Answer:
198
Step-by-step explanation:
27/9 becomes three and then there is no need to divide 198 by three because it is being multiplied by three
Answer:
C is the dependent variable and r is independent
Step-by-step explanation:
Adriana can ride the bus any number of times she wants. No one is stopping her from doing that so 'r' becomes an independent quantity.
Whereas, the total cost for the bus rides depends on the number of times Adriana rides the bus and the relation is given as, C=1.25r
This is because it costs $1.25 each time she rides the bus in one direction
Answer:
7 ÷ 4/5 is 8.75 as a decimal or 8 3/4 as a fraction
Answer:
The value of x for equation is 3.4
The value of y for equation is 5.2
Step-by-step explanation:
Given as :
The two linear equation are
2 x + y = 12 ........A
4 x - 3 y = 2 .........B
Now, Solving both equations , we get
3 × ( 2 x + y ) + (4 x - 3 y) = 3 × 12 - 2
Or, 6 x + 3 y + 4 x - 3 y = 36 - 2
Or, (6 x + 4 x) + (3 y - 3 y) = 34
Or, 10 x + 0 = 34
∴ x = 
i.e x = 3.4
So, The value of x for equation , x = 3.4
Put the value of x into eq A
∵ 2 x + y = 12
Or, y = 12 - 2 x
Or, y = 12 - 2 × 3.4
Or, y = 12 - 6.8
∴ y = 5.2
So, The value of y for equation , y = 5.2
Hence, The value of x for equation is 3.4 and The value of y for equation is 5.2 Answer
The gcf of 15 and 70 is 5
