We will solve the problem for both cases:
Case 1:
If the amount increases by 7% we have the number for which we are going to multiply is given by:
Case 2:
If the amount decreases by 7% we have the number for which we are going to multiply is given by:
Answer:
single multiplier you would use for each case is:
x = 1.07 (increase)
x = 0.93 (decrease)
Answer:
Step-by-step explanation:
Solving an inequality is similar to solving an equation. To solve for r, isolate it. Whatever you do to one side, do to the other. Remember that a negative and a negative equal a positive, thus one side of the inequality becomes r + 5. Then, subtract both sides by -5 to find the answer.
Answer:
672
Step-by-step explanation:
anything lower then 5 or in this case 50 would round down so 649 rounds to 600 anything higher would round up 672 to 709 763 to 800 and 751 to 800
The answer is
a) 11/15
b) 1/18
Step-by-step explanation:
the area is
length × width
(3x - 2) × width = 9x² - 4
to find width we could do a real polynomial division or simply recognize the fact that
(a + b)(a - b) = a² - b²
and we see that in our area calculation we are missing the (a + b) factor.
so, width = (3x + 2)
but if you want the division :
9x² - 4 : 3x - 2 = 3x + 2
- 9x² - 6x
-----------------
0 6x - 4
- 6x - 4
----------------------
0 0
again, width = (3x + 2)
