Answer:
x= 35
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees.
102+43=145
180-145=35
The heat transfer is D. Radiation
Radiation consists of heat and light which are relevant in this case
What t value will yield 4?
H(t) = 4t + 20
How about -4?
H(-4) = 4(-4) + 20
H(-4) = -16 + 20
H(-4) = 4
Yes, t = -4
Done.
Answer:
Step-by-step explanation:
Consecutive integers just means like one after another.
This means that:
First number = x
Second number = x + 1
Third number = x + 2
They've told us that the sum of 3 consecutive integers is 78.
First number + second number + third number = 78
Sub the equations we wrote into the formula above and we get:
x + x + 1 + x + 2 = 78
Gather the like terms.
3x + 3 = 78
Subtract 3 from both sides.
3x = 78-3 = 75
Divide both sides by 3 to solve for x.
x = 75/3 = 25
If you look at the very beginning we said that the first number = x.
Therefore it is 25.
Second number = x + 1 = 26
Third number = x + 2 = 27
