Answer:
x = 41 and y = 76
Step-by-step explanation:
Answer:
Step-by-step explanation:
The problem statement tells us ...
8x = y +3
7x = y -4
Subtracting the second equation from the first gives ...
x = 7
Then ...
y = 7x +4 = 7·7 +4 = 53
There are 7 people, and 53 coins are required for purchase.
Answer:
Step-by-step explanation:
first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm
a = 48
b= 30
Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]
= 1/2*30√( 48² - 1/4×30²)
=1/2*30√ (2304 -225)
=684sq cm
cost required to make umbrella= 10*684*5
= 3<em>4200</em>

Answer:
4(x+1)/(4x+5)
4(x+1)/(5-4x)
4(x-(-1))/(4x+5)
Step-by-step explanation:
The numerators in the fractions must equal to 0, or else the expressions won’t have the result of 0.
4(x+1)
4(-1+1)
4(0)
= 0
4(x-(-1))
4(-1-(-1))
4(-1+1)
4(0)
= 0
The expressions with the numerator as 0 have the result of 0.
