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: 105 = g
Step-by-step explanation: To get <em>g</em> by itself, we would multiply
both sides of the equation by 7.
On the left, (7)(15) IS 105 and on the right, the 7's cancel.
So we have 105 = g.
6x + 9 < 3 3x - 8 > 13
6x < 3 - 9 3x > 13 + 8
6x < - 6 3x > 21
x < -6/6 x> 21/3
x < -1 x > 7
solution is : x < -1 or x > 7
====================
4x + 5 > 25
4x > 25 - 5
4x > 20
x > 20/4
x > 5
===================
5 - 2x > = 27
-2x > = 27 - 5
-2x > = 22
x < = -22/2
x < = -11
==================
-2 < = x - 7 < = 11
-2 + 7 < = x - 7 + 7 < = 11 + 7
5 < = x < = 18
Ok, so what you're going to do is add the -6 to the other side and combine it with the number 2 making it 8, then you are going to subtract the 5k from the left side and add it to 3k so if you now have a -5k + 3k it would = -2k then you would take the 8=-2k and divide each side by -2 which leaves you with -4=k
1.99p = x
x = total cost
1.99p = 1.99 per pound of grapes.
