Answer:
-17
Step-by-step explanation:
You replace the t with 7 making the equation , f=-2(7)-3. Using PEMDAS, you solve -2 x 7 making it -14. Finally, subtract -3 from -14 making it -17.
Honestly, I don’t know the answer. Sorry. Better luck next time. Because of it being so hard.
Answer:
56
Step-by-step explanation:
Givens
Given Ratio = 2/5
Given mass on earth = 140
Ratio
2/5 = x/140 or
0.4 = x / 140
Solution
2/5 = x/140 Cross multiply
5x = 2*140 Combine
5x = 280 Divide by 5
x = 280/5
x = 56
You could also do this by combining the left side of the original proportion into 0.4
0.4 = x / 140 Multiply both sides by 140
0.4*140 = x Combine the left
56 = x
Answer: See below
Explanation:
8x + 14 = 10x - 10 (alt. exterior angle)
8x - 10x = -10 - 14
-2x = -24
x = -24/-2
x = 12
Now plug x = 12 in 10x - 10 to find the angle:
10(12) - 10 = 120 - 10 = 110 degree
