Answer:
Conversion and substitution
Step-by-step explanation:
One way to find out if the expression is true, we can convert all the percentages into their decimal equivalence.
60% = 0.6
10% = 0.1
6% = 0.06
Now let's substitute the values.
0.06 = 0.6 x 0.1
0.06 = 0.06
Since 0.06 is equal 0.06, this then proves that it is true.

Answer: 138
Step-by-step explanation:
Answer:
6 × 9 = 54
42 ÷ 7 = 6
56 ÷ 7 = 8
Step-by-step explanation:
Given:
6 × 9 = 54
8 × 4 = 34
42 ÷ 7 = 6
64 ÷ 9 = 7
56 ÷ 7 = 8
Now it need to verify,
6 × 9 = 54 this is correct
42 ÷ 7 = 6 This is also correct
56 ÷ 7 = 8 This is correct
X = [-(-8) +/- sqrt((-8)^2 -4*41)] / 2
x = ( 8 + sqrt (-100) / 2 and (8 - sqrt(-100) / 2
