I'd say 100 even, don't know if this is a real question or not.
Answer/Step-by-step explanation:
A term in an algebraic expression is a number standing on its own (constant), a letter (variable), or a number multiplying a variable (coefficient * variable).
Given the expression, 9a + 4b - 18, there are three terms in the expression, namely: 9a, 4b, and -18.
The student made an error in identifying the terms properly by excluding the variables, a and b, in the first term (9a) and in the second term (4b), respectively.
The correct terms are: 9a, 4b, and -18.
Answer:
Shown Below
Step-by-step explanation:
Alright so first off we are going to use the little 67 on that corner. We know that it's a supplementary angle, and supplementary angles add up to 180.
180 - 67 = 113.
Inside angles of a triangle all add up to 180. Using that we can create the equation:
(x + 27) + x + 113 = 180
simplify.
2x + 140 = 180
subtract 140 on both sides.
2x = 40
divide both sides by 2
x = 20
substitute x into the asked equation.
(20 + 27) = 47
47 is your answer.
Answer:
6y+15
Step-by-step explanation:
Product is multiplication so write 6y. Increased means to add so write +15. Now combine into 6y+15.
5≤x≤9 it can also be reversed as 9≥x≥5 which is the same thing
