Answer: x = 17
Step-by-step explanation: combine all of those numbers.
3x+x+22.
Combine like terms, so
4x + 22 = 90 (90 is the sum of 2 complementary angles)
Subtract 22 from both sides to get
4x = 68
Now divide by 4 to get x which is
x = 17
Answer:
1/6
Step-by-step explanation:
First convert 4.2m to cm
100cm = 1m
x = 4.2m
x = 4.2 * 100
x = 420cm
70cm to 420cm = 70/420
70/420 = 7/42
7/42 = 1/6
Hence 70 cm as a fraction of 4.2 m is 1/6
-46
52-16=negative 46 because shes still below sea level
Answer: 2n-8
Explanation: 2(n-6)+4 you bring 2 into the parentheses so 2 x n is just 2n
then 2 x -6 = -12
New equation 2n-12 +4
Now you combine-12 and 4 which is -8
Finale equation: 2n-8
