1.3b+7.8-3.2b Combine like terms pls

Mathematics
2 answers:
irakobra [83]4 years ago

Answer:

−1.9b + 7.8

Step-by-step explanation:

This is the answer because:

1) Like terms are numbers or variables that are the same/ "alike"

2) 1.3b and -3.2b are like terms, so we have to combine them

3) 1.3b - 3.2b = 1.9b

4) Finally, 7.8 is the number that is left. This is not a like term in this expression because it does not have the same variable.

Therefore, the answer is  -1.9b + 7.8

Hope this helps!

a windowpane is 5.7 Inches by 7.1 inches. what is the distance between opposite corners of the windowpane? if necessary, round t
nikitadnepr [17]

Answer:

the distance is 9.1 inches (please give brainliest)

Step-by-step explanation:

we must use the pythagorean theorem:

5.7^2 + 7.1^2 = c^2

(c being the distance being the two corners)

c^2 = 82.9

c = sqrt(82.9) ≈ 9.1

What is the inverse of the function f(x) = 2x - 10?
love history [14]
F(x)=2x-10

y=2x-10

x=2y-10

x+10=2y-10+10 (add both sides by 10)

2y=x+10

2y/2=x+10/2 (divide both sides by 2)

y=1/2x+5

Final Answer: f^-1(x)=1/2x+5
