Answer:

x=7/2

Step-by-step explanation:

Answer:

x=7/2

Step-by-step explanation:

x-(2x+1)=8-(3x+2)

x-2x-1=8-3x-2

-x-1=6-3x

+x on both sides

-1=6-2x

-6 on both sides

-7=-2x

7=2x

÷2 on both sides

7/2=x

Answer:

There was no change in the length of June's scarf, that is, the length of it remained the same.

Step-by-step explanation:

Since Sue knitted a scarf for her friend June that was also 4 feet long and, after a month, the length of June's scarf could be represented by the expression 3/3 x 4, to determine how did the length of June's scarf change you must perform the following calculation:

Month 1 = 4

Month 2 = 3/3 x 4 = 1 x 4 = 4

Therefore, as can be seen, there was no change in the length of June's scarf, that is, the length of it remained the same.

Answer: x = 110

Explanation:

We can see that both the sides are equal because of the lines on the sides of the triangle. That means that the angle on the other side is also 35, we also know that the total amount of degrees in a triangle is 180

So now we can do this equation:

35 + 35 + x = 180

70 + x = 180

x = 110

Step-by-step explanation:

[tex]180 - (35 \times 2) = \\ = 180 - 70 = \\ = 110[/tex]

The sum of internal angles of a triangle is 180 and we have a triangle with 2 lengths that are the same. We can say that also the other angle is 35,so the result is 110

C is 25

Step-by-step explanation:

Because 25+38=63 and 63/7 is equal to 9.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The value of c in the expression (c + 38) / 7 = 9 is 25.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

(3x + 2)/ 3 is an expression.

2x + x + 4x is an expression.

We have,

(c + 38) / 7 = 9______(1)

We will solve for c.

From (1).

(c + 38) / 7 = 9
Multiply 7 on both sides.

7 x (c + 38) / 7 = 7 x  9

c + 38 = 63

Subtract 38 on both sides.

c + 38 - 38 = 63 - 38

c = 25

Thus,

The value of c in the expression (c + 38) / 7 = 9 is 25.
