The system of equations that can be used to determine the number of small tables and the number of large tables the designer will make is:
y -x = 8
$12y - $6x = $236
<h3>Defining the variables </h3>
Let:
x = number of large tables the designer can make.
x = number of small tables the designer can make.
<h3>Simultaneous equations</h3>
Simultaneous equations are sets of equations that must be solved together in order to determine the required variables. Methods of solving simultaneous equations include:
- Elimination method
- substitution method
- Graph method

1.) Substitute into the inequality is it true:
1 < 2(-4)+5
1 < -3 False so the answer is b. No
2.) since y < the expression for the line, shade below
51.82 miles in one hour, so 51.28 x 3 = <span>155.46 miles in 3 hours.
Your answer is </span><span>
155.46 miles in 3 hours.</span>
Answer:
For part 1- y=50x+75 For part 2- y=325
Step-by-step explanation:
the cost is increasing 50 for every hour
there is a flat rate of 75 to answer a house call
y=50x+75
y=50(5)+75
y=250+75
y=325
Answer:
2.79 * 10^4
Step-by-step explanation:
6.4 x 10^3+ 1.4 x 10^4+ 7.5 x 10^3
The exponents need to be the same
6.4 x 10^3+ 14 x 10^3+ 7.5 x 10^3
Add the numbers
6.4 + 14+ 7.5 =27.9
Multiply by the exponent
27.9 * 10 ^3
But this is not in scientific notation
Move the decimal one place to the left and add one to the exponent
2.79 * 10^4
