Find the values of x and y.

Answer:

A) 49x^2-36 km

Step-by-step explanation:

Remember that speed is equal to distance divided by time. Therefore, if you multiply time with speed, then you get the distance traveled.

So, we will do (7x+6) kph multiplied by (7x-6) hours to get 49x^2-36 km.

Answer:

A.

Step-by-step explanation:

If 1 match releases 1100 joules of heat energy and we know that 1 joule = 0.239 calories. This means that 1 match releases 1100 * 0.239 calories

1 match releases 262.9 calories.

Again, if 1 match produces 262.9 calories, then

1 match = 262.9 calories

x match = 2100 calories

if we cross multiply, we have

1 match * 2100 calories = x match * 262.9 calories

x match = 2100/262.9

x match = 7.987 matches

Therefore, approximately 8 matches are needed

Answer/Step-by-step explanation:

Combine multiplied terms into a single fraction

2.7z+1.2z−6.5=0.7

2 7 / 1 0 + 1 . 2 − 6 . 5 = 0 . 7

Combine multiplied terms into a single fraction

2 7 / 1 0 + 1 . 2 − 6 . 5 = 0 . 7

2 7 /1 0 + 6 5 − 6 . 5= 0 . 7

Find common denominator

2 7 /1 0 + 6 5 − 6 . 5= 0 . 7

[tex]\frac{27z}{10} +\frac{2.6z}{10} +\frac{10(-6.5)}{10} =0.7[/tex]

Combine fractions with common denominator

[tex]\frac{27z+2*6z+10(-6.5)}{10} =0.7[/tex]

Multiply the numbers

[tex]\frac{27z+12z-65}{10} =0.7[/tex]

Combine like terms

[tex]\frac{39z-65}{10} =0.7[/tex]

Multiply all terms by the same value to eliminate fraction denominators

[tex]10*\frac{39z-65}{10} =10*0.7[/tex]

Cancel multiplied terms that are in the denominator

39z-65=10*0.7

Multiply the numbers

39z-65=7

Add 65 to both sides of the equation

39z-65+65=7+65

Simplify

39z=72

Divide both sides of the equation by the same term

[tex]\frac{39z}{39} =\frac{72}{39}[/tex]

Simplify

Answer:

88

Step-by-step explanation:

9 × 8 + [tex]2^{4}[/tex]

=> PEMDAS

so first exponent 2^{4} = 16

next multiplication

9*8 = 72

=> 72 + 16

=> 88

After solving the given expression, the value obtained from it in form of simplest fraction is equal to 5.1/8.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given data in the question,

a = 7/8

b = -7/16

c = 0.8 and

d = 1/4

And the equation is a+b+cd

7/8 + (-7/16) + (0.8)(1/4)

7/16 + 0.2

= 10.2/16

In simplest form, it is written as 5.1/8.

f(6) = 53

Step-by-step explanation:

f(x) = 10x - 7

We want to find f(6)

To do so simply substitute 6 for x in the equation

Equation: 10x - 7

x = 6

f(6) = 10(6) - 7

multiply 10 and 6

f(6) = 60 - 7

subtract

f(6) = 53

Answer:

[tex]f(x)=53[/tex]

Step-by-step explanation:

For [tex]f(x)=10x-7\\[/tex] substitute x for 6

[tex]10\cdot 6=60\\60-7=53[/tex]

[tex]f(6)=53[/tex]

To be a function each x value creates a different y value.

The x value in the problem is the same for each set but the y values are all different so it is not a function.

Answer:

Step-by-step explanation:

21 roses are white so that is 70%

so that would be 70/100 and can reduce to 7/10

and the percent of red would be 3/10

so we can do 21 divided by 7 which equals 3

then we can do 3 x 3 because 3/10 which equals 9

then you do 21 + 9= 30

so the answer is 30.

Answer:

41910.

Step-by-step explanation:

We can calculate this by first finding the sum for  k = 1 to 50 then subtracting the sum for k = 1 to 14.

We use the formula  (1/6)n(n+1)(2n+1)

So for 1 to 50 its 1/6 * 50* 51 * 101 = 42925

and for 1 to 14 it comes to 1/6*14*15*29 = 1015

So the answer is 41910.
