Answer:
Using division equality property to solve for b. b=27
Step-by-step explanation:
A book cost $3
Mr. Grayson spent $81 on books
Let number of books be b
Total cost invest on book = 3b
This would be equal to $81
Therefore, 3b=81
Now we solve for b
Using division method of equality
If we divide both side by same number in equality.After division we get both are equal .
3b=81
Here we divide by 3 both sides
3b÷3=81÷3
b=27
Thus, Using division equality property to solve for b. b=27

The value of
.

The value of
is 150°. ✅

We know that,

➡ 81° +
= 180°
➡
= 180° -81°
➡
= 99°
Since an exterior angle of a triangle is equal to the sum of the two opposite interior angles, we have
=
+ 51°
Substituting the value of ''
" in the above equation,
➪
= 99° + 51°
➪
= 150°

True is the answer I’m pretty sure
Answer:
g)6.88
Step-by-step explanation:
We’ll begin by finding the mean of the data set.
32+43+38+28+51=192 then 192/5=38.4
Then find the absolute value of the difference between each data value and the mean.
l32-38.4l=6.4
l43-38.4l=4.6
l38-38.4l=0.4
l28-38.4l=10.4
l51-38.4l=12.6
Lastly, find the sum of the absolute values and divide by the number of the values
6.4+4.6+0.4+10.4+12.6=34.4
34.4/5=6.88
Answer:
yes
