Answer:

Option B. 44 is the correct answer

Step-by-step explanation:

Let l be the number of large pizzas and s be the number of small pizzas

Then according to the given statement the equations will be:

[tex]l+s = 100\ \ \ Eqn\ 1\\11l+7.5s = 848\ \ \ Eqn\ 2[/tex]

From equation 1

[tex]l = 100-s[/tex]

Putting in equation 2

[tex]11(100-s)+7.5s = 848\\1100-11s+7.5s = 848\\-3.5s+1100 = 848\\-3.5s = 848-1100\\-3.5s = -252\\\frac{-3.5s}{-3.5} = \frac{-252}{-3.5}\\s = 72[/tex]

Putting s=72 in equation 1

[tex]l+72 = 100\\l = 100-72\\l = 28[/tex]

How many more small pizzas means we have to find s-l

So,

s-l = 72-28 = 44

Hence,

Option B. 44 is the correct answer

Answer:

  m = -1/2

Step-by-step explanation:

The slope is the ratio of "rise" to "run". The "rise" is the vertical distance between the two points. The "run" is the corresponding horizontal distance.

Vertical distances are positive in the "up" direction, and horizontal distances are positive in the "right" direction for this purpose. Here, the rightmost point is below the leftmost point, so the "rise" is negative.

  slope = m = rise/run = -1/2

The slope is ...

  m = -1/2

Answer:  t = -22

Step-by-step explanation:

Using the slope-intercept form, substitute the values from the first coordinate and the given slope to calculate the value of b.

y = mx + b

2 = (-4)(-1) + b

2 = 4 + b

2-4 = b

b = -2

Then substitute the value of b and the values from the second coordinate to calculate t

t = (-4)(5) -2

t = -20 -2

t = -22

Answer:

y = -3x

Step-by-step explanation:

Slope-intercept form:

Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]

Given points: (-2, 6), (2, -6)

(2, -6) = (x1, y1)

(-2, 6) = (x2, y2)

To write the equation in y = mx + b form, we need to know the slope(m) and the y-intercept(b). To find the slope, input the two given points into the slope formula:

[tex]\frac{6-(-6)}{-2-2}[/tex]

Simplify:

6 - (-6) = 6 + 6 = 12

-2 - 2 = -4

[tex]\frac{12}{-4} = -\frac{3}{1} =-3[/tex]

The slope of the equation is -3. To find b, we can input the value of the slope and one point (in this example I'll use (2, -6) into the equation:

-6 = -3(2) + b

-6 = -6 + b

0 = b

The y-intercept is 0. Now that we know the slope and y-intercept, we can write the equation:

y = mx + b

y = -3x + 0

y = -3x

The equation written in slope-intercept form is y = -3x.

Answer:

When Jose plays his guitar, the friction between his fingers and the strings allows him to pluck the strings. The friction creates some heat and the vibration of the strings creates the sound. The original amount of energy he applies to the strings is 1000 joules. The energy of the vibrating strings is measured and is found to be 800 joules.

Answer:

Step-by-step explanation:

1st diagram is vertically opposte angles.

so,

a)

3x + 5 = 5x-57

3x - 5x = -5 - 57

-2x = -62

2x = 62 (cancle both the - in both sides)

x= 62/2

x=31

2nd diagram(beside to 1st diagram) both the equation lies under linear pairs. so,

b)

4x+ 150 + 2x = 180°

6x + 150 = 180

6x = 180-150

6x = 30

x=30/6

x = 5

then,

(CI. 1-119 ) below that atement,

a)

both are in alternative pairs so,

x+15=102

x=102-15

x=87

b) both are vertically opposte angles.

so,

x+21 = 7x - 3

x - 7x = -21 - 3

-6x = -24

6x = 24

x= 4  (cancle both the - in both sides)

c)

both are in linear pair so,

3x+8 +  2x + 2 = 180°

5x + 10 = 180

5x = 180 - 10

5x = 170

x=170/5

x= 34

Answer:

2 x ? = 7 1/2 and ? x 2 = 7 1/2

Step-by-step explanation:

This is the answer because it didn't show the answer so all you have to figure out is the multiplication problem that goes with the division problem. So 2 x ? = 7 1/2 and ? x 2 = 7 1/2 you don't have to include the answer all you have to include is where the answer will do if you DID have the answer. These two are correct because the multiplication number can go in any order.

I know this might not be the best step-by-step explanation ever but I truly tried but the answer is correct.

The value of 'r' in the expression 24(34 + r) = 1200 is 16.

There are three types of basic arithmetic laws of operation.

Commutative law for addition and multiplication states,

a + b = b + a.

a×b = b×a.

Distributive law states,

a(b ± c) = ab ± ac.

Associative law states,

a + (b + c) = (a + b) + c.

Given, An expression 24(34 + r) = 1200.

First, we'll distribute LHS,

24×34 + 24×r = 1200.

816 + 24r = 1200.

24r = 1200 - 816.

24r = 384.

r = 384/24.

r = 16.

Answer:

w=14

Step-by-step explanation:

Let's solve your equation step-by-step.

710−35w=570−25w

Step 1: Simplify both sides of the equation.

710−35w=570−25w

710+−35w=570+−25w

−35w+710=−25w+570

Step 2: Add 25w to both sides.

−35w+710+25w=−25w+570+25w

−10w+710=570

Step 3: Subtract 710 from both sides.

−10w+710−710=570−710

−10w=−140

Step 4: Divide both sides by -10.
