Answer:

Total crackers on the plate are 12

Step-by-step explanation:

Manuel ate crackers = $\frac{1}{3}$

His brother ate crackers = $\frac{1}{4}$

Crackers left on the plate = 5

We need to find how many crackers were there on the plate.

Let x be the total crackers on the plate

So, we can write the equation

$x-\frac{1}{3}x-\frac{1}{4}x=5$

Because 1/3 and 1/4 crackers are eaten and 5 are left so, we subtract 1/3x and 1/4x from x and equal it to 5

$\frac{12x-4x-3x}{12}=5\\\frac{12x-7x}{12}=5\\\frac{5x}{12}=5\\x=\frac{5*12}{5}\\x=12$

So, we get x = 12

Therefore, total crackers on the plate are 12

0.75(8+e)=2-1.25e0.75(8+e)=2−1.25e what is e

vodka [1.7K]

Answer:

$e=-2$

Step-by-step explanation:

Given: $0.75(8+e)=2-1.25e$

Step 1: Distribute the Left-Hand Side

$0.75*8+0.75*e=2-1.25e\\6+0.75e=2-1.25e$

Step 2: Collect like terms

$0.75e+1.25e=2-6\\2e=-4$

Step 3: Divide both sides by 2

$e=-2$

Two joggers start from opposite ends of an 8 mile course running towards each other. One jogger is running at a rate of 4 mph. T

Licemer1 [7]

Answer:

48 minutes

Step-by-step explanation:

Given: The distance between A and B is 8 miles. Speed of one jogger is 4 miles per hour, and speed of other jogger is 6 miles per hour.

To find: After how many minutes will the joggers meet, if they are running towards each other.

Solution:

Let both the joggers will meet after t hours, at point P between A and B.

We know that $Distance=speed\times time$

Let the jogger running at a speed of 4 miles per hour starts from point A.

So,

$AP=speed\times time$

$AP=4\times t$

$AP=4t$

Let the jogger running at a speed of 6 miles per hour starts from point B.

So,

$BP=speed\times time$

$BP=6\times t$

$BP=6t$

We have,

$AP+BP=AB$

$\implies4t+6t=8$

$\implies10t=8$

$\implies t=\frac{8}{10}$

$\implies t=0.8$

So, both the joggers will meet after 0.8 hours or $0.8\times60=48$ minutes.

Hence, the joggers will meet after 48 minutes.

The school secretary was making copies of flyers to send home with all the students in the school.She used 1.33 packs of paper i

ASHA 777 [7]

Ok so
had 7 to begin with
used 1.33
then used 3.4

so
7-1.33-3.4 is the question

7=1+4+2 so
7-1.33-3.4=1+4+2-1.33-3.4=1+(2-1.33)+(4-3.4)=1+(0.67)+(0.6)=1.67+0.6=2.27

2.27 stacks of paper left
