Answer:
Jennifer has 7 quarters
Step-by-step explanation:
<u><em>The correct question is</em></u>
Jennifer has $ 3.51 in change in her piggy bank. The change consists of 51 coins inducing pennies, nickels and quarters. If there are 3 times as many nickels as pennies, how many quarters does she have?
Remember that
Let
x ----> the number of pennies
y ---> the number of nickels
z ---> the number of quarters
we know that
-----> equation A
----> equation B
---> equation C
substitute equation C in equation A and equation B
-----> equation D
----> equation E
we have
-----> equation D
----> equation E
Solve the system of equations D and E by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (11,7)
x=11,z=7
see the attached figure
Find the value of y
so
The number of pennies is 11
The number of nickels is 33
The number of quarters is 7
Answer:
67 degrees
Step-by-step explanation:
first find angle abc by subtracting 68 from 101 == 33
then add it to half of 68 (34) to get angle abe
we know it is half because if there is a bisector, both angles cbe and ebd are equal
X intercept (6,0)
y intercept (-3,0)
slope is m= 1/2
Darnel needs to spend three days making jam if he wants to jar 15 liters.
Step-by-step explanation:
If you are to assume the relationship is proportional then if he makes 10 liters in 2 days you divide 10 by 2 and you get 5. This means he makes 5 liters a day. Then you add 5 to 10 and you get 15 which means you are adding another day(5) So he needs to work an extra day which would give you three dyas total. Hope this helped!
First and last ones
The " = [number] " at the end of an equation for a circle is the radius squared
So if the diameter is 12, then the radius is 6, and 36 is 6 squared
Also as long as the x term doesn't have an integer affecting it (like -3 or +5) then it'll stay on the y axis.
