Paraphin [41]

Answer:

<h2>B. (2, 1)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}-3y=x-5&\text{subtract x from both sides}\\x+5y=7\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}-x-3y=-5\\x+5y=7\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad2y=2\qquad\text{divide both sides by 2}\\.\qquad\qquad y=1\\\\\text{Put the value of y to the second equation:}\\x+5(1)=7\\x+5=7\qquad\text{subtract 5 from both sides}\\x=2

pentagon [3]

Answer:

Mr. Terry has $36.60 left after these purchases.

Step-by-step explanation:

10 x 0.58= 5.8

3. Add the solutions.

27.6+5.8=33.4

4. Subtract 33.4 from 70.

70-33.4=36.60

The product of two integers is 72. One number is two less than five times the other. Which of the following equations could be u
melisa1 [442]
Let the 2 integers be x and y.

Their product is 72, so we write: xy=72. (I)

One of them, say y, is 2 less than 5 times the other. We can write this as the equation:
                               y=5x-2. (II)

To find one of numbers, say x, we can substitute y with 5x-2, in the first equation:

xy=72,

x(5x-2)=72,

expanding the left hand side expression we get:

5x^2-2x=72.
