Answer:
x = 40 1/2
Step-by-step explanation:
The hash marks tell you the triangles are similar and the smaller one is 1/2 the size of the larger one. Then x is half the length of the corresponding segment marked 81.
x = 81/2
x = 40 1/2
___
You may have to write it as 81/2 or as 40.5. Sometimes the answer needs to be in a particular form.
Answer:
36
Step-by-step explanation:
12 x 6 = 72 / 2 = 36 because the area of a triangle is base times height divided by 2
9.95×4=39.80
12.95×2=25.90
15.95×2=31.90
39.80+ 25.90+31.90=97.60
97.60×.18=17.56
97.60+17.56=$115.16 without tax and 18% gratutity
I Tired To Explain It As Best As I Could.
Isolate the variable by dividing each side by factors that don’t contain the variable.
24 = x • 30
Use The Commutative Property To Reorder The Terms
24 = 30x
Swap The Sides Of The Equations
30x = 24
Divide Both Sides Of The Equations By 30
30x ÷ 30 = 24 ÷ 30
Any Expression Divided By Itself Equals 1
x= 24 ÷ 30 or x =24/30
Reduce The Fraction With 6
x = 4/5
Exact Form:
x = 4/5
Decimal Form:
x = 0.8
