Use What You Know About Angles To Solve For X

Answers

Answer 1

Answer:

x = 22

Step-by-step explanation:

The combined angle is 90 degrees since it's a right angle

(x + 15) + (3x - 17) = 90

Add your common values

4x - 2 = 90

Add 2 to both sides

4x = 88

Divide each side by 4

x = 22

You separate 42 bulbs of garlic into two groups:one for planting and one for cooking. You will plant 3 bulbs for every 4 bulbs that you will use for cooking. Each bulb has about 8 cloves. How many cloves of garlic will you plant?

Answers

Answer:

144 cloves

Step-by-step explanation:

You separate 42 bulbs of garlic into two groups:one for planting and one for cooking.

We have a ratio of planting to cooking

Planting : Cooking

You will plant 3 bulbs for every 4 bulbs that you will use for cooking.

Hence: 3 : 4

The total of their proportion = 3 + 4 = 7

Hence:

The number of garlic you plant =

3/7 × 42 = 18 bulbs of garlic

The number of garlic you use to cook =

4/7 × 42 = 24 bulbs of garlic

We are also told that:

Each bulb has about 8 cloves. How many cloves of garlic will you plant?

From the calculation above , we know the number of bulbs of garlic been planted

= 18 bulbs.

Hence:.

1 bulb = 8 cloves

18 bulbs = x

x = 8 cloves × 18 bulbs

x = 144 cloves

Therefore, you will plant 144 cloves of garlic

John and Ana weight a total of 250 pounds. If John weights 130 pounds. How much does Ana weight?

Answers

Answer:

ana = 130 pounds

Step-by-step explanation:

john + ana = 250

130 + ana = 250

ana = 250 - 130

ana = 120 pounds

a rectangle is 6 times as long as it is wide. the perimeter is 140 cm. find the area of the rectangle. round to the nearest tenth if necessary.

Answers

Answer: [tex]w = 10[/tex]

Step-by-step explanation:

Our perimeter will be 140 cm and our width of the rectangle will be 6w. We will then divide 14w and 140 by 14 so we can get w by itself. Then, we will divide the perimeter by the width.

Step 1: Let 6w will be our length and let the perimeter be 140 cm.

[tex]6w, P = 140 cm[/tex]

Step 2: Perimeter means that you add up all the 4 sides of the rectangle.

[tex]P = 140 = w + w + 6w + 6w = 14w[/tex]

[tex]P = 140, 14w[/tex]

Step 3: Divide both sides 14 to get the single w variable.

[tex]\frac{140}{14} = \frac{14w}{14}[/tex]

Step 4: Simplify.

[tex]10 = w[/tex]

Step 5: Flip sides.

[tex]w = 10[/tex]

The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a retail price of $125. We need to find the wholesale (original) price of this bike. What percent of the wholesale (original) price is the retail price?

Answers

Answer:

Wholesale Price = $96.15Retail price percentage = 130%

Step-by-step explanation:

Wholesale price was marked up by 30% and became $125.

Assume wholesale price is x. Expression will be;

125 = x + (30% * x)

125 = 1.3x

x = 125/1.3

x = $96.15

Retail price percentage = 125/96.15

= 1.30

= 130%
