Answer:
Step-by-step explanation:
x+ 8/4 -x+ 5/4
= x+2+-x +5/4
Combine Like Terms:
x+2+-x+ 5/4
(x+x)+ ( 2 +5/4)
= 13/4
If a cup is a regular sized cup that is 2 deciliters, and 1 liter equals 10 deciliters, that means that 1 liter = 5 cups, which means that 3 liters = 15 cups. If it is a cup that has 0.33 dl, then the correct number would be 9 cups.
(8x+32)/4= 2x+8
2x+8=y+7 With y being the length of a side of square b
y=2x+1
Perimeter of square b: 4(2x+1)=8x+4
Or you could just do this:
32-4(7)=4 so Perimeter of b is 8x+4
Answer:
x = - 191/28
Step-by-step explanation:
14 (8x + 56) = 20
112x + 784 = 20
112x = 20 - 784
112x = - 764
x = - 764/112
x = - 191/28
Answer:


Step-by-step explanation:
Given

Solving (a): Expand
To do this, we make use of pascal triangle
When the exponent is 6, the factors are: 1, 6, 15, 20, 15, 6 and 1
As a rule, the exponent of 1 will start from 0 and then increase by 1 in each term while the exponent of 3x will start from 6 and then decrease by 1 in each term.
So, we have:

Expand



Solving (b): (0.97)^6
Rewrite as:

Express -0.03 as 3 * -0.01

So, by comparing:
and 

Recall that:

This gives:
