Answer:
She will walk and run 148.2 miles in a year
Step-by-step explanation:
She walks: 0.75+0.5=1.25 miles each week
And: 1.25 *52=65 miles a year
She runs : 1.6 miles a week
And: 1.6*52 =83.2 miles a year
Total miles : 83.2+65=148.2 miles
Sorry, a bit late but i took it and it was A.
If you're asking for the number of digits smaller than 13 in the bag:12
Answer:
<h3>
( - 1 , - 1 )</h3>
Option D is the correct option.
Step-by-step explanation:
y = - 2x - 3 → Equation ( i )
y = 3x + 2 → Equation ( ii )
Using elimination method
y + 2x = - 3
y - 3x = 2
---------------------
5x = - 5
Divide both sides of the equation by 5

Calculate

Again, Putting the value of x in equation ( ii ) in order t get the value of y

plug the value of x

Any expression multiplied by ( - 1 ) equals it's opposite

Calculate

Therefore, The possible solution of the system is the ordered pair ( x , y )

-----------------------------------------------------------------------
Check if the given ordered pair is the solution of the system of equation


Simplify the equation


Since all the equalities are true, the ordered pair is the solution of the system.
<h3>
( x , y ) = ( - 1 , - 1 )</h3>
Hope this helps..
