Answer 1
Answer:

Answer:

4 times 10 to the negative seventh power

Step-by-step explanation:

We can see that the decimal has 6 zeros before it, and then it’s 4.

since there are 7 digits after the decimal point, we put 10 to the negative seventh power.

that gives us 0.0000001

to get 0.0000004, we need to multiply ten to the negative seventh power (0.0000001) by 4

Answer 2
Answer:

The answer is a. which is 4 x 10‐⁷

2x+y=4
Y=2/3x-4

Answers

so you subsitute y=2/3x-4 for y in 2x+y=4 so
2x+(2/3x-4)=4
2x+2/3x-4=4
add like terms
2 and 2/3x-4=4
add 4 to both sidees
2 and 2/3x=8
   2 and 2/3=6/3+2/3=8/3
8/3x=8
multiply both sides by 3/8 (makes 8/3=24/24=1/1=1)
x=(3*8)/8
simplify
x=3
subtitute x=3 into y=2/3x-4
y=2/3(3)-4
y=(6/3)-4
y=2-4
y=-2

B. One of the equations may easily be solved for a variable.
C. An exact solution is needed.
D. Both of the equations are solved for one variable.

Answers

If you want to substitute, you need to solve an equation for a variable.  I ONLY use this method if I can easily solve one equation for a variable, and then it is a maybe.  For this case use B

Solve this equation for A: A ÷ 2 = 4

Answers

The value of A will be equal to A=8 for the given expression.

What is expression?

Mathematical expressions are combinations of numbers and variables ordered with operations.

We have the expression.

(A)/(2)=4

A=4* 2

A=8

Hence the value of A will be equal to A=8 for the given expression.

A divided by 2 equals 4.

1) do inverse operation which is multiplication
2) do 2 times 4
3) that equals 8
4) now we plug it in a= 8
5) we check our work....
     8/2 = 4
Yay! it fits now we know our answer a=8 is correct!

Which is bigger: 0.3 or 1/3

Answers

The bigger number is 1/3. That is, 1/3 is bigger than 0.3

To determine which is bigger between 0.3 and 1/3.

First, we will express 0.3 as a fraction

0.3 = 3/10 as a fraction

Now we are to determine which is bigger between (3)/(10) \ and \ (1)/(3)

By LCM method,

(3)/(10) \ and \ (1)/(3) = (9)/(30) \ and \ (10)/(30) respectively

Since, the corresponding numerator(10)of (1)/(3) is greater than the corresponding numerator(9) of (3)/(10),

(1)/(3) is bigger that (3)/(10)

Hence, 1/3 is bigger than 0.3

First, turn the fraction into a decimal to get a better look at the problem. To do that, divide the numerator (top half) by the denominator (bottom half). 1 divided by 3 = 0.33
0.33 is larger than 0.3. If it helps, add a 0 to 0.3 to get 0.30 and you'll see that 33 is in fact a larger number than 30. (Adding the zero does NOT change the number, it holds no place value it's just there for looks.)
