Answer:

LCM: 24

GCF: 4

Step-by-step explanation:

LCM: guess and check by multiplying the largest number by an integer and dividing the product by the smaller number to check. 12*2=24 ... 24/8=3 ✓

GCF: opposite the other: guess and check by dividing the smaller number by an integer and multiplying the quotient by the larger number to check.

PLS HELP ASAP!! ALGEBRA 9!! 4.29-x+36=102-2.52x+2

Andrei [34K]

Answer:

x = 29

Step-by-step explanation:

If the equation is :

4.2(9-x)+36=102-2.5(2x+2)

→distribute 4.2 and -2.5 in parenthesis

4.2(9 - x) + 36 = 102 -2.5(2x + 2)

37.8 - 4.2x +36 = 102 -5x -5

→ have terms with x = terms without x

Keep the terms you need the way they are, and move the terms you need on the other side of equal sign with changed sign.

4.2(9 - x) + 36 = 102 -2.5(2x + 2)

37.8 - 4.2x +36 = 102 -5x -5

- 4.2x +5 x = - 37.8 - 36 + 102 - 5

→ Combine like terms

0.8x = 23.2

→ Divide both sides by 0.8

x = 29

The temperature of a city changed -24 degrees Celsius over a 6 week period. Write an expression the show the average change in t

Ne4ueva [31]

Answer:

The expression is (-24) / 6 = -4degrees which means that in each week the average change in temperature was -4 degrees Celsius.

Step-by-step explanation:

Change in a quantities can as well be interpreted as rate of change which is used in many everyday problems, such as weather forecast, traveling , in science and so on.When we are talking about rate of change it's is usually in ratio such as Miles per hour or feet per second can be used in calculation involving rates of speed. It is how one quality is changing with respect to time , for instance, rate equals distance divided by time: r = d/t.

In finance rate of change is also applicable we can have Unit price which is a particular rate that compares a price to some unit of measure. Example is $64 per dozen.

Therefore, Given from the question,

The temperature of a city changed -24 degrees Celsius ,

Time =6 weeks period.

Then change is r = d/t.

= (-24) / 6

Change = (-24) / 6 = -4 degrees

This means that each week the average change in temperature was -4 degrees Celsius.
