First you have to find out how much one pen costs. To do that, all you have to do is divide $11.77 by 11. So,
$11.77/11=$1.07
Then it's just trial and error from there in till you find one that matches. So,
A. 4*$1.07= $4.28( This one is wrong )
B. 5*$1.07= $5.35( This one is wrong )
C. 6*1.07= $6.42 ( !!This one is RIGHT!! )
D. 7*1.07= $7.49 ( This one is wrong )

First we need to know how much each pen costs.  So we take 11.77 and divide it by 11.  That gives us 1.07 per pen.  So answer choice A has 4 pens for 4.44, so we need to multiply 1.07 x 4.  That gives you 4.28, so we know that isn't the correct answer.  For option B, we need to multiply 1.07 x 5.  That is 5.35, so that also can't be the answer.  For C, we need to do 1.07 x 6, and that gives us 6.42.  So we know the correct answer is option C.

Help pls 2,4 +0,8=........+1,21=........+1,78=........-5,14=
Mrrafil [7]
Lets write this out:-

2.4 + 0.8 = ________ + 1.21 = ______ + 1.78 = ______ - 5.14 = _____

So to solve d blanks we will do d following:-

2.4 + 0.8 = 3.2

Now lets write this out AGAIN.

2.4 + 0.8 = 3.2 + 1.21 = ______ + 1.78 = ______ - 5.14 = ____

Now lets solve again:-

3.2 + 1.21 = 4.41 

Now lets write this out AGAIN.

2.4 + 0.8 = 3.2 + 1.21 = 4.41 + 1.78 = ______ - 5.14 = ____

Now lets solve again:-

4.41 + 1.78 = 6.19

Now lets write this out AGAIN.

2.4 + 0.8 = 3.2 + 1.21 = 4.41 + 1.78 = 6.19 - 5.14 = ____

Now lets solve again:-

6.19 - 5.14 = 1.05

Now lets write this out AGAIN.

2.4 + 0.8 = 3.2 + 1.21 = 4.41 + 1.78 = 6.19 - 5.14 = 1.05

So, 2.4 + 0.8 = 3.2 + 1.21 = 4.41 + 1.78 = 6.19 - 5.14 = 1.05

Hope I helped ya!! xD

Solve for g.<br> −3+5+6g=11−3g
Nataly_w [17]

Answer:

g = 1

Step-by-step explanation:

-3 + 5 + 6g = 11 - 3g

2 + 6g = 11 - 3g

Add 3g to both sides.

2 + 9g = 11

Subtract 2 from both sides

9g = 9

g = 1
