Hours M W F = 4 hours x 3 = 13
Hours S = 8 hours
Total Hours per week = 21 hours
Total made per week = 21 x $10 = $210
Step-by-step explanation:
1.
4(3x + 2) = 4(2x + 3) + 4x do the multiplying
2.
12x + 8 = 8x + 12 + 4x export like terms to the same side of the equation and add/subtract like terms
3.
12x - 12x = 4
4.
0 = 4 this is not an equation so there's no solution to this one equation
1.
10(x + 4) - 3 = 14x + 1 do the multiplying
2.
10x + 40 - 3 = 14x + 1 export like terms to the same side of the equation and add/subtract like terms
3.
36 = 4x
9 = x there's one solution to this equation
1.
1/2 (10x + 15) - 3/2 = 2x + 6 + 3x do the multiplying
2.
(10x + 15)/2 - 3/2 = 5x + 6 export like terms to the same side of the equation and add/subtract like terms
3.
(10x + 12)/2 = 5x + 6 multiply both sides with 2 so we can get rid of fraction
10x + 12 = 10x + 12
0 = 0 there's infinetly many solutions to this equation meaning whatever number written instead of x there will a solution.
Answer:
4 + 3n
Step-by-step explanation:
Number of seed planed in his garden = 4
Let the Number of seed planted in each neighbor's garden = n
Number of neighbors he has = 3
The total number of seeds planted can be represented by the equation :
Number of seeds planted in his garden + (number of neighbors * number of seeds planted in each neighbors garden)
4 + 3n
Answer:
15 years
Step-by-step explanation:
$10,312.50-$7500 = $2,812.50 in interest we need over time
7500 x 2.5= $187.50/year (interest)
$2,812.50 / $187.50 = 15 years
