1. 8q + 6 ; q = 2
  = 8 ( 2 ) + 6
   = 16 + 6
  = 22 option D.

2. 9 + 4 ( -3 )
  = 9 - 12
  = -3 option A

3. 7 ( 4 ) - 7
   = 28 - 7
   = 21
option B

4. 10 - 3.2 ( 2 )
 = 10 - 6.4
= 3.6 option B

5. 12 (1.5) + 4
= 18 + 4 
= 22 option D.

6. 5w + 10 = 40  
    5w = 30 
   w = 6 option A.

7. 4y - 12 = 60
    4y = 72
    y = 18 option B

8 . 10k + 5 = 65
     10k = 60
     k = 6 option A

9. 2b - 15 = 33
    2b = 48
     b = 24 option C

10. 3d + 18 = 21
      3d = 3

A 2-pound bag of sugar contains 227 one-teaspoon servings and costs $2.49. A batch of muffins uses 1 2 cup of sugar. How many wh
ZanzabumX [31]

Answer:

a) 9 whole batches can be made

b) The cost of sugar for each batch = $0.26

Step-by-step explanation:

A 2-pound bag of sugar contains 227 one-teaspoon servings and costs $2.49.

This means:

2 pound bag of sugar = 227 teaspoon servings

2 pounds bag of sugar cost $2.49

We are told that:

A batch of muffins uses 1/2 cup of sugar.

a).How many whole batches can you make if you use as much of the sugar as possible?

(1 cup = 48 teaspoons)

Hence, A batch of muffins = 1/2 cups of sugar = 48 teaspoons of sugar ÷ 2

= 24 teaspoons of sugar

Hence:

24 teaspoons of sugar = 1 batch of muffins

227 teaspoons of sugar = x

Cross Multiply

24 × x = 1 × 227

x = 227/24

x = 9.4583333333 batches of muffins

We are asked to name the number of whole batches that can be made.

Therefore, 9 whole batches of muffins can be made

b) What is the cost of sugar for each batch? (do not consider leftover sugar in the cost calculation.) You can make a total of batches at $ per batch.

Since we are not to consider the leftover sugar in the cost calculation,

1 batch = 24 teaspoons of sugar

9 whole batches =

9 × 24 teaspoons = 216 teaspoons of sugar was used

The left over = 227 - 216 = 11 teaspoons of sugar is left

We know that:

227 teaspoons of sugar = $2.49

216 teaspoons of sugar = x

Cross Multiply

= 216 × $2.49/227

= $2.369339207

24 teaspoons of sugar = 1 batch of muffins

Therefore,

216 teaspoons of sugar =

$2.369339207

24 teaspoons of sugar =

24 × $2.369339207/ 216

= $0.2632599119

Approximately = $0.26

Therefore, the cost of sugar for each batch = $0.26

One truck delivered 3 4/5 tons of potatoes to a warehouse while another truck delivered 1/2 ton less. How many tons of potatoes
Savatey [412]
3 4/5 + (3 4/5 - 1/2) =
19/5 + (19/5 - 1/2) =
19/5 + (38/10 - 5/10) =
19/5 + 33/10 =
38/10 + 33/10 =
71/10 which equals 7 1/10 tons <==

How do I solve for X in x/2 + x-3/5= 3
alexandr402 [8]
First of all,we have to cancel off the denominator.

times 2 to the equation in order to cancel off the denominator "2"
(x2) x+2x-6/5=6
#all numbers in this equation will be timed by 2 as well

then times 5 to cancel off the denominator"5"
(x5) 5x+10x-6=30
#all of them are timed by 5

then u will see this equation:
5x+10x-6=30

plus up the unknown numbers,
15x-6=30

Move the negative number "-6" to the back of 30.

When negative number moved to the other side,it will become positive number.
Same as when positive number moved to the other side,it will become negative number.

Thus,
"-6” moved
become positive "6"
Usually positive means plus"+" while negative means minus"-".

15x=30+6
15x=36

Move 15 to the opposite side,
Timed by 15 become divided by 15.

Just like the positive and negative numbers,they forced to become the opposite things.
positive→negative OR negative→positive
plus→minus OR minus→plus
times→divide OR divide→times

Thus,
x=36÷15
OR u can write as fraction,
x=36/15
x=12/5

final ans:
x=12/5 OR 2.4
