Answer:

B. 1010

Step-by-step explanation:

<u>Simplify:</u>

  • (ab0+ab0ab) ÷ (ab) - 1

<u>Note that:</u>

  • ab = 10a +b
  • ab0 = 10* (10a + b) = 10ab
  • ab0ab = 1000ab + ab = 1001 ab

<u>Therefore:</u>

  • (ab0+ab0ab) ÷ (ab) - 1 =
  • (10ab + 1001ab) ÷ (ab) - 1 =
  • (1011ab) ÷ (ab) - 1 =
  • 1011 - 1=
  • 1010

<u>Correct choice is</u> B.1010

the following equation represents the total distance (d) that the Benson family has traveled from their home, after traveling 10
Pani-rosa [81]

Answer:

The distance the Bensons had traveled from their home 3\frac{1}{2} hours after picking up their grand parents  292.5 miles

Step-by-step explanation:

The given equation for the distance the Benson family traveled from their home can be presented as follows;

d = 55·t + 100

Where;

d = The total distance that the Benson family has traveled from their home after traveling 100 miles to pick up their grandparents

t = The time duration the Benson family have been traveled from their grandparents home on the way to their vacation

To find how far from their home the Bensons will be after 3 1/2 hours of driving with their grand parents, we substitute t with 3 1/2 hours or 3.5 hours as follows;

d = 55·t + 100

When t = 3\frac{1}{2} hours, we get;

d = 55 \times 3\frac{1}{2} + 100 = 292.5  \ miles

Therefore, the distance the Bensons had traveled from their home 3\frac{1}{2} hours after picking up their grand parents = 292.5 miles.

2x+3y=12 find four solutions​
Nana76 [90]

Answer:

y = 0 and x = 6

y = 2 and x = 3

y = 4 and x = 0

y = 6 and x = -3

Step-by-step explanation:

2x+3y=12 is the equation of a straight line.

There are infinite number of solutions, but here you're probably looking for solutions where x and y are whole numbers. Trial and error will find you some, although if you examine the equation closely you see that if x is a multiple of 3 and y is a multiple of 2, then they produce terms that are the LCM (least common multiple) of 2 and 3, namely 6. That's the logic in the whole number solutions.

The graph shows the proportions of blue paint and yellow paint that Briana mixes to make green paint. What is the slope of the l
kotegsom [21]

Answer:

Slope = ⅚

Step-by-step explanation:

Using the coordinates of two points in the graph, say (0, 0) and (6, 5).

\frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 0}{6 - 0} = \frac{5}{6}

The slope of the graph is ⅚.

The slope represents the ratio of proportion of yellow paint to blue paint that must be mixed together to produce green paint.

This means, to make green paint, for every 5 parts of yellow paint, 6 parts of blue paint is required to be added as a mixture.
