Answer 2

Answer:

When x = -3 is given, all you need to do is substitute and check if the answers in LHS and RHS are equal.

2x+4=8+x

2(-3)+4=8+(-3)

USE FOR MASTERY Number of attempts allowed: 1 Write two rational numbers a/b and c/d, where a, b, c, and d are the digits 2, 3, 4, or 5, such that no digit can be used more than once and that the two rational numbers are the greatest distance apart on the number line. Explain how you got this answer.

Answers

Answer:

We want to craft:

a/b and c/d

where a, b, c and d can be 2, 3, 4 and 5.

Such that the distance in the number line between these two numbers is maximized.

Then we want one number to be really small, and the other to be really large.

Remember two things:

for numbers like a/b.

if a is smaller than b, then a/b is smaller than 1.

Now, if a is larger than b, then a/b is larger than 1.

And two things,

1/10 = 0.1

10/1 = 10

So when the numerator is larger, the distance displaced in the number line is larger.

Then we want to have:

a number where the numerator is the largest option and the denominator is the smallest option:

a/b = 5/2

And the two remaining options in such way that the numerator is smaller than the denominator:

c/d = 3/4.

The distance between these two numbers is:

D = 5/2 - 3/4 = 10/4 - 3/4 = 7/4.

the product of 2 more than a number and 10 is 36 more than 8 times the numbe. whats the number?​

Answers

Answer: 8

Step-by-step explanation:

let x = the number

(x + 2)*10 = 8x + 36

10x + 20 = 8x + 36

2x = 16

x = 8

Rewrite 56 + 32 as the product of the GCF and a sum.

Answers

Answer:

8(7 + 4)

Step-by-step explanation:

The GCF of 56 and 32 is 8 , thus

56 + 32 = 8(7 + 4 )

56 + 32 = 88

8(7 + 4) = 8 × 11 = 88

A isn't parallel but B is

Step-by-step explanation:

I believe A isn't parallel because it's supposed to have the same number but they're one off from each other

B is parallel because when you add the numbers they equal 180 and since they're opposite they'd have to equal 180 in order to be parallel

The highest temperature recorded in the town of Westgate this summer was 100°F. Last
winter, the lowest temperature recorded was -1°F. Find the difference between these
two extremes.

Answers

Answer:

101  

Step-by-step explanation:

100- (-1) NEGATIVE MINUS NEGATIVE CANCEL OUT ON EACH OTHER AND GIVE POSITIVE: 100 + 1 = SO THE ANSWER IS  101^F

The difference between these two extreme temperatures is of

101° F.

We have the highest temperature recorded in the town of Westgate which is equal to 100°F. Last winter, the lowest temperature recorded was -1°F.

We have to find the difference between these two extremes.

What is Temperature ?

Degree of hotness or coldness measured on a definite scale is called Temperature. When the temperature of the body is high it is called hot body and when it is low it is called cold body.

According to question, we have -

Highest temperature recorded = 100°F

Lowest temperature recorded = -1°F

Let the the difference between these two extreme temperatures be x. Then -

x = Highest temperature recorded - Lowest temperature recorded

x = 100 - (- 1) = 101° F

Hence, the difference between these two extreme temperatures is of

101° F.
