Answer: 926.7°C
Step-by-step explanation:
1700°F=926.7°C
(1700°F-32)•5/9=926.667°C
926.667°C rounded to one decimal place 926.7°C
Let's solve this by substitution.
y is given by the 2nd eqn as y = (1/3)x + 7. Subst. (1/3)x + 7 into the first eqn as a replacement for y: x + 9( (1/3)x + 7) = 3.
clear out fractions by mult. all 3 terms by 3: 3x + 9x + 63 = 3
Combine like terms: 12x = -60. Then x = -5
Find y by subst. -5 for x in the 2nd equation: y = (1/3)(-5) + 7
= -5/3 + 35/3 = 30/3 = 10.
Thus, the solution (x,y) of this system is (-5,10).
Answer:
20 inches
Step-by-step explanation:
if one half is 6 and 4 inches then the other half is equal to that it would be 20 inches total.
Your answer would be 5/6 in its simplest form.
To add fractions we must get them both over the same denominator, which means we can multiply 3/4 by 3 to get 9/12.
Then we can add 9/12 to 1/12 to get 10/12, which simplifies to 5/6 by dividing by 2.

Answer:
2 roots.
Step-by-step explanation:
The roots are the same things as the x-intercepts. From -4 to 3, there are two times when the polynomial intersects the x-axis. So, there are 2 roots.
