1 answer:

4 0

If the given quantities are 10 quarters 17 dimes 40 nickels 15 pennies then the total money would be 6.35 dollars.

<h3>What is the fundamental principle of multiplication?</h3>

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Quarters are worth .25 of a dollar

10 x .25 = 2.5

Dimes are worth .10 of a dollar

17 x .10 = 1.7

Nickels are worth .05 of a dollar

40 x .05 = 2

Pennies are worth .01 of a dollar

15 x .01 = 0.15

Add this together

2.5 + 1.7 + 2 + 0.15

= 6.35

Answer: the cost of a milkshake is $2.59

Step-by-step explanation:

Let x represent the cost of a banana split.

Let y represent the cost of a milkshake.

At the ice cream shop, one banana split and five milkshakes cost $16.24. This is expressed as

x + 5y = 16.24- - - - - - - - - - - - -1

If three banana splits and two milkshakes cost $15.05. This is expressed as

3x + 2y = 15.05- - - - - - - - - - - - -2

Multiplying equation 1 by 3 and equation 2 by 1, it becomes

3x + 15y = 48.72

3x + 2y = 15.05

Subtracting, it becomes

13y = 33.67

y = 33.67/13

y = 2.59

Substituting y = 2.59 into equation 1, it becomes

x + 5 × 2.59 = 16.24

x + 12.95 = 16.24

x = 16.24 - 12.95

x = 3.29

Elanso [62]

Answer:

The measure of angle BCD is $68.5\°$

Step-by-step explanation:

step 1

Find the value of x

we know that

$m$ -----> form a straight line

substitute the values

$(3x+4)\°+(6x-8)\°+(7x-20)\°=180\°$

$(16x-24)\°=180\°$

$16x=180\°+24\°$

$16x=204\°$

$x=12.75\°$

step 2

Find the measure of angle BCD

Can someone tell me the answer and show me how to find it?

kiruha [24]

Answer:

The value of x is 20°

Step-by-step explanation:

Given that angle in a straight line is 180°. Then you can find the value of x:

55° + (6x+5)° = 180°

55° + 6x + 5° = 180

6x + 60° = 180°

6x = 180 - 60

6x = 120°

x = 20°
