Question and answer

Write whether each expression is a monomial or a binomial. a. 3y b. (–9) + h c. wr + 5wr d. –7agh e. 2 f. k + 12

a. 3y - monomial b. (-9) + h = -9 + h = h - 9 - binomial c. wr + 5wr = 1wr + 5wr = (1 + 5)wr = 6wr - monomial d. -7agh - monomial e. 2 - monomial f. k + 12 - binomial

This answer has been confirmed as correct and helpful.

The sum of three certain consecutive numbers is 240. Find the three numbers. [Hint: Let x stand for the smallest number. Since the numbers are consecutive, add 1 to get the second number (x + 1) and add 2 to get the third number (x + 2).]

Weegy: The sum of three certain consecutive numbers is 240. x + x +2 + x + 4 = 240, 3x + 6 = 240, 3x = 240 -6 ; 3x = 234 , x = 234/3 = 78, x = 78 , x + 2 = 78 + 2 = 80 , x + 4 = 78 + 4 = 82. User: Amy, Doug, and Ginger took a math test. Amy scored 12 points higher than Doug, and Ginger scored twice as many points as Doug. The total points the three friends received was 208. How many points did Doug score on the test? (More)

Amy(A): D + 12
Doug(D):D
Ginger(G):2D
SumOfAll(S)=208 : Total points / sum of all three friends

(D+12)+D+2D=208
D+12+3D=208 - transpose 12 to the right side
4D=208-12
4D = 196 - divide both sides by 4
D=49
Therefore, Doug scored 49
