<h3>
Answer: B. x = 6</h3>
==========================================================
Explanation:
Since the vertical lines are parallel, this means the alternate exterior angles shown are congruent.
Set them equal to each other and solve for x.
15(x+2) = 120
15x+30 = 120
15x = 120-30
15x = 90
x = 90/15
x = 6
Or we could have the steps like this
15(x+2) = 120
x+2 = 120/15
x+2 = 8
x = 8-2
x = 6
Answer: she uses 2 eggs for one batch of brownies and 4 eggs for one batch of cookies.
Step-by-step explanation:
Let x represent the number of eggs that she uses for one batch of brownies.
Let y represent the number of eggs that she uses for one batch of cookies.
Last month, she made 2 batches of brownies and 3 batches of cookies. This means that
2x + 3y = 16 - - - - - - - - - -1
The month before, she baked 1 batch of brownies and 1 batch of cookies, which required a total of 6 eggs. This means that
x + y = 6 - - - - - - - - - - - - - 2
Multiplying equation 1 by 1 and equation 2 by 2, it becomes
2x + 3y = 16
2x + 2y = 12
Subtracting, it becomes
y = 4
Substituting y = 4 into equation 2, it becomes
x + 4 = 6
x = 6 - 4 = 2
Answer:
200 + (10 y)
Step-by-step explanation:
martin 200 * 5 and divide by 100 =10 per year interest 240 =M
cary 200 + 10=210 =C
200 + (10 y)
Answer:
$1.20
Step-by-step explanation:
3.6/3=1.2
you would divide for the unit rate or in other words simplify it.
Step-by-step explanation:
solution ? you mean where both lines cross each other ?
these are 2 parallel lines (same slope, but different y-intercept), so they never cross each other.
there is no solution.
formally :
3x - 1 = 3x + 4
-1 = 4
this is wrong. therefore there is no solution.
