Answer:
y=1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6=2(y+2)
6=(2)(y)+(2)(2)(Distribute)
6=2y+4
Step 2: Flip the equation.
2y+4=6
Step 3: Subtract 4 from both sides.
2y+4−4=6−4
2y=2
Step 4: Divide both sides by 2.
2y/2 2/2
Answer: A.) 10x + 15
Step-by-step explanation:
You would distribute (multiply) the 5 to the 2x which would then make it 10x and you would distribute (multiply) the 5 to the 3 which would then make it 15. Because the 5 is a positive number the sign stays the same.
Therefore, 10x + 15 is your answer.
Answer: x= 55 because 60 + 65 =125 and 180 - 125 = 55
Step-by-step explanation:
The sum of three angles in any triangle is 180. Therefore you add the two angles that you have and use that number to subtract it by 180. Then you will have your answer. Also you can get the answer to y by subtracting the value of x from 180.
Answer:
A, (13/3 x 5/13)
Step-by-step explanation:
So first, you should change the mixed numbers into improper fractions. To convert, just multiply the whole number by the denominator and add the numerator. Do that to both fractions and you should get 13/3 ÷ 13/5. Since you need to switch to multiplication, switch the sign and flip that fraction/ That asnwer is 13/3 x 5/13. Hope that helps! :)
√52 -√13 +√117
= 2√13 -√13 +3√13
= 4√13 . . . . matches selection A
_____
√52 = √(4·13) = (√4)(√13) = 2√13
√117 = √(9·13) = (√9)(√13) = 3√13
