Answer:
13 bottles of soap
Step-by-step explanation:
71.5/5.5=13
Answer:192
Step-by-step explanation:
Answer:
We solve the equations g + e = 117 and e / g = 2 / 7; where g = number of gas mowers and e = number of electric mowers;
So, g = 117 - e and 2g = 7e;
Then, 2( 117 - e ) = 7e;
234 - 2e = 7e;
234 = 9e;
e = 234 ÷ 9;
e = 26;
g = 117 - 26;
g = 91;

Answer:
Yes you are
Step-by-step explanation:
If you multiply the first equation by 3 , y becomes 3y and so you can eliminate from there.
The number of solutions in the equation is (b) two real solutions
<h3>How to calculate the number and type of solutions?</h3>
The quadratic equation is given as
-5x2 + 4x + 1 = 0.
Rewrite properly as
−5x² + 4x + 1 = 0
The discriminant of a quadratic equation is calculated using
d = b² - 4ac
In the equation −5x² + 4x + 1 = 0, we have
a = -5, b = 4 and c = 1
Substitute a = -5, b = 4 and c = 1 in d = b² - 4ac
So, we have
d = (4)² - 4 * (-5) * (1)
Evaluate
d = 36
Because the discriminant is greater than 0, the equation has two solutions and the type of solution is real solution
