At a candy store you could get 3 giant lollipops for $4.89. how much would it cost to buy 6 lollipops?

9.78

Step-by-step explanation:

4.89/3 = 1.63

this is the unit rate or what she paid for each lolipop

so 6x1.63=9.78

The cost of 6 giant lollipop is $9.78

Step-by-step explanation:

Given

Number of giant lollipops = 3

Cost of these lollipops = $4.89

Required: Cost of 6 lollipops

To calculate the cost of buying 6 lollipops of the same size; Follow the highlighted steps below

Step 1: Calculate the cost of a giant lollipop

Given that 3 lollipops costs $4.89

The cost of one lollipop can be gotten by simply dividing the cost of 3 lollipops by 3.

Let x represent the cost of 1 lollipop,

Mathematically, we have

Divide both sides by 3

Hence, the cost of 1 giant lollipop is $1.63

Step 2: Calculate the cost of 6 giant lollipops

If the cost of 1 giant lollipop is $1.63

The cost of 6 would be 6 * the cost of 1 giant lollipop

Let y represent the cost of 1 lollipop,

Mathematically, we have

Hence, the cost of 6 giant lollipop is $9.78

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
