Answer:
Tomas added 6 to both sides of the equation instead of subtracting 6.
Step-by-step explanation:
Tomas is making trail mix using granola and walnuts. He can spend a total of $12 on the ingredients. He buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation 2x + 6y = 12 to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy.
Given:
2x + 6y = 12
where
x = number of pounds of granola y = number of pounds of walnuts
The correct solution to the problem
x = 3 pounds
2x + 6y = 12
2(3) + 6y = 12
6 + 6y = 12
Subtract 6 from both sides
6 + 6y - 6 = 12 - 6
6y = 6
Divide both sides by 6
y = 6/6
= 1
y = 1 pound
Tomas added 6 to both sides of the equation instead of subtracting 6.
Answer:
If you take 2/3 in a calculator you get 0.6 repeating and if you take that times 1/2 you will get 0.3 repeating therefor 1/3
Step-by-step explanation:
It’s 70, 35+85=110 180-110=70
Answer:
It is D. (x + 1)^2 + (y - 3)^2 = 16.
Step-by-step explanation:
The general equation of a circle is
(x - h)^2 + (y - k)^2 = r^2 where the center is (h, k) and the radius is r.
So substituting the given values the required equation is:
(x + 1)^2 + (y - 3)^2 = 4^2.
Answer:
Step-by-step explanation:
The area for a triangle is

Our base is given as x, the height is given as 1 more than 6 times the base which looks like this: 6x + 1. We know that the area is 13, so filling in everything:

We can get rid of the denominator of 2 by multiplying it on both sides to get:
and simplifying a bit:

Now we can move over the 26 and put the expression into standard quadratic form by setting it equal to 0:
which is choice C
