Mary is painting pumpkins to earn money. She plans on selling each pumpkin for $7.50. She currently has $200 in her savings acco
bixtya [17]

Answer: No. It's not proportional

Step-by-step explanation:

The direct proportion in mathematics is expressed as:

y = kx

where

y = $200

k = constant

x = $7.50

We then solve for k

y = kx

200 = 7.50k

k = 200/7.50

k = 26.67

Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.

krek1111 [17]

Answer:

a=-3

Step-by-step explanation:

we have

a-2=\frac{3+6a}{3}

Solve for a

That means ----> Isolate the variable a

Factor 3 in the numerator right side

a-2=\frac{3(1+2a)}{3}

Simplify right side

a-2=1+2a

subtract a both sides

a-2-a=1+2a-a

-2=1+a

subtract 1 both sides

-2-1=1+a-1

-3=a

Rewrite

a=-3
