How to solve 3x+7=2x+1 using Dcmam​

Mathematics
1 answer:
anyanavicka [17]2 years ago
6 0

Answer:

x = -6

Step-by-step explanation:

3x + 7 = 2x + 1

Subtract 7 on both sides to leave 3x alone

3x = 2x - 6

Subtract 2x on both sides to have X on one side only

3x - 2x = x

x = -6

I'm not entirely sure as to what Dcmam is but there is really not much else you can do to find this value of x, it's as simple as that.

Sophia owns a clothing store that sells graphic T-shirts. n is the number of
goldenfox [79]

Answer:

n = 150

Step-by-step explanation:

If n is the number of T-shirt sell each month, then the revenue function of Sophia's store is r = 21n .......... (1)

and the cost function of her store is C = 16n + 750 ........ (2)

Now, at break-even point, the revenue of a business is equal to its cost.

Therefore, r = C {From equations (1) and (2)}

⇒ 21n = 16n + 750

⇒ 5n = 750

⇒ n = 150

So, the break-even point of the store will occur when the number of T-shirt production is 150. (Answer)

Grant needs 2/3 cup of raisins and 3/4 cup of almonds to make trail mix, which statement can be used to find out if their are mo
mina [271]
To solve this problem, you must find a common denominator. First, you multiply the denominators together, then, multiply the numerator of the first fraction by the original denominator of the second fraction and vis-versa. 

3*4 = denominator of both
2*4 = numerator of first fraction
3*3 = numerator of second fraction

Your fractions should end up being 8/12 cups of raisins and 9/12 cup of almonds. You can now compare these fractions. 

Overall, there are 1/12 more almonds than raisins.
