Answer:
<u>Yes</u>
- (2 · x) + (2 · 7) = 36
- x + 7 = 18
- 2x + 14 = 36
<u>No</u>
- 2x + 7 = 36
- 2(x + 7) = 72
- x + 14 = 36
Step-by-step explanation:
It is appropriate to eliminate parentheses as a first step. This can be done using the distributive property, resulting in either of ...
- 2x +2·7 = 36
- 2x +14 = 36 . . . . . 2·7 evaluated mentally
or by dividing the equation by the factor outside parentheses, resulting in ...
___
Any of the equations other than these represent violations of the equal sign. Something has been done to one side of the equation without the same thing being done to the other side.
Answer:
The answer would be (3,-4)
Step-by-step explanation:
All you would do is flip the point over the y axis which gives the new point (3,-4)
Twelve hundred-thousandths is<u> </u><u>ten thousandth greater </u><u> </u> than twenty millionths
Step-by-step explanation:
We subtract the two fractions;
twelve hundred-thousandths – 12/100,000
twenty millionths – 20/1,000,000
We begin by finding the LCM of 100,000 & 1,000,000 which is 1,000,000. Then;
12/100,000 – 20 / 1,000,000 = (120 - 20)1,000,000
= 100/1,000,000
= 1/10,000
Answer:
15,000cm^2
Step-by-step explanation:
Given data
Dimension of a card
Length= 15cm
Widht= 10cm
Area= 15*10= 150cm^2
Now if 1 card covers area of 150cm^2
the 100 cards will cover x
cross multiply
x= 150*100
x= 15,000cm^2
Hence the total area covered is 15,000cm^2
