Answer:
-2 * 2 = -4, and 5 * -3 = -15, so -4 + (-15) = -19
Step-by-step explanation:
Answer:
The difference between the size of white blood cells and the size of red blood cells in scientific notation is m.
Step-by-step explanation:
we are given that the size of white blood cells is 0.000012 metres and the size of red blood cells is 0.0000065 metres.
And we have to find the difference between the size of both cells in scientific notation.
SO, Size of White blood cells = 0.000012 m
Size of Red blood cells = 0.0000065 m
Now, Difference between both cell sizes = Size of white blood cells - Size of Red blood cells
= 0.000012 m - 0.0000065 m
= 0.0000055 m
Now, in scientific notation it is represented as = m
Hence, the difference between the size of white blood cells and the size of red blood cells in scientific notation is m.
Answer: he saved $15
Step-by-step explanation:
The regular price is $5.00 per rose bush, but last week they were on sale at 2 for $8.50. This means that the amount that one would cost is
8.5/2 = $4.25
If Jim bought 20 rose bushes last week, it means that the amount that he paid for 20 rose bushes is
20 × 4.25 = $85
The regular price is $5.00 per rose bush. If he had bought at the regular price, the amount that he would have paid is
5 × 20 = $100
Therefore, the amount saved by the bushes on sale is
100 - 85 = $15
x = 4.5 so it is 3/-8 = 4.5/12
