Answer 6

To solve for z, we need to isolate it on one side of the equation.

6.4 = 2z + -4

To isolate z, we can first move the -4 to the other side by adding 4 to both sides of the equation:

6.4 + 4 = 2z + -4 + 4

10.4 = 2z

Next, we can divide both sides of the equation by 2 to solve for z:

10.4/2 = 2z/2

5.2 = z

Therefore, z = 5.2.

Answer 7

To solve for v, we need to isolate it on one side of the equation.

–(v − –4) = –7

First, let's simplify the expression inside the parentheses:
v - (-4) = v + 4

Now the equation becomes:
-(v + 4) = -7

To eliminate the negative sign in front of the parentheses, we can multiply both sides of the equation by -1:
-1 * -(v + 4) = -1 * -7

This simplifies to:
v + 4 = 7

Next, we can solve for v by subtracting 4 from both sides of the equation:
v + 4 - 4 = 7 - 4

This simplifies to:
v = 3

Therefore, v = 3.

Answer 8

To solve for c, we need to isolate it on one side of the equation.

–4 = –(c − 7)

We can begin by eliminating the negative sign in front of the parentheses. To do this, we multiply both sides of the equation by -1:

-1 * -4 = -1 * -(c - 7)
4 = c - 7

Next, let's solve for c by adding 7 to both sides of the equation:

4 + 7 = c - 7 + 7
11 = c

Therefore, c = 11.

Answer 9

To solve for t, we need to isolate it on one side of the equation.

t + 14.11/–2 = 1.87

First, let's simplify the expression on the left side by dividing 14.11 by -2:

t - 7.055 = 1.87

Next, we can move -7.055 to the right side of the equation by subtracting it from both sides:

t - 7.055 + 7.055 = 1.87 + 7.055

This simplifies to:

t = 8.925

Therefore, t = 8.925.

Answer 10

My apologies for the error in my previous response. Let's correct it and solve for t correctly.

t + 14.11/–2 = 1.87

To simplify the expression on the left side, let's divide 14.11 by -2:

t - 7.055 = 1.87

Next, let's isolate t by subtracting 7.055 from both sides of the equation:

t - 7.055 + 7.055 = 1.87 + 7.055

This simplifies to:

t = 8.925

Therefore, t = 8.925.

Answer 11

To solve for b, we need to isolate it on one side of the equation.

4.69 + –2b = 16.69

First, let's start by moving 4.69 to the other side of the equation by subtracting it from both sides:

4.69 + -4.69 + -2b = 16.69 + -4.69

This simplifies to:

-2b = 12

Next, we can divide both sides of the equation by -2 to solve for b:

-2b/-2 = 12/-2

This simplifies to:

b = -6

Therefore, b = -6.
