solve the equation
0.2(d-6)=0.3d+5-3+0.1d for d

Answers

Answer 1

Answer:

d= -16

Step-by-step explanation:

To answer this question you'll have to first simplify the equation to

0.2d+-1.2=0.3d+5-3+0.1d

then combining like terms you get

0.2d-1.2=(0.3d+0.1d)+(5+-3)

0.2d-1.2=0.4d+2

then subtract 0.4d from both sides leaving you with

-0.2d-1.2=2

then add 1.2 to both sides

-0.2d=3.2

after you divide both sides by -0.2

leaving you with the answer

D= -16

Answer 2

Answer:

D = -16

Answer:

  28 square units

Step-by-step explanation:

The figure can be decomposed several ways. Maybe easiest to see is as a 8×4 rectangle with a 2×4 right triangle cut from the corner.

The area of the rectangle is ...

  A = LW = (8)(4) = 32

The area of the missing triangle is ...

  A = 1/2bh = 1/2(2)(4) = 4

Then the area of the shaded figure is ...

  32 - 4 = 28 . . . square units

_____

Alternate solution

If you divide the figure with a horizontal line across the middle, it becomes a 4×4 square and a trapezoid with bases 2 and 4 and height 4. The shaded area is the sum of these areas.

The area of a trapezoid is ...

  A = 1/2(b1 +b2)h

  A = (1/2)(2 +4)(4) = 12

The area of the square is ...

  A = s² = 4² = 16

Then the total area is ...

  12 +16 = 28 . . . square units

Without doing any calculations, compare expression A to expression B.

Write a function rule for “The output is 6 more than five times the input.” Use x for the independent variable and y for the dependent variable. y=

Answers

Answer:

y=5x+6

Step-by-step explanation:

+6 is six more than.

5x is five times the input.

For example, let's say x=3. you gotta multiply first so you can get the five times out of the way. 3×5=15. Now we got to add six because "6 more than" means to add six. so, 15+6=21. I plugged in 21 for y to check and I got x=3, so this works.

buys the dress when it is on sale for 10%

off its original price.
How much more money did Julie spend than Mindy on the dress?

$ [blank]

Enter your answer as a number. If it is a decimal, round it to the nearest whole number, like this: 42

Answers

Answer:

Julie spent $10 more on the dress.

Step-by-step explanation:

Say the dress's original price is 100.

10% of 100 is 10. so Julie would've paid $90 for the dress

If Mindy buys the same dress when it is 20% off she would've paid $80 for the dress.
