Hey there!
To start, the dividend is always the number you are dividing from while the the number dividing the dividend into the quotient is called the divisor.
In the expression 45 divided into 9, or 45÷9, the dividend would be 45 since you are dividing 45 into 9 parts.
Hope this helps and have a nice day!

Step-by-step explanation:
You will have to repay the government
Step-by-step explanation:
If x is the mass of 30% copper alloy, and y is the mass of 65% copper alloy, then:
x + y = 80
0.30x + 0.65y = 0.51(80)
Solving the system of equations using substitution:
0.30x + 0.65(80 − x) = 0.51(80)
0.30x + 52 − 0.65x = 40.8
11.2 = 0.35x
x = 32
y = 80 − x
y = 48
The metalworker needs 32 kg of 30% copper alloy and 48 kg of 65% copper alloy.
