Hello,
To this question, It's only directly sum the equations:
y + y = 7x - 7x +7+19
2y = 0x + 26
2y = 26
y = 26 ÷ 2
y = 13
Now only to replace y = 13 in the equation of up or of down.
Then stay:
y = 7x + 7
13 = 7x + 7
7x = 13 -7
7x = 6
x = 6 / 7
Answer:
14 blue
Step-by-step explanation:
3/2 = 21/b
3b = 42
b = 42/3
b = 14
The equation is-
25% of the total (x) =4
Change 25% to a decimal, 0.25
0.25(x)=4
Divide 0.25 from both sides
0.25x/.25=4/.25
x= 16
Or, you could multiply 4 times 4, since 25% is a quarter.
There were 16 slices at the table.
The answer would be >, because 7.63 is greater than 7.629. :)
