Answer:
C
Step-by-step explanation:
change decimetres into metres
length - 7.3m
Width - 4.2m
to find an area, do length times width
7.3 x 4.2 = 30.66 square metres
I hope this helped :)
Answer:
y=25x
Step-by-step explanation:
It is a linear equation with a slope of 25
If you are given y = (-3/7)x - 2 and you want it in the form Ax+By = C, then...
y = (-3/7)x-2
7*y = 7*( (-3/7)x-2) ... multiply both sides by 7
7y = -3x-14 ... distribute and multiply
7y+3x = -3x-14+3x ... add 3x to both sides
3x+7y = -14
The standard form equation is 3x+7y = -14
For example if we have 7/10 we have one 0 in the denominator so we move the decimal spot 1 to the left
So:
7.0 becomes 0.70 or .7
To make a decimal into a fraction:
0.32
Just add two zeros to the right and that means 2 0's will be added in the denominator
so:
0.32
32.0/100 or 32/100
Hope that helps :)
