Answer:
y is equal to 4.
Step-by-step explanation:
To find this, cross multiply and then divide.
10*2 = y*5
20 = 5y
4 = y
Answer:
Let the three consecutive integers be x,x+1,x+2
ATQ
x+2(x+2)+15=4(x+1)
=3x+19=4x+4
= x=15
..... Hence. The nos. Are 15,15+1=16 and 15+2=17
Step-by-step explanation:
Hey there. To find the answer solve 8^3=512.
Count the rows and columns of each to get C as your answer.
Answer:
u just 82 + 59% = 130.38
Step-by-step explanation:
Let x be the number of racing bikes, and let y be the number of mountain bikes.
1) 140x + 110y = 26150
2) 180x + 120y = 31800
Solve for one of the variables and plug that in to the other equation:
From equation 1: 140x = 26150 - 110y
x = (26150-110y)/140
Plug this into equation 2:
180((26150-110y)/140) = 31800
Solve for y, and find that y = 85 (the number of mountain bikes).
Plug that y into either equation to find x:
140x + 110(85) = 26150
x = 120 (the number of racing bikes).
So the answer is: 120 racing bikes and 85 mountain bikes.
