Answer:
21
Step-by-step explanation:
In the given number 9261, the second group of 3 digits from the right is 009. This number lies between two perfect cube numbers 8 and 27 i.e. 23 and 33. Because 9 is more close to 8 i.e. 23, the ten's digit of the cube root of 9261 is 2. The cube root of 9261 found using the estimation method is 21.
Answer:
Y=-5/3x-1
y=2/3x-8
If you are adding then it is:
7x=21
x=3
Step-by-step explanation:
5x+3y=-3
3y=-5x-3
y=-5/3-1
2x-3y=24
-3y=-2x+24
y=2/3x-8
Answer:
length = cm
Step-by-step explanation:
Perimeter is the sum of the length of all of the sides of a figure. A rectangle has 2 pairs of sides with equal length, which is a 4 sides. Two of those sides have the measure of the width and the other 2 sides have the measure of the length. Since we know the width is , we can multiply that value by 2 (since 2 of the sides are long) and subtract it from the perimeter, 13:
The sum of the 2 sides that have the measure of the length is cm. To find the length, divide the measure by amount of sides:
÷ 2 =
The length is cm.
