Perform indicated multiplication on left side..

4-x+2=2x-12+3x  combine like terms on both sides

-x+6=5x-12  subtract 5x from both sides

-6x+6=-12  subtract 6 from both sides

-6x=-18  divide both sides by -6

x=3

Marta has $840 in her savings account. She earns $15 per hour working at a food truck and puts all of her earnings into the bank
Flauer [41]

Let h = the number of hours Marta works

Her savings in her account can be calculated by:

840 + 15h

This needs to be at least $2650 for her trip, so an inequality to solve:

840 + 15h ≥ 2650,  where h is the number of hours worked

Now solve:

15h ≥ 1810

h ≥ 1810/15

h ≥ 120\frac{2}{3}

Marta needs to work at least 120\frac{2}{3} hours in order to have enough money for her trip.

Find two positive even consecutive integers such that the square of the smaller integer is 10 more than the larger integer
mafiozo [28]

Answer:

the numbers are 4,6

Step-by-step explanation:

Let

x-------> the smaller even consecutive integer

x+2-------> the larger even consecutive integer

we know that

x^{2}=(x+2)+10

solve for x

x^{2}-x-12=0

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

x^{2}-x-12=0

so

a=1\\b=-1\\c=-12

substitute in the formula

x=\frac{1(+/-)\sqrt{-1^{2}-4(1)(-12)}} {2(1)}

x=\frac{1(+/-)\sqrt{49}} {2}

x=\frac{1(+/-)7} {2}

x=\frac{1(+)7} {2}=4  ------> the solution (must be positive)

x=\frac{1(-)7} {2}=-3

therefore

the numbers are 4,6

laiz [17]
First you would have to convert , so 12 inches = 1 foot . So do 12 X 16= 192inches, then subtract 192-6=186inches should be the difference IN INCHES. If you need it in feet divide 186 by 12 which should give you 15.5feet
