Arectangle's length and width are in a ratio of 5: 2. the area is 160 square centimeters. what are the length and width?
if you could solve this do so asap

Step-by-step explanation:

l - length

w - width

length and width are in a ratio of 5:2

          cross multiply

         divide both sides by 2

the area is 160cm²

We have the system of equations:

Substitute (1) to (2):

Put the value of w to (1):

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.

step-by-step explanation:

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
