Answer:
A= -8
Step-by-step explanation:
Subtract 5a from both sides.
Combine 4a and −5a to get −a.
Add 7 to both sides.
Finally, Multiply both sides by −1.
Pls mark brainliest.
Answer:
a = -8
Step-by-step explanation:
4a - 7 = 5a + 1
subtract 1 from both sides of the equation
4a - 7 - 1 = 5a + 1 - 1
4a - 7 - 1 = 5a
4a - 8 = 5a
subtract 4a from both sides of the equation
4a - 4a - 8 = 5a - 4a
-8 = 5a - 4a
-8 = 1a
-8 = a
The rope was coiled into circular
loops about 30 inches in diameter.
To the nearest foot, each loop of rope
was about how many feet long?
Answer:
94.25 or 94
Step-by-step explanation:
I think this question is asking for the circumference .
The length of each loop of rope is about 8 feet when the rope was coiled into circular loops of about 30 inches in diameter.
To find the length of the rope in each circular loop, we need to calculate the circumference of the circle. The circumference is the distance around the circle and can be calculated using the formula:
Circumference = π * Diameter
Diameter = 30 inches
To find the length in feet, we need to convert the inches to feet. Since there are 12 inches in a foot, we divide the diameter by 12:
Diameter in feet = 30 inches / 12 inches/foot = 2.5 feet
Now, we can calculate the circumference:
Circumference = π * Diameter
Circumference = π * 2.5 feet
To find the approximate length in feet, we need to use an approximation for π. Let's assume π ≈ 3.14:
Circumference ≈ 3.14 * 2.5 feet
Circumference ≈ 7.85 feet
To the nearest foot, the length of each loop of rope is about 8 feet.

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.
On Monday at 1pm, when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
What was the net change in the elevation of the ocean’s surface from 1 p.m. to 7 p.m.?
Answer:
-4.6 ft
Step-by-step explanation:
The question is asking for the net change in the ocean's surface elevation, so we can ignore the parts of the question that mention his own elevation at the time of the measuring. We can see at 1, the elevation was 2.2, and at 7, the elevation was -2.4. The net change is the whole change over the period of time, so we just need to find the difference between the two. Adding them together gives you the distance from each elevation the sea's surface was, which is -4.6 ft as the elevation decreased

The nth term of a sequence is 2n2 − 1 The nth term of a different sequence is 40 − n2 Show that there is only one number that is in both of these sequences.
Answer:
Step-by-step explanation:
nth term of a sequence = 2n² - 1
Therefore, terms of the sequence will be,
1, 7, 17, 31, 49, ........... n terms
nth term of a different sequence = 40 - n²
Therefore, terms of the sequence will be,
39, 36, 31, 24, 15, 4, -9, -24 .......... n terms
Since, there is no negative number in the first sequence,
Therefore, out of 6 positive terms of second sequence only one number (31) is common in both the sequences.

the answer itself is m< 4=87
Step-by-step explanation:
Answer:
The answer is 87°
Step-by-step explanation:
A quadrilateral has an interior angle sum of 360°.
Given that three of the four angles in a quadrilateral are 89°, 80°, and 104°, we can create the following equation where x is the missing angle:
89° + 80° + 104° + x° = 360°.
All you have to do is add all the measures up and subtract from 360°.
89° + 80° + 104° + x° = 360° →
273° + x° = 360° →
x° = 87°.
Also, for any polygon, the interior angle sum is (n – 2) × 180°, where n is the number of sides.
A quadrilateral is a polygon with four sides so it's interior angle sum must be
(4 – 2) × 180° = 2 × 180° = 360°.

If a game player scored a 27 on the first game and a 39 on the second game, which number statement can be used to find what the player needs to score on the third game (S) to have a
mean (average) score of 36?
A. 27 +39+ S3 = 36
B. 363 = 27 +39 + S
C. (36 + 3) + S +27 +39
D. (27 +39 + S) + 3 = 36
Answer:D
Step-by-step explanation:
Answer: none of them are right...
Step-by-step explanation:
(27 + 39 + S)/3 = 36
27 + 39 + S = 36(3)
27 + 39 + S = 108
S = 108 - 39 - 27
S = 42

Mark often buys lunch at the deli next to his work. Lunch at the deli costs $7.50. Mark sets aside $150 for lunches at the deli at the beginning of the month. Which equation describes how much money, y, Mark has after eating lunch at the deli x times during the month?
Answer:
y = 150 - 7.50x
Step-by-step explanation:
Given that:
Cost per lunch = 7.50
Amoint budgeted for lunch = $150
The equation which models the amount of money, y Mark has after eating x times at the Deli
Amount left = Amount budgeted for lunch - (cost per lunch * number of lunch eaten)
y = $150 - ($7.50 * x)
y = 150 - 7.50x

f(3) = 3x² +b For the function, f, defined above, f(4) = 49. What is the value of b?
Answer: 5.4~
Step-by-step explanation:
For the problem F(3) = 3x^2 +b, you have to first figure out what F(3) is and in this case it is 49, so now you have part of the question solved. Then you start working on the other side of the equation 3x^2 +b = 49, we don't know what x is so lets figure it out, by that you need to do 3x^2, the equals 9. So, so far we have the equation 49 = 9x +b. Now we need to get rid of the x on the 9, having a variable is considered multiplying so you need to divide 9 by 9, but remember what you do to one side you have to do to the other, so now you have to divide 49 by 9 and you get 5.444444444. Now the equation is b=5.4~ meaning that b is around 5.4, I hope this helps.

Solve the equation below for x in terms of a 4(ax+3)-3ax=25+3a
Answer:
x = (13 + 3a) / a
Step-by-step explanation:
Given equation:
4(ax+3) - 3ax = 25 + 3a
Open parenthesis
4ax + 12 - 3ax = 25 + 3a
Collect like terms
4ax - 3ax = 25 + 3a - 12
Simplify
ax = 13 + 3a
x = (13 + 3a) / a
4(ax+3) - 3ax = 25 + 3a is equivalent to x = (13 + 3a) / a
