Step-by-step explanation:
To find how many pennies are in the bigger jar if the smaller jar contains 133 pennies and the bigger has 1 2/7 of it, we have to multiply 133 by 1 2/7.
133 * 1 2/7 =
= 133 * 9/7 =
= 19 * 9 =
= 171

Answer:
The amount in dollars of wheat saved by the first operator is;
Explanation:
Given that Peter hired two combine operators to harvest his 260 acres of wheat.
And it yeilds 50 bushels per acre.
The total amount of bushels of wheat on the field is;
Since each operator harvest the same amount;
If operator 1 loss 3%, the remaining amount is;
Operator 2 loss 5%, the remaining amount is;
The amount of bushels save by the first operator compared to the second operator is;
if wheat is sold for $11.97 per bushel, the amount in dollars of wheat saved by the first operator is;
The amount in dollars of wheat saved by the first operator is;
The solution to the system of equation is (2, 7)
<h3>System of equation</h3>
Given the system of equation expressed as:
3x – y = -1 * 2
x – 2y = -12 * 1
________________
6x – 2y = -2
x – 2y = -12
Subtract to have;
6x-x = -2-(-12)
5x = 10
x = 2
Substitute x = 2 into 2 to have:
2 - 2y = -12
-2y = -14
y = 7
Hence the solution to the system of equation is (2, 7)
