a. 4/7 + 3/8 = 32/56 + 21/56 = 53/56

b. 2/5 + 5/8 = 16/40 + 25/40 = 41/40 = 1  1/40

c.  3/8 + 2/10 = 15/40 + 8/40 = 23/40

d. 4/5 + 2/6 = 24/30 + 10/30 = 34/30 = 1 4/30 = 1 2/15

e. 5/6 + 2/9 = 15/18 + 4/18 = 19/18= 1 1/18

f. 2/15 + 5/12 = 8/60 + 25/60 = 33/60 = 11/20

Distance Traveled and Gas Left in Tank Distance Traveled (in miles) 0 90 180 270 Amount of Gas Left in Tank (in gallons) 15 12 9 6 How many gallons of gasoline does the car have left after it has traveled 330 miles?

Answers

Answer:

4 gallons of gasoline the car has left after it has traveled 330 miles.

Step-by-step explanation:

We are given with the following data of Distance Traveled and Gas Left in Tank below;

   Distance Traveled (in miles)       Amount of Gas Left in Tank (in gallons)

                 0                                                            15

                90                                                           12

               180                                                            9

               270                                                           6

               330                                                           ?

As we can see from the table that for every 90 miles of distance traveled, there has been a reduction of 3 gallons of gas which is left in the tank, i.e;

From 90 to 180 - Gas reduced from 12 to 9

This means that in 1 gallon of gas, the distance traveled is =  [tex]\frac{90}{3}[/tex] = 30 miles

So, from distance 270 to 300, the amount of Gas Left in Tank = 6 - 1 = 5 gallons

From distance 300 to 330 miles, the amount of Gas Left in Tank = 5 - 1 = 4 gallons

Hence, 4 gallons of gasoline is left after the car has traveled 330 miles.

Answer:

what is your fav movie or show on netfix

Step-by-step explanation:

Answer:

[tex] \boxed{\sf Time \ taken \ (t) = 100 \ s} [/tex]

Given:

Distance (d) = 48 km = 4800 m/s

Speed (s) = 48 m/s

To Find:

Time taken (t)

Step-by-step explanation:

Formula:

[tex]\boxed{ \bold{ Speed \ (s) = \frac{Distance \ (d)}{Time \ (t)}}}[/tex]

Substituting value of s & d in the equation:

[tex] \sf \implies 48 = \frac{4800}{t} \\ \\ \sf \implies t = \frac{4800}{48} \\ \\ \sf \implies t = 100 \: s[/tex]

[tex] \therefore[/tex]

Time taken (t) = 100 s

carlos wants to buy some new video games. each game he buys costs $36. help carlos by writing an equation that represents his total price.

Answers

36 dollars multiplied by the number of games he buys will equal the price.

Example:

Let's say he bought 3 games.

36 × 3 = 108

So, in this case, he bought three games using $108 .

if john gets 1 apple and already has 20 in a basket how many do you have in total.

Answers

Answer:

21

Step-by-step explanation:

the reason it is 21 is because u have 20 then u add 1 so it is 21 20+1=21

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

John already has 20 apples. If John gets 1 more apple, he would have 21 apples in total.

The word gets means addition. 20 plus 1 equals 21.

John has 21 apples after he gets another apple.

Ok technically I would have 0 apples since I didn't receive any only John did.

Find the point P that partitions the line segment AB given the ratio.
A (3, 6) B(4, 3) with the ratio 2:1

(11 over 3,4)


(4,11 over 3)


(5, 8)


(10, 12 over 5)

Answers

Answer:

(11/3, 4)

Step-by-step explanation:

To calculate the coordinates of the point that partitions the line segment in the given ratio, we shall be using the internal division formula.

Mathematically, that is ;

= {(mx2 + nx1/(m+n), (my2 + ny1)/(m + n)}

m and n represents the ratios 1:2

(x1, y1) represents the coordinates of A

(x2,y2) represents the coordinates of B

From the question, let’s list out the individual values;

m = 2

n = 1

x1 = 3

x2 = 4

y1 = 6

y2 = 3

Substituting these values in the equation, we have;

(2(4) + 1(3)/(1+2) , (2(3) + 1(6)/(1 + 2))

= (8 + 3)/3 , (6 + 6)/3)

= (11/3, 12/3)

= (11/3 , 4)

Answers

Question:

Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26.

What is the solution set of this problem?

Answer:

[tex]x \leq -21[/tex]

Step-by-step explanation:

Given

Represent the number with x

So:

[tex]5 * (x + 27) \geq 6 * (x + 26)[/tex]

Required

Determine the solution set

[tex]5 * (x + 27) \geq 6 * (x + 26)[/tex]

Open Both Brackets

[tex]5 * x + 5 * 27 \geq 6 *x + 6 * 26[/tex]

[tex]5x + 135 \geq 6x + 156[/tex]

Collect Like Terms

[tex]5x - 6x \geq 156-135[/tex]

[tex]- x \geq 21[/tex]

Multiply both sides by -1

[tex]x \leq -21[/tex]

Hence, the solution set is [tex]x \leq -21[/tex]

Samantha conjectures that for x < -1, it is true that x5 - 2 > x. Is her conjecture correct? Why or why not?

Answers

Answer:

  The conjecture cannot work for any negative numbers, It works for x > 1.3.

Step-by-step explanation:

An odd power preserves the sign. For |x| > 1, the power increases the magnitude. For x < 0, adding -2 only increases the magnitude more. A negative number of larger magnitude will not be "greater than" the reference. It will be "less than."

It only takes a counterexample to show the conjecture is incorrect.
