Answer:
1. [-1,10]
[-3, 9]
2. [-1, 5]
[-12,20]
3. [-6,15]
[-13,19]
4. (I cant read)
5. [30]
6.[20,-10]
[-20,10]
Step-by-step explanation:
P=number of pens
h=number of highlighters
p+h=8
1.09h+0.69p=752
p+h=8
minus h from both sides
p=8-h
sub that for p
1.09h+0.69(8-h)=7.52
1.09h+5.52-0.69h=7.52
0.4h+5.52=7.52
minus 5.52 from both sides
0.4h=2
divide both sides by 0.4
h=5
sub back
h=8-p
5=8-p
minus 8 frm both sides
-3=-p
mltiply both sides by -1
3=p
3 pens you bought
The answer would be as follows:
h=1.6a
with "h" representing the plant's height and "a" representing the plant's age.
(Same formula written out)
The plant's height=1.6(the plant's age
it would be about 51 or 52 percent exact but if you have to round about 50 percent was taken off the shirt.
EXPLANATION: 39 times 0.5 = 19.5
39- 19.5 = 19.50
HOPE THIS HELPS
Please take a photo of this problem... it looks very hard when it is written in the way you did.
