If n is number of miles last week then 8 multiplied by n is 8n, and then you just add 12, so 8n+12 is answer
FIRST
I solve the angles on the center (2,3,4)
∠2 is as big as 121° because they are vertical angles
∠3 is as big as ∠4 because they are vertical angles
The sum of angles on the center is 360° because they make a round of circle
121° + ∠2 + ∠3 + ∠4 = 360°
121° + 121° + ∠3 + ∠3 = 360°
242° + 2(∠3) = 360°
2(∠3) = 118°
∠3 = 59°
∠4 = 59°
SECOND
I want to find angle on the left (1) with interior angles of triangle
The sum of interior angles in triangle = 180°
∠1 + ∠3 + 48° = 180°
∠1 + 59° + 48° = 180°
∠1 = 73°
THIRD
I'm going to the right triangle. The right triangle is congruent with the left triangle. So the angles that facing each other has the same number.
∠7 = 48°
∠6 = ∠1 = 73°
FOURTH
I'm going to the upper triangle and find ∠5
The sum of interior angles in triangle = 180°
35° + ∠2 + ∠5 = 180°
35° + 121° + ∠5 = 180°
∠5 = 24°
LAST
I'm going to the lower triangle. The lower triangle is congruent with the upper triangle. So the angles that facing each other has the same number.
∠8 = 35°
∠9 = ∠5 = 24°
THE SUMMARY
∠1 = 73°
∠2 = 121°
∠3 = 59°
∠4 = 59°
∠5 = 24°
∠6 = 73°
∠7 = 48°
∠8 = 35°
∠9 = 24°
Answer:
the equation for the stated problem would be:
3x ≥ -6
Step-by-step explanation:
2x^2 + 10x = 0
we can take out x from both terms and we get:
x(2x + 10) = 0
now either x has to be equal to 0 or 2x + 10 has to be equal to zero in order for equation to be equal to 0.
one solution is x=0 as stated above
other is:
2x + 10 = 0
2x = -10
x = -10/2 = -5
Answers are x=0 and x = -5.
Total number of loaves sold = 9360 + 2640 = 12000
Number of loaves of whole wheat bread = 2640
Percentage of loaves of whole wheat sold = 2640/12000 x 100 = 22%
Answer: 22%
