Answer:
x =30
Step-by-step explanation:
in order to evaluate the solution 4/5=20/(x-5)?
solution
the first step to take is to cross multiply
4/5=20/(x-5)
we have,
5 x 20 = 4 ( x -5)
100 = 4x - 20
combine the like terms
100+20 = 4x
120 = 4x
divide both sides by the coefficient of x
120/4 = 4x/4
30 = x
x =30
therefore the value of x in the expression 4/5=20/(x-5)? is 30
Answer:
Base = 5 cm
Height = 20 cm
Step-by-step explanation:
Points to remember
Area of triangle = bh/2
Where b - base of triangle
h - Height of triangle
<u>To find the Height and Base of given triangle</u>
It is given that,area of a triangle piece of stained glass is 50 centimeters
the height of the triangle is four times the base
h = 4b
Area = bh/2
50 = (b * 4b)/2
100 = 4b²
b² = 100/4 = 25
b =√25 = ±5
b = 5 then h = 4b = 4 * 5 = 20
Base = 5 cm and Height = 20 cm
Answer:
D and E
Step-by-step explanation:
hello,
a function cannot have two different value for the same x
so D (4 different values for x = 1 ) and E (two different values for x = 6 ) are wrong
hope this helps
Answer:
Solve for x
x=14
Step-by-step explanation:
by simplifying both sides of the equation, then isolating the variable.
Answer:
1 4/5 (Proper Fraction)
1 8/10 (Proper Fraction, but Not simplified)
18/10 (Improper Fraction)
Step-by-step explanation:
change to improper fraction
22/10 - 4/10 = 18/10
Simplify
18/10 = 1 8/10
Simplify again
1 4/5
