Answer:
Sajini = 200
Drea = 225
Step-by-step explanation:
d = amount Drea earned
s = amount Sajini earned
Together they earned 425
d+s =425
d = s+25
The system of equations
d+s =425
d = s+25
I will use substitution to solve
Substitute d= s+25 into the first equation
d+s =425
(s+25) + s = 425
Combine like terms
2s+25 =425
Subtract 25 from each side
2s+25-25 =425-25
2s = 400
Divide by 2
2s/2 =400/2
s =200
Sajini = 200
Now we need to find d
d = s+25
d = 200 + 25
d = 225
Drea = 225
Answer:
3/8
Step-by-step explanation:
2/8 + 1/8 = 3/8
Euclidean space, the sum of measures of these three angles of any triangle is invariably equal to the straight angle, also expressed as 180 degress
Answer:
x = 55
Step-by-step explanation:
x + (2x+15) = 180
3x + 15 = 180
3x = 165
x = 55
<u>Answer:</u>
c = 2.25
<u>Step-by-step explanation:</u>
For the given equation, we can find the value of c by dividing the numerical coefficient of the left-hand side of the equation by 2 and squaring the quotient obtained.

Solving for c to get:

It means that this value of c is added to both sides of the equation.
