Answer:
The answer could be A) or D) because the zero acts as a place holder. Its a little easier to derive it if you have a bigger decimal
Step-by-step explanation:
Answer is 9
you always simplify the paranthesis first and then do the rest.
(-7)(-2) is 14 and -15 divided by 3 is -5
so you have 14+(-5) which is just 14-5
it gives you 9
Answer:
The distance when x = 6km is D = 498 KM
Step-by-step explanation:
Here, given the formula for the distance, we want to find the distance D given the value of x to be 6km
What we do simply here is to substitute the value 6km as x in the equation
The equation is
D = 4x^3 - 10x^2 -6
Substituting x = 6, we have
D = 4(6^3) -10(6^2) -6
D = 864-360-6
D = 498 km
Answer:
1. X = -2/3
2. T= 0.3125
Step-by-step explanation:
Answer: Brian should ask a price of £520 for the guitar.
Step-by-step explanation:
Given : Making cost of guitar= £325
Mark up percentage = 60%=0.60 [we divide percentage by 100 to convert into decimal]
Now , the price should be asked by Brian May for the guitar would be :
(Making cost of guitar) + 60% of (Making cost of guitar)
=(Making cost of guitar) + (0.60) x (Making cost of guitar)
= (Making cost of guitar) x (1+0.60) [By distributive property]
= (£325) x (1.60)
= £520
Hence, Brian should ask a price of £520 for the guitar.
