Solve –2k + 12 < 30 for k.
Answer:
k<-9
Step-by-step explanation:
First you want to isolate the variable, or k in this case. So you will subtract 12 on both sides which will leave you with -2k<18. Then you will divide both sides by -2. Which turns into k>-9. But since you divided by a negative, the sign changes, so the answer would be k<-9.

Step-by-step explanation:
two of the triangles' corresponding angles are the same even if the side lebgths are not, making these two similar
By AA similarity triangle ABC and triangle LMN are similar. Therefore, option A is the correct answer.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
In the given triangle ABC, ∠A=50° and ∠B=75°.
In the given triangle LMN, ∠L=50° and ∠M=75°
From the given triangles,
∠A=∠L=50°
∠B=∠M=75°
By AA similarity triangle ABC and triangle LMN are similar.
Therefore, option A is the correct answer.

Pls pls pls help!! Will mark correct answer brainliest
Answer:
its 3.5
Step-by-step explanation:
since we need to replace x with 6 the equation is now 3(6) + 8y = -10.
next i would multiply 3&6 to 18 then subtract 8y to the other side like this
18 + 8y = -10
- 8y -8y
18= -10 -8y
then i would add -10 to 18 on that side
18= -10 -8y
+10 +10
28 = 8y
then i divided

The area of the triangle below is 3/4
square feet. What is the length of the base? Express your answer as a fraction in simplest form.
Answer:
base = 5 ft.
4
Step-by-step explanation:
area of a triangle = 1/2 * base * height
where area = 3/4 ft²
height = 6/5 ft.
plugin values into the formula:
3 = 1 x base x 6
4 2 5
base = 3 x 2 x 5
4 x 6
base = 30 / 6
24 / 6
base = 5
4
We need to find the base of the triangle in its simplest form
The base of the triangle in it's simplest form is 5/4 ft
Area of a triangle
[tex] = \frac{1}{2} \times base \: \times height[/tex]
Area of the triangle = 3/4 square feet
Height of the triangle = 6/5 ft
let
b = base of the triangle
Area of a triangle
[tex] = \frac{1}{2} \times base \: \times height[/tex]
3/4 = 1/2 × b × 6/5
3/4 = 6/10 × b
divide both sides by 6/10
b = 3/4 ÷ 6/10
= 3/4 × 10/6
= 30/24
b = 5/4 ft
base of the triangle = 5/4 ft

A group of friends went to the movies. They shared 2 bags of popcorn equally. If each person got 2/3 of a bag of popcorn, how many people were in the group?
Answer:
There would have been three people in the group.
Step-by-step explanation:
This is because if you add 2/3 together until you get that amount, it will add up to having three people. If this sounds confusing, here is a visual thing to help.
2/3+2/3=4/3 which can also equal 1 1/3
1 1/3 + 2/3 =2
you added 2/3 together three times to get two, so three is the answer.

The value of x is 10 more than 5 times the value
of y. The sum of the two numbers is 4. Write,
two equations and graph to find the values of x
and y.
Step-by-step explanation:
x = 5y+10
y = y
The sum of the two numbers is 4
therefore,
5y+10+y = 4
6y+ 10 = 4
6y = 4 -10
6y = -6
y = -1
X = 5y+10
X = 5 ×(-1)+10
X = 5
hence, y is -1 and X is 5
Answer:
x=10+5y
4=x+y
Step-by-step explanation:
substitute
4=10+5y+y
4-10=6y
-6=6y
-1=y
x=5

y is directly proportional to x. When y = 24, ,x=8. Work out the value of y when x=2
Answer:
When x = 2, y = 6
Step-by-step explanation:
Constant of Proportionality: y = kx
(24) = k(8)
24 = 8k
k = 3
y = kx ===> y = 3x
When x = 2:
y = 3x
y = 3(2)
y = 6
