So Chris would have 1x, David would have 2x, and George would have 4x, so add them together and get 7x, so you divide by 7 and that's 3=x so Chris would have 3, David would have 6, and George would have 12
Answer:
it is b
Step-by-step explanation:
Answer:
Standard Description: Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. (Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.)
Step-by-step explanation:
the explanation and answer is there in above
Answer:
A rea of a Circle = π × r²
Step-by-step explanation:
The area of a circle formula is A = π × r² where r is the radius.
Remember that the radius might not be given but the radius is half of the diameter.
For π use the calculator value or use 3.14.
<span>4x(x) + 3(2x) and 4x2 + 6x => 4x^2 + 6x and 4x^2 + 6x
5(3x) - 4(3x) and 3x => 15x-12x=3x and 3x
4(3a) - 2(4a) and 4a2 => 12a-8a=4a and 4a^2
3(3a) + a(3a) and 3a2 + 9a => 9a+3a^2 and 9a + 3a^2
Can you spot the one which is different?
