Answer:
5x + 6y = 20_____(1)
8x - 6y = -46_____(2)
Solving simultaneously:
Eqn(1) + Eqn(2)
5x + 8x + 6y + (-6y) = 20 + (-46)
13x = -26
x = -2
substituting this into Eqn (1):
5(-2) + 6y = 20
-10 + 6y = 20
6y = 30
y = 5
hence:
x = -2,y = 5.
Knowing that one dime has a 10 cent value and that a nickle has a 5 cent value, we can use multiplication or addition to find the answer.
5 x 10 = 50 5 dimes together are worth 50 cents.
2 x 5 = 10 2 nickles together are worth 10 cents.
50 + 10 = 60 5 dimes and 2 nickles are worth 60 cents when added together.

Step-by-step explanation:
0.40 ___0.04
We are given with two decimal numbers. Compare the numbers and complete the blank by < or > or =
To compare the decimals , compare each digit from left to right
0 is equal to 0
4 is greater than 0
so we can say 0.40 is greater than 0.04
0.40 > 0.04
Both decimal numbers are not equal
Answer:
0.40 > 0.04
