D. Indirectly from the herbicore
Answer:y=5
Step-by-step explanation:
To find out what y is you have to do the inverse to 'undo' the equation.
So instead of multiplying y by 8 you have to divide 40 by 8.
40÷8=5
So y=5
You can check your answer by putting 5 where y is.
40=8×5
Hope this helps :)
Answer is 2(x,y) —> (3x, 3y)
The population of the state of California was about 37,250,000 people in 2013. Which number best approximates the population as a single digit times a power of 10?
A. 3 × 10⁻⁶
B. 4 × 10⁻⁷
C. 3 × 10⁶
D. 4 × 10⁷
Answer:
Option D = 4 × 10⁷
Step-by-step explanation:
We are given the population of people = 37,250,000 people
We round to a power of 10
and that would give us 3.7 × 10⁷
We are told in the question to approximate the population as a single digit,
3.7 × 10⁷ s a single digit = rounding up to the nearest whole number
= 4 × 10⁷.
Therefore, the number that best approximates the population as a single digit times a power of 10 is
= 4 × 10⁷
Answer:
C. Use properties of equality to get the variable on one side of the equation and constant terms on the other.
Step-by-step explanation:
In solving an equation, It is true that properties of equality should be used by putting the variable on one side and the constant on the other side.
Now let use an example to drive this;
Given:
2x - 9 = x + 8
This is an equation, and what we have on both sides should be equal.
Collect like terms;
2x - x = 8 + 9
x = 17
So the solution is 17.
This is the best way to solve an equation.
