8n + 8 =-56 its a two step equating help please
Answer:
n = -8
Step-by-step explanation:
Original Equation:
8n + 8 = -56
Subtract 8 from boths sides.
8n = -64
Divide both sides by 8
n = -8
Hope this helped :)
Please consider Brainliest :)
Step-by-step explanation:
its -8
8n + 8 = 56
8n + 8 - 8 = 56 - 8
8=−64
8n/ 8 -= -64
8n / 8 = -64 / 8
simplified = n = - 8
n equals -8

9. During training, a hurdler wants to raise the height of the hurdles from the high school standard of 39 inches to the
NCAA standard of 42 inches. His best race from last season included a clear over a 39-inch hurdle that was modeled by
h(t) = (-0.0251)(1-25), where t is time (in tenths of a second) after his lead leg left the track and h is the height (in feet).
If he runs as well as his best race last year, will this hurdler clear the new height? Why or why not
Answer:
Something doesn't make sense. The time when his height is 0 is time t=0 and t=25.
The vertex would be halfway in between at time t=(0+25)/2 = 12.5 seconds.
But plugging that in, we get a height of:
3.90625 inches
I think you must have a typo... let's try this equation instead:
h(t) = (-0.25t)(t - 25)
In that case, the maximum at h(12.5) is 39.0625 inches.
Answer:
No, the function for his height has him just barely clearing 39 inches. He can't clear 42 inches.
10
No, according to the function for his height, he only just clears 39 inches. He is unable to jump 42 inches.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

What is the value of x? What is the value of y?
Answer:
x = 45/2y = 10Step-by-step explanation:
Both angles that have the "x" variable are the same and both angles that the "y" are the same since they are congruent meaning they are the same angle measure.
Solve for x.
6x - 5 = 8x - 50
~Add 5 to both sides
6x = 8x - 45
~Subtract 8 to both sides
-2x = -45
~Divide -2 to both sides
x = 45/2
Solve for y.
2y + 30 = 3y + 20
~Subtract 30 to both sides
2y = 3y - 10
~Subtract 3y to both sides
-y = -10
~Divide -1 to both sides
y = 10

Help with G and H plz
Answer: For G the answer is x=30, for H x is 30
Step-by-step explanation:
G. The square means 90 degrees and the equation would be 90+3x=180. Subtract 90 from both sides would give you 3x=90 and divide it by 3 would give you x=30
H. The two lines means that both sides are congruent and so 75x2=150 150+x=180 subtract 150 from both sides would give you x=30

Ian bought a package of gummy bears that contains 4 cups. if he eats 2/3 cup everyday, how many days of candy does he have?
Answer:
6 days
Step-by-step explanation
2/3 cups x 3 days = 2 cups
2 cups x 2 cups = 4 cups
4 cups = 6 days
Answer:
6
Step-by-step explanation:
1) Get 4 and divide it by 2/3
2) To do this you put the inverse which is 4/1 x 3/2
3) Cross divide, then multiply.
4) (4/1 x 3/2) so 4/2 = 2 which is 2 (and whatever you do to one side, you have to do to the other side) so 2/2 is 1. Then 3/1 = 3 and 1/1 = 1 so it stays same. So now the equation becomes 2/1 x 3/1
5) This means the ones cancel out since in math ones don't have to be seen even though they are there.
6) 2 x 3 = 6
So you get 6
Sharon has a cake she wants to share with her friends. If she gave 2/5 to Sam and 1/5 to mary. How much does she have left for herself?
Answer:
2/5 of the cake
Step-by-step explanation:
First, find how much she gave away:
2/5 + 1/5
= 3/5
Then, to find how much she has left, subtract 3/5 from 1
1 - 3/5
= 2/5
So, she has 2/5 of the cake left for herself

What is 2.4(x-10)=8+1.2x-5
Answer:
x = 22.5
Step-by-step explanation:
Step 1: Write equation
2.4(x - 10) = 8 + 1.2x - 5
Step 2: Solve for x
Distribute 2.4: 2.4x - 24 = 8 + 1.2x - 5Combine like terms: 2.4x - 24 = 1.2x + 3Subtract 1.2x on both sides: 1.2x - 24 = 3Add 24 to both sides: 1.2x = 27Divide both sides by 1.2: x = 22.5Step 3: Check
Plug in x to verify it's a solution.
2.4(22.5 - 10) = 8 + 1.2(22.5) - 5
2.4(12.5) = 8 + 27 - 5
30 = 8 + 22
30 = 30
Answer:
x=22.5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2.4(x−10)=8+1.2x−5
(2.4)(x)+(2.4)(−10)=8+1.2x+−5(Distribute)
2.4x+−24=8+1.2x+−5
2.4x−24=(1.2x)+(8+−5)(Combine Like Terms)
2.4x−24=1.2x+3
2.4x−24=1.2x+3
Step 2: Subtract 1.2x from both sides.
2.4x−24−1.2x=1.2x+3−1.2x
1.2x−24=3
Step 3: Add 24 to both sides.
1.2x−24+24=3+24
1.2x=27
Step 4: Divide both sides by 1.2.
1.2x

Pls help!
Answer:
1. m∠1 = 45°
2. m∠1 = 129°
3. m∠1 = 37°
4. m∠1 = 88°
m∠2 = 42°
m∠3 = 113°
5. m∠1 = 62°
m∠2 = 45°
m∠3 = 24°
6. m∠1 = 128°
m∠2 = 52°
m∠3 = 47°
m∠4 = 133°
7. m∠1 = 41°
m∠2 = 85°
m∠3 = 95°
m∠4 = 85°
m∠5 = 36°
m∠6 = 50°
m∠7 = 107°
8. x = 9°
10. x = 5°
11. x = 7°
Step-by-step explanation:
1. m∠1 = 180° - (76° + 59°) = 45°
m∠1 = 45°
2. m∠1 = 62° + 67° = 129°
m∠1 = 129°
3. m∠1 = 152° - 115° = 37°
m∠1 = 37°
4. m∠2 = 42° (Alternate angles)
m∠1 = 180° - (50° + m∠2) = 180° - (50° + 42°) = 88°
m∠1 = 88°
m∠3 = 180° - (25° + 42°) = 113°
m∠3 = 113°
5. m∠3 = 73° - 49° = 24°
m∠3 = 24°
m∠2 = 118° - 73° = 45°
m∠2 = 45°
m∠1 = 180° - (73° + 45°) = 62°
m∠1 = 62°
6. m∠2 = 52° (Alternate interior angles)
m∠1 = 180° - 52° = 128° (The sum of angles on a straight line)
m∠1 = 128°
m∠3 = 47° (Alternate interior angles)
m∠4 = 180° - 47° = 133° (The sum of angles on a straight line)
m∠4 = 133°
7. m∠3 = 95° (Vertically opposite angles)
m∠2 = m∠4 (Vertically opposite angles)
m∠3 + 95° + m∠2 + m∠4 = 360° (The sum of angles at a point)
2 × 95° + 2 × m∠2 = 360°
m∠2 = (360° - 2 × 95°)/2 = 85°
m∠2 = 85° = m∠4
m∠2 = 85°
m∠4 = 85°
m∠1 = 360° - (85° + 140° + 90°) = 41°
m∠1 = 41°
m∠5 = 180° - 144° = 36°
m∠5 = 36°
m∠6 = 180° - (m∠5 + m∠3) = 180° - (36 + 95°) = 50°
m∠6 = 50°
m∠7 = 360° - (m∠4 - 38° - (180° - m∠6)) = 360° - (85° - 38° - (180° - 50°)) = 107°
m∠7 = 107° (Sum of angles in a quadrilateral)
8. (10·x - 11)° + (3·x - 2)° + (3·x + 1)° = 180°
Using an online application, we have;
(6·x - 12)° = 180°
x = (180 + 12)°/6 = 32°
x = 32°
9. (3·x - 5)° + (7·x + 5)° + 90° = 180°
Using an online application, we have;
10·x = 180° - 90° = 90°
x = 90°/10 = 9°
x = 9°
10. 151° = (11·x - 1)° + (20·x - 3)°
151° = 31·x - 4°
31·x = 151° + 4° = 155°
x = 155°/31 = 5°
x = 5°
11. (14·x - 13)° = (4·x + 13)° + (6·x + 2)°
(14·x - 13)° = (10·x + 15)°
(14·x - 10·x)° = (13 + 15)° = 28°
4·x = 28°
x = 28°/4 = 7°
