Answer: x=3

Step-by-step explanation: First we do distributive property in the parentheses. Next we subtract both sides by 6. Lastly we divide both sides by 3. Algebraic Rules!!!

Work:

3(x+2)=15

3x+6=15

3x+6-6=15-6

3x=9

3x/3=9/3

Multiply the bracket by 3

3x+6=15

3x+6-6=15-6

3x=9

divide by 3 for 3x and 9

3x/3=9/3

x=3

Check answer by using substitution method

3(x+2)=15

3(3+2)= 15

Multiply the bracket by 3

9+6= 15

15= 15

Answer is x= 3

Diego has $11 and begins saving $5 each week toward buying a new phone. At the same time that Diego begins saving, Lin has $60 a

Nata [24]

Answer:

Let x represents the week and y represents the amount of money.

As per the given statement:

Diego has $11 and begins $5 each week toward buying a new phone.

⇒ ......[1]

It is also given that Lin $60 and begins spending $2 per week.

⇒ ....[2]

when they have the same amount.

equate [1] and [2] we get;

Add both sides 2x we get;

Subtract 11 from both sides we get;

Divide both sides by 7 we get;

x = 7

Substitute the value of x = 7 in [1] we have;

Therefore, at x= 7 week they have the same amount of money and they have the amount at that time, $ 46

I need help... Can someone help. If x equals 7, what does y equal? x = 7 y = ? 6x = 7y

klemol [59]

Y=6. you would replace x with 7 in the equation.
6(7) = 7y
42=7y

» Which pair of numbers has an LCM of 60? 2 and 12 5 and 12 6 and 12 3 and 12

Mariana [72]

Answer: 5 and 12

Step-by-step explanation:

2 and 12 is not it because 12 can be divided by 2 meaning that the LCM of those two numbers will be 12.

6 and 12 is not it because 12 can also be divided by 6 meaning that the LCM of 6 and 12 is also 12.

3 and 12 is also the same, 12 can be divided by 3 so their LCM will be 12.

With 5 and 12, 12 is not divisible by 5 so you will have to find the multiples of 5 and 12 and it will eventually be 60.

Multiples of 5: 5, 10,15,20,25,30,35,40,45,50,55,60,65

Multiples of 12: 12, 24, 36, 48, 60, 72

As it appears in both multiples, 60 is the least number that appears in both multiples so the LCM of 5 and 12 is 60.
