Answer: 5 nickels and 19 quarters
Step-by-step explanation:
Let represent the number of nickels and let represent the number of quarters.
From the problem we can write these two equations:
+ = 24; (0.05) + (0.25) = 5.00
Isolate in the first equation: = 24 − .
Substitute 24 − for and solve for :
(24 − )(0.05) + (0.25) = 5.00
24(0.05) − (0.05) + (0.25) = 5.00
1.20 − 0.05 + 0.25 = 5.00
1.20 + 0.20 = 5.00
0.20 = 3.80
= 19
Use = 19 to find :
+ = 24; + 19 = 24; = 5
Answer: 5 nickels, 19 quarters
Hope this helps!
T=0 is also a solution. Other than 0 here is a solution.
Answer:
12/15
Step-by-step explanation:
To find the answer to this question, we first need to align the numerators and find what multiplies by 4 to get 12.
This is achieved by dividing 12 by 4.
12 / 4 = 3
Now, we need to multiply 3 by the denominator (5) to get the missing denominator of the second fraction.
5 * 3 = 15 --> (Denominator)
Inputting the denominator into the second fraction, we have the fraction:
12/15
Answer:
60
Step-by-step explanation:
We can use the pythagorean theorem to find the leg.
10^2+x=13^2
x=12
We now find the area given the height of the triangle.
10 X 12=120
120/2=60
