Answer:
= 70f - 9g
Step-by-step explanation:
1. Remove parentheses
2. Multiply the numbers
3. Multiply the numbers
1762 feet would be 2 feet more. There are 5280 in a mile, divide that by three and get 1760 feet.
The other person is literally wrong. The answer is D. Supplementary because two angles that add up to 180 are supplementary angles.
Let's call the two numbers a and b. So we know that the difference of the two numbers is 36:
a - b = 36
And we know that their sum is 286:
a + b = 286
We can use either of these equations to solve for one of the variables in terms of the other variable. Let's use the first and solve for a:
a - b = 36
a = 36 + b
Now we plug this into the other equation and solve for b there:
(36 + b) + b = 286
36 + 2b = 286
2b = 250
b = 125
Answer:
Step-by-step explanation:
To find the value of x, Cramer's rule says you replace the x-coefficients with the equation constants to form the matrix whose determinant is the numerator of the fraction. The denominator is the determinant of the matrix of coefficients. The equation constants are 148 and 246, so you expect to find those in the first column of the numerator (answer choices A and C).
The calculation is carried out correctly only in answer choice A.
