Each T shirt costs $21.

Since Martha takes her niece and nephew to a concert, and she buys T-shirts and bumper stickers for them, and the bumper stickers cost $ 1 each, and Martha's niece wants 1 shirt and 4 bumper stickers, and her nephew wants 2 shirts but no bumper stickers, to determine, if Martha's total is $ 67, what is the cost of one shirt, the following calculation must be performed, posing linear equations:

  • 1 bumper sticker = $ 1
  • 1 T shirt + 4 bumper stickers + 2 T shirts = $ 67
  • 1X + 4 x 1 + 2X = 67
  • 3X = 67 - 4
  • X = 63/3
  • X = 21

Therefore, each T shirt costs $21.

A farmer plowed a rectangular section of land for a new crop. The section measures 24 1/2 yd by 38 1/2 yd. Find the total area i
MAVERICK [17]

Answer: 943\dfrac{1}{4}\text{ sq. yds}

Step-by-step explanation:

Given ,  A farmer plowed a rectangular section of land for a new crop.

Dimensions of the section is given by :-

Length by width = 24\dfrac{1}{2}\text{ yd by }38\dfrac{1}{2}\text{ yd}

Since , the area of a rectangle = length x width

Then, the total area in yards of plowed section of land will be:

24\dfrac{1}{2}\times38\dfrac{1}{2}\text{ sq. yds}\\\\=\dfrac{2(24)+1}{2}\times\dfrac{2(38)+1}{2}\text{ sq. yds}\\\\=\dfrac{49}{2}\times\dfrac{77}{2}\text{ sq. yds}\\\\=\dfrac{3773}{4}\text{ sq. yds}\\\\=943\dfrac{1}{4}\text{ sq. yds}

Hence, the total area in yards of plowed section of land =  943\dfrac{1}{4}\text{ sq. yds}

(5m 2 - 2m + 1)(3m - 4)
nirvana33 [79]
15m ^3 - 26m^2 +11m - 4 is the result of the product.

(5m^2 -2m +1)(3m-4)
On opening the bracket, we multiply the terms,
= 15m^3 -6m^2 +3m -20m^2+8m -4
= 15m ^3 - 26m^2 +11m - 4
This is the result of the product
When we mutiply the two equations.

Tony’s class needs more than $500 for the school dance. So far, they have raised $200. They plan to have a car wash, charging $8
anzhelika [568]
<h2><em><u>PLZ MARK BRAINLIEST</u></em></h2><h2><em><u></u></em></h2>

No, he is not correct for if they washed 37 cars they would have made a total of 296 dollars washing cars. Because this is an inequality, he needs to get a value equal too or greater than 300 dollars on car washes. Also, because he already has 200 dollars collected, you could write the inequality as "8x is greater than or equal to 300".
