Answer:
$14.60
Step-by-step explanation:
5.84 times 2.5 = 14.6
Answer:
Harriet's estimated length is between 44.1 inches and 47 inches.
Step-by-step explanation:
Let the error be x.
so, x<4%
Now, if error is 1%
45 1/2 + 1% of 45 1/2
or, 91/2 + 1/ 100 × 91/2
= 46
Now,
45 1/2 - 1% of 45 1/2
or, 91/2 - 1/100 × 91/2
= 45.1
Now,
if error is 3%
45 1/2 + 3% of 45 1/2
or, 91/2 + 3/100 × 91/2
= 47
OR
45 1/2 - 3% of 45 1/2
= 91/2 - 3/100 × 91/2
= 44.1
9/10 - 11/12
Multiply both sides to find a common denominator in this case it’s 60
54/60 - 55/60
Then the answer would be -1/60
Elimination:
3x - 9y = 3
6x - 3y = -24
3x - 9y = 3
18x - 9y = -72
(subtract)
-15x = 75
÷ -15
x = -5
(3 × -5) - 9y = 3
-15 - 9y = 3
+ 15
-9y = 18
÷ -9
y = -2
Substitution:
6x - 3y = -24
+ 3y
6x = -24 + 3y
÷ 6
x = 4 + 0.5y
3(4 + 0.5y) - 9y = 3
12 + 1.5y - 9y = 3
12 - 7.5y = 3
- 12
-7.5y = -9
÷ -7.5
y = 1.2
x = 4 + (0.5 × 1.2)
x = 4 + 0.6
x = 4.6
So this one didn't fail as much, but I got different numbers. If you have to give in values, I'd give in the values from the elimination because I don't trust myself when it comes to the substitution
