Which expression is equivalent to 64 2/3 PLS HELP

The table below shows the number of miles Maggie ran and the number of calories she burned.

gulaghasi [49]

Answer:

The dependent variable is number of calories burnt.

Step-by-step explanation:

The dependent variable of an experiment is the variable under study, i.e. it is the variable that is being observed for any changes, when the other variables are changed.

The independent variable is the variable that is being altered to observe the changes in the dependent variable.

A dependent variable can be affected by one or more than one independent variables.

In this case, the data provided represents the number of calories Maggie burned based on the number of miles she ran.

So, the amount of calories burnt is dependent upon the number of miles covered running.

So, the dependent variable is the number of calories burnt and the independent variable is the number of miles she run.

Thus, the dependent variable is number of calories burnt.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-5y + 8x = -18

5y + 2x = 58

Step 2: Solve for x

Elimination

Combine 2 equations: 10x = 40
[Division Property of Equality] Divide 10 on both sides: x = 4

Step 3: Solve for y

Substitute in x [Original equation]: -5y + 8(4) = -18
Multiply: -5y + 32 = -18
[Subtraction Property of Equality] Subtract 32 on both sides: -5y = -50
[Division Property of Equality] Divide -5 on both sides: y = 10
