I think I can bravely ignore the Freudian slip and solve this one.
-- If the mean of 5 tests is 90, then all 5 scores add up to (5 x 90) = 450
-- The sum of her first 4 scores is (95+ 90 + 85 + 95) = 365
-- If she has one more test to average 90, then she needs
to score (450 - 365) = <u>85</u> on it.
That looks like choice 'G '.
Answer:
m∠1 = 25° (opposite angles are congruent)
m∠2 = 87° ⇒ 180 - (25 + 68)
m∠3 = 68° ⇒ 180 - (87 + 25)
Hope this helps!
Answer:
49
Step-by-step explanation:
First you must do x times 6, x is really just 1. After you do that, you times it by 7.
Answer: The correct factors are
(x-1) and (x+2)
Step-by-step explanation:
Step one :
To factorize the equation
x²– x – 2=0
First we look for numbers that when multiplied will result to the constant term and when added will result to the second term (1x, - 2x)
Step two :
We replace the second term with these factors we have
x²–(x-2x)–2=0
x²–x+2x–2=0
Factoring the expression we have
x(x–1)+2(x–1)=0
Hence the factors will be
(x-1) and (x+2)
