Answer:

84 is 7 x n.

n = 84 ÷ 7

n = 12

Step-by-step explanation:

You can solve the problem by using <em>algebraic expressions</em> in looking for the value of n.

Let n be<em> the no. of families in City B that have a dog.</em>

<em>City A is 7 times as many families with a dog than City B</em>. You can express this as: City A = 7 x n

Since you know that City A has 84 families owning a dog. Then you can express this as: 84 is 7 x n or 84 = 7 x n.

Let's get the value of n.

84 = 7 x n

n = $\frac{84}{7}$ or n = 84 ÷ 7

n = 12

There are 12 families in City B that have a dog.

PLEASE HELP URGENTLY!!!!¡!!!!!!¡

<h3>There are 3 answers: Choice A, Choice D, Choice F</h3>

Explanation:

2 & 1/2 = 2.5

10 + (-2.5) can be represented by starting with 10 and then dropping by 2.5, which is what choice A is saying

or we can start with -2.5 and add on 10. This works because we can add numbers in any order, example: 2+3 = 3+2 = 5. So starting with -2.5 and adding on 10 is represented by choice D's and choice F's examples

The graph of the function y=25 - x what is the domain of the function

lakkis [162]

The domain of a function is defined as the set of values of x that will give out a real value of y, a "real" number is basically a number that can be expressed as itself instead of as a symbol or a calculation, for example -4 would be a real number as we can simply express it as -4, however √-4 would not be a real number as it would be expressed as 2i. For the function y=25-x all values of x will result in a real number therefore we say domain of f(x) is x∈R, or simply saying "the domain of the function y=25-x is all real values of x" will probably suffice.

I need help to evaluate the sin0 cos0 and tan0

Dmitry [639]

Answer:

$\sin{\theta}=\frac{3}{5}, \cos{\theta}=\frac{4}{5}, \tan{\theta}=\frac{3}{4}$

Step-by-step explanation:

by triple pythagoras we get the hypotenuse is 10,

by definition of sin, cos, and tan we get the answer above with simplified .
