3x + 1 = 8
move +1 to the other side
sign changes from +1 to -1
3x+1-1= 8-1
3x= 7-1
divide by 3 for both sides to get x by itself
3x/3= 7/3
Answer:
x= 7/3 and x= 2 1/3
Answer:
Step-by-step explanation:
15 bags for $20 can be represented with 15/20
so x bags for $4 can be represented with x/4
now if you proportion it out (ricochet), 4x15 is 60, 60 divided by 20 is 3, so you can buy 3 bags of potatoes with $4.
OR
you could do 15/20 is 0.75
0.75 times 4 is 3, so $4 can buy you 3 bags.
1. Let L=length and W=width
2. L=5w+2
3. The perimeter can be solved as follows:
(5w+2) + (5w+2) + w + w = 114 in
12w + 4 = 114 in
12w = 110
w = 110/12
w = 9.17
L = 47.83
Answer:
25in
Step-by-step explanation:
if the model is 63. 5 cm, and 2.54 cm is equivalent to 1 in
you can do 63.5 / 2.54 to get 25 in
Step-by-step explanation:
Using distance formula: { origin is (0,0)}
√(x - 0)² + (y - 0)²
√x² + y²
