1.16 rounded to its nearest tenths is 1.2.
The placevalue of a number is given as:
Example:
1234.567
1 = thousand place value
2 = hundred place value
3 = tens place value
4 = ones place value
5 = tenths place value
6 = hundredths place value
7 thousandths place value
We have,
1.16
The number 1 after the decimal point is in the tenthplacevalue.
Now,
Since 6 is greaterthan 5 tenth place value will be rounded to the next number.
So,
1.16 rounded to the nearest tenths.
= 1.2
Thus,
1.16 rounded to its nearest tenths is 1.2.

Answer:
Step-by-step explanation:
Number of pounds purchased = 1.8 pounds
Cost per pound = $5.99
⇒ Total amount spent = 5.99 × 1.8 = $10.782
10.782 × 100 = 1078.2 cents
1.8 x 5.99 = 10.782
10.782 rounded to the nearest hundredth is 10.78
so the answer is 10.78

Step-by-step explanation:
(x+2y=6 estimate the solution to the system of equations
Answer:
x=4/3; y=7/3
Step-by-step explanation:
x+2y=6,
x=6-2y.
7(6-2y)-y=7,
42-14y-y=7,
15y=35,
y=7/3.
x+2y=6,
x+2*7/3=6
x=4/3
∴x=4/3, y=7/3.
To estimate the solution to the system of equations (7x-y=7) and (x+2y=6), we can use the method of substitution. The estimated solution is x = 1.46 and y = 2.27.
To estimate the solution to the system of equations (7x-y=7) and (x+2y=6), we can use the method of substitution. We can solve one equation for one variable and substitute it into the other equation. Let's solve the second equation for x: x = 6 - 2y.
Substituting this value of x into the first equation, we get:
7(6 - 2y) - y = 7
42 - 14y - y = 7
41 - 15y = 7
-15y = 7 - 41
-15y = -34
y = -34 / -15
y = 2.27
Now, substitute this value of y back into the second equation to find x:
x + 2(2.27) = 6
x + 4.54 = 6
x = 6 - 4.54
x = 1.46
Therefore, the estimated solution to the system of equations is x = 1.46 and y = 2.27.
