# 90<-30p+15 how do you solve this

*To solve an inequality, it's the same as if you were solving an equation: Isolate the desired variable to one side to solve.

Firstly, subtract 15 on both sides:

Next, you are going to divide both sides by -30. Since you are dividing by a negative, you are going to flip the inequality symbol. Your final answer will be:

In △ABC, m∠A=72°, c=61, and m∠B=16°. Find the perimeter of the triangle.

The perimeter of the triangle is about 136

### Further explanation

Firstly , let us learn about trigonometry in mathematics.

Suppose the ΔABC is a right triangle and ∠A is 90°.

### tan ∠A = opposite / adjacent

There are several trigonometric identities that need to be recalled, i.e.

Let us now tackle the problem!

This problem is about Sine Rule.

First of all, we will calculate the ∠C :

∠A + ∠B + ∠C = 180°

72° + 16° + ∠C = 180°

∠C = 180° - 72° - 16°

∠C = 92°

Next, we will use the Sine Rule to find the length of the other side of the triangle.

Finally, we can find the perimeter of a triangle with the following formula

Original price: $45.00;markdown: 22% ### Answers Answer:$35.10

Step-by-step explanation:

Original price = $45.00 Markdown = 22% Therefore, 22% × 45.00 = × 45.00 = 0.22 × 45.00 =$9.9

Now subtract $9.90 from$45.00

= $45.00 -$9.90 = $35.10$35.10 is the answer.

22% is 0.22 in decimal form
0.22×45= $9.90 markdown so 45-9.90=$35.10 is the sales price

The ratio of two numbers is 7 to 5. The sum of the numbers is 24. What are the numbers?12 and 12

14 and 10

21 and 15

18 and 6

14 and 10

Step-by-step explanation:

The ratio of the 2 numbers = 7x : 5x

The sum of the 2 numbers is 24, hence

7x + 5x = 24

12x = 24 ( divide both sides by 12 )

x = 2

7x = 7 × 2 = 14

5x = 5 × 2 = 10

Thus the numbers are 14 and 10

Lea walked 1/2 miles in 1/3 hours. How long will it take Lea to walk 21/4 miles?

1/3÷1/2=2/3
2/3×21/4=7/2
it will take her 3.5 hours
21/4 * 1/3  /  1/2
= 21/12  / 1/2
= 21/12 * 2
= 21/6
= 3 3/6
= 3 1/2

The sum of two numbers is 38. The greater number is 5 more than twice the lesser number. What is the greater of the two numbers?

Have the first number be x and the other number be y.

Write the first equation: The sum is 38:

x+y=38

Then the second equation: x is 5 more than than 2y:

x=2y+5

Take the first equation and make it y=38-x

Then substitute it in for the 2nd equation to find x:

x=2(38-x)+5

x=76-2x+5

3x=81

x=27

Then substitute that into the 1st equation to find y:

(27)+y=38

y=11

The first number (x) is greater than the second number (y) because 27 is greater than 11
