Answer:
$2.60
Step-by-step explanation:
first you need to see how many time 2.90 goes into 20 it is 6, so then you multiply 2.90 times 6 and get 17.40. Lastly you subtract 17.40 from 20 to get 2.60
Hope this helps

Yes, in my opinion I think a bar model would be a good model for converting miles to feet. It is simple and easy to understand
<span>If you are spreading fertilizer on a golf course at the rate of 40 pounds per 10,000 square feet and the course is 320 acres, you can calculate the amount of fertilizer that will be needed by converting acres to square feet. So, 320 acres are 13,939,200 square feet which means you will need 55,756.8 pounds of fertilizer. </span>
The obtained two numbers by substitution method are 5 and 12.
<h3>What is substitution method?</h3>
The algebraic method for solving simultaneous linear equations is the substitution method.
- The value of one variable through one equation is substituted in the second equation, as the name implies.
- To verify an equation system by substitution, enter your x and y values into the initial equations.
- Your answer is accurate if both simplification expressions are true.
Let the first number be 'x'.
Let the second number be 'y'
From the given condition that second number is 3 times 1 less than the first number.
That is;
y = 3(x - 1)
Now the sum of both number are given as 17.
x + y = 17.
Use substitution method, and put the value of y in the total sum.
x + y = 17.
x + 3(x - 1) = 17
Simplify the given equation;
x + 3x - 3 = 17
4x = 17 + 3
4x = 20
x = 5 (first number)
Put the value of x in y to find the value.
y = 3(x - 1)
y = 3(5 - 1)
y = 12 (second number)
Therefore, the values of two numbers are 5 and 12.
