Step-by-step explanation:

DBC = TBC + DBT

DBT = DBC - TBC

DBT = 25X +7 -( 12X + 5 )

DBT = 25X + 7 - 12X -5

DBT = 13 X + 2

TBC = 12x + 5

DBC = 25x + 7

Step 1: Add all the values

95+98+32= 225

Step 2: Divide

\frac{225}{3} =75

Step 3: Check your work

75*3 =225

Answer as quickly as you possibly can
klemol [59]

Answer:

m = 3/2

Step-by-step explanation:

You want to find the slope, or the change in y coordinates over change in x-coordinates.

The first given point is E(-2, -4)

The second point is F(2, 2)

Coordinates are given in (x, y), so following the equation and computing the  x and y coordinates of E - F for both the numerator and denominator:

\frac{y_2 - y_1}{x_2-x_1}  =  \frac{-4 -2}{-2 -2} = \frac{-6}{-4} = \frac{3}{2}

You could also have went the other way and calculated F - E for the numerator and denominator and get the same answer.

Finally, to check you can also look at the graph through the rise over run (rise/run) method and see that from E, you go up 3 (rise) and to the right 2 (run) to get to the next point on the line.

100 points.<br> Find the surface area of the triangular prism. The unit is cm^2
nikklg [1K]
First we find the area of the two triangles on each side (keep in mind that they are equal/congruent to each other):

(24*10)/2 = 120 cm^2

Then you find the areas of the three rectangles that are left:

24*19 = 456 cm^2
26*19 = 494 cm^2
10*19 = 190 cm^2

Finally, to find the surface area of the prism:

120+120+456+494+190 = 1,380 cm^2

Deon bought a desktop computer and a laptop computer. Before finance charges, the laptop cost $250 less than the desktop. He pai
zysi [14]

Answer:

300

Step-by-step explanation:

Let x = cost of desktop computer; then x - 250 = cost of laptop computer

converting % to decimals, 9% = 0.09 and 6% = 0.06

Then, 0.09x + (x - 250)0.06 = $300

0.09x + 0.06x - 15 = $300

0.15x = $315

x = $2100

then x - 250 = $1850

Proof: $2100•0.09 + 1850•0.06 = $189 + $111 = $300
