Answer:
1 3/40
Step-by-step explanation:
1 1/4 +1 1/5 +7/8= 3 13/40
3/4 .3= 2 1/4
3 13/40 - 2 1/4
They are algebraic symbols or known as unknown number. There is no true value for them. The value of algebraic symbols are based on equations
ie. 1+x = 2
First, we isolate the x by canceling the +1 FROM BOTH SIDES(Balance method) by -1 ON BOTH SIDES.
1+x-1 = 2-1
So we are left with the x on the left side, and a single number on the right side. Therefore, our calculation is complete.
x = 1
More complex cases would be
2y-3 = 45
First, we need to isolate the algebraic symbol, which is 2y (yx2) by +3 ON BOTH SIDES
2y-3+3 = 45+3
2y = 48
WE ARE NOT DONE! 2y=48 is still an equation. Therefore, to isolate the y, we need to divide BOTH SIDES by 2
2y/2 = 48/2
y = 24
There is no true or absolute or definite value for algebraic symbols like x,y,z,a,c,t,h,d etc. They are used to represent unknown numbers.
Hope this helped!
Answer:
(-10,0) is the X intercept
(0,-45) is the Y intercept
Step-by-step explanation:
The x intercept is where it meets on the x axis, the y intercept is where it intercepts on the y axis
Answer: B. 25%
Step-by-step explanation:
64-48 = 16
16/ 64= 0.25
0.25 x 100 = 25%
