This division question is asking how many 1/4 you can fit into 50 1/2.
We can fit 4 of them into 1 whole (4 x 1/4 = 1)
We can fit 8 of them into 2 wholes (8 x 1/4 = 2)
and so on.
But we have 50 1/2 wholes, so we would need 50 1/2 x 4.
The new number sentence is 50 1/2 x 4.
Answer:
15x^3y
Step-by-step explanation:
60, 45 & 75 are all divisible by 15
It's not a rational number because it's a continuous decimal. A rational number has an end.
Answer:
x=2 and y= -3
Step-by-step explanation:
This is a simultaneous equation. To solve this type of equation, there are three methods; substitution, Elimination and Graphical.
But here, we would be using the substitution method.
3x-y=9 Equation 1
2x-y=7. Equation 2
Getting y from equation 2, we have
-y= 7-2x
Multiply both sides by -
y= 2x-7 Equation 3
Substituting y for 2x-7 in equation 1, we have
3x- (2x-7)=9
3x-2x+7=9
x+7=9
x=9-7
x=2
Substituting x as 2 in equation 3
y=2x-7
y= 2(2)-7
y= 4-7
y= -3
