D. 1
Step-by-step explanation:
7,491 times 19 yields 142, 329
Answer:
- C. No. Vinay also multiplied the right-hand side of the equation by --5, which is incorrect.
Step-by-step explanation:
<u>Proper application of the property:</u>
- - 5(m - 2) - 25 = -5m - 5(-2) - 25 = -5m + 10 - 25 = -5m - 15
Vinay multiplied 5 and 25 as well, which is incorrect.
Correct answer choice is C.
Proportions are the comparison of two equal ratios. Therefore, proportional relationships are relationships between two equal ratios. So yes, it does matter.. I<span>nterval: all the numbers between two given numbers.</span>
1) 9x + 2 = x + 5 ---> 9x + 2 = 6
subtracted X from one side but not the other
2) 3(x-4) + 5 = 12 ---> 3x + 4 + 5 = 12
didn't distribute correctly: 3(x-4)
multiplied the X by 3 but not the -4
If you factor the equation you can see what the solutions are. Two factor a quadratic of the form ax^2+bx+c, find two values which satisfy two conditions...
jk=ac=-15 and j+k=b=-2 so j and k must be -5 and 3 so the factors are:
(x-5)(x+3)
So the other solution is x=5
