14 ribbons.

7 divided by 1/2 is 14. dividing by a fraction or decimal is just like multiplying without the decimal point or numerator.

the length of a rectangle is one more than four times its width. If the perimeter of the rectangle is 62 meteres, fing the dimen

Andrews [41]

Length (L): 4w + 1

width (w): w

Perimeter (P) = 2L + 2w

62 = 2(4w + 1) + 2(w)

62 = 8w + 2 + 2w

62 = 10w + 2

60 = 10w

6 = w

Length: L = 4w + 1 → 4(6) + 1 → 24 + 1 → 25

Answer: 6 meters x 25 meters

Find the equation of a line that contains the points (3,7) and (-6, 4). Write the equation in slope-intercept form, using

NikAS [45]

Answer:

$y=\frac{1}{3} x+6$

Step-by-step explanation:

$(3,7)(-6,4)$

Step 1. Find the slope (by using the slope-formula)

m = slope

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{4-7}{-6-3}$

$m=\frac{-3}{-9}$

$m=\frac{3}{9}$

$m=\frac{1}{3}$

Step 2. Write the equation (using the slope and the points)

Here's how to do it:

Slope-intercept Formula $y=mx+b$ whrere m = slope and b = y-intercept

Plug in the slope into the Slope-intercept Formula

$y=\frac{1}{3} x+b$

Find the y-intercept (b) by using a point and substituting their x and y values

$y=\frac{1}{3} x+b$

Point: (3, 7)

$7=\frac{1}{3} (3)+b$

$7=1+b$

$b=7-1$

$b=6$

Step 3. Write the equation in Slope-intercept form

$y=mx+b$

$y=\frac{1}{3} x+6$

Tan weighs 146 pounds. Minh weighs 15 pounds more than Tan. How much does Minh weigh?

dimaraw [331]

Given parameters:

Weight of Tan = 146pounds

Unknown:

Weight of Minh = ?

Following this problem step wisely, we can derive a solvable algebraic equation;

Let the weight of Minh = M

In the second sentence, we see that Minh weighs 15pounds more than Tan;

So;

M = 15 + Weight of Tan

Since we already know the weight of Tan,

Weight of Minh = 15 + 146 = 161pounds

We clearly see that Minh's weight will be 161 pounds.

Pam needs 3 1/2 cups of sugar to make 50 cupcakes. A 5- pound bag of sugar coats $3.69. There are about 2 cups of sugar in a pou

Lorico [155]

Answer:

The answer to your question is $1.29

Step-by-step explanation:

Data

Total amount of cupcakes = 50

Total amount of sugar = 3 1/2 cups = 3.5 cups

Cost of 5-pound bag = $3.69

2 cups = 1 pound

Total cost = ?

Process

1.- Calculate the amount of pounds needed

2 cups ------------------ 1 pound

3.5 cups --------------- x

x = (3.5 x 1) / 2

x = 3.5 / 2

x = 1.75 pounds

2.- Calculate the price of 1.75 pounds

5 pounds -------------- $3.69

1.75 pounds ---------- x

x = (1.75 x 3.69)/5

x = 6.46/5

x = $1.29

3.- Conclusion

The cost of sugar to prepare 50 cupcakes is $1.29
