<span> Arithmetic sequence.
a</span>₁ = 13.1; a₂ = 3.1
d = a₂ - a₁ = 3.1 - 13.1 = -10
a₄₃ = a₁ + d(n-1) = 13.1 - 10(43-1) = 13.1 - 10 * 42 = 13.1 - 420 = -406.9
Answer: -406.9
Hi,
So if I read correctly, there are 788 students each getting one of four colors of t-shirts (and there are an equal number of shirts per color). To do this, all you need to do is divide the number of students (788) by the number of colors (4) to see how many students get each color of t-shirt.
788 ÷ 4 = 197
Red is one of the four colors, and 197 is exactly one fourth of the students, so one-fourth of the students (197) get red.
Answer:
x=4
Step-by-step explanation:
distributive property goes first.
you get 6x-9=15
add 9 on both sides so 9 cancells out on the left side.
you get 6x=24
divide by 6 and you get x=4
Answer:
His total is $269
Step-by-step explanation:
8x19 = 152
6x19.50 = 117
152+117 = 269
You need to divide the numerator by the denominator so it should be 8 divided by 9 to turn it into a percent multiply the decimal you get by 100. Hope this helps!
