35 Percent of 70 is 24.5
We assume, that the number 70 is 100% - because it's the output value of the task. We assume, that x is the value we are looking for. If 70 is 100%, so we can write it down as 70=100%. We know, that x is 35% of the output value, so we can write it down as x=35%. <span>Now we have two simple equations: 1.)70=100% 2.)x=35%</span>where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that: 70/x=100%/35% Now we just have to solve the simple equation, and we will get the solution we are looking for.
Answer:
-4 = ?
Step-by-step explanation:
<u>Step 1: Substitute -1 for x</u>
7x^3 + 5x^2 - 2 = ?
7(-1)^3 + 5(-1)^2 - 2 = ?
7(-1) + 5(1) - 2 = ?
-7 + 5 - 2 = ?
-4 = ?
Answer: -4 = ?
If "x" is a multiplication sign:

Answer: A
Step-by-step explanation:
3x² - 10x + 5 = 0
a = 3 b = -10 c = 5
Δ = b²- 4ac = 100 - 4.3.5 = 40 > 0 => have 2 solutions
=> x = 
or x =
