Answer:
1000.
Step-by-step explanation:
We need 4 weights where 3 of them add up to
900, 1400, 1600 or 1800g.
Not sure of the method for doing this!
Lets assume that the answer is 1000 g.
Then the 3 that make 1800 could be
1000 500 and 300
- then to make 900 we need a 100g tomato giving:
1000 500 300 and 100 grams
So the 1400 will be the 1000, 300 and 100 tomato
and the 1600 will be 1000, 500 and 100.
That seems to fit !!
Answer:
calls first evening = 26
calls second evening = 80
calls third evening = 20
Step-by-step explanation:
Let x = calls third evening
x+6 = calls first evening
4x = calls second evening
x+6 + 4x + x = total calls = 126
Combine like terms
6x+6 = 126
Subtract 6 from each side
6x =120
Divide by 6
6x/6 =120/6
x = 20
x+6 = calls first evening = 20+6 = 26
4x = calls second evening = 4*20 = 80
Let x = calls third evening = 20
Plot the given point B(3,5) and a vertical line through it:
Next draw several possibilities for A(x,3), for instance
A(-4,3), A(-1,3), A(1,3), and A(5,3
Draw a line through them:
Now you can see that the only value of x is the value where the
blue line crosses the green vertical line, which is at A(3,3)
could you mark Brainy PLS
First you must set f (x) =15:
15 = 2x - 5
Now you must solve like a normal equation:
15 = 2x - 5 )+5
20 = 2*x ):2
10 = x
ANSWER: The value of x is 10
Mixed number=natural number+fraction
1+1+1=
1+2/3+1/3+1=3
1+2/3+1+1/3=3
1 and 2/3 plus 1 and 1/3
2 possible mixed numbers are 1 and 2/3 and 1 and 1/3
also 1 and 1/2 and 1 and 1/2
