Answer:
X=75
Y=110
Step-by-step explanation:
A straight line is 180, so add the equations that make a line and set them equal to 180
x+20+x+10=180
Combine like terms
2x+30=180
Subtract 30 from both sides
2x=150
Divide by 2
X=75
Same for y
y+y-40=180
2y-40=180
Add 40 to both sides
2y=220
Divide by 2
Y=110
Answer:
agree with both because 1 dollar = 4 muffins so 2 x 4 = 8 muffins and 4x4 = 16 muffins
It takes 3 years for the balance of account to be $ 221
<em><u>Solution:</u></em>
From given information,
Principal = $ 200
Rate of interest = 3.5 %
Amount after "n" years = $ 221
To find: number of years
In simple Interest,
Simple interest = amount earned - principal
Simple interest = 221 - 200 = 21
Thus simple interest earned is $ 21
<em><u>The formula for simple interest is given as:</u></em>

Where,
p is the principal
n is the number of years
r is the rate of interest per annum
Substituting the given values in formula,

Thus it takes 3 years for the balance of account to be $ 221
The answer is -1 because I don’t really know the real answer
Answer:
True
Step-by-step explanation:
It has a common ratio of -1/2
Each term after the first is obtained by multiplying the previous one by -1/2:-
-1/2 * 1/2 = 1/4 ; 1/4 * -1/2 = -1/8 and so on.
