4(4/5) + √(4/5) + 0.2 - 5(4/5)

= 16/5 + (2√5/5) + (1/5) - 4

= (16 + 2√5 + 1 - 20)/5

= (2√5 - 3)/5 or 0.29442719

Carly tried to solve an equation step by step. 7a=28 Step 1: 7a/a = 28/7 Step 2: 7 = 4 Find Carly's mistake A: Step 1 B: Step 2

Murrr4er [49]

This are the right steps

Step 1: first you divide the both size by 7 because there is 7 a's

7a/7 = 28/7

Step 2: You solve the equation

7a/7= a. 28/7 = 4

So, the answer is a = 4

not 7 = 4

Triangle △ABC is in the first quadrant and translated along ‹ 3, 7 › and reflected across the x-axis. Which quadrant will the tr

wel

Answer:

The triangle will be in the first quadrant after the 1st transformation

The triangle will be in the fourth quadrant after the 2nd transformation

Step-by-step explanation:

* <em>Lets revise translation and reflection</em>

- Horizontal translation means move the figure to right or to left

- Vertical translation means move the figure up or down

- Reflection across x-axis reverses the figure from up the x-axis to

down the x-axis or reverses it from down the x-axis to up the x-axis

* <em>Lets solve the problem</em>

- Triangle △ABC is in the first quadrant

- It translated along ‹ 3, 7 ›

- Then reflected across the x-axis

- We need to know the image of the triangle after first transformation

lies in which quadrant and after the second transformation lies in

which quadrant

∵ The triangle in first quadrant

∵ The translation is <3 , 7>

- That means the triangle is translated 3 units to the right and

7 units up

∴ The triangle still in the first quadrant

* The triangle will be in the first quadrant after the 1st transformation

∵ The triangle reflected across the x-axis

- That means the triangle is reversed from up the x-axis to down

the x-axis

∴ The triangle is reversed to the fourth quadrant

* The triangle will be in the fourth quadrant after the 2nd transformation

7.19 divided by 58 estimate the quotients

lozanna [386]

Answer:

0.124

Step-by-step explanation:

$\frac{7.19}{58}$

To divide the numbers, we need to remove the decimal point

To remove decimal point , we multiply top and bottom by 100

$\frac{719}{5800}$

Use long division. After using decimal point at the top we can include any number of zeros with 719
