Answer:
r = -3
Step-by-step explanation:
-18=9+9r
take 9 from both sides -27=9r
9r=-27
divide both sides by 9 r=-3
X=-6
1(x-4) over 5 =-2
Multiply all terms by the denominator to get simplified x-4=-10
Add 4 to each side to get x=-6
I would use multiplication and addition.
3 x 64 = 192
3 x 48 = 144
192 + 144 = 336 total ounces of juice.
Of the 98 butterflies cataloged, 8 were giant swallowtails. If about 5 times as many butterflies visit, we expect about 5 times as many to be giant swallowtails.
5*8 = 40
The appropriate choice is ...
A. 40
The easiest thing to do here is to split into two right triangles. The split will occur at x=1.
A= (base times height) / 2
Height of both is 3
Base of left is 6
Base of right is 3
(6*3)/2 = 9
(3*3)/2 = 4.5
Now, add together.
9 + 4.5 = 13.5 sq units
