6a+14=-7-a

you simplify the equation to the form, which is simple to understand
6a+14=-7-a

you move all terms containing a to the left and all other terms to the right.
+6a+1a=-7-14

you need to simplify left and right side of the equation.
+7a=-21

you divide both sides of the equation by 7 to get a.
a=-3

I need help! The 20% off sale is a better deal than the $200 rebate or $150 coupon for the $1,500 dining room set. Explain why t

11111nata11111 [884]

Answer:

See explanation

Step-by-step explanation:

The 20% off sale is a better deal because 20% off of $1500 will cost $1200. (See work).

However, the 200 or 150 dollars off will cost $1300-1350. Thus, the better deal for the dining room set is to use the 20% off.

If their budget is $1250, they will be $50 under budget because they would be paying $1200 for the set.

Work:

1500 x 20%

1500 x 0.20 = 300

1500-300= $1200

1500-150= 1350

1500-200= 1300

Find the sum. (-7/2z+4)+(1/5z-15)

Dafna11 [192]

Answer:

-(33+110z)/10z

Step-by-step explanation:

(-7/2z +4)+(1/5z -15)

from BODMAS, solving the one in the bracket

First(-7/2z +4)+(1/5z -15)

Find the Lcm

[-7/2z +4] +[1/5z -15]

(7+8z)/2z +(1-75z)/5z

find the Lcm which is 10z

[5(-7+8z) + 2(1-75z)]/10z

[(-35+40z)+(2-150z)]10z

(-35+2+40z-150z)/10z

(-33-110z)/10z

-(33+110z)/10z
