Step-by-step explanation:
Answer:
The answer is B. (-7,-2)
Step-by-step explanation:
Multiply the first equation by 7,and multiply the second equation by -6.
7(−3x+6y=9)
−6(5x+7y=−49)
Becomes:
−21x+42y=63
−30x−42y=294
Add these equations to eliminate y:
−51x=357
Then solve−51x=357for x:
−51x=357 Divide both sides by -51
x=-7
Write down an original equation:
−3x+6y=9
Substitute−7forxin−3x+6y=9:
(−3)(−7)+6y=9
6y+21=9(Simplify both sides of the equation)
6y+21+−21=9+−21(Add -21 to both sides)
6y=−12
y=-2
Answer:
Maximum number of months Abby can learn yoga is 25 months.
Step-by-step explanation:
We have given,
Total savings of Abby = $1325
Total charges to learn yoga is given as:
A fixed registration fee = $35
And a monthly fee = $50
Since the registration Abby pays only once. So we can calculate the remaining saving amount for Abby.
i.e Remaining saving amount after registration fee = $ (1325 - 35) = $1290
Now, from the remaining amount after paying registration fee , let the Abby learn yoga for x months.
To find maximum number of months we need to satisfy a equation given as:

or 
Since we got x ≤ 25.8 months ≈ 25 months (in integer form)
So maximum number of months Abby can learn yoga is 25 months.
Divide 4.10 by 7 to get about 0.59 (round up because you can't get part of a penny) and that gives you 1/8 of a yard's price. Then multiply that by 8 to get a full yard for $4.72.
