Step-by-step explanation:

  • 6x-3=11
  • 6x=11+3
  • 6x=14
  • x=14/3
  • x=2.33

  • 15=x/3+2
  • 15-2=x/3
  • 13=x/3
  • x=13×3
  • x=39

  • -4(x-1)=7(x+4)
  • -4x+1=7x+28
  • -4x-7x=28-1
  • -11x=27
  • x=27/-11
  • x=2.45

  • 3(2x+1)=6x
  • 6x+1=6x
  • 6x-6x=1
  • <em>No </em><em>solution</em>

Answer:

Step-by-step explanation:

1)

6x-3=11

6x=11+3

6x=14

x=2.33

2)

15=x/3+2

-2+15=x/3

13=x/3

x=31

3)

-4(x-1)=7(x+4)

-4x+4=7x+28

-4x-7x=-4+28

3x=24

x=8

4)

3(2x+11)=6x

6x+33=6x

33=-6x+6x

no solution

In a dessert, the ratio of the number of ounces of dark chocolate used to the number of ounces of white chocolate used is 8 : 5
leva [86]

Answer:

1.6 ounces

Step-by-step explanation:

Divide the ratio by 5 to get the number of ounces of dark chocolate used for 1 ounce of white chocolate, since 5/5 = 1

8/5 = 1.6

5/5 = 1

The new ratio is 1.6 : 1

This means that 1.6 ounces of dark chocolate are used for every 1 ounce of white chocolate

IRINA_888 [86]

Answer:

1. 600 cm^3

2. 24 cm^3

3. 540 cm^3

4. 1476 cm^3

Step-by-step explanation:

1. rectangular prism volume equation is: V = lwh, where l = length, w = width, h = height. Substitute known values into this equation: V = 5 x 8 x 15 and we get V = 600 cubic cm.

2. V = (1/2)bhl, where the base and height are dimensions of the triangle. V = (1/2)6 x 2 x 4 and we get V = 24 cubic cm

3. V = Bh, where B is the base area and h is the perpendicular height. V = 45(12). So, V = 540 cm^3

4. Same thing with this one: V = Bh. Substitute known values into this equation: V = 82(18), which means V = 1476 cm^3
