Answer: B
Step-by-step explanation:
4(x+3)+2x=6(x+2)
4x+12+2x=6x+12
6x+12=6x+12
12=12
All real solutions
5+2(3+2x)=x+3(x+1)
5+6+4x=x+3x+3
11+4x=4x+3
11=3
No solution
Answer:
45 total washers
Step-by-step explanation:
Looking at the ratio of 4:11:9:6, we know that there are,
4 nails in each tool box
11 screws in each tool box
9 washers in each tool box
6 brackets in each tool.
Given that there are 5 carpenters with identical tool boxes, we can find the total amount of washers by multiplying the amount of washers in each box with how many carpenters there are.
9 * 5 = 45
Answer:
Running a personal computer doesnt use alot of electricity , so it wouldn't cost very much.
6 x 13/3=
78/3
divide top and bottom by 3
26/1
26
Y = 9x
y = 5x + 24
9x = 5x + 24
9x - 5x = 24
4x = 24
x = 24/4
x = 6
y = 9x
y = 9(6)
y = 54
solution (6,54)....x = 6 and y = 54
