Answer:
Average decrease in car's value per year = 1800$
Explanation:
The worth of car bought by Mr. Solan = 30000$
Reduction of car's price = 5400$
Number of years considered for measuring reduction of car's price = 3 years.
Average of values = Total of the values/ Number of values.
Average reduction per year = Total reduction/ Number of years.
= 5400/3 = 1800$
So average decrease in car's value per year = 1800$
Answer:
The value of m in the expression is 5
Step-by-step explanation:
Given expression as :
3 + ( 4 + 5 ) = ( 3 + 4 ) + m
Or, 3 + ( 9 ) = ( 7 ) + m
Or, 12 = 7 + m
∴ m = 12 - 7 = 5
Hence The value of m in the expression is 5 Answer

Answer:
sure. x=12
Step-by-step explanation:
firstly! we know that the two sections equal 90 degrees (because a right angle is 90 degrees). so, take both of those sections, and put them equal to 90 in an equation.
it would look like this...
(x+42) + (3x) = 90
which is the same as...
<u>x + 42</u> + <u>3x</u> = 90. ignore the parenthesis. they're just for clarification. then we will solve for x!
add similar things together! see x and 3x? those are similar because they have x in them. (HOWEVER! if it's something like x² and x, do not add them together!) x is the same as 1x, by the way. so 1x + 3x. ignore the Xs and add the numbers. it becomes 4x
4x + 42 = 90
move 42 to the other side by minusing it on both parts of the equation!
4x = 90 - 42
4x = 48
divide 48 by 4 so x is alone. there ya go
