0 In 20-25, insert parentheses to make each statement true. 20. 30 - 4 X 2 + 5 = 2 21. 17 – 8 – 5 = 14 22. 10 = 2-3 + 1 = 3 23. 30 – 4 x 2 +5= 57 24. 17 – 8 – 5 = 4 25. 10 = 2-3 + 1 = 1


I need to know where to place the parentheses but my teacher didn't explain it well enough for me.​

Answers

Answer:

This is pretty much trial and error,

Step-by-step explanation:

what you are doing is trying to make the question true. So if you're trying to make 30 - 4 x 2 + 5 =2 true, you need to try to put parentheses in the right place, because Wwhatever you see in parentheses you have to do first. For example, the answer to the first question is 30 - 4 x (2+5) =2. The reason is 2 + 5 = 7, and 7 × 4 = 28, and 30 - 28 is 2. To help with order of operations, remember the term Please Excuse My Dear Aunt Sally (P for parentheses, E for exponent (if you're here yet), M for multiplication, D for division, A for addition, and S for subtraction). Here are the other answers:

17 - (8 - 5) = 14

(30 - 4) × 2 + 5 = 57

17 - 8 - 5 = 4

Two numbers have a sum of 1,212 and a difference of 518.
What are the numbers?

Answers

347 and 865.

To solve this problem you set up two equations,

x+y=1212 and x-y=518.
You then get the second x by itself by adding y to both sides.
You then have x+y=1212 and x=y+518.
After this you substitute the x into the first equation and have y+518+y=1212.
Then simplify to 2y=694 and y=347

Now that y=347 you put it in the original equation. Solve and get that x=865

Answer:

B) 26

Step-by-step explanation:

Finding PH

Take the sides in proportionGP/PH = GQ/QI10/PH = 15/2410/PH = 5/8PH = 10/5 x 8PH = 16

Finding GH

GP + PH10 + 1626

If PQ || HI, then the value of GH obtained will be equal to 26. Hence, option B is correct.

What is ratio?

The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities in order to compare them.

As per the given figure in the question,

Firstly, we have to find the value of PH.

Take the sides in proportion from the given figure,

GP/PH = GQ/QI

= 10/PH = 15/24

⇒ 10/PH = 5/8

PH = 10/5 x 8

PH = 16

Now, the value of GH will be,

GP + PH

= 10 + 16

= 26

Find the area of the window shown below. Use 3.14 for pi. Round to the nearest tenth.

Answers

Answer:

A = 22.0 in²

Step-by-step explanation:

The area-of-a-circle formula is A = (pi)r², where r is the radius.  The area of a semicircle is A = (1/2)(pi)r².

In this case (semicircular window), the area is

A = (1/2)(3.14)(14 in) = 21.98 in².  To the nearest tenth, that's A = 22.0 in²

A family sets out on a road trip to visit their cousins. They travel at a steady rate. The graph shows the remaining distance to their cousins' house for each hour of the trip.

How fast are they traveling?

Answers

I think the answer is 35 km per hour because they are travelling in steady rate and the graph chart is showing the times and all

The traveling speed of A family sets out on a road trip to visit their cousins is,

⇒ Speed = 100 km / h

Given that;

A family sets out on a road trip to visit their cousins.

And, They travel at a steady rate.

The graph shows the remaining distance to their cousins' house for each hour of the trip.

We know that;

⇒ Speed = Distance / Time

Let by graph;

Distance cover by family in 3 hours = 300 km

Hence, We get;

The traveling speed of A family sets out on a road trip to visit their cousins is,

⇒ Speed = Distance / Time

⇒ Speed = 300/ 3

⇒ Speed = 100 km / h

Thus, The traveling speed of A family sets out on a road trip to visit their cousins is,

⇒ Speed = 100 km / h
