Answer:
The answer to your question is three numbers
Step-by-step explanation:
Data
Numbers between 1 and 40
-Divisible by 2
-Prime numbers its digits.
Process
1.- Write all the numbers divisible by 2 between 1 and 40
2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38
2.- Look for the numbers whose digits are prime numbers
2 22 32
3.- Conclusion
three numbers 2, 22 and 32
<span>-4x^2+3x+1=0
D = b</span>² - 4ac = 3² - 4 * (-4) * 1 = 9 + 16 = 25
D>0 ⇒ <span>this equation has two solutions.</span>
30= 20% of ?
30= 20/100 (x)
30= .2 (x)
x=150
150 kids are at the shcool
1) So the ratio of Machine A to B is x + 16 : x (x being the paper printed in machine b).
2) This is in 4 minutes so every minute it will be 152.
2) So x + 16 + x = 152, or 2x + 16 = 152.
3) So to find x, we can subtract 16 from both sides. 2x = 136
4) Now we just divide both sides by 2 to get x = 68.
5) So machine A will be 68 + 16 = 84.
= 84

Answer:
3
Step-by-step explanation:
let the no of people who share the meal be x
each member paid $17
total cost of meal=$51
so ur equation is
$17x=$51
x=$51/$17(here $ and $ also gets cancel)
x=3
therefore three menber shared the meal.
Note:when in multiplication when u transfers the number to other side it changes into mltiplication.For example
$17=$51
here $17 is multiplied with x and when we bring $17 to right hand side it divides $51.
