Answer:
x = 8
p = -400
y = -98
Step-by-step explanation
-8x = -64
Divide both sides by -8
x = 8
50 = -(1/8)p
Divide both sides by -(1/8)
p = 50/-(1/8)
p = -400
-90 = 8+y
Subtract 8 from each side
y = -98
Tara's music teacher requires students to practice their instrument at least 9 hours each week. Tara usually spends 2.5 hours practicing on weekends.

Step-by-step explanation:
1 how many more calories should a person on a 2,000-calorie diet eat from veggies than from carbs?
2 if a person is on an 1,800-calorie diet,then how many of their calries will come from fruit?
3 a person on a 2500 calorie diet states that they ar healthier because they eat more calories from veggies. explain why this is or is not accurate
4 according to the graph above which of the following best represents the number of calories from protein a person on a 2200 calorie diet should consume
A 450
B 550
C 625
D 650
The calories from the different diets are given below.
1. 2,000 calories diet eat from veggies than from carbs is 200 calories.
2. 1,800 calories diet from fruit is 270 calories.
3. 2500 calorie diet, healthier because they eat more calories is not accurate.
4. 2200 calorie diet eat from protein is 550 calories. Then option B is correct.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
1. The calories should a person on a 2,000 calories diet eat from veggies than from carbs will be
→ 2000 × 0.35 = 700 calories
→ 2000 × 0.25 = 500 calories
→700 – 500 = 200 calories
2. If a person is on a 1,800 calories diet, then the calories will come from fruit will be
→ 1800 × 0.15 = 270 calories
3. A person on a 2500 calorie diet states that they are healthier because they eat more calories from veggies will be
→ 2500 × 0.35 = 875 calories
Because veggies have more calories than others. Thus, inaccurate.
4. The number of calories from protein a person on a 2200 calorie diet should consume will be
→ 2200 × 0.25 = 550 calories

Find the number of revolutions made by a wheel with a radius of 5 ft that traveled 633 ft. Use 3.14 for pi. Round your answer to the nearest tenth of a revolution.
A)40.3 revolutions
B)8.1 revolutions
C)19,876.2 revolutions
D)20.2 revolutions
Answer:
d
Step-by-step explanation:
1) convert ft to cm
5ft=152.4cm
633ft=19293.84cm
2) 2*3.14*152.4=975.072
3)19293.84/975.072 = 20.16rev

Determine the measures of the unknown angles in the figure.
m < APD =
m < CPE =
m < BPD =
Answer:
angle APD=115 degrees
angle CPE=25 degrees
angle BPD=65 degrees
Step-by-step explanation:
APD=180-65=115 because it is supplementary
CPE=90-65=25 because it is complementary
BPD=65 because it is an alternate angle
The measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.
What is an angle?An angle is a geometrical shape that is formed by two rays or lines, called the sides or arms of the angle, that share a common endpoint, called the vertex of the angle.
Given is a figure, we need to find the measurement of the asked angles,
m ∠APD, m ∠CPE and m ∠BPD.
So,
∠APD + ∠APC = 180° [linear pair]
∠APD = 180° - 65°
∠APD = 115°
∠CPE + ∠CPA = 90° [complimentary angles]
∠CPE = 90° - ∠CPA
∠CPE = 90° - 65°
∠CPE = 25°
∠BPD = ∠APC [vertical angles]
∠BPD = 65°
Hence, the measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.

12) Jennifer earns $78 per day working at a supermarket. She spends $8 each day at lunch and her gas to get to and from work is $6 per day. How much money will she earn in 28 days?
Answer:
$1792
Step-by-step explanation:
$78 x 28 = 2184
28 x $8 = 224
28 x $6 = 168
168 + 224 = 392
2184 - 392 = $1792
Check Work:
1792 + 392 = 2184
2184 / 78 or 2184 / 28
=78

Answer:
A. <dilation by a factor of 1/7>
Step-by-step explanation:
Rotation, reflection, and translation are "rigid" motions that preserve congruence.
Dilation does not preserve congruence. Dilation multiplies the coordinates by a dilation factor, as in the transformation of choice A.
(x, y) ⇒ (x/7, y/7) . . . does NOT preserve congruence

Answer:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...
(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts
