The number of cookies Natalie can bake varies directly with the time she
spends baking. She can make 3 dozen cookies in 0.5 of an hour. How many
dozen cookies can she make in 5 hours?

Please help fast!!

Answers

We already know that 0.5 of an hour, or half of an hour, is 30 minutes. We also know that 3 dozen equals 36. With this information, we can conclude that Natalie can make 72 cookies in one hour. 72 times 5 is 360. 360 divided by 12 is 30, so, Natalie can bake 30 dozen, or 360, cookies in five hours.

the answer would be 10 dozen cookies

4(3+2x) + 2 = 46 , solve for x I need help I'm a bit confused

Answers

Answer:

x=4

Step-by-step explanation:

4(3+2x)+2=46

12+8x+2=46

12+8x=44

8x=32

x=4

Answer:

4

Step-by-step explanation:

You need to start with the 2x inside the parenthesis

If you put 4 in place of x you get 8

8+3=11

then because there isnt any sign between 4 and the parenthesis you multiply

4x11=44

then its easy

44+2=46

i-solve the fraction 315+79 (show all steps)
​

Answers

Answer:

Step-by-step explanation:

step 1 Address input parameters & values.

Input parameters & values:

The fraction number = 315/79

step 2 Write it as a decimal

315/79 = 3.9873

3.9873 is the decimal representation for 315/79

For Percentage Conversion :

step 1 To represent 3.9873 in percentage, write 3.9873 as a fraction

Fraction = 3.9873/1

step 2 multiply 100 to both numerator & denominator

(3.9873 x 100)/(1 x 100) = 398.73/100

398.73% is the percentage representation for 315/79

Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y = 15.

y = 3x −24y = 3x −24

y = 3x + 24

y = -3x + 24

y = -3x - 24

Answers

Step-by-step explanation:

let eqn be y = mx + b.

3y = x - 15

y = 1/3x - 5

perpendicular means product of grad = -1

hence m = -3.

sun (8, 0):

8 = -3(0) + b

b = 8

therefore, equation if the line is y = -3x + 8
