Answer:
Step-by-step explanation:
Direct proportion.
Distant between two cities= 11/3 * 9.7 = 106.7/3 = 35.56 km
Answer:
7 sqrt(2)= BC
7 sqrt(2)= AB
Step-by-step explanation:
sin 45 = opp / hyp
sin 45 = BC / 14
Multiply each side by 14
14 sin 45 = BC
Sin 45 = sqrt(2)/2
14 sqrt(2)/ 2 = BC
7 sqrt(2)= BC
cos 45 = adj / hyp
cos 45 = AB / 14
Multiply each side by 14
14 cos 45 = AB
cos 45 = sqrt(2)/2
14 sqrt(2)/ 2 = AB
7 sqrt(2)= AB
Remember the distributive property? It goes like x(a+b)=xa+xb... For example 3(6+7)=(3*6)+(3*7)=39
Same here
5(3x-6)-8(3x-7)
do the thing
(15x-30)-(24x-56)
Take parentheses off.
15x-30-24x+56
//WHY PLUS 56 NOT MINUS?
//because there was a minus sign outside the original parentheses, so the signs inside have to be flipped when the parentheses is taken off
//Let's simplify now
15x-24x-30+56
-9x+26
^^The answer!
Answer: x=6
Step-by-step explanation:
To solve for x, we want to isolate the variable.
[get common denominator]
[add fractions]
[combine like terms]
[multiply both sides by 8]
[subtract both sides by 14]
[divide both sides by 15]
Now, we know that x=6.
Step-by-step explanation:
Hi!
I can help you out!
16/20=4/5=8/10=32/40
Hope this can help, choose whichever fraction, they're all the same {it just depends the options you're given
Hope this helped! <3
