Since its adding and subtracting just add the coefficients of similar terms (coefficient is the number in front, term is the coefficient and variables, similar terms are terms that have the same variables)
3ab-9ab+7ab
3-9=-6: -6ab+7ab
-6+7=1: 1ab or ab :)
Answer:
sin(2x)/cos x = 2sin x*cos x/ cos x = 2 sin x = 2
sin x = 1
x = pi/2
but cos pi/2 = 0
so the given equation is indeterminate for x = pi/2
Step-by-step explanation:
Answer:
X = 11.5
Step-by-step explanation:
Check your work: 6 x 11.5 - 9 = 60
(it’s 60 because the triangle is congruent.)
Answer:
125
Step-by-step explanation:
25 × 5 = 125
x/5 = 25 × 5 = 125
x = 125
To solve this problem, first we need to find the number of peanuts, cashews, and almonds in the bag...
Total nuts=144
The ratio of cashews to peanuts to almonds can be shown as:
cashews:peanuts:almonds
2:3:7
Now lets add up the numbers in the ratio.
2+3+7=12
So, for every 12 nuts in the bag, 2 are cashews. For every 12 nuts in the bag, 3 are peanuts. For every 12 nuts in the bag, 7 are almonds.
Now lets divide the total number of nuts (144) by the sum of the ratio (12).
144/12=12
Now we can solve for the number of every type of nut in the bag...
Cashews=12*2=24nuts
Peanuts=12*3=36nuts
Almonds=12*7=84nuts
Now we can answer the problem:
Peanuts-cashews=
36-24=12 nuts
Answer: There are 12 more peanuts than cashews.
