The other number is -3.
Step-by-step explanation:
Step 1; First we develop formulae for the given information. A number is added with 3 and the resulting sum is multiplied by 4. This number is then divided by 2 and the quotient is 0. Assume the unknown number is x, then the given information is as follows
The quotient of
is 0. So
= 0.
Step 2; Now we solve the above equation. The denominator is taken to the RHS and the RHS remains zero.
= 0, 4(x+3)= 0, 4x+ 12 = 0, 4x = -12, x =
= -3.
So the other number is -3.
Answer:
3. adjacent; 49
4. adjacent; 71
5. verticle; 41
6. adjacent; 14
Step-by-step explanation:
ok basically if the angles are next to each other, then they're adjacent and if they're across from eachother they're verticle.
to find 3:
set both equations equal to each other and solve because verticle angles are equal
to find 4:
add the 2 equations together and set it equal to 180 because adjacent angles add up to equal either a complementary angle or supplementary depending on the problem
Answer: 
Step-by-step explanation:



Answer:
7.4 · 10^4
Step-by-step explanation:
For scientific notation, multiplication is pretty simple.
In this case, you would only multiply the "regular" number by 2.
(3.7 · 2) · 10^4
= 7.4 · 10^4
However, if it were asking about multiplying the number with something else in scientific notation, in addition to what we did above, you'd add together the exponents.
I hope this helped!
