Answer:
A,C
Step-by-step explanation:
sin 2x=sin (x+x)=sinx cos x+cos x sin x=2 sin x cos x
or =2 cos x sin x
[sinx cox=cos x sin x ]
Answer:
x=924
Step-by-step explanation:
348 + 926 = x + 350
we have two 2-terms additions in both sides of the equation.
348 and 350 are two <em>similar</em> numbers then x and 926 should be really <em>close</em> numbers.
(due to commutative property of additions 348 + 926 = 350 + x)
<em>since 348 has two units less than 350, then 926 must have two units more than x, and <u>x=924</u></em>
(indirect proportionality)
Answer: k=54/79
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 16/3k from both sides.
Step 3: Subtract 5/2 from both sides.
Step 4: Multiply both sides by 12/(-79).

Ok so $2.05 + $15 = $17.05 so you want to try to spend the same amount of money in each store so what have to do is figure out the number of gallons you buy in each store i added 2 gallons for the first store so the amount would be $2.05(2) + $15= $21.15 so now to find the x in the next equation you have divide the sum by $2.35 which give you 9 gallons now you spent the same amount in each store so you paid for 11 gallons hope you give me brainliest answer lol
Answer:
1)
7 X 8 = 56
6 X 8 = 48
8 X 8 = 64
8 X 11 = 88
8 X 16 = 128
2)
If the division is left divided goes into the right then it would be:
72 divided by 3 = 24
17 divided by 3 = 5.66666
11 divided by 3 = 3.66666
9 divided by 3 = 3
216 divided by 3 = 72
If the division is right divided goes into the left then it would be:
24 divided by 3 = 8
33 divided by 3 = 11
51 divided by 3 = 51
27 divided by 3 = 9
72 divided by 3 = 24.
Step-by-step explanation:
for the first problem you multiply the left numbers by the 8 to get the right numbers and to get the left numbers you divide the right numbers by 8.
For the second problem if the division is left divided goes into the right then it would be for getting the left numbers multiply the right numbers by 3 and for getting the right numbers just divide the left by 3 but if the division is right divided goes into the left then it would be the exact same process as before but in this one if you are getting the left numbers just divide the right by and if you getting the right numbers then multiply the left numbers by 3.
ps: sorry this answer is long.
