Answer:
perimeter = 6x + 15
Step-by-step explanation:
The perimeter of the triangle is the distance around the triangle.
We need to apply our ability to convert word problems in to mathematical expressions.
We were told that the bottom of the triangle is x units.
From the diagram perimeter 4x + 12 + x + 3 + x = 6x + 15
Four times the length of the bottom will be 4x .
12 more than 4 times the bottom will be 4x + 12.
Hence another side of the triangle is 4x + 12.
Finally we were told that the last side is 3 more than the bottom, that will be x + 3.
16/25 because there are 3 face cards which have 4 different suits and 4 different suits for the number 6

Answer:
y= -8/11 x=-63/11
Step-by-step explanation:
Rewrite equation
Step: Solve6x+y=−10for y
Step: Substitute−6x−10 for y in 4x−3y=14
Step: Substitute −8
/11 for x in y=−6x−10
y= −62
/11 --- (Simplify both sides of the equation)
___________________________________________
y= -8/11
x=-63/11
