solve for x.
x/2.5<10
Answer:
x < 25
Step-by-step explanation:
x/2.5 < 10
you need to get x alone so you multiply both sides by 2.5 to get the 2.5 crossed out on one side
x < 2.5 times 10

Can someone help me please
There are two approaches to this question.
Approach 1:
We can compute the slope of a line by calculating its mean variation, the rise over run. Mathematicaly:
[tex]a=\frac{\Delta y}{\Delta x}[/tex]
The two points we have are [tex]P1 = (1,3)[/tex] and[tex]P2 = (4,3)[/tex]. Plugging the values into the expression we get
[tex]a=\frac{3-3}{4-1} \\a=0[/tex]
Therefore, the slope of the line is zero.
Approach 2:
The slope of the line is given by the angle [tex]\alpha[/tex] it makes with the X axis, in other words,
[tex]a = tan(\alpha)[/tex]
Note that the angle the line makes is exaclty zero. Therefore:
[tex]a= tan(0)\\a=0[/tex]
Again, we get that the slope of the line is zero.
In general, the slope of any horizontal line will always be zero.

Answer:
A) -6n-6
Step-by-step explanation:
g(h(n)) means you are plugging in the value of h(n) into g(n) for n:
Given:
[tex]g(n)=-2n+4\\h(n)=3n+5[/tex]
Therefore:
[tex]g(h(n))=-2(3n+5)+4\\g(h(n))=-6n-10+4\\g(h(n))=-6n-6\\[/tex]
This means your final answer is A) -6n-6

if 4/3 x 3/4 = 5k, then k = ?
Answer:
k= 1 /15 x^3
Step-by-step explanation:
4/3 x 3/4 = 5k
5k= 1 /3 x^3
k= 1 /15 x^3
The required value of k in the given equation (4/3) × (3/4) = 5k is 1/5.
To find the value of k in the equation (4/3) × (3/4) = 5k, we need to simplify the left side of the equation and solve for k.
Multiplying the fractions on the left side:
(4/3) × (3/4) = 12/12 = 1
Now we have the equation 1 = 5k. To solve for k, we need to isolate it on one side of the equation.
Dividing both sides of the equation by 5:
1/5 = k
Hence, the value of k in the given equation is 1/5.

The correct question is as follows:
If (4/3) × (3/4) = 5k, then find the value of k.

Rusty hiked 3 3/4 miles in the morning and 2 1/4 miles in the afternoon. How much
farther did he hike in the morning than the afternoon?
Answer:
1 [tex]\frac{1}{2}[/tex] miles
Step-by-step explanation:
Convert 3 [tex]\frac{3}{4}[/tex] and 2 [tex]\frac{1}{2}[/tex] into improper fractions
Subtract them like a regualr equation
[tex]\frac{15}{4}[/tex] - [tex]\frac{9}{4}[/tex] = [tex]\frac{6}{4}[/tex]
Convert [tex]\frac{6}{4}[/tex] into a mixed number to get 1 [tex]\frac{1}{2}[/tex]
1. Find x
2 find ab
3.Find bc
AC = 46
AB + BC = AC
(4x + 7) + (3x + 4) = 46
4x + 7 + 3x + 4 = 46
(4x + 3x) + (7 + 4) = 46
7x + 11 = 46
7x = 46 - 11
7x = 35
x = 35/7
x = 5
AB = 4x + 7
AB = 4(5) + 7
AB = 20 + 7
AB = 27
BC = 3x + 4
BC = 3(5) + 4
BC = 15 + 4
BC = 19

Given congruent triangles ΔABC ≅ΔDEF where AB = 11, BC = 5, and DE = 6x-7. Find the value of x.
Answer: Congruent angles are angles that have the same measure. ... y = 67 x = 180 – 67 = 113. 2. x = ______ y = ______. 3x – 5 = 127. +5 +5. 3x = 132 ... Find the measure of the angle and give the reason for knowing it. ... Solve for the unknown values: ... 2) AD. 3) AB. 4) BC. 24. In ΔABC, If CA ≅ CB and m∠A = 50, find the m∠B.
Answer:
x = 3
Step-by-step explanation:
Since the triangles are congruent then corresponding sides are congruent, that is
DE = AB , substitute values
6x - 7 = 11 ( add 7 to both sides )
6x = 18 ( divide both sides by 6 )
x = 3
