Answer:
BC = 107
Step-by-step explanation:
Point B is between A and C.
AB = 3x-1
BC = 9x+8
AC = 139
We need to find BC for which we need to find x first.
<u>Finding 'x':</u>
We know that AB + BC = AC
*putting the values of AB, BC and AC*
3x-1+9x+8 = 139
12x+7=139
12x=132
x=132/12
x=11
Now, BC = 9x+8 = 9(11) +8
BC = 99+8
BC = 107
Answer:
x=8
Step-by-step explanation:
If the value of x varies directly as the value of y we can say they are directly proportional. This implies that when y increases x will increase too, and when y decreases x will also decrease.
If x=16 when y=3/4 we can write their relation as:
x/y = 16/(3/4) = 16*(4/3) = 64/3
So, for every value of y, the ratio x/y must maintain equal to 64/3 because both values are proportional.
Now we can see what happens to x when y varies. If y=3/8:
x/(3/8) = 64/3
Multiply both sides by 3/8 to eliminate the 3/8 in the denominator.
x/(3/8) * (3/8) = (64/3) * (3/8)
See that we have a 3 multiplying and another dividing, we can eliminate them.
x = 64/8
x = 8
So, if y decreases to 3/8 x will decrease to 8. Notice that y is decreasing in a half as 3/8 is the half of 3/4, and x is also decreasing in a half from 16 to 8, what makes sense.
S) This question is asking me to find the volume of the backpack.
O) Identify the facts: compartment one is 14x3x10, compartment two is 12x2x10, Julissa got a new backpack
Eliminate the unnecessary facts: Julissa got a new backpack
List the necessary facts: compartment one is 14x3x10, compartment two is 12x2x10
L) I chose Multiplication, I will multiply the measurements of compartment one, then multiply the measurements of compartment two and add them together to find the volume of the backpack.
V) I think the backpack will be at least 300 inches cubed.
(SOLVING PART)
Compartment one: 12 times 2 times 10 = 240
Compartment two: 14 times 3 times 10 = 420
420 + 240 = 660
E) Julissa’s backpack is 660 inches cubed.
I hope this helps
Answer:
12
Step-by-step explanation:
Waterfalls to Canoes = 6 units
Canoes to Fishing Area = 6 units
Total = 6+6 = 12
