Answer
The initial temperature was T = -7 degrees
Step-by-step explanation:
Let the initial temperature be T.
- The tempature was very cold
Temperarure = T
- Then it doubled
Temperature = 2T
- Then it dropped 10 degrees
Temperature = 2T - 10
- And then it increased by 40 degrees.
Temperature = 2T - 10 + 40 = 2T + 30
The tempature is now 16 degrees
Temperature = 16 degrees
2T + 30 = 16
2T = -14
T = -7 degrees

Hey mate. Here is your answer.
Set up the composite function and evaluate.
g (17x^2 - 10x) = 153x^2 - 90x - 9
Hope this helps.
The answers is 2 x 3 x 6 = 36
Step-by-step explanation:
a)42
b) triangle and Parallelogram
c) for triangle: (base× height)÷2
for Parallelogram: (base×height)
d) triangle: (6×6)÷2=18
Parallelogram: 6×4=24
18+24=42
if it is unclear or you need more explanation, ask freely. if the answer is correct please give me brainliest i need 3 brainliests
1 1/4 + 1 1/2
First change the mixed fractions into improper fractions.
Do this by multiplying the denominator by the whole number, then adding that to the numerator, leaving the denominator the same.
5/4 + 3/2
Now change the fractions so that they have a common denominator.
Here, you can use 4 as the CD, so leave the first fraction alone and just change 3/2.
3/2 = 6/4
5/4 + 6/4 = 11/4
11/4 can be changed into 2 3/4.
So the answer is 2 3/4 or 2.75.
