Answer:
85 messages
Step-by-step explanation:
The system of equations for this is
35 + .10x
18 + .3x
where x = the number of text messages
Usually, you would use substitution or elimination to solve this problem. However, because the answer choices were given, you can just plug in the values.
When you plug in 85, or x = 85, you get 43.5 for both equations because
35 + .10(85) = 43.5 18 + .3(85) = 43.5
Therefore, the answer would be 85 messages becuase both plans will cost the same when you send 85 text messages!

See the attached for the polynomial long division.
The dimension of the rectangle prism is : 3 1/2 mm , 9 mm and 8 1/2 mm
Express the mixed fraction into decimal :


So, the dimensions are : 3.5mm , 9mm & 8.5mm
Volume of the prism = Length x Breadth x Height
Susbtitute the value and simplify :
Volume of the prism = ( 3.5 x 9 x 8.5 ) mm
Volume of the prism = 267.75 mm
