Answer:
x = 4
Step-by-step explanation:
180° - 114° = 66°
15x - 6 = 66
15(4) - 6 = 66
60 - 6 = 54
Statement is wrong because we can see another angle. so...
Final answers: x = 4 while 54 + 114° = 168° then 180° - 168° = 12°
Answer:
C) 5.5 h
Step-by-step explanation:
Plug in the values
253.55 = 46.1 * t
Then solve for t by dividing both sides by 46.1 to get: C) 5.5 h
Answer:
900
Step-by-step explanation:
The ratio of the number of people who own a smartphone to the number of people who a flip phone is 5:3.
Let the number of people who own a flip phone=x
If 600 more people own a smartphone than a flip phone, then the number of people who own a smartphone=x+600
To find x, we express the ratio and population as an equality.
5:3=x+600:x
Expressing the ratios as fractions would give:

Next, we cross multiply
5x=3(x+600)
Open the brackets by expansion.
5x=3x+(3 X 600)
5x=3x+1800
Subtract 3x from both sides.
5x-3x=3x-3x+1800
2x=1800
Divide both sides by 2
x=900.
Since x=900, the number of people who own a flip phone is 900.
Answer:
The expression of amount of gas is 
Step-by-step explanation:
Given:
25 gallons of gas were pumped into two different size tanks.
Now, to express the amount of gas pumped into the smaller tank in terms of the amount
pumped into the larger tank.
Let the amount of gas pumped into smaller tank be 
And according to question, the amount of gas pumped into larger tank is
.
Total amount of gas pumped into both size tanks = 25 gallons.
So, to express the amount of gas pumped into the smaller tank in terms of the amount
pumped into the larger tank:

<em>Subtracting both sides by </em>
<em> we get:</em>

Therefore, the expression of amount of gas is 
Answer:
21 and 23
