7 0

Answer:

0.1 is the answer of that equation but 0.1 can also be written as 0.100 or 0.10000 or and amount of zero just when you have zeros in the decimal places you usally dont count them so 0.100 is the same as 0.1 the same would also call for somthing like 0.40000 it can be written as 0.4 instead.

Write the linear equation in slope intercept form 2x+By=16
allochka39001 [22]

Answer:

Part 1) y=-\frac{2x}{B}x+\frac{16}{B}

Part 2) y=-\frac{1}{4}x+2

Step-by-step explanation:

Part 1)

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

we have

2x+By=16

Isolate the variable y

subtract 2x both sides

By=-2x+16

Divide by B both sides

y=-\frac{2x}{B}x+\frac{16}{B}

Part 2)

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

we have

2x+8y=16

Isolate the variable y

subtract 2x both sides

8y=-2x+16

Divide by 8 both sides

y=-\frac{2x}{8}x+\frac{16}{8}

Simplify

y=-\frac{1}{4}x+2

Use what you know about the properties to rewite each number sentence. Use mental math to find the sum. 0.6 + (0.4 + 0.9) = n an
dusya [7]

First Equation:

0.6 +(0.4+0.9) =n

Step 1: do parentheses first:  

0.4+0.9 = 1.3

Step 2: Add 0.6 + 1.3

0.6 + 1.3 = 1.9

n= 1.9

Second Equation:

(1.57 + 0.75) + 0.25 + n

Step 1: do parentheses first:

1.57 + 0.75 = 2.50

Step 2: Add 2.50 + 0.25 = 2.75

Step 3: Add 2.75 and n = 2.75+n

Final Answer:

1.9 +2.75+n = 4.65 +n

Hope this helps!!
