Answer:
84.5 more points
Step-by-step explanation:
85+6.5= 91.5
176-91.5= 84.5
Z= -16
first you have to subtract 7 from both sides by using inverse operation
-7 =-9
+7 =-9
the 7's cancel out and your left with (z= -9)
-7
___
z=-16

<u><em>Answer:</em></u>perimeter = 10 + </span>√10<span> units
<u><em>Explanation:</em></u><u>First, we will need to get the length of each line using the distance formula which is as follows:</u>distance = </span>

<span>
<u><em>1- length of AB:</em></u>
AB = </span>

<span> = 5 units
<u><em>2- length of AC</em></u>
length of AC is the same as AB = 5 units
<u><em>3- length of BC:</em></u>
BC = </span>

<span> = </span>√10<span> units
<u>Now, we can get the perimeter by adding the side lengths as follows:</u>perimeter = 5 + 5 + </span>√10<span>
perimeter = 10 + </span>√10 <span>units
Hope this helps :)</span>
86 in I think sorry I’m not sure
If the ratio is 4:5, then we have 4 + 5 = 9 "parts" of the ratio. What we want to do is to divide 18 by 9 to find out how many cups are in such a "part":
18 / 9 = 2
So if we know that there are 2 cups in each "part", If we want to make the ratio 4:5, all we need to do is to multiply 4 by 2 and 5 by 2:
4 * 2 = 8
5 * 2 = 10
So from 18 cups we can make two groups of 8 and 10 cups to keep the ratio of 4:5.
