Answer:
Problem: 5.24 - 4.93
Step-by-step explanation:
You subtract just like a normal Addition problem however you MUST make sure the decimal point line up,...
1st: subtract the 3 from the 4 [0.01]
2nd: subtract the 9 from the 2 (make the 2 a 12 (by carrying a one from the 5 (which then becomes a 4))) [0.30]
3rd: Finally subtract the 4 from the 4,... 0
<em>Answer = 0.31,...</em>
A more summed up answer: Subtracting (and adding for that matter) decimals happens exactly like normal. However you MUST MAKE SURE that your decimal points are lined up,... if you are subtracting a 0.09 from a 4.5 and the 4.5 doesn't have a hundredths place just remember that you can add a 0 on the end (4.50) without chancing it's value. (and then just subtract like normal)
Answer:
60 cm
Step-by-step explanation:
2x the width and 2x the length gives you the perimeter. This can be represented by the equation:
2w + 2L = P
Use the information given in the word problem to fill in the variables.
2(59) + 2L = 238
118 + 2L = 238
move 118 to the other side of the equation.
2L = 238 - 118
2L = 120
move 2 to the other side of the equation.
L =
L = 60
Answer:
y=4x
Step-by-step explanation:
The equation of a line is y=mx+b, where m is the slope and b is the y intercept.
The slope formula is Δy/Δx, so using the coordinates (1, 4) and (2, 8), the slope is which equals 4.
The y intercept is 0.
Therefore, the equation is y=4x.
