Solve: S = n/2 (a+b) for b

IgorC [24]

Answer:

b = -n/(2-S) -a

Step-by-step explanation:

S = n/2 (a+b)

divide both sides by (a+b)

S/(a+b) = n/2

flip the equation on the left (it is the same equation just negative)

-(a+b)/-S = n/2

divide both sides by -S

-a-b = n/(2-S)

add a to both sides

-b = n/(2-S) +a

flip the sign (multiply/divide by -1)

b = -n/(2-S) -a

Answer:

Felicia is correct

Step-by-step explanation:

There are 180 degrees in a triangle

48.3 + 33.6 = 81.9

subtract 81.9 from 180 to get the measure of the last angle

180 - 81.9= 98.1

meaning Felicia is correct

Mary McDonald makes mugs in Miami. She makes two sizes of mugs: a small mug that she sells for $2.50 and a large mug that she se

IrinaVladis [17]

Mary McDonald sold 11 small mugs and 10 large mugs.

Step-by-step explanation:

Given,

Total cost of sold cups = $85

Cost of one small cup = $2.50

Cost of one large cup = $5.75

Cups at the start of day = 215

Cups at the end of day = 194

Cups sold = Cups at the start of day - Cups at end of day

Cups sold = 215 - 194 = 21

Let,

x represents the number of small cups.

y represents the number of large cups.

According to given statement;

x+y=21 Eqn 1

2.50x+5.75y=85 Eqn 2

Multiplying Eqn 1 by 2.50

$2.50(x+y=21)\\2.50x+2.50y=52.50\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(2.50x+5.75y)-(2.50x+2.50y)=85-52.50\\2.50x+5.75y-2.50x-2.50y=32.50\\3.25y=32.50$

Dividing both sides by 3.25

$\frac{3.25y}{3.25}=\frac{32.50}{3.25}\\y=10$

Putting in Eqn 1

$x+10=21\\x=21-10\\x=11$

Mary McDonald sold 11 small mugs and 10 large mugs.
