help! I only have a certain amount of time.... easy points! The sum of 3 times a number and 4 is 13. Find the number.
Answer:
The number is 3
Step-by-step explanation:
Ok, first thing's first: we need to make the words into an actual equation.
since it just says a number I'll use x
3 times x + 4 = 13
3x +4 =13
Now that we have our equation, we can solve for x
3x + 4 = 13
-4 -4
3x = 9
I subtracted 4 on both sides to get rid of the 4 and move it to the other side of the equation, so we can try to get x by itself.
3x =9
/3 /3
x = 3
I divided both sides by 3 to get rid of the 3 that's being multiplied by x
Now we have our number : x = 3

Step-by-step explanation:
Given that:
Height of person = 2metres
Length of person's shadow = 6 meters
Height of flagpole =?
Length of flagpole shadow = 24 meters
Height of person = length of person's shadow

Answer:
acute scalene triangle
Step-by-step explanation:
The largest angle is acute, and all sides are different lengths. The triangle is an acute scalene triangle.
____
The magnitudes of the coordinate differences are ...
WX = (7, 5), XY = (2, 7), WY = (9, 2)
The two sides that are closest in length are ...
WX = √(49+25) = √74
WY = √(81 +4) = √85
Obviously, these are different lengths.
You can get a clue by comparing the numbers whose squares you are adding:
7^2 +5^2 > 7^2 +2^2 . . . . . WX > XY
9^2 +2^2 > 7^2 +2^2 . . . . WY > XY
so, the only question is relation between WX and WY. We note that the length of WX is less than one of the coordinate differences of WY, so we know WY is the longest. (√74 < 9)
We can tell from the graph that angle X (opposite longest side WY) is an acute angle, so the triangle is acute.

The two triangles are symmetrically the same the only difference is they are opposite Intersecting at C.
Angle DCE and BCA intersect from the triangles which both form a similar angle let's assume are 60 degrees.
Therefore, Angle ACE and BCD are 120 degrees.
Therefore all sides from both triangles correspond to be both equal, for example, BA = ED, AC = DC, BC = EC
C is the midpoint of AD and BE therefore AC = CD and BC = CE.
The angles too are equally corresponding such as,
Angle ABC = DEC , CAB = CDE and BCA = ECD

Jim's science class is making slime from cornstarch and glue. Jim is helping pass out materials. He gives each student 80 grams of cornstarch from a 2-kilogram bucket. If Jim's class has a total of 21 students, how many grams of cornstarch will he have left?
The total amount of corn starch left is 320 grams.
How to find the grams of corn starch left?He gives each student 80 grams of corn starch from a 2-kilogram bucket.
Each students collected 80 grams of corn starch.
Therefore,
1 student = 80 grams of corn starch
His class has a total of 21 students.
Therefore,
total mass of corn starch distributed = 21 × 80
total mass of corn starch distributed = 1680 grams
The corn starch from the bucket = 2 kg
1kg = 1000 g
2kg = 2000g
Hence,
The corn starch from the bucket = 2000 grams
Finally,
amount in grams of corn starch left = 2000 - 1680
amount in grams of corn starch left = 320 grams.

in a right triangle, the side c opposite the right angle is called the hypotenuse, and the other two sides a and b are called legs. the pythagorean theorem states that in any right triangle, the lengths of the three sides are related by the equation . use the pythagorean theorem to answer the following question. determine the length of the hypotenuse in a right triangle with legs 5 inches and 12 inches. a. approximately 13.38 inches b. 13 inches c. 169 inches d. 17 inches
The length of the hypotenuse is 13.
A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
According to the question ,
Given that , legs is 5 inches and 12 inches
how to find hypotenuse :
we know , c^{2} = a^{2} + b^{2}
⇒ c^{2}= 5^{2} + 12^{2}
⇒ c^{2} = 25 + 144
⇒ c = \sqrt{169}
⇒ c = 13
The length of the hypotenuse is 13.
Correct option is (b) 13 inches .

2(9n-1)+7(n+6)=-60
what is this answer
Answer:
n=-4
Step-by-step explanation:
2 (9n-1)+7(n+6)= -60
18n-2 +7n + 42 = -60
25n + 40 = -60
25n = -100
n = -4
Answer:
n = - 4
Step-by-step explanation:
2 ( 9n - 1 ) + 7 ( n + 6 ) = - 60
Solve the brackets.
18n - 2 + 7n + 42 = - 60
Combine like terms.
25n + 40 = - 60
Subtract 40 from both sides.
25n = - 60 - 40
25n = - 100
Subtract 25 from both sides.
n = -4

If m2 = 9x + 7 and m3 = 5x + 5, what is m1?
Answer:
B
Step-by-step explanation:
∠ 2 and ∠ 3 are a linear pair and sum to 180°
∠ 2 + ∠ 3 = 180 , that is
9x + 7 + 5x + 5 = 180
14x + 12 = 180 ( subtract 12 from both sides )
14x = 168 ( divide both sides by 14 )
x = 12
Then
∠ 3 = 5x + 5 = 5(12) + 5 = 60 + 5 = 65°
∠ 3 and ∠ 1 are vertically opposite angles and are congruent , so
∠ 1 = 65°
the adams family and the green family each used their sprinklers last summer. the water output rate for the adams family's sprinkler was per hour. the water output rate for the green family's sprinkler was per hour. the families used their sprinklers for a combined total of hours, resulting in a total water output of . how long was each sprinkler used?
The duration of the sprinkler used by each families are-
Adams family: 25 hoursGreen family: 30 hoursWhat is linear equation in two variables?Linear equations in two variables are equations with one, none, and infinitely many solutions where each of the two variables has the highest exponent order of 1.
A two-variable linear equation has the standard form ax + by + c = 0, where x and y are the variables. The solutions could also be composed in pairs, such as (x, y).Now, as per the given question;
Let the total time taken by Green family is 'x'.
Let the total time taken by Adams family is 'y'
The total time for which the sprinkler are used is 55 hours.
Thus, x + y = 55 (equation 1)
The water output rate for the Green family's sprinkler was 30 L per hour.
The water output rate for the Adams family's sprinkler was 20 L per hour.
The total output of the water is 1400 L.
Then,
30x + 20y = 1400 (equation 2)
Substitute the value of x from equation 1 in equation 2.
30(55 - y) + 20y = 1400
Dividing whole equation by 10.
3(55 - y) + 2y = 140
Solving the equation.
165 - 3y + 2y = 140
y = 165 - 140
y = 25 hours. (Time for which Adams family used the sprinklers)
Put value of y in equation 1 to find x.
x = 55 - y
x = 55 - 25
x = 30 hours. (Time for which Green family used the sprinklers)
Therefore, the time for which both of the families used the sprinklers is estimated.

Answer:
250x + 525y ≤ 7800
no, 15 refrigerators and 8 pianos will not fit on the truck
Step-by-step explanation:
we know that x is the refrigerators and each one is 250 lbs
this can be written as 250x
we know that y is the pianos and each one is 525 lbs
this can be written as 525y
we also know that "no more than" is the same that as less than equal to
so this can be written as ≤
we can also say that the refrigerators and pianos has to be ≤ 7800
so now we have: 250x + 525y ≤ 7800
plug in 15 to x and 8 to y
250(15) + 525(8) ≤ 7800
3750 + 4200 ≤ 7800
7950 ≤ 7800
this statement is not true so no, 15 refrigerators and 8 pianos will not fit on the truck
