The small dish costs $2 each and the large dish costs $4 each,
2(3)+4(2)=6+8=14
2(4)+4(1)=8+4=12
For me being 100% honest:
grade 9-11 no homework, pay attention in class and study night before.
Grade 12: pay attention more in class, do some homework when concepts hard, study night before.
Uni: Read notes, do class homework, read textbook, study week before.
Answer:
Step-by-step explanation:
step 1
Find the volume of the trapezoidal prism
The volume of the prism is equal to
where
B is the area of the trapezoidal face
L is the length of the prism
Find the area of the base B
we know that
The area of a trapezoid is equal to
we have
substitute
step 2
Find the mass
Remember that
The density is equal to divide the mass by the volume
so
we have
substitute
solve for the mass
Convert to Kg
Remember that
therefore
<span>Hello,
For this 12x-3x+11>4x-(17-9x)let's rewrite it as:
12x-3x+11>4x-17+9x
Now combine like terms:
9x+11>13x-17
Subtract 9x and add 17 to get:
28>4x
Divide by 4:
7>x or rewritten as:
x<7
Make sense?</span>
Answer:
The answer I beliebe is n=13.
Hope this helps you.
