-z-28/-25=18
First, multiply both sides by -25
z-28=-450
Now just add 28 to both sides
z=-422
It will be b: (49+5)/6=n
they have asked us that the next slide will be 5 meters taller then the previous one so it will be 49+5 and to find the length n of one section we will divide it by 6 so the answer will be B:(49+5)/6=n
If you wish to<u> mentally estimate</u> the <u>total cost</u> of items, <u>rounding </u>off the items to the<u> nearest half dollar</u>, then you have to consider all five items separately.
Five items cost $1.85, $.98, $3.49, $9.78, and $6.18.
1. $1.85≈$2;
2. $0.98≈$1;
3. $3.49≈$3.50;
4. $9.78≈$10;
5. $6.18≈$6.
Then the total cost is
$2 + $1 + $3.50 + $10 + $6 =$22.50.
Answer: correct choice is C
5% of 235 is: 235*(5/100)= 235/20 = 11,75 or 5% of 470 is: 470/20 = 23,5
Total cost = 2*(235 + 11,75) = 2*246,75 = 493,5 or Total cost = 470 + 23,5 = 493,5
It’s the 31 hope this helps you
