- |Absolute Value| - makes any negative number positive
Step-by-step explanation:
<u>Step 1: Define</u>
-3|5 - s³| + 3t
s = 2
t = 1.5
<u>Step 2: Evaluate</u>
- Substitute in variables: -3|5 - 2³| + 3(1.5)
- |Absolute Value| Exponents: -3|5 - 8| + 3(1.5)
- |Absolute Value| Subtract: -3|-3| + 3(1.5)
- Absolute Value: -3(3) + 3(1.5)
- Multiply: -9 + 4.5
- Add: -4.5
Answer:
No
Step-by-step explanation:
The first nine in on the place of the thousands, while the second nine is on the place of the tens. so the first nine is a hundred times as great as the second nine
Answer:1968ft^2
Step-by-step explanation:
Perimeter(p)=178feet
P=2L+2w
178=2L+2w
178=2(L+w)
L+w=178 ➗ 2
L+w=89.............(1)
W+7=L
L-w=7...................(11)
L+w=89... ..........(1)
L-w=7...................(11)
Subtract (11) from (1)
2w=89-7
2w=82
w=82 ➗ 2
w=41 width=41feet
Substitute w=41 in (11)
L-w=7
L-41=7
L=7+41
L=48feet
Area= length x width
Area=48 x 41
Area=1968ft^2
Answer:
-20
Step-by-step explanation:
For this, you have to calculate the Unit value,
Unit value of 1rst one, 4.99/6 = 0.83
Unit value of 2nd one, 7.99/10 = 0.79
As, 2nd one is cheaper, so it is better :))
