Answer: 306 (good chance its wrong)

Step-by-step explanation:If 167 like snickers and 139 like reese's then all we have to do is add 167 with 139 which adds up to 306

Rudy invested $2460 in a money market account for 3 and 1/2 years. He earned $452 in simple interest. Which best represents the
antiseptic1488 [7]

Answer:

B. 5 and 1/4 percent

Step-by-step explanation:

Step one:

given

principal= $2460

time= 3 and 1/2 years= 3.5 years

SI= $452

Required

The rate

Step two:

we know that

SI= PRT/100

substituting our data we have

452= 2460*R*3.5/100

452=8610R/100

cross multiply

452*100= 8610R

divide both sides by 8610

45200/8610= R

R= 5.25%

R= 5 and 1/4 percent

Which shows the correct first step to solving the system of equations in the most efficient manner? 3 x + 2 y = 17. x + 4 y = 19
skelet666 [1.2K]

Answer: First option.

Step-by-step explanation:

<h3> The missing picture is attached.</h3><h3></h3>

You can use these methods to solve a System of Equations and find the value of the variables:

A. Substitution method.

B. Elimination method.

In this case, given the following System of equations:

\left \{ {{3 x + 2 y = 17} \atop {x + 4 y = 19}} \right.

The most efficient method to solve it is the Substitution Method. The procedure is:

Step 1: Solve for one of the variables from the most convenient equation.

Step 2: Make the substitution into the other equation and solve for the other variable in order to find its value.

Step 3: Substitute the value obtained into the equation from Step 1 and evaluate, in order to find the value of the  other variable.

Based on this, you can identify that first step to solve the given System of equations, is solving for "x" from the second equation:

x + 4 y = 19\\\\x=-4y+19
