Let's solve for x.
y=x−3
Step 1: Flip the equation.
x−3=y
Step 2: Add 3 to both sides.
x−3+3=y+3
x=y+3
Answer:
x=y+3
Let's simplify step-by-step.
−5x+9
There are no like terms.
Answer:
=−5x+9
Answer:
180mm^2
Step-by-step explanation:
CB = 15^2 + 6^2 = 261, the square root of 261 is ~16mm
CB is 16mm
the area of the triangle is A=ab/2
A=45mm^2
Now you need to find the area of the rectangle
A=l×w
A= 15×9= 135mm^2
now add both areas
(135+45)mm^2=180mm^2
Answer: 3.5a+5b=470 and a+b=115
