65 = 12.1+h the flower is 65 inches. it has grown 12.1 inches since the last time he measured it. the last time he measured it, it was height h.

65 = 12.1 + h

subtract 12.1 from both sides

65-12.1 = 12.1 + h- 12.1

52.9 = h

The last time he measured it it was 52.9 inches

Answer:

$\frac{5}{4} x - 2 = \frac{3}{2} x-4$

Step-by-step explanation:

$\frac{5}{2} x +\frac{7}{2} =\frac{3}{4} x+14 \\\frac{5}{2}x -\frac{3}{4} x=14-\frac{7}{2} \\\frac{10-3}{4} x =\frac{28-7}{2} \\\frac{7}{4} x =\frac{21}{2} \\x = \frac{21}{2} * \frac{4}{7} = 6 \\$

$\frac{5}{4} x -9 = \frac{3}{2} x-12 \\\frac{5}{4} x - \frac{3}{2} x= -12 + 9 \\\frac{5-6}{4} x = -3 \\\frac{-1}{4} x = -3 \\x = -3 * -4 \\x = 12$

$\frac{5}{4} x-2=\frac{3}{2} x-4 \\\frac{5}{4} x-\frac{3}{2} x=-4+2 \\\frac{5-6}{4}x=-2 \\\frac{-1}{4} x = -2 \\x = -2 * -4 \\x = 8$

$\frac{5}{2} x -7 = \frac{3}{4} x+14 \\\frac{5}{2}x -\frac{3}{4} x=14+7 \\\frac{10-3}{4} x =21 \\\frac{7}{4} x =21 \\x = 21 * \frac{4}{7} = 12 \\$

You could also replace x for 8 in every equation and see if both sides give the same answer

rosijanka [135]

Let x be the value of the his purchases without the discount. The $64 is the value of the 32% discount.
64 = 0.32x ; x = 200
Thus, he should have paid $200 if there was no discount. The amount he paid (p) is only 68% of this value. p = (0.68)(200) = 136. Hence, he paid only $136.

Answer:

$y = \frac{12}{11}x + \frac{15}{11}$

Step-by-step explanation:

so first we find the slop of the line from the given two points (10,3) and (-1,-9),

y2-y1/x2-x1 = m;

3--9/10--1 = 12/11 = m or slope

since (7,9) is parallel to this line it has the same slope.

y-9/x-7 = 12/11

$y = \frac{12}{11} x + \frac{15}{11}$
