traffic signs are regulated by the manual on uniform control devices. the perimeter of some traffic sign must be 128 inches. Also its length is 6 inches longer than its width. Fin the width and the length of the sign.

Solve the system of equations using elimination x+y=13, x+2y=11 QWhat is the solution, and type an ordered pair.

math 
Ms. Sue,
Assuming the sign is a rectangle 
P = 2L + 2W
128 = 2(W + 6) + 2W
128 = 4W + 12
116 = 4W
29 = W

Ms. Sue,
I don't know how to solve your second problem.

I need to find an ordered pair and graph x+y =13, x+2y = 11

Solve the system of equati(a) symbolically,(b) graphically, and (c) numericallyons6x+2y= 6, 12x +3y =  12. Find the ordered pair or is it innitely with many solutions or no sultion. i need to graph it also. And also i need to complete the table of values. y = 3x +3, y = 4x 4 and find a odered pair and graph it

Ms. Sue,
I'm sorry you didn't understand my directions above.

x+y=13, x+2y=11 QWhat is the solution, and type an ordered pair.
x + y = 13
x + 2y = 11 add the two equations to eliminate x

0 + 3 y = 24
y = 8
go back and get x
x + 8 = 13
x = 5
(5,8)

6x+2y= 6, 12x +3y =  12. Find the ordered pair or is it innitely with many solutions or no sultion.

double the first equation
+12 x + 4 y = +12
12 x + 3 y = 12

7 y = 0
y = 0
go back and get x
12 x + 0 = 12
x = 1
(1,0)
i need to graph it also. And also i need to complete the table of values. y = 3x +3, y = 4x 4 and find a odered pair and graph it

A hardware supplier manufactures three kinds of clampos. Types A,B,C. Productionrestrictions force it to make 20 more type C clamps than the total of the othertypes and twice as many type B clamps as type A clampos. the shop must producew 320 clamps per day . How many of each type are made per day. how many type a clamps are produced? How many type B clamps are produced. How nmany type C clamps are produced?

math 
Damon,
y = 3x +3, y = 4x 4 and find a odered pair and graph it
y = 3x + 3
y = +4x  4 subtract

0  7 x + 7
7x=7
x = 1
go back for y
y = 3(1) + 3
y = 0
so
(1,0)
To graph these lines look for the x and y axis intercepts
for example for the line
y = 3 x + 3
when x = 0, y = 3 so mark (0,3)
when y = 0, x = 1 so mark (1,0)
draw a straight line through those two points. 
math 
Damon,
c = 20 + a + b
b = 2 a
a + b + c = 320


substitute 2 a for b
c = 20 + a + 2 a = 20 + 3 a
a + 2 a + 20 + 3 a = 320
6 a = 300
a = 50
then b = 100
then c = 20+150 = 170

Now please do what Ms. Sue said and post new questions as new math questions, not under your old one. Teachers will miss them here thinking Ms Sue and I have already answered them.

the traffic signs are regulated by the manual on uniform traffic signs must be 128 inches. Also length is 10 inches longer than width find the dimensions of this signs
