Zack used these steps to solve this equation:

Three-fourths y + 5 = negative three-fourths y minus 9. Step 1: StartFraction 6 Over 4 EndFraction y + 5 = negative 9. Step 2: StartFraction 6 Over 4 EndFraction y = negative 14. Step 3: (StartFraction 6 Over 4 EndFraction) StartFraction 6 Over 4 EndFraction y = negative 14 (StartFraction 6 Over 4 EndFraction). Step 4: y = negative 21.

When Zack checked his solution, it didn’t work. What was his mistake?

A tree cast a 30 1/2 ft shadow at the time of day when a 2ft stake casts a 7 2/3 ft shadow.Estimate the height of the tree.

Answers

Answer:

The tree is about 8 feet.

Step-by-step explanation:

7 2/3 = 7.6 as a fraction.

30 1/5 = 30.5 as a fraction.

Know, we must divide 30.5 by 7.6.

30.5 ÷ 7.6 = 4 when rounded to the nearest whole number.

Since we know that the stake is 2 feet, we must multiply this by 4, since the other shadow is 4 times the amount of the stake.

2 x 4 = 8

This means the tree is about 8 feet.

The tree is about 8 feet

Please show your work and explain how!
Do it quickly please

Answers

Answer: hope this helps <3

x=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(7x−2)=60

(5)(7x)+(5)(−2)=60(Distribute)

35x+−10=60

35x−10=60

Step 2: Add 10 to both sides.

35x−10+10=60+10

35x=70

Step 3: Divide both sides by 35.

=35x/35

=70/35

Answer:

5(7X-2)=60

First distribute the 5 so the new equation is 35x-10=60

Then add 10 on both sides                                   +10   +10

                                                                         ___________

The new equation is 35x= 70

Then you divide by 35 on both sides to get X by itself

35x=70

35     35

The 35's cancel out leaving X by itself

70 divided by 35=2

x=2 is the final answer

What is the radius and diameter of the following circle? 4.2cm Please help

Answers

Answer:

The radius is 4.2 and the diameter is always twice the amount of the radius so its 8.4.  

Step-by-step explanation:

Answer: R = 4.2cm and D = 8.4cm

Step-by-step explanation: The diameter of a circle is the full line across the circle. The radius of a circle is half of its diameter. The line shown go's halfway through the circle so its the radius. To find the diameter you multiply the radius by 2.

Points (−6, 3) and (−6, −3) on the coordinate grid below show the positions of two dogs at a park: A coordinate plane is shown. There is a point at negative 6, 3 labeled Dog 1. There is a point at negative 6, negative 3 labeled Dog 2. Which statement best describes the relationship between the positions of the two players? Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different. Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the y-coordinates of Dog 1 and Dog 2 are different. Dog 1's position is Dog 2's position reflected across the x-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different. Dog 1's position is Dog 2's position reflected across the y-axis; only the signs of the x-coordinates of Dog 1 and Dog 2 are different.

Answers

Okay (-6,3) is dog one. Remember that. And (-6,-3) shows the position of the two dogs at the park. Both dogs positions are reflected across the Y-axis. But they are a little different from each other, the dogs of course. So the y-axis is the same but going across the x-axis is different. I know the answer to this question and it’s actually really easy. The answer would be (0,0). The reason for this is, is because two things can’t reflect across the y-axis, and x-axis at the same time. It’s a trick question. Brainliest?

The ratio of a drawing to an object is 6 cm: 40 cm. If the length of the drawing is 36 cm, what is the actual length of the object?

Brainleast? I mean if u give me an answer and an explanation pls.

Answers

Answer:

240

Step-by-step explanation:

If the length of the drawing is 36cm, then we divide 36 by 6, which then equals 6...

Since we changed the 6,  we have to change the 40...

40 x 6 = 240

so the ratio is 36:240 and the object's length equals 240cm

The actual length of the object is 240.

Every time the total number of parents call 3 people, the number of parents tripled in every round.

3 to 9 to 27 to 51 to 153 to 459

Since 153 and 459 are between 5 and 6 rounds, the phone calls will stop between those 2 rounds.
