Plz ! need this asap! thx! problem: solve the following problems. it may be to set up an equation. there are two numbers, one is 7 more than twice the other. the sum of the numbers is 43. make the equation to find the smaller number. find the two numbers. if the smaller number is x, the equation will be the numbers in ascending order are and

the answer is x+2x+7= 43 and the number are 12 and

Step-by-step explanation: So the equation is basically explanitory and I got my answer my solving this equation

for elimination subtract as is
y=-x+4
y=-2x-4

0 = 1 x + 8
so
x = -8
then get y = 8+4 = 12)

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

the solution is 12x-6y
