Answer:
the amount, level, or extent to which something happens or is present.
Step-by-step explanation:
First equation: -8x+7y=-17
Second equation: y=2x+1
Take the value of y from the second equation, as y is already isolated, and plug it in for y in the first equation. Simplify and solve for x.
-8x+7(2x+1)=-17
-8x+14x+7=-17
6x+7=-17
6x=-24
x=-4
Take the value of x we just found and plug it into the first equation. Solve for y.
-8(-4)+7y=-17
32+7y=-17
7y=-49
y=-7
Hope this helps!! :)
Let the price before increase be Rs.100
Then , as the tpercentage increase =25%
Therefore, increase in price =
100
25
×100
=Rs.25
Therefore increased price =Rs.125
Therefore the percentage by which house wife should decrease the consumption be(

25
×100)%
=20%
Answer:
6.75 ft^2
Step-by-step explanation:
The area of the seat can be calculated as follows
a + b/2 × h
6+3/2 × 1.5
9/2 × 1.5
4.5× 1.5
= 6.75 ft^2
Hence the area of the seat is 6.75ft^2
