- 4x < 68
A. Solve by adding 4 to each side.
B. The solution is x>-17.
a or b will mark as brainliest
(ignore the last thing)
Answer:
B.x>-17
Step-by-step explanation:
1. Divide both sides by -4:
-4x/-4<68/-4
2.< will change to > since you are dividing by negative
3.your final answer will be x>-17

Determine whether the triangles are congruent. Explain your reasoning .
SAS (Side, Angle, Side) or ASA (Angle, Side, Angle)
Answer:
Yes, SAS Theorem
Step-by-step explanation:
The triangles are congruent because of SAS Theorem that states that if two triangles have two sides and the angel in between them congruent the triangles are congruent.
JK≅NM (Side) because the sides have the same measure 74in. they are ≅
∡J≅∡M (Angle) because the angles have same measure 37° they are ≅
JL≅PM (Side) because the sides have the same measures 46in. they are ≅
Find the value of cos W rounded to the nearest hundredth, if necessary,
U
30
W
V
14
Answer:
cos W = 7/15
Step-by-step explanation:
Mathematically the cosine of an angle is the ratio of the adjacent to the hypotenuse side
From the diagram given, 14 is adjacent to vertex w and 30 faces the right angle which makes it the hypotenuse
So, we have it that;
cos W = 14/30
cos W = 7/15

4 1/2 ounces per 3/4 miles
_____ ounces per 1 mile
Answer: 6
Step-by-step explanation:
To get 3/4 miles to 1 mile we must take the reciprocal of the number and multiply it.
[tex]\frac{3}{4}[/tex]×[tex]\frac{4}{3} =1[/tex]
We need to multiply the 4 1/2 ounces by 4/3 too
[tex]4\frac{1}{2}[/tex]×[tex]\frac{4}{3} =6[/tex]
4 1/2 ounces per 3/4 miles
6 ounces per 1 mile
Answer:
6 ouncesStep-by-step explanation:
Let the unknown number be x
[tex]4 \frac{1}{2} \: \: ounces = \frac{3}{4} \: \: miles \\ x = 1 \: \: mile[/tex]
Now simply use cross multiplication to solve it
[tex]4 \frac{1}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} \times 1 = \frac{3}{4} x \\ \frac{9}{2} = \frac{3x}{4} \\ [/tex]
Now make x as the Subject
[tex] \frac{9}{2} = \frac{3x}{4} \\ \frac{9 \times 4}{2 \times 3} = x \\ \frac{36}{6} = x \\ 6 = x[/tex]
So the answer is

I need help plzzzzzz like ASAP
Step-by-step explanation:
Angles in a triangle add up to 180° and angles on a straight line add up to 180° with this information we can solve this problem.
180° - 95° = 85°
Now you have two of the angles, which means all you have to do to find the x is add your two angles up and take them away from 180°.
85° + 60° = 145°
180° - 145° = 35°

Step-by-step explanation:
Which correlation coefficient would indicate a strong negative correlation? a. r = -0.93 b. r = -0.23 c. r = 0.75 d. r = 1.0
Answer:
A. r = -0.93
Step-by-step explanation:
First, if there is a negative correlation, the correlation coefficient will be negative.
This eliminates answer choices C and D, which are positive.
If there is a strong correlation, the correlation coefficient will be closer to 1, or -1 (since the correlation is negative).
Since -0.93 is closer than -0.23 to 1, it has a stronger correlation.
So, the correct answer is A. r = -0.93

Can someone please give me the answer to this
Answer:
The answer is (4, -6)
Step-by-step explanation:
Point C starts at (2, -5). The triangle moves 2 units right, so 2 + 2 = 4 and 1 unit down, so -5 - 1 = -6

Answer and Step-by-step explanation:
The slope would be positive 1. (Third answer choice).
This is because, using the Rise over Run method of finding slope, we go 1 unit up and 1 unit to the right, showing that it is going in the positive direction (up and right) and has a slope of 1.

Robert is selling his bulldozer at a heavy equipment auction. The auction company receives a commission of 5% of the selling price. If Robert owes $124,850 on the bulldozer, then what must the bulldozer sell for in order for him to be able to pay it off?
Answer:
$131422
Step-by-step explanation:
Given :
Amount owed = $124,850
Commison on sale = 5%
Let :
Sale price of bulldozer = x
Sale price = amount owed + 5% of sale price
x = 124850 + 0.05*x
x = 124850 + 0.05x
x - 0.05x = 124850
0.95x = 124850
x = 124850 / 0.95
x = 131421.05263
To the nearest dollar = $131422

The proper way to express the above inequality is 6x4(2x-1) is x2.
What is inequality?A mathematical statement that has two mathematical expressions on each side of the inequality sign is called an inequality. The indicators for inequality are,, >, or.
6x4(2x-1) is the given inequality.
So, 6x≥8x-4
6x off of both sides gives us
6x-6x≥8x-4-6x
0≥8x-6x-4
0≥2x-4
4 added on both sides give us
0+4≥2x-4+4
4≥2x
By dividing both sides by half, we obtain
(1/2)×4≥(1/2)×2x
2≥x
x≤2
Therefore, x≤2 is the correct representation.

HELP!!! How did Mohomed Ghandi get so skinny? I'm doing a biography on him and need an answer ASAP!!!
Answer:
In 1911, he went on a no salt diet, (which he eased up after some time and convincing from doctors) which is bad for you since you need salt to survive. He also gave up meat and became a vegetarian, though he did attempt veganism, but faced many health problems, so he discontinued it. The last reason was because he fasted. A lot. And for long periods of time.

Answer:
D (last answer)
Step-by-step explanation:
solve and simply
a=8 and b=2.25 but what is k
Answer:
a = 8, b = 2.25, k = 27Step-by-step explanation:
y = abˣPoints on the graph:
(0, 8), (1, 18), (1.5, k)Substitute coordinates into equation and solve for and and b:
8 = ab⁰ ⇒ 8 = a*1 ⇒ a = 818 = 8b ⇒ b = 18/8 ⇒ b = 2.25Find k:
k = 8*[tex]2.25^{1.5}[/tex] = 27Answer:
a=8
b=9/4
k = 27
Step-by-step explanation:
y = ab^x
We know that a is the initial value or when x = 0
We know the point (0,8) so a = 8
y = 8 b^x
Using the point (1,18) for x and y we can find b
18 = 8 * b^1
18/8 = b
9/4 = b
Now
y = 8 * ( 9/4) ^ x
Letting x = 1.5
k = 8 *(9/4)^1.5
k = 27
Find the measure of angle A (*find the value of x first!):
Answer:
A = 90º
x = 22.5º
Step-by-step explanation:
So, because sides AC and AB are equal, angles C and B are equal- that means that angle B is also 2x. So for our whole triangle, 2x + 2x + 4x = 180º (all triangles internal angles add up to 180º).
From there, we can simply solve for x:
8x = 180º
x = 22.5
And now we can solve for angle A, which is 4xº. When we substitute it is:
4 (22.5)
A = 90º
