Let the number of child tickets sold be x, and number of adult tickets be y, then
5.70x + 9.50y = 543.40 . . . (1)
y = 2x . . . (2)
Putting (2) into (1), gives
5.7x + 9.5(2x) = 543.4
5.7x + 19x = 543.4
24.7x = 543.4
x = 543.4/24.7 = 22
Therefore, 22 child tickets were sold.
Answer:
<u>x=10</u>
Let's solve your equation step-by-step:
4x+40=80
<em>Step 1: Subtract 40 from both sides</em>
4x+40−40=80−40
4x=40
<em>Step 2: Divide both sides by 4</em>
4x/4=40/4
Answer:
<u>x=10</u>
Answer:
x = ∛(-21/6)
Step-by-step explanation:
Multiply both sides by 20 to remove the fractional coefficients:
5x^3 = -108
Divide both sides by 5:
x^3 = -21/6
Then x = ∛(-21/6)
Answer: 3x^4+7x^3+7x^2+11x+4
Step-by-step explanation:
(x^2+3x+4)(3x^2-2x+1)
3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4
Collect like terms
3x^4-2x^3+9x^3+x^2-6x^2+12x^2+3x+8x+4
3x^4+7x^3+7x^2+11x+4
