Number of people donated blood with type A, y

=\frac{28}{100}\times x\\=\frac{28}{100} \times 300\\=84

Number of people donated blood with type B, z

=\frac{20}{100}\times x\\=\frac{20}{100} \times 300\\=60

⇒Number of people with Type A blood donated more than those with Type B blood= y-z=84-60= 24

Pleaseeee answer correctly <br> Will mark Brianliest !!! HELP !
Paha777 [63]

Answer: 11

The code would print 11 as x=x-4 basically sets x to what x was and subtracts it by 4 which means 15 was its previous value and it takes 4 away from it so it is now 11. Then because the loop condition is x=11 the loop condition has been met and will now go and display x.

What is the value of x? <br><br> Enter your answer in the box.<br><br> x =___
Zanzabum

Answer:

x = 12

Step-by-step explanation:

The diagram shows an equilateral triangle (because all angles are congruent). All sides in equilateral triangle are congruent, so

4x-10=5x-22=3x+2

Solve the equation

4x-10=5x-22\\ \\4x-10-4x=5x-22-4x\\ \\-10=x-22\\ \\-10+22=x-22+22\\ \\12=x

Check this value:

4x-10=4\cdot 12-10=48-10=38\ units \\ \\5x-22=5\cdot 12-22=60-22=38\ units\\ \\3x+2=3\cdot 12+2=36+2=38\ units

Thus, x=12
