Answer:
18 weeks
Step-by-step explanation:
80+15x=350
15x=270
x=270/15
x=18
The answers are P: (-4,3) Q: (4,-3)
Answer:
27 cm²
Step-by-step explanation:
Formula of Area Triangle = 1/2(base x height)
Base = 6 cm
Height = 9 cm
1/2 ( 6 x 9 ) = 1/2 ( 54 ) = 27
Units = cm * cm = cm²
27 cm²
<u>Why the formula (1/2 ( base x height )) works:</u>
Take a triangle
Duplicate the triangle
And rotate the triangle and put it next to the other one
What shape does it form?
Either a parallelogram or a rectangle
The formula for a parallelogram or rectangle is (base x height)
Since you are initially doubling the area of the triangle to get the rectangle, solve for the rectangle and divide by 2.
So, do base x height
And divide by 2

-Chetan K
Answer:
x = k/6 - 50/3
Step-by-step explanation:
K=6x+100
--> Swap sides so that all variable terms are on the left hand side.
6x+100=k
--> Subtract 100 from both sides.
6x=k−100
--> Divide both sides by 6.
6x/6 = k-100/6
--> Dividing by 6 undoes the multiplication by 6.
x = k-100/6
--> Divide k−100 by 6.
Answer : x = k/6 - 50/3

3a^3-5b^3+xa^3+yb^3=1a^3+1b^3
replace a^3 with z
replace b^3 with v (to make it easier to see)
3z-5v+xz+yv=z+v
3z+xz+yv-5v=1z+v
the terms match them
3z+xz=1z
divide both sides by z
3+x=1
minus 3
x=-2
yv-5v=1v
dividie both sides by v
y-5=1
addd 5 to both sides
y=6
(3a^3-5b^3)+ <u>-2</u> a^3 +<u>6</u> b^3=(a^3+b^3)
