Solve for k. Is there one solution or many? 4 - 2k = -5( k + 7) *Please Help*

First, you should use the distributive property of multiplication to simplify the right side of the equation.  If you did this correctly, your equation should be 
4-2k= -5k-35.  You are trying to get the variable alone on one side of the equation.  So, you should add 5k to both sides.  If you did this correctly, your equation should be
4+3k= -35.  You need to keep the 3k alone on the left side of the equation, so you should subtract 4 from both sides.  If you did this correctly, your equation should be 
3k= -39.  The coefficient for k (which is 3) is currently being multiplied.  To undo multiplication, we have to divide, so you should divide both sides by 3.  If you did this correctly, then you should have your answer, k= -13.

Your final answer is k= -13.

What value of the variable makes the statement true? m+4 = –2.8 a. –6.8 b. –1.2 c. 1.2 d. 6.8

The value of the variable that makes the statement true is 

a) -6.8

This is because if you plug it back into the equation, you get -6.8 +4 = -2.8.  Then, if you combine like terms on the left side of the equation, you get -2.8= -2.8, which is a true statement.

x = 3

33 photos can be put in a 4(3) to 7(3) ratio

Triangle ABC has vertices of A(–8 ,8), B(6, 2), and C(–2, 1). Find the length of the median from C in triangle ABC a. √17 b. 4 c. 5 d. √65

The length of the median from vertex C is equal to √17.  As a median of a triangle is a line segment joining a single vertex to the midpoint of the opposite side of the triangle. In this case, the median will be from vertex C to the mid-point of the triangles side AB. Thus, we can work out the length of the median from vertex C by using the Midpoint formula; M(AB) = (X∨1 + X∨2) /2 ; (Y∨1 + Y∨2) /2 . Giving us the points of the midpoint of side AB, which can be plotted on the cartesian plane. to find the length of the median from vertex C, we can use the distance formula and the coordinates of the midpoint and vertex C , d = √(X∨2 - X∨1) ∧2 + (Y∨2 - Y∨1)∧2.

9+8=17 what number sentence shows the commutative property of addition

By definition we have:

In mathematics, the commutative property or commutativity is a fundamental property that has some operations according to which the result of operating two elements does not depend on the order in which they are taken.

This is fulfilled in ordinary addition and multiplication: the order of the addends does not alter the sum, or the order of the factors does not alter the product.

We have then that the commutative property for this case is:

9 + 8 = 8 + 9 = 17

Answer:

A number sentence that shows the commutative property of addition is:

9 + 8 = 8 + 9 = 17

Solve 12 - 4x = 8 Really bad at algebra, please help :) XD

Remember, whatever you do to one side of the equation you have to do to the other.  The end goal of this is the solidify the variable on one side of the equation.

So, you start with 12 -4x=8.  You want to try and get the variable alone on one side, so you would subtract 12 from both sides, resulting in the equation

-4x=-4  Next, to continue to get the variable alone, you would have to undo the coefficients multiplication by dividing both sides by -4.

So, you get x=1 as your answer.

What are three equivalent ratio for 12/14

For this case we have the following expression:

 \frac{12}{14}

What we must do is rewrite this expression in an equivalent way.

To do this, we multiply the numerator and the denominator of the fraction by the same factor.

We have then:

For k = 1/2:

 \frac{12}{14}*\frac{\frac{1}{2}}{\frac{1}{2}} = \frac{6}{7}

For k = 2:

 \frac{12}{14} *\frac{2}{2} = \frac{24}{28}

For k = 3:

 \frac{12}{14} *\frac{3}{3} = \frac{36}{42}

Answer:

Three equivalent ratio for 12/14 are:

 \frac{6}{7}

 \frac{24}{28}

 \frac{36}{42}

Lionel wants to buy a belt that costs $22 he also wants to buy some shirts that are on sale for $17 each he has $80 what inequality can you write to find the number of shirts he can buy? Identify what your variable represents

Cost=quantity times cost per one

so he wants to buy a belt (1 belt=1 times cost per belt=1 times $22=$22)
he also wants to buy some shirts (some=unknown=x so x times cost per shirt=x times $17=17x)
x=number of shirts
he has 80 dollars
when you buy something, it is a loss so

80-(22+17x)>0 since he has to have more than or equal to zero since he cannot have negative dollars
the inequality is 80-(22+17x)>0

Kylie borrowed a book from a library. The library charged a fixed rental for the book and a late fee for every day the book was overdue. The expression below shows the charges Kylie paid for the book when she returned it x days after the due date: 2 + 0.25x What does the constant term of the expression represent? (1 point) A. The late fee for the book B. The fixed rental for the book C. The number of books borrowed D. The number of days the book was overdue

Answer:

B. The fixed rental for the book

Step-by-step explanation:

The library charged a fixed rental for the book and a late fee for every day the book was overdue.

2 +0.25x  shows the charges Kylie paid for the book when she returned it x days after the due date.

So, the constant term is the fixed rental.

As 0.25 is teamed up with x that is the number of days. So, 2 is the fixed rental charge.

Hence, option B is correct.

Write two subtraction equations to show how to find 15 - 7

Solution:

We need to find 15-7 using two subtraction equation.

First we split 15 and 7 as addition form.

Split 15 = 10 + 5

Because sum of 10 and 5 is 15

Split 7 = 5 + 2

Because sum of 5 and 2 is 7

Now we substitute into original expression.

(10 + 5) - (5 + 2)

Now we open the parentheses

10 + 5 - 5 - 2

We can see two positive number and two negative number.

Now we move one positive and one negative number together

10 - 5 + 5 - 2

Now we close in parentheses.

(10 - 5) + (5 - 2)

Two subtraction equation:

10-5  and  5-2
