Answer:

a = -8

Step-by-step explanation:

-5⁄2 a + 5 = 25

Subtract 5 from each side

-5⁄2 a + 5-5 = 25-5

-5/2 a = 20

Multiply each side by -2/5 to isolate a

-2/5 * -5/2 a = -2/5 *20

a = -8

Answer:

1. 16π

2. 112π

3. 351.68

Step-by-step explanation:

Substitute...

=16π

To find the how much fluid it can hold, just basically find its volume. To do that, you mutiply the area of the base by the height. So...

16π*7=122π

You then just subsitute π by 3.14 so...

122(3.14)=351.68

Answer:

<h2>Total yards of ribbon bought is 6.993yards of ribbon</h2>

Step-by-step explanation:

Total pieces of ribbon James bought for his craft project = 10pieces. If each pieces of ribbon were 2.1feet long, the total number of feet for 10ribbons is expressed as;

= 10 * 2.1\\= 21feets

Converting 21 feets to yards;

1 feet = 0.333yard

21feets = x

x = 21feet * 0.333\\= 6.993yards

Total yards of ribbon bought is 6.993yards of ribbon
