Answer:
-2k + 6
hope its right
-2k - (-5) + 1
You should always switch the signs to their opposites if you're mutiplying a negative such as the - (-5) Hope I make sense
-2k + 5 + 1
-2k + 6
solution is (4, - 7 )
given the equations
y = 2x - 15 → (1)
4x + 3y = - 5 → (2)
substitute y = 2x - 15 into (2)
4x + 3(2x - 15) = - 5
4x + 6x - 45 = - 5
10x - 45 = - 5 ( add 45 to both sides )
10x = 40 ( divide both sides by 10 )
x = 4
substitute x = 4 into (1) for corresponding value of y
y = (2 × 4 ) - 15 = 8 - 15 = - 7
solution is (4, - 7 )
For this fraction, you would have to see how many times 7 goes into 47. So, 6 times as 7 times 6 is 42. Subtract 42 from 47, and this would be your remainder:
6
If 8= 538 Ib. then take the (538) and divide that by 8. <---- 8 for the 8 uniforms.
Your math should look like this: 538/8= about 67 pounds.
Then do 67*8= 536. (You started at 532 Ib.) this is just 2 pounds off*
So, your answer should be *67* pounds.
*Use paper and a pencil! Sometimes doing mental math can be challenging with a problem like this. So use paper and a pencil, checking your answer wont hurt either!*
