Answer:
- 4 7/30Step-by-step explanation:
-3 2/5 - 5/6 =- 17/5 - 5/6 = ⇒ converting the mixed fraction to standard- 17*6/5*6 - 5*5/6*5 = ⇒ bringing fractions to common denominator- 102/30 - 25/30 = - (102 + 25)/30 =- 127/30 = ⇒ answer as standard fraction- 4 7/30 ⇒ converting to mixed fractionAnswer:
- 4 ⁷/₃₀Step-by-step explanation:
= -3 2/5 - 5/6
= - 17/5 - 5/6 ---- LCM of 5 & 6 is 30
= _ 17 * 6 _ 5 * 5
5 * 6 6 * 5
= _ 102 - 25

Find the value of x so that the function has the given value.
j (x) = -4/5x + 7; j (x) = -5
Answer:
x = 15
Step-by-step explanation:
Step 1: Define
j(x) = -4/5x + 7
j(x) = -5
Step 2: Substitute and Evaluate
-5 = -4/5x + 7
-12 = -4/5x
x = 15

state what additional information is required in order to know that the triangles are congruent for the reason given.
Answer:
To me, it looks like it should already be eligible for SAS.
Step-by-step explanation:
SAS stands for Side, Angle, Side (what items have to be congruent for this method to work.)
As we look at the picture, there are two sides equal, and an angle between them.
So, it looks like SAS is already viable to use, without having to add more information! (at least from what I can say.)

Clay went for a run to prepare for a long distance race co ran 6 miles directly north and then 8 miles directly west. From there, he ran the diagonal distance back to his house. How many total miles did Clay run?
Answer:
24 miles
Step-by-step explanation:
so he went 6 miles, then 8 miles, then diagonally home.
which means he ran in a triangle.
Use the Pythagorean theory.
6*6=36
8*8=64
36+64=100
what square root = to 100?
10
so the questions is total moles did clay run.
6+8+10=24 miles
Santa Claus has been experiencing some recent back pain and is unable to carry large bags of toys over his shoulders. As a result he uses redex to deliver many of his gifts this year. Fedex charges a flat rate of $2.50 plus $0.85 per pound. If the cost of sending gifts to the Jones is $28.85, how much did their gifts weigh?
Answer: 31 pounds
Step-by-step explanation:
From the question, we are informed that Fedex charges a flat rate of $2.50 plus $0.85 per pound and that the total cost of sending gifts to the Jones is $28.85. This can be mathematically expressed as:
2.50 + 0.85p = 28.85
where p = weight of the gift
So we have to solve the equation
2.50 + 0.85p = 28.85
0.85p = 28.85 - 2.50
0.85p = 26.35
p = 26.35/0.85
p = 31
Therefore the weight of the gift is 31 pounds
Which situation can be modeled by the inequality m > 225? A. The community theater's auditorium can seat at most 225 people. B. The number of people who attended the mathematics conference was more than 225. C.The students need to raise at least $225 in order to pay for the bus ride to go on a field trip. D. The distance Deshawn must travel from his house to reach the Gulf Coast is less than 225 miles.
Answer:
B. The number of people who attended the mathematics conference was more than 225.Step-by-step explanation:
Given the inequality m > 225, the inequality means that m is greater than 225. Since the inequality sign does not include equal to sign, then the value of m cannot be less than and equal to 225. The situation that best fits the expression based on the explanation above is "The number of people who attended the mathematics conference was more than 225"
Emphasis should be on 'WAS MORE THAN' according to the statement. The greater sign means that the number of people will always be greater than or more than 225 representing the variable m as the number of people.

solve for x in geometry
Answer:
x = 3
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
28x - 2 is an exterior angle of the triangle, thus
28x - 2 = 15x - 3 + 40 = 15x + 37 ( subtract 15x from both sides )
13x - 2 = 37 ( add 2 to both sides )
13x = 39 ( divide both sides by 13 )
x = 3
Solve for x.

all multiples of 5 end with 5 true or false
Answer:
FALSE
Step-by-step explanation:
Multiples of 5 end with 5 or 0.
Answer:
False
Step-by-step explanation:
Think of the first couple of multiples for 5, 5, 10, 15, 20 and so on. As you can see 10 and 20 are multiples of 5 but do not end with a 5.
Elena wants to prove that the measures of the 3 angles in a triangle always
sum to 180 degrees. She starts by using rigid motions to rotate triangle ABC
180° around 2 midpoints. Explain how Elena labeled her diagram and finish
her proof.

С
В
B
My best explanation to this question is:
Elena has summed the total of all three angles in the straight angle to get 180°; <DAB, <BAC , and <CAE. But this does not mean a total of three angles will ALWAYS equal 180°. If one angle is greater than the other two, then there is a possible chance the angle will not be 180°. If the angles are scalene, then there is a greater chance the angle may not be 180°.
This may be wrong, so you don’t have to come up with my response exactly, just modify it to what you need. Wish you luck.
The measures of the 3 angles in a triangle always sum to 180 degrees.
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
We have to determine the prove that the measures of the 3 angles in a triangle always sum to 180 degrees.
We have been given that angles as
∠ DAB, ∠ BAC, and ∠ CAE.
Each 180-degree rotation takes line BC to a parallel line. So line DA is parallel to BC and line AE is also parallel to BC.
There is only one line parallel to BC that goes through point A, so lines DA and AE are the same lines.
Since line DE is parallel to line BC,
∵ alternate interior angles are congruent.
This represents that angle BAD also measures b" and angle CAE also measures c'. D
Since DE is a line, the 3 angle measures at point A would sum to 180 degrees.
So a + b + c = 180.
The fact that this explanation is dependent on the triangle we started with indicates that any triangle's sum of its three angles is always 180 degrees.
Therefore, the measures of the 3 angles in a triangle always sum to 180 degrees.
