The solution is B = 43
Step-by-step explanation:
Simplify and solve for the unknown for 5(B + 3) = 4(B - 7) + 2B
- Simplify each side
- Add the like terms in each side if need
- Separate the unknown in one side and the numerical term in the other side to find the value of the unknown
∵ 5(B + 3) = 4(B - 7) + 2B
- Multiply the bracket (B + 3) by 5 in the left hand side and multiply
the bracket (B - 7) by 4 in the right hand side
∵ 5(B + 3 ) = 5(B) + 5(3) = 5B + 15
∵ 4(B - 7) = 4(B) - 4(7) = 4B - 28
∴ 5B + 15 = 4B - 28 + 2B
- Add the like terms in the right hand side
∵ 4B + 2B = 6B
∴ 5B + 15 = 6B - 28
- Add 28 to both sides
∴ 5B + 43 = 6B
- Subtract 5B from both sides
∴ 43 = B
- Switch the two sides
∴ B = 43
To check the answer substitute the value of B in each side if the two sides are equal then the solution is right
The left hand side
∵ 5(43 + 3) = 5(46) = 230
The right hand side
∵ 4(43 - 7) + 2(43) = 4(36) + 86 = 144 + 86 = 230
∴ L.H.S = R.H.S
∴ The solution B = 43 is right
The solution is B = 43

Answer:
Let the first angle be x .
According to question,
second angle = x+40
then,
x+x+40 = 90
2x = 90 - 40
2x = 50
x = 25
first angle =x=25
second angle=x+40= 65

Answer: Choice number three is the correct choice: slope = –2, y-int = 4
Explanation: Slope-intercept form, y=mx+b, of linear equations, emphasizes the slope and the y-intercept of the line. In this case, number 4 is considered b in this equation which makes it the y-intercept. Remember that the number with the x in an equation such as this is the slope.

Answer:
6 begonias
Step-by-step explanation:
If there are twelve flowers in each vase
1st vase=9 daffodils+3 begonias
=12 flowers
2nd vase=twice as many begonias
If the florist put twice as many begonias in the 2nd vase, this could mean she put twice as many begonias in the 1st vase
Which is,
2 × 3 begonias in the 1st vase
=6 begonias
Therefore, second vase consist of 6 begonias and 6 daffodils
