There are no parentheses or exponents, so the Order of Operations tells you to start by performing division and multiplication left to right.
7-3+4÷2×6
= 7-3+2×6
= 7-3+12
After you have done that, you perform addition and subtraction left to right.
= 4 +12
= 16
______
A Google or Bing search box will evaluate expressions such as this according to the order of operations.
Using Substitute method:
Replace y value of equation 2 into equation 1:
4x + (x+6) = 1
Solve for x:
4x + x + 6 = 1
5x = 1 - 6
5x = -5
x = -5/5
x = -1
Pick any of the two equation, replace x with it's value -1 and solve for y:
y = (-1) + 6
y = -1 + 6
y = 5
Solution: (-1, 5)
Answer:
7/12
Step-by-step explanation:
To subtract fractions, you must make all of the fractions have a common denominator. We can set both of the denominators as 12. To achieve this, you must multiply both sides of 2/3 by 4. This will change the denominator of the fraction, while keeping the fraction equal to 2/3. Doing this will give us 8/12. Now we can subtract. Since the denominators are the same, we only subtract the numerators. Since 8-1 is 7, our answer is 7/12. The denominator does not change.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Number of 8 pounds before boxes to be removed from cargo = b
Weight in pound of crate to be loaded into cargo = 600 pounds
To achieve a balance , no more Than 400 pounds may be taken off the plane
Hence,
Number of pounds removed must not be more than 400 pounds
(8 pounds * b) ≤ 400
8b ≤ 400
Divide both sides by 8
b ≤ 50
