First distribute the 1/5 through the parentheses.
1/5 (3 + 2z) - 4z = -3
3/5 + 2/5z - 4z = -3
subtract 3/5 from each side
2/5z - 4z = -3 - 3/5
combine like terms
-3 3/5z = - 3 3/5
z = 1
Answer A
You can answer this problem in two different ways: the first being (17 - 5) * x, and the second being 12 * x.
Answer:
c < - 6
Step-by-step explanation:
Given
3(2c - 8) - 10c > 0 ← distribute and simplify left side
6c - 24 - 10c > 0
- 4c - 24 > 0 ( add 24 to both sides )
- 4c > 24
Divide both sides by - 4, reversing the inequality symbol as a consequence of dividing by a negative quantity.
c < - 6
Since -1.5 is greater than -3.5, we can write a problem where someone has more than the other.
Sara has $-1.5 in her bank account while Luke has $-3.5 in his bank account. Who has a greater amount in their bank account?
Answer: -3.5 < -1.5
Best of Luck!
Step-by-step explanation:
Area of one side of the shed
5*4=20
she painted 4 sides so 20*4 =80
Triangle that is part of the pyramid as the roof of the shed has a side of 5. Using the Pythagorean theorem,
we need to find the square root of 18.75 to find the height of the triangle which is
that is the height
(base x height) /2 is the formula for a right triangle. there are 2 of these right triangles per side of the roof. so we need to multiply the numbers by 8
this number gives us 43.30127019
we can finally add that number to 80 to get the total surface area Zoe painted which is 123.3012702
