Find the ratio of the known sides.
6/4 = 1.5
The larger triangle is 1.5 times larger than the smaller one.
Area is in square units, so to find the area of the larger triangle square the ratio and multiply that by the area of the known triangle.
1.5^2 x 40 = 90 square cm.
4x10^7 The number of zeros the given number has would be the exponent
Cost per bottle
6 pack is 3.79 so the cost per bottle is 3.79/6=$0.631666666666667 per bottle
9 pack is 4.50 so the cost per bottle is 4.50/9=$0.50 per bottle
12 pack is 6.89 so the cost per bottle is 6.89/12=$0.574166666667 per bottle
0.63>0.57>0.50
the one that costs the least per bottle is the 9 pack which costs $0.50 per bottle
Answer:
x=1, y=-6. (1, -6).
Step-by-step explanation:
y=-6x
-2x-7y=40
------------------
-2x-7(-6x)=40
-2x+42x=40
40x=40
x=40/40
x=1
y=-6(1)=-6
