Select all of the expressions that are equivalent to
-4.5 – 5.2.

Answers

Answer:

-4.5-5.2 and -4.5+(-5.2)

Step-by-step explanation:

Final answer:

The expression -4.5 – 5.2 is a simple subtraction problem involving real numbers. To find equivalent expressions, you perform the subtraction which results in -0.7. Hence, any expression that evaluates to -0.7 is equivalent to -4.5 – 5.2.

Explanation:

The expression -4.5 – 5.2 is a simple subtraction problem involving real numbers. To find an equivalent expression, we need to perform the subtraction. Here's how you do it:

First, line up the numbers vertically. -4.5 on the top and 5.2 below it.
Then subtract each number as if it were a positive value without considering the signs (5.2 - 4.5 = 0.7).
Finally, assign the sign of the largest absolute value to the result. Since the larger number 5.2 is subtracted, the result is negative. Therefore, the final result is -0.7.

Thus, the expressions equivalent to -4.5 – 5.2 are those that evaluate to -0.7.

Answers

Answer:

$BE=12 units$

Step-by-step explanation:

$We\ know\ that,\nIn\ a\ rectangle\ all\ diagonals\ are\ equal\ and\ bisect\ each\ other.\nHence,\nIn\ Rectangle\ ABCD,\nAE=EC\nHence,\nSubstituting\ the\ values\ we\ get:\nx+4=3x-12\nHence,\n-2x=-16\nx=(-16)/(-2)=8\nNow,\nWe\ also\ know\ that,\n AC=DB\nHence,\n(AC)/(2)=(DB)/(2) \nHence,\nDE=EB=AE=EC\nHence,\nSince\ AE=BE,\nBE=x+4\nWe\ already\ know\ that\ x=8.\nHence, BE=8+4=12$

Kelly is saving her money to buy a car. She has $250, and she plans to save $75 per week from her job as waitress.a. Model the situation using an arithmetic sequence.

b. How much will kelly have saved after 8 weeks?

c. If the car costs $2000, how long will it take her to save enough money at this rate?

Please someone help me.

Answers

so she is essentially saving 250+n*75, where n is the number of weeks.

after 8 weeks she will have 250+8*75, (you need to substitute n for the number of weeks, which is 8)

which is
250+600=850

how many more does she need for a car?
she is still missing 2000-850, that is 1150. divide it by 75: it's a little more than 15: so she actually needs to save for 16 weeks after she's been saving for 8, that's a total of 24 weeks.

so in total it will take her 24 weeks (and she will have a little extra).

Esther starts at one corner of a square field and walks 90 feet along one side to another corner of the field. She turns 90° and walks 70 feet, and then walks straight back to where she started. What is the area of the part of the field she walked around?a. 3150 ft²
b. 4900 ft²
c. 6300 ft²
d. 8100 ft²

Answers

Since it is a square field and she walked from one corner to another, each side of the square filed is 90 feet.
Since she walked 70 feet and then straight back to where she started, she has formed a triangle, the legs are 90 and 70 and the hypotenuse (the distance back to the start) is not needed to solve this problem.
So we have a triangle whose length is 90 and whose height is 70
A = $(1)/(2)$ bh or in this case $(1)/(2)$ (90) x (70) or 1/2 of 6300. Answer a. 3150 ft² is half of 6300 and is the correct answer
