Answer: 49/387420489 P^8
Step-by-step explanation: Simplify the expression.
Remark
What you can do is solve this system of equations
Let the 2 point questions = x
Let the -1 point questions = y
Let the 0 point questions = n
2x - y = 24
x + y + n = 20 So start by letting x = 14 (just a random number) Solve the first equation.
2x - y = 24
2*14 - y = 24
28 - y = 24 Subtract 28 from both sides.
- y = 24 - 28
- y = - 4
y = 4
Now use the second equation to solve for n
14 + 4 + n = 20
18 + n = 20
n = 20 - 18
n = 2
Answer 1
<em>x = 14</em>
<em>y = 4 </em>
<em>n = 2 Total 20.</em>
This time lets try x = 15 and solve for y
2*15 - y = 24
30 - y = 24
- y = - 6
y = 6
15 + 6 + n = 20 This obviously will not work. 15 right is too many to be this circumstance. n would have to be -1 and that isn't possible.
Try x = 13
2x - y = 24
2*13 - y = 24
26 - y = 24
-y = 24 - 26
-y = -2
y = 2
Now use the second equation.
x + y + n = 20
13 + 2 + n = 20
15 +n = 20
n= 5
So Answer 2 is
<em>x = 13</em>
<em>y = 2</em>
<em>n = 5 </em>
Millie has a box of 100 cubes and a box of 70 cubes
she has 100+70 cubes together=170
She wants to make trains of 10 cubes each,
Which means,she needs to divide 170 with 10.
170/10
=17
she can make 17 trains of 10 cubes each..
How many does she have so far becase u just subtract it by that nuber
