6(x + 2) = 2(x + 10)
6x + 12 = 2x + 20
6x - 2x = -12 + 20
4x = 8
x = 8/4
x = 2
3(y - 4) + 2 = 5y - 28
3y - 12 + 2 = 5y - 28
3y -10 = 5y - 28
3y - 5y = 10 - 28
-2y = -18
y = -18/-2
y = 9
5(2z - 3) - 3z = 3(z + 3)
10z - 15 - 3z = 3z + 9
7z - 15 = 3z + 9
7z - 3z = 15 + 9
4z = 24
z = 24/4
z = 6
Answer: 2/3
Hope this helps you
When you're adding fractions with two different denominators, the best thing to do is to find a common denominator;
In this case, 4 and 8 are both multiples of 8, and therefore, you've got to double the first fraction.
Doubling the first fraction gives you 2/8 and 3/8. You've then got to add these together, and this gives you 5/8 (as you only add the numerators)
As you're looking for what is left, you have to do 8/8- 5/8 (once again, only subtracting the numerators)
8/8- 5/8= 3/8
Therefore, 3/8 of the muffins are left.
Hope this helps :)
Answer:
150 units
Step-by-step explanation:
first, find 1 square
5 x 5 = 25
there are 6 total squares so 25 x 6 = 150
So the surface area should be 150 units
25% can be made in to 100% by multiplying it by 4.
Therefore, we can find the answer by multiplying 80 by 4.
80 * 4 = 320
