Jerry needs 216 posts to build a fence. He has 88 posts and needs P more. Write an equation that you could use to find the numbe

devlian [24]

Answer:

P = 128 Post

Step-by-step explanation:

Total post needed = 216 posts

Number of post Jerry has = 88 posts

Number of posts jerry still needs = P

Total = Number of post Jerry has + Number of posts jerry still needs

216 = 88 + P

216 - 88 = P

128 = P

P = 128 Post

The mean of 100 numerical observation is 51.18 what is the value of the sum of all 100 numbers

malfutka [58]

The "mean" is the same thing as the "average".

To get the average, you add up all the numbers on the list,
then divide the big sum by the number of items on the list.

If there are 100 numbers on the list, then in order to find their average,
you would add up all 100 numbers, then divide the big sum by 100.

If you wound up with an average of 51.18, then you must have had
5,118 just before you divided it by 100. So the big sum is 5,118.

Can someone plz help me ASAP??? my hw in hard and I don't get it

Answer:

see attachments

Step-by-step explanation:

These are "one-step" equations.

To solve the ones involving addition or subtraction, identify the constant on the same side with the variable. Add its opposite to both sides.

To solve the ones involving multiplication or division, identify the coefficient of the variable. Multiply both sides by its reciprocal (or, equivalently, divide by that coefficient).

Here are more details for the problems on the first page.

w +8 = -3 ⇒ w = -3 -8 = -11
z +(-7) = -20 ⇒ z = -20 +7 = -13
1/5x = 11 ⇒ x = 5·11 = 55
1u = -88 ⇒ u = -88/11 = -8
1/9y = -2 ⇒ y = 9(-2) = -18
12 +n = 7 ⇒ n = 7 -12 = -5
q +(-4) = 8 ⇒ q = 8 +4 = 12

The second page is solved the same way. It is shown in the second attachment.
