Answer:
d + q = 50
0.10d + 0.25q = 7.30
Step-by-step explanation:
Since all of the 50 coins are dimes and quarters, we can write the equation:
d + q = 50, where d is the number of dimes and q is the number of quarters
Now, we know that dimes are 10 cents, or $0.10 and quarters are 25 cents, or $0.25. So, if we multiply 0.10 by d, we get the total value of the dimes, and if we multiply 0.25 by q, we get the total value of the quarters. The total value of all dimes and quarters is 7.30, so we have the equation:
0.10d + 0.25q = 7.30
Thus, the system is:
d + q = 50
0.10d + 0.25q = 7.30
Answer:
12.52 in.
Step-by-step explanation:
Area of square(A)=157in^2
length of square (l)=?
we know,
A=l^2
or,sqrt 157=l
12.52 in=l
Answer:
y = x / 7
Step-by-step explanation:
For us to get direct variation equation, we must introduce a constant term.
If y varies directly as x:
y ~ x
y = Kx
Where K, is the introduced constant.
Now let's solve to get a direct variation equation.
When y=3 , x=21
We substitute, y=3 and x=21 in the
y = Kx
3 = K 21
Divide both sides by 21
3 / 21 = K 21/ 21
K = 3/21
K = 1 / 7
Therefore, we introduce K = 1 / 7 into the mother equation.
y = 1/7 * x
y = x / 7
The direct variation equation for the situation:
y = x / 7
