Answer:
There are 8 dimes there.
Step-by-step explanation:
This question is solved used a system of equations.
I am going to say that:
x is the number of nickels.
y is the number of dimes.
19 coins
This means that x + y = 19.
A nickel is worth $0.05. A dime is worth $0.1. The total of these coins is $1.35. So
0.05x + 0.1y = 1.35
How many dimes are there?
We have to find y.
From the first equation: x = 19 - y.
Replacing in the second:
0.05(19 - y) + 0.1y = 1.35
0.95 - 0.05y + 0.1y = 1.35
0.05y = 0.4
y = 0.4/0.05
y = 8
There are 8 dimes there.

10 decreased by 5 equals 5
Answer:
Hence option A and C are correct
Step-by-step explanation:
By putting value of 1.7 in each of the given equations of line as options should satisfy the equation
Option A
7– 7 = 3(1– 1)
0 = 0
Option B
y – 1 = 3(x – 7)
7-1 not equal to 3 (1-7)
Option C
y – 7 = 4(x – 1)
7 - 7 = 4 (1-1)
0 = 0
Option D
y – 1 = 4(x – 7)
7-1 is not equal to 4 (1-7)
