If 21 is added to a number, the result is 41 less than twice the number. Find the number.

Mathematics

TEA [102]2 years ago

Answer: 62

Step-by-step explanation: Set up your equation

  1. 21+x=2x-41 because the number (x) that 21 is added to is 41 <em>less than</em> (so subtraction) <em>twice </em>(so multiply the number x by 2) the number (x).
  2. Get the x's on one side by subtracting the single x
  3. 21=x-41
  4. Now add 41 to both sides to completely isolate x
  5. 62=x
  6. So, your answer is x=62. The number is 62.

Check your work. 62+21=83. 2(62)= 124. 124-41=83. Both equations equal 83, so the solution is correct.

Work out the value of each expression, when r= 2.5 and t = 6.
Usimov [2.4K]

Answer:

a)  4(t - r) = 4(6 - 2.5) = 4 x 3.5 = 14

b)  4t - r = (4 x 6) - 2.5 = 24 - 2.5 = 21.5

c)  2(3t - 10) = 2(3 x 6 - 10) = 2(18 - 10) = 2 x 8 = 16

d)  (t - 2)² = (6 - 2)² = 4² = 4 x 4 = 16

e) cannot decipher the equation

f)  6r + t = 6 x 2.5 + 6 = 15 + 6 = 21
