Answer:

1)

Isolate for the variable m

-13 = 5  + 20m -2m

-13 = 5 + 18 m

-18 = 18 m

m = -18/18

m = -1

2) same thing

11 + 8r = -r +29

8r + r = 29 - 11

9r = 18

r = 18 / 9

r = 2

3) same thing

4x +6 +3 = 17

4x = 17 - 6 - 3

4x = 17 - 9

4x = 8

x = 8 /4

x =2

4) Same thing

-8(-8x - 6) = -6x -22

64x +48 = -6x -22

64x +6x = -22 -48

70x = -70

x= -70/70

x = -1

Morgan’s grandmother orders her groceries online and has them delivered to her house. Her bill is $120. She has a coupon for 20%
iragen [17]

Answer:

The total price of the groceries, including discount and tip is $110.4.

Step-by-step explanation:

Here, the bill amount of groceries   = $120

Now, the coupon off  = 20%

Calculating the discount, we get

20% of bill amount $120  =   20% of 120  = \frac{20}{100}  \times 120  = 24

So, the 20% discount on the bill amount = $24

The actual payable amount = Bill Amount  - Discount

                                                =  $120 - $24  = $96

Now, 15% tip is also applied on the actual payable amount $96.

15% of 96 = \frac{15}{100}  \times 96  = 14.4

So, the total price t  = Payable amount + Tip amount

                                 = $96 +  $14.4   =  $110.4

or, t = $110.4

Hence, the total price of the groceries, including the discount and the tip  is  t = $110.4.

Find the value of x.
BartSMP [9]

Answer:

56

Step-by-step explanation:

We know that every triangle no matter will equal 180 degrees. So we will make an algebreic expression.

2x+8+60=180

When doing algebreic expression we want to simply as much as possible to find our answer. First we will do 60-180. Since the expression is adding 60 we want to do the opposite and subtract is by 60 on both sides. SO now we have 2x+8=120. We do the same thing with 8. Subtract it on  both sides since its adding in the expression. Now we have 2x=112. FInally, we will divide by two on both sides since its multiplying on the other side of the equation. So now we are left with x=56.
