Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtract Property of Equality

Step-by-step explanation:

Step 1: Define Systems

x + y - 6 = 0

x - y = 0

Step 2: Rewrite Systems

x + y - 6 = 0

Add 6 on both sides: x + y = 6

Step 3: Redefine Systems

x + y = 6

x - y = 0

Step 4: Solve for x

Elimination

Combine 2 equations: 2x = 6
Divide 2 on both sides: x = 3

Step 5: Solve for y

Define equation: x - y = 0
Substitute in x: 3 - y = 0
Subtract 3 on both sides: -y = -3
Divide -1 on both sides: y = 3

4(3/(8+1) = 4(3/9) = 12/9 = 4/3

4((3/8)+1) = 4(11/8) = 44/8 = 11/2

just depends on which way the equation is written

Tanzania [10]

Answer:

Step-by-step explanation:

There are 48 flavors and toppings. Since 16 are flavors, 32 are toppings. Dividing the 32 topping equally between 8 children is 4 toppings per child.

32 ÷ 8 = 4

Gerardo works at an ice cream shop each flavor of ice cream is stored in a right cylindrical tub that measures approximately 9 i

Leokris [45]

Answer:

Volume left = 404.32 cubic inches

Step-by-step explanation:

volume of a cylinder = $\pi$ $r^{2}$ h

volume of ice cream in the cylindrical tub = $\frac{22}{7}$ x $5^{2}$ x 9

= $\frac{22}{7}$ x 25 x 9

= 707.1429

Volume of ice cream in the cylindrical tub is 707.14 cubic inches.

The ice cream scoop has a spherical volume, so that;

volume of a sphere = $\frac{4}{3}$ $\pi$ $r^{3}$

r = $\frac{2.5}{2}$

= $\frac{5}{4}$ inches

volume of the scoop = $\frac{4}{3}$ x $\frac{22}{7}$ x $(\frac{5}{4} )^{3}$

= $\frac{4}{3}$ x $\frac{22}{7}$ x $\frac{125}{64}$

= 8.1845

volume of the scoop is 8.19 cubic inches.

If he scoops 37 scoops,

volume of the 37 scoops = 37 x 8.1845

= 302.8265

volume of 37 scoops is 302.83 cubic inches.

Volume of ice cream left in the tub = 707.1429 - 302.8265

= 404.3164

Volume of ice cream left in the tub is 404.32 cubic inches.
