Answer:
B . 1500 children and 700 adults
Step-by-step explanation:
<h2><u>How many children and how many adults attended?</u></h2>
create an equation
make use of variables:
children --x
adults --y
1.5x + 4y = 5050
x + y = 2200
<u><em>now make use of the options given and place them into the equation .</em></u>
lets try the first one
1.5 * (700) + 4*(1500) = 7050
<h3>HENCE : A IS WRONG </h3>
lets try the second one
1.5 * ( 1500) + 4 *(700) = 5050
<h3>HENCE : B IS CORRECT..</h3>
<u>the answer is B.</u>
you can check the others if you want to , so that you are able to see if you are correct. ( optional)
Answer:
Refer to the diagram in the attachment.
Step-by-step explanation:
There are two events here: the first one is the number on the cube. The second one is the outcome of the coin toss. This tree should contain two columns, one for each event.
Start with the first column. Let 
be the outcome of the number cube. There are six possible values: 
. That corresponds to six branches, one for each outcome.
Continue to the second column. Let 
be the outcome of the coin toss. No matter which number was obtained for , there would always be two possible outcomes for
23x - 1 = 45
23x = 1 + 45
23x = 46
x = 46 : 23
x = 2
Answer: Add 5 to both sides
What is the first step needed to solve 4 over 7 the whole multiplied by x minus 5 equal negative 13?
Answer- Add 5 to both sides
(4/7)x - 5 = -13
• As mentioned above, first step would be,
adding 5 to both sides
=> (4/7)x - 5 + 5 = -13 + 5
=> (4/7)x = -8
• Now, transporting 7 from L.H.S. to R.H.S
=> 4x = -8 × 7
=> 4x = -56
• Now in the same way, transporting 4 from L.H.S. to R.H.S
=> x = (-56/4)
=> x = -14
• And in this way, or taking<u> (Add 5 to both sides)</u> as our first step, we find that the value of x is -14.
<u>∴ </u><u> </u><u>x = -14</u>
Hope it helps.
Slope intercept form is y = mx + b...ur slope will be in the m position and ur y int will be in the b position
examples : slope = 2 , (1,3)....x = 1 and y = 3
y = mx + b
slope(m) = 2
(1,3)...x = 1 and y = 3
now we sub and find b, the y int
3 = 2(1) + b
3 = 2 + b
3 - 2 = b
1 = b
so in slope intercept form, ur equation is : y = 2x + 1
================
another example : slope = 3 , (-2,-4)
y = mx + b
slope(m) = 3
(-2,-4)...x = -2 and y = -4
now sub and find b, the y int
-4 = 3(-2) + b
-4 = - 6 + b
-4 + 6 = b
2 = b
so ur equation is : y = 3x + 2
