It's B.) The student’s answer is not reasonable. Estimation: 170 + 90 = 260

The answer is B because if you round to the nearest 10, B would be the answer. C is not correct because 93 rounded to the nearest 5 (like 175) is not 100. A is not correct because the estimation is not reasonable. D is also not correct because you would need to add the numbers, not subtract.

Answer:

Water (one oxygen atom bonded to two hydrogen atoms)

Step-by-step explanation:

The chemical formula for water is H²O. The H is the chemical symbol for Hydrogen and O is the chemical symbol for Oxygen. The 2 is a subscript which represents how many atoms of a certain element are in a molecule. In this case, the subscript ² comes after H, indicating that there are two Hydrogen atoms inside water. There is no subscript after O, meaning there is only one Oxygen atom. Therefore, there are two Hydrogen atoms and one Oxygen atom that bond to form water. Hope this helps :))

The tables show linear relationships between x and y. Write an equation in slope-intercept form for each relationship.
Alenkinab [10]
The first thing you need to do is calculate the slope. pick 2 of the ordered pairs.

i'll use (1, 4) and (0, 6)

m = (6 - 4)/(0 - 1)
m = (2)/(-1)
m = -2

so the slope is -2. slope intercept form is written as y = mx + b and you have one part of that equation

y = -2x + b

to find b, use one of the selected points. i'll use (0, 6).

(6) = -2(0) + b
6 = b
b = 6

therefore:

y = -2x + 6

Solve the system by elimination state whether the system has one solution infinite solutions or no solution x+3y=-5 4x-y=6
STatiana [176]

Answer:

one solution, i.e x = 1 and y = -2

Step-by-step explanation:

Given two equations :

x+3y = -5   -------(1)

4x - y =6   ---------(2)

Using elimination method,

Multiply equation (2) by 3 and add it to equation (1)

We get,

x + 3y + {(4x - y)×3} = -5 +(6×3)

x + 12x + 3y - 3y = -5 + 18

13x = 13

x = 13/13  = 1

And corresponding y will be:

x + 3y = -5   , Plug x =1  to get y

1 + 3y = -5

3y = -5 - 1

y = -6/3 = -2

Hence we got only one solution, i.e x =1 and y = -2
