Answer:
2=y 5=x
Step-by-step explanation:
its the answer of your question
I think it’s 348.75 or as a mixed number 348 3/4
X= 1st integer
x+2= 2nd integer
x+4= 3rd integer
Add the integers together
x + (x + 2) + (x + 4)= 279
combine like terms
3x + 6= 279
subtract 6 from both sides
3x= 273
divide both sides by 3
x= 91 first integer
Substitute x=91 to find 2nd & 3rd integers
2nd Integer
=x+2
=91+2
=93
3rd Integer
=x+4
=91+4
=95
ANSWER: The three test scores are 91, 93 and 95.
Hope this helps! :)
Answer:
3
Step-by-step explanation:
4(a) The first 3 terms are:
₅C₀ (3)⁵ (bx)⁰ = 1 × 3⁵ × 1 = 243
₅C₁ (3)⁴ (bx)¹ = 5 × 3⁴ × bx = 405b x
₅C₂ (3)³ (bx)² = 10 × 3³ × (bx)² = 270b² x²
4(b) The coefficient of x² (the third term) is twice the coefficient of x (the second term).
270b² = 2 (405 b)
270b² = 810b
270b = 810
b = 3
