Answer:
Markus has 6 marbles in each bag.
Step-by-step explanation:
Markus has 18 marbles and 3 bags
If you divide 18 marbles by 3 bags that would be 6 marbles in each bag.
4x+2y=10 Equation 1
x-y=13 Equation 2
Solving by substitution method.
Isolate x from equation 2.
x=y+13
Substitute value of x in equation 1
4(y+13)+2y=10
4y+52+2y=10
6y+52=10
6y=-42
y=-7
Now substitute value of y in x=y+13
x=-7+13
x=6
Answer: (6,-7)
Answer:
Given expression is equal to 1/32
Step-by-step explanation:
Given that:
= 4^(-5/2)

Answer:
- triangle
- square
- hexagon
- dodecagon
Step-by-step explanation:
The 12 points marked can be divided into this many equal-size groups:
3, 4, 6, 12
so the figures that can be constructed are ...
- triangle . . . . connects every 4th mark
- square . . . . . connects every 3rd mark
- hexagon . . . .connects every other mark
- dodecagon . . connects every mark
_____
12 is also divisible by 1 and 2, but the minimum number of vertices in a regular polygon is 3.
