Answer:
All properties that were used to simplify the following problem:
1. commutative property of multiplication
2. multiplicative inverse 3. multiplicative identity
What is commutative property of addition?
The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.
The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.
For two numbers x and y, we have: x + y = y + x
Thus, if we take 3 numbers as a,b and c;
a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a
We have been given an expression;
2/7 • 53 • 7/2
53 • 2/7 • 7/2
53 • 1
53
Then all properties that were used to simplify the following problem:
1. commutative property of multiplication
2. multiplicative inverse
3. multiplicative identity

Answer:
70
Step-by-step explanation:
y=4. So replace y with 4. Your new equation is:
5 · 4² - 10
You can use basic math to finish the equation.
5 · 16 - 10
80 - 10
70
Answer: 70
Step-by-step explanation:
Substitute 4 for y in the expression (since y = 4)
Use PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction)
5 * (4)^2 - 10
= 5 * 16 - 10 Evaluate the exponent first
= 80 - 10 Then multiply 5 and 16
= 70 Finally, subtract

Answer:
y = 3
x = 1
y = 1.5
x = 2
Step-by-step explanation:
For the first x point, look at the graph where x is 0. When x is 0, y is 3. So the first one is 3. For the second one, there is a point on the graph where y is 4. Where y is 4, x is 1, so you the second answer is 1. For the third one, find the y point where x is -1. At the x value, -1, y is 1.5. For the last one, where y is 5, x is 2.
y is 3
x is 1
y is 1.5
x is 2

[WILL GIVE BRAINLY] An angle measures 122° more than the measure of its supplementary angle. What is the measure of each angle?
The measure of the angle will be equal to 58°.
What is the supplementary angle?
The supplementary angles are defined as the angles whose sum is equal to 180°
here the angle is 122° degrees more than its supplementary angle.
We know that the sum of the two supplementary angles is given as:-
Suppose the known and the unknown angles are A and B respectively.
∠A + ∠B = 180°
122 + ∠B = 180°
∠B = 180-122= 58°
Hence the measure of the angle will be equal to 58°.

Find the percentage of boxes that contain 48 raisins.
A. 16%
B 20%
C 14%
D 22%
Answer:
16%
Step-by-step explanation:
first you have to find out how many boxes are in the sample (count the dots - 25) Then you do 4/25 to find the percentage because there are 4 that have 48 raisins (.16) and move the decimal point to the left 2 (multiply by 100)
Answer:
a
Step-by-step explanation:
4 boxes are full of 48 raisins. 25 boxes total.
4/25 = 0.16
Convert 0.16 into a percentage by multiplying by 100.
0.16*100 = 16
so it should be 16%, correct me if wrong though.
Solve the system. y = -x + 3 and y = 2x
the solution is (__,__).
Explain your choice of method.
Answer: (1, 2)
which means
x = 1
y = 2
Step-by-step explanation:
y = -x + 3
y = 2x
Because both equations are set equal to y, they can be set equal to each other. The equations are ready to go to use Substitution method.
Substitute.
-x + 3 = 2x
Add x to both sides.
3 = 3x
Divide by 3.
3/3 = x
1 = x
We can put the 1 in for x in either equation.
y = 2x
y = 2(1)
y = 2
Putting x for 1 into the other equation is a good check.
y = -x + 3
y = -1 + 3
y = 2
So the x and y that work in both of these equations is:
x = 1 and y = 2
The form that was asked for was ( , ).
So the answer is
(1, 2).

Marissa did not change the direction of the inequality sign.
Step-by-step explanation:
Hello!
We can solve the inequality as well, and compare our steps to Marissa's to verify her steps.
Solve the inequality:[tex]-\frac x{12} > 7.8[/tex][tex](-12)\frac{x}{-12} > 7.8( -12)[/tex][tex]x < -93.6[/tex]We have the same number, but a different inequality sign. This is because we have to flip the inequality sign when multiplying and dividing by a negative number.
Therefore, the answer is the last option, Marissa has to flip the inequality sign when multiplying by a negative number.

What is the surface area of the triangular prism?
I need answer ASAP
Answer: 81 ft^2
Hello! The surface area of the rectangular prism will follow this process:
Right triangle area: (1/2)bh
So that 6ft (4.5ft) = 27ft^2/2; though when one multiplies that by 2 (as there are two right triangles), we get a surface area of 27ft^2.
For the rectangle's area, it's slightly more deviated since each face is different in length: bh
Face 1 = 3ft(7.5ft) = 22.5ft^2
Face 2 = 3ft(6ft) = 18ft^2
Face 3 = 4.5ft(3ft) = 13.5 ft^2
Thus, if we add these all together (27ft^2. + 22.5ft^2 + 18ft^2 + 13.5 ft^2), we get 81 ft^2

Answer:
Row 1: x=3; Row 3: y=18
Step-by-step explanation:
So to do this, look at where the line passes each of the x and y values it asks for within the graph.
In this question, x is the gallons of milk and y is the cost.
With the first part, it calls for the x value for when the y value is 6 dollars. With this, see where the line on the graph crosses 6 dollars. After doing this, you would see that the line passes over 6 dollars for when 2 gallons of milk are present. With this, write 3 under x.
With the other part, you do the same thing but now with the gallons of milk that are bought. So going up from where it says 6 gallons of milk on the graph, the line passes this over where it says $18. With this, write 18 under y.
