If a = 3 what is the value of b in the equation 2a+b=13? And can you explain?
Answer:
b=7
Step-by-step explanation:
Plug 3 into a since a=3.
2(3)+b=13
Then solve for 2(3)
6+b=13
Now isolate the b, so move the 6 to the other side. (Basically subtract 6 from both sides)
b=13-6
b=7

Answer:
3⅞ is the answer to the question.
Step-by-step explanation:
The ten lightest tomatoes are in ¼, ⅜, ½, ⅝ and ⅞.
In ¼, there are 3 tomatoes, so that would be “¼×3=¾”.
In ⅜, there are 2 tomatoes, so that would be “⅜×2=¾”.
In ½, there are 3 tomatoes, so it would be “½×3=3/2”.
In ⅝, there is 1 tomato, so it would be “⅝×1=⅝”.
In ⅞, there is 1 tomato, so that would be “⅞×1=⅞”.
Now add all together:
¾ + ¾ + 3/2 + ⅝ + ⅞
= 5+5+7+6+8/8
= 31/8
= 3⅞

i did the math
4x-6+4=2x+10
Find X
math + me = -100 IQ
Answer:
x=6
Step-by-step explanation:
The equation we start with is
4x-6+4=2x+10
First combine like terms
4x-2=2x+10
Next subtract 2x from both sides so that the variable is only on the left side
2x-2=10
Now add 2 to both sides to isolate your variable
2x=12
Finally divide both sides by 2 to find your answer
x=6
