Answer:
90
Step-by-step explanation:
75 × (20/100) = 15
75+15=90
The answer is I solution because all the X's end up making zero and u are only left with the answer 11=12
Answer:
x=-7, y=-5. (-7, -5).
Step-by-step explanation:
2y+x=-17
5x-4y=-15
---------------
x=-17-2y
5(-17-2y)-4y=-15
-85-10y-4y=-15
-85-14y=-15
14y=-85-(-15)
14y=-85+15
14y=-70
y=-70/14
y=-5
2(-5)+x=-17
-10+x=-17
x=-17-(-10)
x=-17+10
x=-7
Answer:
A=3Bz/2
B=2A/3z
Step-by-step explanation:
if you need more explanation you can ask me :)
I don't have a visual I can provide, but the ratio of the areas is the square of the ratio of the perimeters of a 2D figure.
Intuitively, you can imagine that the triangle is simply being "scaled up" by a factor of 7/3, so the base scales up to 7/3 its original length and the height becomes 7/3 its original height.
Therefore, the new ratio is the square of the ratio of the perimeters, which is 9:49.
