Emma has $x in her bank account. Jonah has $40 more than twice as much as Emma in his bank account. Together they have $760. Write and solve an equation to determine how much money Emma
has in her bank account.

$240

Step-by-step explanation:

We can set this up by making an equation: x + 2x + 40 = 760.

Now we can solve.

x + 2x + 40 = 760 (combine like terms (x))

3x + 40 - 40 = 760 - 40 (subtract 40 from both sides)

3x / 3 = 720 / 3 (divide by 3 to isolate x)

x = 240

Because Emma has $x, she has $240 in her bank account.

You can check this by substituting this value for x in our original equation.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
