Answer:

43. 171 × $4.50 = $769.50

(171 ÷ 9) × 2 = 38

38 × $7.25 = $275.50

$769.50 + $275.50 = $1,045.00

$1,045.00 × 1.04 = $1,086.80

Answer: $1,086.80 for museum tickets and parking

171 + 38 = 209

209 × $6.00 = $1,254.00

$1,086.80 + $1,254.00 = $2,340.80

Answer: $2,340.80 for the total budget

44. Equation: 2a + 10 = 70

2a + 10 = 70 (subtract 10 from each side)

2a = 60 (divide each side by two)

a = 30

Answer: 30 envelopes

45. Inequality: $2.20x + $2.40 < $9.00

$2.20x + $2.40 < $9.00 (subtract $2.40)

$2.20x < $6.60 (divide by $2.20)

x < 3

Answer: x < 3

46. 3 inches in 4 minutes

3 ÷ 4 = 0.75

Answer: 0.75 inch(es) per minute

The only time Landon's elevation changed was from minutes 4 - 10 and 14 - 18. We know that Landon's elevation changed the fastest between minutes 14 - 18, because this occurred over the shortest period of time.

Please help i don't understand
alexira [117]

Answer:

A

Step-by-step explanation:

The diagonals of a parallelogram bisect each other. Hence, the two shorter sides created on diagonal RT ("6x-7" and "x+28" ) are equal.

<em>We can set them equal and solve for x:</em>

<em>6x-7=x+28\\6x-x=28+7\\5x=35\\x=\frac{35}{5}\\x=7</em>

<em />

<em>So the side length of 6x -7 is:</em>

<em>6(7)-7 = 35</em>

<em>and the side length of x + 28 is:</em>

<em>7 + 28 = 35</em>

<em />

<em>THus, the diagonal RT = 35 + 35 = 70 units</em>

<em />

<em>Answer choice A is right.</em>
