Answer:
The correct factored form is (x -2)(x - 5)
Step-by-step explanation:
When looking for the numbers to go in the parenthesis, find numbers that multiply to the final term and add up to the middle term. To find these, list out the factors of 10.
1 * 10
-1 * -10
2 * 5
-2 * -5
As you can see, -2 and -5 add up to -7. So we select these to go in the parenthesis with x.
(x - 2)(x - 5)
Answer:
Step-by-step explanation:
To find x, we first have to solve the equation given in the question:
Therefore, x = 9.
Hope this helped!
Answer:
Broken = 7x
Step-by-step explanation:
Left = x
x(7x) = 30
(7x² = 30)⅐
x² = 4.285
√x² = √4.285
x = 2.07
Left = 2.07 meters
Broken = 7 x 2.07 = 14.49 meters
i hope this is correct!
good luck on ur test!
Let the hamburgers be x and cheese burgers be y.
x + y = 24
3x + 3.5 y = 79
x = 24 - y.
Substituting the value of x,
3( 24 - y) + 3.5 y = 79
72- 3y + 3.5 y = 79
72 + 0.5 y = 79
0.5y = 79 - 72 = 7
1/2 y = 7
thus, y = 7 * 2 = 14
Substituting the value for x,
x + y = 24
x + 14 = 24
x = 24-14 = 10
Thus, x = 10.
Thus, she sold 10 hamburgers and 14 cheeseburgers
From the table associated with this question.
It was seen that 75 customers purchased between 4 and 8 gallons of gasoline while 48 customers purchased between 8 and 12 gallons of gasoline.
The total number of customers who bought gasoline from the gas station on that day is 34 + 75 + 48 + 83 + 118 + 14 = 372
Therefore, the percent of customers that purchased between 4 and 12 gallons of gasoline is given by:
