Answer:
y=42
Step-by-step explanation:
7y = 6×49
y = (6×49)÷7
y= 42
Answer:
C angle 2
Step-by-step explanation:
Supplementary angles add to 180 degrees (or form a straight line)
The angles that form a straight line line angle 4 are either 2 or 3
Answer:
hours
Step-by-step explanation:
Whenever 2 quantities (suppose a and b) are inversely proportional to each other, we can write an proportionality equation (with k as proportional constant) as:

Since, here t is INVERSELY PROPORTIONAL to r, we can say:

Firstly, we have t = 2 hour and r = 40 mph, so we find k:

Now, secondly, we have r = 45 and k = 80, we need to find t:

So, it would take
hours


You changed the mixed numeral into a fraction correctly.
Now you need to multiply the fractions.
Multiply the numerators together, and multiply the denominators together.

Now we could multiply out the numerator and denominator, and then we'd need to reduce the fraction, but before we multiply, we see there is a factor of 5 both in the numerator and in the denominator, so we can reduce before we multiply.


Hello there!
(Equation #1) 32 + 12 = 44
(Equation #2) 6 - 3 = 3, 3 x 8 = 24
These both equations don't have the same answer, even though it says that they are equal with each other, if you could correct these these 2 equations I am willing to answer again.
Hope this helped!!
