DON AND 3 FRIENDS SHARE 2 sandwiches at lunch which equation can be used to find out how much sandwich each person gets at the sandwich are shared equally
A. X= 4÷2
B. X= 2 ÷4
C. X= 1÷3
D. X= 1÷4​

Answers

Answer: B. x = 2/4

Reason:

The thing they need to share are the sandwiches (y), where x is the amount of sandwich per person, so that goes in the equation first.

4/2 is 2 so that doesn’t make sense.

C isn’t an option because there are 4 people in this word problem. Don and his 3 friends = 4.

D isn’t right because there’re 2 sandwiches, not 1.

Determine the value of the missing sides for the following triangle

Answers

Answer:

There is no picture or diagram so add them and i can edit this answer, look at paperclip sign first take picture screen shot then add pic on paperclip edit button here.

Step-by-step explanation:

For missing sides of a triangle we do the following.

Does it have a right Angle determine other angle measures, say if an external angle on a straight line showed 145 then its adjoing interior would be 180-145=35 degree.

Are the measure of the lengths congruent with a larger or smaller triangle shown.

If yes then if one triangle showed 4 and same triangle showed 6 and had ne missing, then the other had 8 and 10 and had one missing we would compare and if 8 was the same as 4 we would recognise the congruent triangle is x2 (scale factor 2) so measure 6 woyuld also be measure 12 for the other triangle. and then to find the smaller missing side we see 10 is left over and 10/2 = 5

Other ways to find length is through Pythagoras  we use the squares a^2 + b^2 = c^2 for missing slant

and c^2 - b^2 = a^2 for any missing side

so a represents any missing side for the second equation and c represents the missing side if it is a slant only.

Answer:

x = -9 1/2

y = -16 1/2

Step-by-step explanation:

x - y = 7

solve the above for 'y':  -y = 7 - x

multiple each side by -1:  y = x - 7

now both equations are in 'y=' form

x - 7 = 3x + 12

-2x - 7 = 12

-2x = 19

x = -19/2 or -9 1/2

-9.5 - y = 7

-y = 16.5

y = -16.5 or -16 1/2

The correct answers are, length is 21 inches, and the width is 10 inches.


L=length; W=width.

L-2W=1
L=2W+1

P=2(L+W)
62in=2((2W+1)+W)
31in=3W+1
30in=3W
10in=W
The width is 10 inches.

L=2W+1=2(10in)+1=20in+1in=21in
The length is 21 inches.

Proof ;)
P=2(L+W)
62in=2(21in+10in)
62in=2(31in)
62in=62in

Elliot has 4 1/3 candy bars. He gives 2/3 of a candy bar to Sara and 1/3 of a candy bar to Bill. How much does Elliot have left? (Work it out)

Answers

Answer:

10/3 or 3 1/3

Step-by-step explanation:

4 1/3= 13/3 as a mixed fraction

he gives 2/3 to sara:

13/3 - 2/2= 11/3

then he gives 1/3 to bill:

11/3-1/3= 10/3

he has 10/3 which is equal to 3 1/3

5. An equivalent expression is (6)^5. (6)^- 7  True

Step-by-step explanation: Not true. The 6 without an exponent is equivalent to the 6 having a 0 exponent.

Any number having an exponent zero has a value equal to 1.

6 · (6)^0 · (6)^–3
