Two triangles are similar if they have:
<span>all their angles equalcorresponding sides are in the same ratio</span>
But we don't need to know all three sides and all three angles ...two or three out of the six is usually enough.
There are three ways to find if two triangles are similar: AA, SAS and SSS:
Answer:
$75 - $15 - $20 = $40
Step-by-step explanation:
Given that:
Money owed by Preston to his brother = $15
Money owed by Preston to his sister = $20
Total money earned by Preston = $75
Now, the money is paid back that he owed to his sister and brother.
To find:
The expression to represent the amount of money left with Preston after clearing all his dues?
Solution:
Once Preston pays back the money that he owed to his brother and sister, he will not have all $75 left with him.
He will have lesser amount of money.
Money left with Preston = Total money earned by Preston - Money owed to brother - Money owed to sister
Putting the values given as per the question statement, we get:
Money left with Preston = $75 - $15 - $20 = $40
Therefore, the expression to represent the amount of money left with Preston =<em> $75 - $15 - $20 = $40</em>
Answer:
1/21
Step-by-Step Explanation:
Let's solve your equation step-by-step.
3(1−5x)=2(3x+1)
Step 1: Simplify both sides of the equation.
3(1−5x)=2(3x+1)
(3)(1)+(3)(−5x)=(2)(3x)+(2)(1)(Distribute)
3+−15x=6x+2
−15x+3=6x+2
Step 2: Subtract 6x from both sides.
−15x+3−6x=6x+2−6x
−21x+3=2
Step 3: Subtract 3 from both sides.
−21x+3−3=2−3
−21x=−1
Step 4: Divide both sides by -21.
-21x/-21=-1/-21
x=1/21
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (6, 4)
m =
=
= - 1
He was camping at an elevation of 18,492
the following day, he descended (he came down) 2,516 ft....
so ur expression would be : 18,492 - 2,516 <==
and ur answer would be : The elevation of the 2nd campsite is :
15,976 ft <==
