Answer:
≈ 8.5 hours
Step-by-step explanation:
Temperature rise is
Total temperature rise is
Time = 20.46/2.4 = 8.525 hours ≈ 8.5 hours
The value of the product of the given equation remain the same while the order is reversed
The number sequence 4 × 6 = 6 × 4 is an example of the commutative property of multiplication
Reason:
The given number sentence is 4 × 6 = 6 × 4
Required: The property the number sentence is an example of (represent)
Solution:
The difference between the left and right expression is that the order of the
values being multiplied is changed or reversed (commute)
Therefore, the number sentence states that the value of the multiplication
of two variables remain equal when the places of variables are
interchanged as follows; a × b = b × a
a × b = b × a is an example of commutative property of multiplication
Therefore;
4 × 6 = 6 × 4 is an example of the commutative property of multiplication
Let x = baby dinosaurs
y = adult dinosaurs
equation 1
total paintings = 15 painting x + 7 paintings y
equation 2
baby dinosaurs = 3 times adult
x= 3y
substitute x= 3y to equation 1
y = 4
x = 12
There are 12 baby dinosaurs and 4 adult dinosaurs in a herd with 208 total paintings
Answer:
£4 and £6
Step-by-step explanation:
Let the common multiplier of the given ratios be x.
So, 2x and 3x are the two parts of £10.
Hence,
2x + 3x = 10
5x = 10
x = 10/5
x = 2
2x = 2*2 = 4
3x = 3*2 = 6
Hence, the two parts of £10 are £4 and £6.
What are you solving for? For y: y=x or for x: x=y
