +.
The constant in the expression is 12.
Hope this helps!
Thanks!
Have a great day!
Answer:
-x/3+2=y
Step-by-step explanation:
m should be -1/3
mx+n=y
-x/3+n=y
(-9,5) should equalize the equation
3+n=5
n=2
SO -x/3+2=y
A. $22,032
B. $76,500
C. $25,684
O D. $28,800
Answer:
A. $22,032
Step-by-step explanation:
FICA includes both social security tax (6.2%) and Medicare tax (1.45%), for a total tax rate of 7.65%.
0.0765 × $288,000 = $22,032 . . . FICA tax
Answer:
It is A $288,000
