Answer:
No
Step-by-step explanation:
The variables are different in both problems. In 2×+7=27, it's 10, while in the other problem, it's 9.
27 doesn't equal 28.
Answer:
First row: 5(1)-4; 1; (1,1)
Second row: 5(2)-4; 6; (2,6)
Third row: 5(3)-4; 11; (3,11)
Step-by-step explanation:
Plug in the value of x to get the value for u then write the coordinates. So first value of x is 1 so put a 1 where the x is in this equation 5x -4. 5(1) - 4 =1 so the value of y is 1. So when x is 1 y is equal to 1 (1,1). Do the same for 2 and 3.
Answer:
Step-by-step explanation:
For a:
ax = c - by
a = (c - by)/x
For x:
ax = c - by
x = (c - by)/a
For b:
by = c - ax
b = (c - ax)/y
For y:
by = c - ax
y = (c - ax)/b
So all you have to do is divide the fractions. you would write 7/15 in your calculator, and boom you have the answer. or, you can just divide it by pencil and paper, which is harder. 4/5=0.8
