The two tangent lines for each circle are the same length. Set the equations to equal and solve for x.
1. 4x + 3 = 3x +12
Subtract 3x from each side:
x +3 = 12
Subtract 3 from both sides:
x = 9
2. -2 + x = 2x -7
Subtract 2x from both sides:
-2 - x = -7
Add 2 to each side:
-x = -5
Multiply both sides by -1:
x = 5
-4x-24=8
So you move the -24 to the other side.
-4x=32
Divide both sides by -4.
x=-8
It should be the first one, or 3x, I’m pretty sure because x is going to be the amount that he has and he has 3 times the amount or something
Answer:
Well I figure you would use a ratio. we are given one when comparing 240 lbs to 180 calories for each mile:
240lbs/180calories = 1 mile
we.are.given another when saying a person. burns 36 calories in 1 mile. we don't know weight so we will say x lbs:
x/36calories = 1 mile
since they both equal 1 mile we know they are equal:
240/180 = 1 = x /36
we can get rid of the 1 in between and say:
240/180 = x/36
let's reduce first fraction
8/6 = x/36
cross multiply:
8*36 = 6x
divide both sides by 6
8*6 = x
x = 48
Step-by-step explanation:
The frequency of the data sets is defined as the number of times the data is repeated in the given dataset. The frequency of the given data is calculated in the table below.
<h3>What is the frequency of the data sets?</h3>
The frequency of the data sets is defined as the number of times the data is repeated in the given dataset.
Height (cm) Frequency
146 -- 2
147 -- 1
148 -- 1
149 -- 1
150 -- 2
151 -- 1
152 -- 6
153 -- 2
154 -- 3
155 -- 1
As we can see that the height of 146 cm is repeated two times so its frequency is 2. From this concept, all the frequencies are calculated above.
