Because it is an isosceles triangle, the 2 sides that are given will be equal to each other.
15=4x+3
(subtract 3 on both sides)
12=4x
(divide by 4 on both sides)
x=3
Hope it helps!
Answer:
x = 3.
Step-by-step explanation:
1. 4x + 3 = 15
2. Subtract 3 from both sides.
3. Divide by 4 from both sides.

the sum of three numbers is 182, the second is 6 times bigger than the first and the third is 14 times bigger than the second number, what are those numbers?
Answer:
The numbers are [tex]2,12,168[/tex]
Step-by-step explanation:
Let the numbers be [tex]a,b,c[/tex]
We have
The sum of three numbers is [tex]182[/tex]
[tex]a+b+c=182-----eqn1[/tex]
The second is [tex]6[/tex] times bigger than the first
[tex]b=6a-----eqn2[/tex]
The third is [tex]14[/tex] times bigger than the second number
[tex]c=14b-------eqn3[/tex]
Substituting in eqn 3
[tex]c=14\times 6a=84a ----eqn4[/tex]
Substituting in eqn 1
[tex]a+6a+84a=182\\\\91a=182\\\\a=2[/tex]
Substituting in eqn 2
[tex]b=6\times2=12[/tex]
Substituting in eqn 3
[tex]c=14\times12=168[/tex]
The numbers are [tex]2,12,168[/tex]
The first number is a , the second number is b , the third number is c
( 0 < a < b < c )
The sum of three numbers is 182
⇒ a + b + c = 182 (1)
The second is 6 times bigger than the first
⇒ b = 6a (2)
The third is 14 times bigger than the second number
⇒ c = 14b = 14.6a = 84a (3)
(1),(2),(3): ⇒ a + 6a + 84a = 182
⇒ 91a = 182
⇒ a = 2
⇒ b = 6a = 6.2 = 12
⇒ c = 14b = 14.12 = 168
Those numbers are 2 , 12 , 168

Answer:
[tex]x=6; y=-6[/tex]
Step-by-step explanation:
Unless you're required to use any particular method, let's add the first to twice the second to eliminate x:
[tex]6x+y-6x-15y=30+54 \rightarrow -14y=54 \rightarrow y=-6[/tex]

Kay's mother taught her how to make handmade ornaments to sell at a craft fair. Kay rented a table at
the fair for $30 and set up her work station. Each ornament that she makes costs approximately $2.50
for materials. She sells each ornament for $6.00.
If x represents the number of ornaments sold at the craft fair, which of the following expressions
would represent Kay's profit? (Circle all choices that apply.)
A. -30 + 6x - 2.50x
B. 6x - 30 -2.50x
C. 6x - 30
D. 4.50x - 30
E. 3.50x - 30
Answer without link please
Answer: B
Step-by-step explanation: 6x represents the positive because it represents the amount being made from each ornament. The -30 represents the one-time cost of the table. And the -2.50x represents the cost of each ornament.

EXPLAIN HOW YOU GOT IT
Answer:
y = x - 70
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 70) and (x₂, y₂ ) = (70, 0) ← 2 points on the line
m = [tex]\frac{0-(-70)}{70-0}[/tex] = [tex]\frac{0+70}{70}[/tex] = [tex]\frac{70}{70}[/tex] = 1
The line crosses the y- axis at (0, - 70 ) ⇒ c = - 70
y = x - 70 ← equation of line

Answer:
Tan (X) = 72/65. = 1.1
Step-by-step explanation:
tan x = (opposite side) / (adjacent side)
From angle X the adjancent is the closest leg which has the value of 65 and the opposite is the furthest leg with a value of 72. (the line that is connecting the legs which is the biggest line is the hypotenuse and has a value of 97). You will not need the hypotenuse I just gave you extra information for future purposes.
so, since tan x = (opposite side) / (adjacent side):
Tan (X) = 72/65.

Step-by-step explanation:
You have a box of fruit flies that are left untouched. The fruit fly population doubles every 3 hours. Would this equation be linear or exponential?
Group of answer choices
Exponential
Linear
Answer:
B Exponential
Step-by-step explanation:
Hope this helps
The equation for the fruit fly population doubling every 3 hours would be exponential.
Exponential growth occurs when a quantity increases at a fixed percentage over fixed intervals of time. In this case, the population of fruit flies doubles, which means it is increasing by 100% every 3 hours.
The general form of an exponential growth function is given by: y = a * b^x
Where:
- y is the final quantity or population size after x intervals of time.
- a is the initial quantity or population size at the beginning (in this case, the initial number of fruit flies).
- b is the growth factor (in this case, b = 2 since the population doubles every 3 hours).
- x is the number of intervals of time (in this case, the number of 3-hour periods).
In the context of the fruit fly population, the equation would be in the form of y = a * 2^x, where the population of fruit flies increases exponentially as time passes. This is why the equation is exponential.

Step-by-step explanation:
The solution is 1.804 x 10⁷
The product of the two numbers is given by the equation A = 1.804 x 10⁷
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the product of two numbers be A
Now , the equation will be
Let the first number be P = 41
Let the second number be Q = 4.4 x 10⁵
The value of Q = 4.4 x 100000
The value of Q = 440000
The product of two numbers A = P x Q
Substituting the values in the equation , we get
The product of two numbers A = 41 x 440000
On simplifying the equation , we get
The product of two numbers A = 1,80,40,000
So , the value of A = 1.804 x 10⁷
Hence , the product of numbers is A = 1.804 x 10⁷
