Answer:
I believe the answer is = 6,-6
Since they want a product, that means multiplication. We want to multiply a whole number and a fraction to get 5/3. When we multiply fractions, you multiply across the numerator and across the denominator. So in this case we want to multiply 2 numbers to get 5 a decimal 2 numbers to get 3. Each of these numbers only have 2 factors so
5 × 1 = 5 and
3 × 1 = 3
So we are going to multiply
5 × 1/3 =
5/1 × 1/3 = 5/3
Answer:
It decreased
Step-by-step explanation:
It decreased. Assuming that the temperature is 100 and it is now reduced by 60% then the temperature will be at 40 and if it increased by 80% then the final temp is 72. So it is 48% of the original temp.
Answer:
No, Richard is incorrect, the current temperature is 40 degrees.
Step-by-step explanation:
4x-40=3x
4x-3x=40
x=40
