Answer:
the actual pressure is 31.09
Complete question:
What is the actual pressure when Ali's gauge shows 33.58
Step-by-step explanation:
Given,
Ali's tyre presser gauge show a reading 8% higher than the actual pressure.
Ali's gauge shows 33.58.
Let the actual pressure be x.
According to problem,
{ [If 8% increasing of a no ⇒ The number becomes =
of the number}
x= 
x=31.09
Therefore, the actual pressure is 31.09
Answer:
B. 20x^4-39x^3+26x^2-6x
Step-by-step explanation:
(5x^2-6x+2)*(4x^2-3x)
20x^4 -15x^3 -24x^3 + 18 x^2 +8x^2 - 6x
20x^4 -39x^3 + 26x^2 - 6x
Answer:
if 8 people take 10 hours then
1 people 10 / 8 = 1.25 hours
then 14 people =
14 * 1.25 = 17.5 hours
B is correct as -4 is smaller than 7
d is correct as -30 is smaller than -18
e is correct as -3 is bigger than -8
Answer:
7. x = 3
Step-by-step explanation:
To find the value of x, use the triangle sum property. Every triangle has interior angles which add to 180 degrees. To solve, add the expressions and numbers together then set equal to 180. Then use inverse operations to solve for x.
7. 20x - 9 + 10x + 9 + 90 = 180 Subtract 90 from both sides.
20x - 9 + 10x + 9 = 90 Add -9 + 9 = 0
20x + 10x = 90 Add like terms 20x + 10x = 30x
30x = 90 Divide both sides by 30.
x = 3
Repeat this process for each problem.
