Answer:

M = 10

Step-by-step explanation:

To take an answer for this question, simply look back at linear equations.

(m/5)-8=-6

Fit’s get rid of -8 by adding 8 on both sides.

(m/5)-8+8=-6+8

So now simplified down we get:

(m/5)=2

Now we can get rid of the ‘/5’ by multiplying it by 5 on both sides.

m = 2 x 5

m = 10

Casey can buy 3 sandwiches and 5 cups of coffee for $26. Eric can buy 4 sandwiches and 2 cups of coffee for $23. How much does o
dolphi86 [110]
Let's identify what we are looking for in terms of variables.  Sandwiches are s and coffee is c.  Casey buys 3 sandwiches, which is represented then by 3s, and 5 cups of coffee, which is represented by 5c.   Those all put together on one bill comes to 26.  So Casey's equation for his purchases is 3s + 5c = 26.  Eric buys 4 sandwiches, 4s, and 2 cups of coffee, 2c, and his total purchase was 23.  Eric's equation for his purchases then is 4s + 2c = 23.  In order to solve for c, the cost of a cup of coffee, we need to multiply both of those bolded equations by some factor to eliminate the s's.  The coefficients on the s terms are 4 and 3.  4 and 3 both go into 12 evenly, so we will multiply the first bolded equation by 4 and the second one by -3 so the s terms cancel out.  4[3s + 5c = 26] means that 12s + 20c = 104.  Multiplying the second bolded equation by -3:  -3[4s + 2c = 23] means that -12s - 6c = -69.  The s terms cancel because 12s - 12s = 0s.  We are left with a system of equations that just contain one unknown now, which is c, what we are looking to solve for.  20c = 104 and -6c = -69.  Adding those together by the method of elimination (which is what we've been doing all this time), 14c = 35.  That means that c = 2.5 and a cup of coffee is $2.50.  There you go!

What is the answer for 6k-9=-15
docker41 [41]
Simplifying 6k + -9 = -15 Reorder the terms: -9 + 6k = -15 Solving -9 + 6k = -15 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + 6k = -15 + 9 Combine like terms: -9 + 9 = 0 0 + 6k = -15 + 9 6k = -15 + 9 Combine like terms: -15 + 9 = -6 6k = -6 Divide each side by '6'. k = -1

ASAP HELP HIGH POINTS <br> find the value of x.
Westkost [7]

Answer:

x ≈ 4.2 (nearest tenth)

Step-by-step explanation:

The chord of length 4 is the base of an isosceles triangle with height of 3.7 and sides equal to the radius (x).

An isosceles triangle comprises two right triangles, each with:

  • base = 2 units
  • height = 3.7 units
  • hypotenuse = x units

Therefore, to find x use Pythagoras' Theorem:  a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

⇒ a² + b² = c²

⇒ 2² + 3.7² = x²

⇒ x² = 17.69

⇒ x = √(17.69)

⇒ x = 4.2 (nearest tenth)
