Answer:

Luis traveled 11.82 km in total.

Step-by-step explanation:

<em>The statement should say</em>: To visit his grandmother, Luis takes a train 6.37 kilometers and a car 5.45 kilometers. How many kilometers is Luis's journey in total?        

Hence, to find the total distance traveled by Luis we must add the distances of the train (6.37 km) and the car (5.45 km):

d = d_{t} + d_{c} = 6.37 km + 5.45 km = 11.82 km

Therefore, Luis traveled 11.82 km in total.

I hope it helps you!

Can anybody help me solve this? You must solve for X first.
gogolik [260]

Answer:

45 degrees

Step-by-step explanation:

angle QRS is same as (2x + 3) because it is an isosceles triangle

so, 90 + (2x+3) + (2x+3) =180 degrees

             2x+3 +2x+3=180-90

2x+2x +3+3=90

4x+6=90

4x=90-6

4x=84

x=84/4

x=21

substitute x=21 in (2x+3)

2*21+3=45

The expresion 14.42d + 12.24c can be used to find the total cost of d punds of almonds and c pounds of cashews how much does it
madam [21]

Answer:

Therefore the total cost of 3\frac{1}{2} pound of almonds and 3\frac{1}{2} pound of cashews is

y=\frac{36.05}{d}+\frac{30.6}{c}

[Where y is in $]

Step-by-step explanation:

[The unit of price is not given, I assume the unit of cost as $]

Given expression is 14.42 d + 12.24 c .

Where the amount of almond is denoted by d pounds.

and  the amount of cashews is denoted by c pounds.

The cost price of d pound of almond is $14.42.

The cost price of 1 pound of almond is \$\frac{14.42}{d}

Then the cost of 3\frac{1}{2} pound of almond is =\$\frac{ 14.42 \times3 \frac{1}{2} }{d}

                                                                 =\$\frac{36.05}{d}

Again from the given expression we get that,

The cost price of c pound of cashews is $12.24

The cost price of 1 pound of cashews is =\$\frac{12.24}{c}

Then the cost of 3\frac{1}{2} pound of cashews is =\$\frac{ 12.24 \times3 \frac{1}{2} }{c}

                                                                    =\$\frac{30.6}{c}

Therefore the total cost of 3\frac{1}{2} pound of almonds and 3\frac{1}{2} pound of cashews is

y = =\frac{36.05}{d}+\frac{30.6}{c}

[Where y is in$]
