The entrance to our school has a height of 10.5 feet. There are approximately 30.5 centimeters in 1 foot. What is the height of the entrance in centimeters?​

Answer:

x+3y=-1

Step-by-step explanation:

y=3x-2 so m=3 old slope

the new slope must be -1/3 (opposite reciprocal of the old slope).

y-y0=m*(x-x0)

y-2=-1/3*(x-(-7))

y-2=-1/3x-1/3*7

y-2=-1/3x-7/3

3y-6=-x-7

The standard form for linear equations in two variables is Ax+By=C.

x+3y=6-7

x+3y=-1

Answer:

5(x+3)

Step-by-step explanation:

Find the Greatest Common Factor (GCF).

GCF = 55

2 Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

5(\frac{5x}{5}+\frac{15}{5})5(

Factor 5 out of 5x + 15.

5 (x + 3)

Answer:

y= -2/5 x -4

Step-by-step explanation:

So the equation is y=mx+b. Where m=slope and b=y-intercept. To find b, you would see at what point does the line cross the y axis. That would be at -4 so, -4 would be the b or y-intercept. To find m, you would take two points on the line and use this equation:

m=(y2 - y1 )/(x2 - x1)

If you were using the points, (-10,0) and (0, -4) the equation would be:

m=(-4-0) / (0+10)

So, m= -2/5

The equation of the line would end up being:

y= -2/5 x -4

Answer:

3.375

Step-by-step explanation:First convert the 2 1/4 and the 1 5/8

then you just add it with the 0.5 or just use a calculator  

2 1/4 = 9/4

1 5/8= 13/8

okay now do this ---> 0.5 + 9/4 +13/8 =3.375

Answer: 2b-5=11

Step-by-step explanation: 2b is equivalent to 2 times, and 5 less is the -5

Answer:

7

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

This is the answer because:

1) Mean - add all the numbers and divide by with how many numbers you added.

2) The numbers are: 7,9,10,5,8,3,7

3) 7 + 9 + 10 + 5 + 8 + 3 + 7 = 49

4) 49 ÷ 7 = 7

Therefore, the answer is 7.

Hope this helps! :D

Answer: y=-6=-3(x-4)

Step-by-step explanation:

Answer:

x = 16

Step-by-step explanation:

Problem: -3/8(x-24)+x=19

Distribution:

-3/8x + 9 + x = 19

5/8x = 19 - 9

5/8x = 10

x = 10 • 8/5

x = 16

The relationship between the cost of cookies and the number of cookies is

a proportional relationship.

Correct response:

The function of the given graph for the cost of cookies at store A is found as follows;

The graph is a straight line passing through the origin, therefore, the equation is of the form;

y = m·x

The cost of 2 cookies = $0.5

Therefore;

The cost of 1 cookie at store A = $0.5 ÷ 2 = $0.25

Therefore, the cost of y cookies = 0.25·x

Where;

x = The number of cookies

The equation representing the cost y for x cookies in store B in dollars is given as follows;

y = 0.30·x

Therefore, the cost of 1 cookie at store B = $0.30 × 1 = $0.30

Therefore;

Step-by-step explanation:

Answer:

17.0 ft

Step-by-step explanation:

Let h be the height of the base of the window from the ground, L be the length of the ladder = 18 ft and d be the distance of the ladder from the wall = 6 ft. Now, these three lengths form a right-angled triangle with the length of the ladder, L as the hypotenuse side.

So, using Pythagoras' theorem,

L² = h² + d²

So, h = √(L² - d²)

Substituting the values of L = 18 ft and d = 6 ft, we have

h = √((18 ft)² - (6 ft)²)

= √(324 ft² - 36 ft²)

= √288 ft²

= 16.97 ft

≅ 17.0 ft
