If you take a number times by 3 then add 5 you get the same as if you took the number times by 7 then subtract 8 what is the number

3 1/4

Step-by-step explanation:

3x+5=7x-8

Subtract 5 from both sides

3x=7x-13

Subtract 7 from both sides

-4x= -13

Divide by -4

X= 13/4

SIMPLIFIED: 3 1/4

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
