x/6+4= 15
Subtract 4 from both sides; 4s cancel each other out
x/6+4-4= 15-4
x/6= 11
multiply both sides by 6 to eliminate fraction (multiply by reciprocal of 1/6)
(x/6)(6)= (11)(6)
x= 66
ANSWER: x= 66

Answer:
????????im i dont know
Step-by-step explanation:
x = 36
pentagon has 5 sides . The formula n/360 gives you the measure of each angle in a regular polygon. So in this case n ( stands for number of sides) is 5. Sum of exterior angle of a any polygon is 360. The measure of 1 exterior angle is given. It is 2x.
Now using ALGEBRAIC EXPRESSIONS we can write it as 5/360 = 2x
which is 72=2x
which is 72/2 = x
which is 36 = x
so x = 36.
Answer: y - 0.18y
Step-by-step explanation:
From the question, Emerson practice a game that was on sale for 18% off the sales tax in his country.
Let y represent the original price of the game. The be used to determine the final cost of the game will be:
We have to subtract the 18% discount from the original price to get the final cost of the game. This will be:
= y - (18% of y)
= y - (18/100 × y)
= y - (0.18 × y)
= y - 0.18y
The final expression is y-0.18y
Answer:
£5650
Step-by-step explanation:
The money max invested in the saving bond = x
After one year the intrest will be 2% of x
Amount = £5763
Amount = Principcal + Interest
= £5763 = x + 2% multiplied x
£5763 = x + 2x/100
= 50x/50 + x/50 = 5763
= 51x/50 = £5763
51x = 5763x50
51x = 288, 150
x = 288,150/51
x = 5650
So the money max invested = £5650
