Answer:
5x - 4 = 11
1/2x + 15 = 9
Step-by-step explanation:
I dont exactly know how u would show work.
If it says something is less than a number, then it will be at the back of the equation. So skip that part and u will see it says five times a number. The number is unknown therefore it will a variable (i chose x to be the variable). 5 times x is 5x. Minus the 4 would be 5x - 4. Then it says the equation equals 11. So 5x - 4 = 11.
If it says something is more than a number, it can be on either side of the equation using the commutative property of addition. But if we want to consider it being like subtraction, then it also will be in the back of the equation. A half is one over two (1/2). A half of x is 1/2x. Plus the 15 would be 1/2x + 15. It then states that the equation equals 9. So 1/2x + 15 = 9.

It is an isosceles triangle which has two angles of the same measurement, Pretty easy to figure out.
Answer:
x= 64 ansdy=52
Step-by-step explanation:
Since the 64 line is congruent to the "x" line, it must be 64. A triangle's angles equal 180 so 180-64-64= 2 giving you "y"
ermest works in the shipping department loading shipping crates with boxes. Each empty crate weighs 150 lb. How many boxes, each weighing 35 lb, can Ernest put in the crate if the total weight is to be no more then 850 lb?
Answers
Max weight of the crate - the empty crate/ by 35 (the weight of the individual boxes)
850-150=700
700 lbs is the remaining weight available that can be filled with 35 lb boxes, to find out the number of boxes that can be added to the crate, divide 700 by 35.
700/35 = 20
Ernest can put in 20 boxes in the crate.

Answer:
18
Step-by-step explanation:
Hello there. This problem can be easily solved by setting up a ratio.
This would be as follows
[tex]\frac{90percent}{100}[/tex] x [tex]\frac{x}{20 }[/tex]
after solving for x we find that 90% of 20 should be 18.

What is the inverse of the function g(x)=5(x-2)g(x)=5(x−2)g, left parenthesis, x, right parenthesis, equals, 5, left parenthesis, x, minus, 2, right parenthesis
Answers
Answer:
(x+10)/5
Step-by-step explanation:
Given the function
g(x) = 5(x-2)
Open the parenthesis
g(x) = 5x-10
To find the inverse we need to follow the steps;
Step 1; make y as g(x)
y = 5x-10
Step 2; replace y with x;
x = 5y - 10
Step 3; make y the subject of the formula;
x = 5y-10
5y = x+10
y = (x+10)/5
Step 4: substitute y as g^(-1)(x)
g^(-1)(x) = (x+10)/5
Hence the inverse of the function is (x+10)/5
Answer: x+10/5

The Mad Hat Company must ship two different-sized boxes: The small ones cost them 45 cents each and weigh 6 ounces, and the large ones weigh 25 ounces and cost $1.20 each. The total shipment this morning weighed 20 pounds 7 ounces and cost $18.45. How many packages of each size were shipped?
Answers
Given :
The Mad Hat Company must ship two different-sized boxes: The small ones cost them 45 cents each and weigh 6 ounces, and the large ones weigh 25 ounces and cost $1.20 each.
The total shipment this morning weighed 20 pounds 7 ounces and cost $18.45.
To Find :
How many packages of each size were shipped.
Solution :
We know, 1 pound = 16 ounces.
So, 20 pound = 20×16 = 320 ounces.
Let, number of large and small box are l and s.
So,
25l + 6s = 327 ...1)
0.45s + 1.20l = 18.45 ...2)
Solving both the equations, we get :
x = 9 and y = 17
Therefore, package smaller and big size are 17 and 9 respectively .
Hence, this is the required solution.

Alex is thinking of a number. Twenty less
than one fourth of the number is -45. Find Alex’s number.
i need the equation.
Answers
Answer:
¼x - 20 = -45
¼x = -25
x = -100
Step-by-step explanation:
To solve this we can write it out into an equation. Let's use the variable x for the number Alex is thinking of. Then we can take out each information to see what it means mathematically. We need to see what operation is being done.
"twenty less than one fourth of the number" The second part is using mutiplication, as indicated by "of." So we would write a quarter (one fourth) times the number (x). The first part is using subtraction, indicated by "less than." This would be expressed by "- 20"
Putting it together:
¼x - 20
"is -45" this is joining the expression to an equation. So this would simply mean " = -45 " Then our equation is:
¼x - 20 = -45
Now we can solve it.
¼x - 20 = -45
¼x = -25
x = -100

Answer:
(x,y)=(-2,3)
Step-by-step explanation:
Since both expressions -3x-3 and x+5 are equal to y, set them equal to eachother forming an equation in x
-3x-3=x+5
solve the equation for x
x= -2
substitute the given value of x into the equation y=x+5
y= -2 +5
solve the equation for y
y=3
the possible solution of the system is the ordered pair (x,y)
(x,y) = (-2,3
check if the given ordered pair is the solution of the system of equations
{3= -3x(-2) -3
{3= -2 +5
simplify the equalitites
{3=3
{3=3
since all the equalitites are true, the ordered pair is the solution of the system
(x,y)=(-2,3)

Answers
Answer:
y = 2x -3
Step-by-step explanation:
to solve for y, simply isolate the y so in this case move 2x to the right side of the equation in which it becomes -y= -2x +3 and then divide by -1 which is beside the -y essentially cause y cannot be negative so then the equation becomes y = 2x -3
Answer:
y=2x-3
Step-by-step explanation:
2x-y=3
-2x on both sides of the equal sign which leaves you with -y=-2x+3
divide both sides by negative 1
y=2x-3
