Isolate x, so add 5 to each side

-2.49 =  -5 + x

+5.00    +5

3.49 = x

Answer:

x= 251/100

Marrisa added 1.56 and 13.47. She got 29.07. What mistake could Marrisa have made? She forgot to move the decimal point to the left after she added. She lined up the front numbers instead of the decimal places. She lined up the last numbers instead of the decimal places. She didn’t carry correctly between place values.

Answers

without an explanation your answer is (B) She lined up the front numbers instead of the decimal places.

if you need an explanation here:

________________________________________

For a problem with a decimal in the numbers, you ALWAYS have to line them up or your answer will be incorrect.

She should have put: 13.47

                                 +  1.56

                                    15.03

therefore, 15.03 would have been her correct answer. :-)

Henry needs 2 pints of red paint and 3 pints of yellow paint to get a specific shade of orange. If he uses 9 pints of yellow paint and wants the same orange color, how many pints of paint will he need altogether? Explain how you know. 2

Answers

Answer:

Henry needs 15 pints of paint altogether

Step-by-step explanation:

If Henry uses 2 pints of red paint and 3 pints of yellow paint to get a specific color, and he now uses a total of 9 pints of yellow, then

3 x 3 = 9 (yellow)

We know that what you do on one side, you do on the other.

2 x 3 = 6 (red)

You add

9 + 6 = 15. (Red and yellow paint)

Which will lead you to the conclusion of 15 pints.

Answer:

Henry will need 15 pints altogether.

Step-by-step explanation:

Add: 6 + 9 = 15 pints

Answer:

  B

Step-by-step explanation:

AB and CD are the same length, so the construction will be one that shows addition of same-length segments. In choices A and C, XY > YZ. In choice D, XY < YZ. Only choice B shows addition of same-length segments.

As a check, you can compare the length of AB or CD to XY or YZ. You will find they are approximately the same, as they should be.

slope 5/6, passes through (12,4)

Answers

Answer:

y= 5/6x -6

Step-by-step explanation:

[tex]m =\frac{5}{6} \\(12,4)=(x_1,y_1)\\\\[/tex]

Substitute values into point slope form

[tex]y-y_1 =m(x-x_1)\\\\y - 4 = \frac{5}{6} (x-12)\\\\y-4 = \frac{5}{6} x -10\\\\y=\frac{5}{6} x -10+4\\\\y = \frac{5}{6} x -6[/tex]

The equation of the line that has a slope of 5/6 and passes through (12, 4) will be y = 5/6) x - 6.

What is a linear equation?

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The slope of the line is 5/6. Then the equation of the line will be

y = (5/6)x + c

The equation of the line is passing through (12, 4), then the value of c will be

4 = (5/6) 12 + c

4 = 10 + c

c = -6

Then the equation of the line will be y = (5/6)x - 6.
