What are two consecutive integers such that two times the first is 43 more than the second

Virty [35]

You can think of two consecutive integers as n and n+1, and hence create an equation:
$2n = (n + 1) + 43 = n + 44$
Rearranging the equation by subtracting n from both sides
$n = 44$
Hence, your two consecutive integers are n and n+1 i.e. 44 and 45
You can check this: 44•2 = 88 = 45+43

Half of a number increased by 4 is 30.

Hitman42 [59]

Answer:

$\frac{1}{2}x+4=30$

Step-by-step explanation:

First, write the equation out in the algebraic form. Half of a number is equivalent to a number times 1/2. Additionally, increasing a number by 4 is just adding 4. So the equation is $\frac{1}{2}x+4=30$ .

Then, use algebra to solve.

1) Subtract 4 from both sides

1/2x=26

2) Multiply both sides by 2, because that is the same as dividing by a fraction

x=52
