Answer:
d=-5
Step-by-step explanation:
5/8(16+24)=6(d-1)+1
distribute 5/8 into (16d+24) and 6 into (d-1)
10d+15=6d-6
subtract 6d on both sides
10d-6d+15=-6
combine like terms
4d+14=-6
subtract 14 on both sides
4d=-20
divide both sides by 4
d=-5
hope this helps

(Remember that )
4,000 cm to m:
700 cm to m:
You can observe in the figure that it is formed by two rectangles and a semi-circle.
To calculate the perimeter, you need to add the exterior measures of each figure.
Remember that the circumference of a circle is:
Where "r" is the radius
Therefore, the perimeter is:
To find the area of the indoor sports exhibition, you need to add the areas of the rectangles and the area of the semi-circle.
The area of a rectangle can be calculated with:
Where "l" is the lenght and "w" is the width.
The area of a semi-circle can be calculated with:
Where "r" is the radius.
Then, the area of the indoor sports exhibition is:
Answer:
Multiply the divisor and dividend by
✔ 100.
The new division problem becomes
✔ 4,860 ÷ 15.
The quotient of 48.6 ÷ 0.15 is
✔ 324 .
Estimating to check, you get
✔ 5,000 ÷ 15 = 333.33.
