Check whether the given value of x is a solution to the equation.

(x+4) = 20 where x = 48

Is the given value of x a solution to the equation?

Answers

Answer 1
No, because x=48 and 48+4 is 52 so 52 does NOT sum up to be 20
Answer 2
substitute x into the equation
((48)+4=20
52=20
No it is not, as 58 does not equal to 20

the school raised money for new playground equipment. They sold candy bars for 2$ each. They Sold 143 on Monday, 200 on Tuesday, and 56 on Wednesday. How Much Money did they raise?

Answers

Answer:

I think the answer is $798

Step-by-step explanation:

143×2=286

200×2=400

56×2=112

286+400+112=$798

They earned $798

The first thing you have to do in order to find your answer is add up the total amount of candy bars sold for the total 3 days. Then once you have that added up, multiply it by 2 (since they were worth 2 dollars each) and you will come up with $798 total.

Answers

Answer:

Triangle A- Right   Triangle B- Acute   Triangle C- Obtuse   Triangle D- Right

Step-by-step explanation:

Triangle A has one right angle.

An acute-angle triangle is triangle B.

The obtuse angle triangle is Triangle C.

A right-angle triangle is Triangle D

What is the way of classifying a triangle?

If a² + b² < c² then it is an acute angle triangle.

If a² + b² = c² then it is a right-angle triangle.

If a² + b² ≥ c² then it is an obtuse angle triangle.

We know angles less than 90° is called acute angle and angles greater

than 90° is an obtuse angle.

From the given diagram and mentioned angles in the triangles, we conclude that,

Triangle A is a right-angled triangle.

Triangle B is an acute-angle triangle.

Triangle C is an obtuse angle triangle.

Triangle D is a right-angle triangle.

What is the prime factorization of 88?
A.8✖11
B.2✖4✖11
C.4✖4✖11
D.2✖2✖2✖11

Answers

The answer is d
Hope this helps :)

Answer:

D. 2✖2✖2✖11

Step-by-step explanation:

 To get the Prime Factors of 88, you divide 88 by the smallest prime number possible. Then you take the result from that and divide that by the smallest prime number. Repeat this process until you end up with 1.

88 ÷ 2 = 44

44 ÷ 2 = 22

22 ÷ 2 = 11

11 ÷ 11 = 1

Again, all the prime numbers you used to divide above are the Prime Factors of 88.

The numbers 1-6 are written on slips of paper and placed in a bag. Megan draws two numbers in a row without replacement. What is the probability of Megan selecting an even number followed by a 3?

A) 1/6

B) 1/10

Answers

I’m pretty sure it would be 1/6

The probability of Megan selecting an even number followed by a 3 will be 1/10. Then the correct option is B.

What is probability?

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

Paper slips with the numbers 1-6 are collected in a bag. Without substitution, Megan draws two numbers consecutively.

The probability is given as,

P = (1/6) x (3/5)

P = (1/2) x (1/5)

P = 1/10

The probability of Megan selecting an even number followed by a 3 will be 1/10. Then the correct option is B.

Answer: 9

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle.

[tex]a^2+b^2=c^2[/tex]

[tex](\sqrt{63}) ^2+x^2=12^2\\63+x^2=144\\x^2=81\\x=9[/tex]

X=9

A squared + b squared = c squared

C is the hypotenuse (the side opposite of the right angle)

X*2 + square root of 63 squared = 12*2
Squaring 63 would cancel out with the square root. You are left with x*2 + 63 = 144. 144-63= 81. X*2=81 ; square root both sides. You are now left with x=9
