Answer:

7.75

Step-by-step explanation:

19 = 4a - 12

add 12 to both sides

31 = 4a

divide by 4 to isolate the variable

7.75 = a

Write an equation for the sentence below. Then solve the equation.

Romashka-Z-Leto [24]

The answer is D thirteen multiplied by h is 13h. The word "is" typically means = so 13h=104. to solve for this you want to isolate the h on one side of the equation. to do this we need to get rid of the 13 and move it on the other side of the equation. the new equation is h=104÷13. So, h=8. Hope this helps!

Please solve and show the steps. 2/3z +3 =7

USPshnik [31]

Subtract 3 from both sides:

2/3z=4

divide by 2/3 on both sides (multiple 3/2 on both sides)

z= 6

Calculate the distance between the points F=(-2,1) and A=(4,-2) in the coordinate plane. Round your answer to the nearest hundre

Anton [14]

Answer:

The distance between F and A is approximately 6.71 units.

Step-by-step explanation:

To find the distance between any two points, we can consider using the distance formula. Recall that:

$\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let F(-2, 1) be (x₁, y₁) and A(4, -2) be (x₂, y₂).

Substitute and evaluate:

$\displaystyle \begin{aligned} FA &= \sqrt{((4) - (-2))^2 + ((-2) - (1)^2} \\ \\&=\sqrt{(6)^2 + (-3)^2} \\ \\&=\sqrt{36 + 9} \\ \\ &= \sqrt{45} \\ \\ &= 3\sqrt{5}\\ \\&\approx 6.71\text{ units} \end{aligned}$

In conclusion, the distance between F and A is approximately 6.71 units.
