Answer:
Down Below
Step-by-step explanation:
b=0.5
g=0.8
1. 3b + 5g = ?
3×0.5+5×0.8=?
1.5+4= 5.5 cm
2. 6(3b+5g) = ?
18b + 30g
18×0.5+30×0.8
9+24= 33 cm
3. 2b + 3g
2×0.5+3×0.8
1+2.4=3.4 cm
4. 7(2b+3g)
14b + 21g
14×0.5+21×0.8
7+16.8= 23.8 cm
5. Add number 2 and 4 together
14b+21g+18b+30g= 32b+ 51g
Take numbers and add them from problems 2 and 4
23.8+33=56.8 cm
Solve it like this. x + (x+1) + (x+2) + (x+3) = 286
4x + 6= 286
4x= 280
x = 70
70+71+72+73=286
25x² - 36 = 0
25x² - 30x + 30x - 36 = 0
5x(5x) - 5x(6) + 6(5x) - 6(6) = 0
5x(5x - 6) + 6(5x - 6) = 0
(5x + 6)(5x - 6) = 0
5x + 6 = 0 or 5x - 6 = 0
- 6 - 6 + 6 + 6
5x = -6 5x = 6
5 5 5 5
x = -1.2 x = 1.2

Step-by-step explanation:
"Since a 3/4 yard piece can't be cut out of a 1/3 yard-long piece, let's forget about this 1/3 yard piece"
This quote concerns me a little. There might be some left over from the 12 yard peice and together with the 1/3 yard maybe it would make another one. Of course if you looked at the left over bit afterwards this would be alright. That is probably what you were intending to do.
Otherwise it would be just
Answer:
Coefficient of x
Variable
Constant
Step-by-step explanation:
Given
Required
Complete the statements
In 3x, x is the variable; so:
Coefficient of x
In 2(x + 2), 2 is the variable so:
Variable
4 stands alone. So, it is a constant
Constant
