Answer:
$218
Step-by-step explanation:
$100 times 100% = $200
9% of 200 = 200X.09 = 18
200 + 18 = 218
5x + 3y = 2
10x + 7y = 5
Use the substitution method. Solve for x in the first equation.
5x + 3y = 2
Subtract 3y from both sides.
5x = 2 - 3y
Divide both sides by 5.
x = 2/5 - 3/5y
Now plug in x into the second equation, 10x + 7y = 5.
10(2/5 - 3/5y) + 7y = 5
Multiply (2/5 - 3/5y) by 10.
4 - 6y + 7y = 5
Combine like terms.
4 + y = 5
Subtract 4 from both sides.
y = 1
Now plug y back into the first equation, 5x + 3y = 2.
5x + 3(1) = 2
5x + 3 = 2
Subtract 3 from both sides.
5x = -1
Divide both sides by 5.
x = -1/5
y = 1
Answer:commen factoers is what you need 2 4 8 16 and so on
Step-by-step explanation:
To add mixed numbers, we first add the whole numbers together, and then the fractions. ...
If the denominators of the fractions are different, then first find equivalent fractions with a common denominator before adding. ...
Subtracting mixed numbers is very similar to adding them.
Answer:
$36.8
Step-by-step explanation:
to find the total amount, you must do 32 x 115% aka 1.15
32 x 1.15 = 36.8
Therefore $36.8 is the total amount Paulie needed to pay!
Answer:
1. A. Set the angle and arc measures equal.
2. B. major arc
3. B. Multiply the angle measure by 2.
4. A. minor arc
Step-by-step explanation:
1. If the intercepted arc is made from a central angle then angle of arc is equal to the central angle
2. 190 is a bigger angle than 170(angle of the remaining arc)
Therefore it is a major arc.
3.If the intercepted arc is made from a inscribed angle, then the angle of arc is double of the inscribed angle.
4. 115 < 245
Therefore it is a minor arc.
