Answer:
x = 3/2
Step-by-step explanation:
Let's solve your equation step-by-step.
(3)(1)+2x=6
Step 1: Simplify both sides of the equation.
(3)(1)+2x=6
3+2x=6
2x+3=6
Step 2: Subtract 3 from both sides.
2x+3−3=6−3
2x=3
Step 3: Divide both sides by 2.
2x/2 3/2
x = 3/2

State A contains the largest state population of Native Americans. This population is three times the Native American
population of State B. If the total of these two populations is 376 thousand find the Native American population in
each of these two states.
The Native American population in state A and B is 282,000 and 94,000 respectively.
Here, we are given that State A's population of Native Americans is three times the Native American population of State B.
Let the Native American population in state B be x
Thus, the Native American population in state A will be 3x
Total Native American population in state A and B = 376,000
Thus, we can get the following equation-
x + 3x = 376,000
4x = 376,000
x = 376,000/ 4
x = 94,000
⇒ 3x = 3 × 94,000
3x = 282,000
Thus, the Native American population in state A and B is 282,000 and 94,000 respectively.

f(x) = -4x + 7
g(x) = 2x2 + 5x – 8
Answer:
-93
Step-by-step explanation:
Step one:
given the expressions
[tex]f(x) = -4x + 7\\\\g(x) = 2x^2 + 5x- 8[/tex]
we want (fog)(-3).
but (fog) is
[tex]f(x) = -4x + 7\\\\\ (fog)=-4(2x^2 + 5x -8) + 7\\\\ (fog)=-8x^2-20x+32+7[/tex]
Step two:
fog(-3)= put x= -3 in (fog)(-3)=-8x^2-20x+32+7
[tex](fog)(-3)=-8x^2-20x+32+7\\\\ (fog)(-3)=-8(-3)^2-20(-3)+32+7\\\\ (fog)(-3)=-8*9+60+32+7\\\\ (fog)(-3)=-72-60+32+7\\\\ (fog)(-3)=-93[/tex]

Jacob and Sarah are saving money to go on a trip. They need at least $1850 in order
to go. Jacob mows lawns and Sarah walks dogs to raise money. Jacob charges $15
each time he mows a lawn and Sarah charges $10 each time she walks a dog. The
number of dog walks that Sarah has scheduled is no more than five times the
number of lawns Jacob has scheduled to mow. Sarah will walk at least 65 dogs.
Answer:
[tex]\textsf{Constraint 1}: \quad 15x+10y\geq 1850[/tex]
[tex]\textsf{Constraint 2}: \quad y \leq 5x[/tex]
[tex]\textsf{Constraint 3}: \quad y \geq 65[/tex]
Step-by-step explanation:
Inequality signs:
< Less than.≤ Less than or equal to.> More than.≥ More than or equal to.Given variables:
x = Number of lawns mowed.y = Number of dogs walked.Constraint 1Given information:
$15 = Charge for mowing a lawn.$10 = Charge for walking a dog.$1850 = Minimum amount needed for the trip.Therefore, the amount earned from mowing the lawns and walking dogs should be more than or equal to $1850:
[tex]\boxed{15x+10y\geq 1850}[/tex]
Constraint 2Given information:
The number of dog walks that Sarah has scheduled is no more than 5 times the number of lawns Jacob has scheduled to mow:Therefore, Sarah will walk less than or equal to 5 times the number of lawns mowed:
[tex]\boxed{y \leq 5x}[/tex]
Constraint 3Given information:
Sarah will walk at least 65 dogs.Therefore, Sarah will walk more than or equal to 65 dogs:
[tex]\boxed{y \geq 65}[/tex]
Two expressions are shown below.
Expression 1: 0.25x - 12
Expression 2: 18- 0.55x
For which value of x will the two expressions have the same value?
A
-100
B
-20
С C
7.5
37.5
Answer:
0.25x -12= 18- 0.55x (subtract 0.25x from both sides)
-12= 18 -0.80x (subtract 18 from both sides)
-30= -0.80x (divide each side by -0.80)
x= 37.5 (this is your answer)
The value of x in which the two expressions have the same value is 37.5
Here,
Given that;
Two expressions are,
Expression 1 : 0.25x - 12
Expression 2: 18- 0.55x
We have to find the value of x.
What is Mathematical expression?
A sentence with a minimum of two numbers or variables and at least one math operation is present, is called Mathematical expression.
Now,
The value of x will be find after equating both expressions as;
0.25x - 12 = 18 - 0.55x
Subtract 0.25x from both sides, we get;
- 12 = 18 - 0.80x
Subtract 18 from both side, we get;
- 30 = - 0.80x
Divide each side by -0.80, we get;
x= 37.5
Hence, The value of x in which the two expressions have the same value is 37.5

The sum of the measures of the angles of any triangle is 180. In a particular triangle, one angle is 40 greater than the smallest angle, and the third angle is 10 less than three times the smallest angle. Find the measure of the three angles.
Answer:
The smallest angle is 30 degrees, the second angle is 80 degrees and the third angle is 70 degrees
Step-by-step explanation:
let x = the smallest angle
This means that one angle is x+40, and the third angle is 3x-10. This make our equation:
x + 40 + 3x - 10 + x = 180
Combine like terms
5x + 30 = 180
Subtract 30 from both sides
5x = 150
Divide both sides by 5
x = 30
Plugging this in:
3x - 10 =
90 - 10 =
80
And for the other:
x + 40 =
30 + 40 =

Use the triangle shown on the right to answer the question. Which equation can you use to solve for a?
Answer:
B
Step-by-step explanation:
The equation that can be used to solve for 'a' is a/sin35° = 30/sin60°.
What is a triangle?A triangle is a three-sided closed-plane figure form by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know sine rule of triangles which states,
a/sinA + b/sinB + c/sinC.
We also know that the sum of all the interior angles in a triangle is 180°.
Therefore, The measure of angle B is 180° - (35 + 85)°.
= 60°.
So, The equation can you use to solve for 'a' would-be,
a/sin35° = 30/sin60°.
asin60° = 30sin35°.
(√3/2)a = 30×0.5735.
a = (30×0.5735)/0.866.
a = 17.205/0.866.
a = 19.87.

Is the given info enough to find the equation?
Yes, it is enough and the proof is as follows:
And equation is solved using:

jffjgnjfgnjgjfgjs
Answer:
90%
Step-by-step explanation:
1. We assume, that the number 5400 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 5400, so we can write it down as 100%=5400.
4. We know, that x% equals 6000 of the output value, so we can write it down as x%=6000.
5. Now we have two simple equations:
1) 100%=5400
2) x%=6000
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=5400/6000
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 6000 is what percent of 5400

According to the solving the work done if the gorilla reaches that height:
= 8400 ft lb.
What is meant by "work done"?The work performed by a force is defined as the sum of the displacement and or the component of both the applied force of both the object in the displacement direction. Work is accomplished when we push a block with a certain amount of force, "F," which causes the body to move more quickly. W = F stands for "work done."
The purpose of the work?Anytime a force transports something over a distance, work is performed. By multiplying the force by both the distance moved inside this direction of the force, you may determine the amount of energy transferred or work accomplished.
According to the given data:The effort put in by a 350-pound gorilla climbing a 24 foot staircase can be computed as:
(a) t = 10 sec
WF = (350 lb) (24 ft)
= 8400 ft lb (answer)
(b) t = 5 sec
WF = (350 lb) (24 ft)
= 8400 ft lb
work done does not depends on time.

= 8400 ft lb.
