Answer:
Integers -4, -3, -2, -1, 0, 1, 2, 3, 4… all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero). Fractions and decimals are not integers. For example, -5 is an integer but not a whole number or a natural number.
Answer:
t > 4.5
Step-by-step explanation:
T = 5 - 2t
is the equation for the temperature after midnight.
-4 = 5 - 2t is the point of interest
-9 = -2t
t = 4.5 hrs so 4:30 is the time the temperature reaches -4
t > 4.5 hrs covers all the time that the temperature is less than -4
Answer:4x/5-1/5 = y
Step-by-step explanation:
We need to get y by itself
4x+2=5y+3
subtract 3 from both sides
4x-1=5y
divide both sides by 5
4x/5-1/5 = y
1) 2 1/3 is also equal to 7/3
4 1/5 is also equal to 21/5
you need to make the denominators the same so you have to find the lowest common multiple, which is 15 since both 5 and 3 can be times by to make 15
you need to also times the numerators by the number you're timesing the denominator by
7/3 x 5 = 35/15
21/5 x 3 = 63/15
now add those together
35/15 + 63/15 = 98/15
now just convert 98/15 back to a mixed fraction
98/15 = 6 8/15
the answer is..
I'll do the others in a different answer!!
Answer:
Step-by-step explanation:Simplifying
25y = 35
Solving
25y = 35
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '25'.
y = 1.4
Simplifying
y = 1.4
