Amigo hay una aplicación llamada math papá es un calculadora es muy buena si la sabes usar
-9-8(1+4h) = -17. We need to solve for h.
First, use the distributive property for 8(1+4h):
8(1+4h) = 8*1 + 8*4h = 8 + 32h
So -9-8(1+4h) = -17
-9 - (8+32h) = -17
-9 - 8 - 32h = -17
-17 - 32h = - 17
Add 17 on both sides to have the variables on a side and the numbers on the other:
-17 - 32h + 17 = -17 + 17
-32h = 0
divide both sides by -32 to get the variable h alone and its value on the other side:
(-32h)/-32 = 0/-32
h = 0.
So -9-8(1+4h) = -17 for h = 0.
You can recheck your answer (very important):
-9 - 8(1+4h) = -9 -8(1+4*0) = -9 - 8(1+0) = -9-8*1 = -9-8 = -17
The answer has been approved.
Hope this Helps! :)
Answer:
11,200
Step-by-step explanation:
Given that the lcm of a and b is 40 then a and b are factors of 40. All the multiples of 40 as sets are 1 and 40, 2 and 20, 4 and 10, 5 and 8. Of all these, only 5 and 8 would give a lcm of 40.
Let a = 5 and b = 8 as such,
7 a^2 = 7 * 5^2 = 175
7b^2 = 7 * 8^2 = 448
Then the lcm of 7 a^2 and 7b^2
= 11,200
Answer:
- When x = 2, y = 0
- When y = 5, x = 4
Step-by-step explanation:
<h2>PART I: Value of y, when x = 2</h2>
<u>Given information</u>
x = 2
<u>Given expression</u>
2y - 5x + 10 = 0
<u>Substitute values into the expression</u>
2y - 5(2) + 10 = 0
<u>Simplify by multiplication</u>
2y - 10 + 10 = 0
2y = 0
<u>Divide 2 on both sides</u>
2y / 2 = 0 / 2
-----------------------------------------------------------------
<h2>PART II: Value of x, when y = 5</h2>
<u>Given information</u>
y = 5
<u />
<u>Given expression</u>
2y - 5x + 10 = 0
<u>Substitute values into the expression</u>
2(5) - 5x + 10 = 0
<u>Simplify by multiplication</u>
10 - 5x + 10 = 0
20 - 5x = 0
<u>Add 5x on both sides</u>
20 - 5x + 5x = 0 + 5x
20 = 5x
<u>Divide 5 on both sides</u>
20 / 5 = 5x / 5
