The answer is 7.00=.75x+1.29
X represents number of bagels Nick can buy
1c. New Value=64.8 and Decrease=15.2
1e. Original Value= $70 and Decrease=$21
1f) Original Level=11 and New value=44
Answer: C) 28
Explanation:
The triangles are congruent, so the corresponding pieces are congruent. Specifically the angles on the right side are congruent, as shown by the tickmarks they have in common.
Set those two expressions equal to one another. Solve for x.
2(x+2) = 60
2x+4 = 60
2x = 60-4
2x = 56
x = 56/2
x = 28
Answer:
R = 101
S = 131
Step-by-step explanation:
First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.
T=180-128
T=52
You also know that all angles in a triangle equal to 180
Use that to find angle S
180 = R+S+T
180 = 79 + S + 52
180 - 79 - 52 = S
49 = S, exterior S = 180-49 = 131
Exterior R = 180 - 79 = 101
Now add all your exteriors
8 + 6 + 9 + 12 + 4x / 5 = x Original Problem.
25 + 4x / 5 = x Addition.
25 + 4x = 5x Multiply each side by 5.
25 = x Subtract 4x from each side.
x = 25 Switch equation around.
Answer: x = 25
