The following question has two parts. First, answer part A. Then, answer part B.

Paha777 [63]

The answer to Part A is 13.25.
And the answer to Part B is hen you round to the nearest 10th the steps are nearly always the same:Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

Answer:

The answer is 18,900 Joules.

Step-by-step explanation:

If you work out the equation

Half of 350 is 175

12 squared is 144

6 squared is 36

Subtract 36 from 144 and get 108

108 multiplied by 175 is 18,900

Solve the proportion

Cross Multiply~

11x10=110

2 (times) x= 2x

2x=110

Divide 2 on both sides

2x/2=x

110/2=55

x=55

Solving systems elimination: I don’t understand how to solve at all. Please help if you can.

The solution to given system of equations y = 3x - 9 and y = -2x + 16 are (x, y) = (5, 6)

The solution to given system of equations y = 5x + 22 and -6x - 4y = -10 are (x, y) = (-3, 7)

Solution:

Given that, we have to solve each system by substitution method

Given system of equations are:

y = 3x - 9 ----------- eqn 1

y = -2x + 16 -------- eqn 2

Substitution method is done by substituting eqn 2 in eqn 1

Substitute the value of "y" from eqn 2 into eqn 1

-2x + 16 = 3x - 9

Move the variables to one side and constants to other side

-2x - 3x = -9 - 16

Combine the like terms

-5x = -25

Cancel the negative sign on both sides of equation

5x = 25

$x = \frac{25}{5} = 5$

Substitute x = 5 in eqn 1

y = 3(5) - 9

y = 15 - 9

Thus solution to given system of equations are (x, y) = (5, 6)

Given another system of equations are:

y = 5x + 22 ----- eqn 1

-6x - 4y = -10 ------ eqn 2

Substitute eqn 1 in eqn 2

-6x - 4(5x + 22) = -10

-6x - 20x - 88 = -10

Move the variables to one side and constants to other side

-26x = -10 + 88

-26x = 78

Substitute x = -3 in eqn 1

y = 5( - 3) + 22

y = -15 + 22

Thus solution to given system of equations are (x, y) = (-3, 7)

Write an equation for the line shown on the graph.

musickatia [10]

Answer:

$y = \frac{2}{3}x + 1$

Step-by-step explanation:

Starting from the y-intercept of $[0, 1]$ , we do $\frac{rise}{run}$ by either moving two blocks south over three blocks west or two blocks north over three blocks east [west and south are negatives].

* If you take a very good look at this answer, you will see that you do not have this as an answer choice.
