Answer:
175<=12.5x+40
Step-by-step explanation:
She starts with 40 points already so you add in those 40 then since she gets 12.5 points per visit that is your x, so you set that as greater than or equal to 175
The answer is 63 cm bc 30 60 90 triangles have a rule where the short leg is x longer is x√3 and the hypotenuse is x2
you can see this if you imagine the triangle as equilateral then cutting it in half
False, that is the Pythagorean theorem.
1/(x+5) because the (x-2) is canceled from both the numerator and denominator of the equation.
Answer:
E
Step-by-step explanation:
.03(50) + 0x = (50-x).05 How much 3% salt much be added to zero percent salt to create a mixture that is 5 percent salt.
3(50) = (50 - x)5 I multiplied through by 100 to clear the decimals
150 = 250 - 5x Distribute the 5
-100 = -5x Subtract 100 from both sides of the equation
20 = x divide both sides by -5
