Answer:
2 [tex]\frac{3}{8}[/tex]
Step-by-step explanation:
3/4 + 5/6 (lowest common denominator = 12)
= 9/12 + 10/12
= 19/12
19/12 ÷ 2/3 (reciprocate 2/3 to replace division sign by multiplication sign)
= 19/12 x 3/2
= 57/24
= 19/8
= 2 [tex]\frac{3}{8}[/tex]

Find the measures of angle 1 and angle 2. State the theorem or postulate that justifies your answer,
Answer:
Angle 2 = 55
Angle 1 = 125
Step-by-step explanation:
Considering the line vertical lines are parallel:
Angle 2 and angle with measure of 125 are supplementary and their sum is = 180
So m<2 = 180 - 125 = 55
For angle 1:
Again since the vertical lines are parallel:
Angle 1 and angle with given measure 125 are alternate and has same measurement.
Answer:
Angle 2= 55 degrees
angle 1= 125 degrees
Step-by-step explanation:
Angle 2 uses SA, 180-125=55
angle 1 is parallel to the 125 degree line

HELPPPPP plsssss i need this answer ASAP
Answer:
0.05 in decimal form or 1/20
Step-by-step explanation:
Since there are 20 blocks, we are going to divide 1 by 20.
Result: 00.5
To get it in fraction form we are going to multiply 1/4 by 1/5 and get 1/ 20 because 4 x 5 = 20. There is no way to simplify this.
Therefore, your answer would be 1/20.

How many solutions does the equation have?
Answer:
Infinitely many
Step-by-step explanation:
They both equal the same equation
Answer:
All real numbers are solutions.
Step-by-step explanation:
4(z−5)+2=4z−18
Step 1: Simplify both sides of the equation.
4(z−5)+2=4z−18
(4)(z)+(4)(−5)+2=4z+−18(Distribute)
4z+−20+2=4z+−18
(4z)+(−20+2)=4z−18(Combine Like Terms)
4z+−18=4z−18
4z−18=4z−18
Step 2: Subtract 4z from both sides.
4z−18−4z=4z−18−4z
−18=−18
Step 3: Add 18 to both sides.
−18+18=−18+18

Find the slope and y-intercept of the graph of the linear equation.
y+3=2/3x
Answer:
Slope: 2/3
y-intercept: -3
Step-by-step explanation:
Subtracting both sides of the equation by 3 to make it in 'y=mx+c' form:
y + 3 - 3 = 2/3x - 3
y = 2/3x - 3
Seeing this,
m = 2/3
c = -3
Since m is the slope, the slope is 2/3
Since c is the y-intercept, the y-intercept is -3

Answer:
-5x-2=11
+2
-5x=9
÷-5
x=1.8
Step-by-step explanation:
Answer:
x = -2.6
or x=-2 and 3/5
Step-by-step explanation:
Simplifying
11 = -5x + -2
Reorder the terms:
11 = -2 + -5x
Solving
11 = -2 + -5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5x' to each side of the equation.
11 + 5x = -2 + -5x + 5x
Combine like terms: -5x + 5x = 0
11 + 5x = -2 + 0
11 + 5x = -2
Add '-11' to each side of the equation.
11 + -11 + 5x = -2 + -11
Combine like terms: 11 + -11 = 0
0 + 5x = -2 + -11
5x = -2 + -11
Combine like terms: -2 + -11 = -13
5x = -13
Divide each side by '5'.
x = -2.6
Simplifying
x = -2.6

Which one of the following values of k makes the trinomial 9x^2 + kx + 64 a perfect square
a 24
b 48
c 16
d 42
Answer:
it is C 16
Step-by-step explanation:
x² - kx + 64
Since we are looking for a perfect square, then we need to take the square root of 64 to find the factors: √64 = 8
So, the factors are: (x - 8)(x - 8)
Foil (or distribute) to get: x² - 16x + 64 The k-value is 16

For each pair of points, find the slope of the line that passes through both points. If you get stuck, try plotting the points on graph paper and drawing the line through them with a ruler. Use fractions, not decimals, and make sure to simplify all fractions.
Answer:
a. 1 1/2 (or 3/2)
b. 2/3
c. 1
d. 1
Step-by-step explanation:
Part A: (1,1) (7,5)
To determine the slope, you will use the equation m=(y2-y1)/(x2-x1). Keep in mind that it doesn't matter what point you use for (x1, y1) or (x2, y2).
Let's plug in the numbers for part a:
m=(7-1)/(5-1)
Let's then solve the problems inside the parentheses:
m=6/4
And finally, we simplify:
m=3/2 (or 1 1/2 depending on what your teacher wants for an answer)
For these others, I will just go through the steps and not explain them, if you need help or don't understand something I'm doing, either look back at what I did for part a or comment on this answer.
Part B: (1,1) (5,7)
m=(5-1)/(7-1)
m=(4/6)
m=2/3
Part C: (2,5) (-1,2)
m=(-1-2)/(2-5)
m=(-3/-3)
m=1
Part D: (2,5) (-7,-4)
m=(-7-2)/(-4-5)
m=(-9/-9)
m=1
Show a different way to solve 25 x 28
Answer:
700=25x28
Step-by-step explanation:
The product of the two given numbers is 700.
The given expression is 25 × 28.
We need to find the product of these two numbers in different ways.
What is the distributive property of multiplication?The distributive property of multiplication over addition states that multiplying the sum of two or more addends by a number gives the same result as multiplying each addend individually by the number and then adding the products together. This property of multiplication over addition is used when we need to multiply a number by a sum.
Now, direct multiplication 25 × 28=700
Using distributive property we get 25 × (20+8)
=25 × 20 + 25 × 8
=500 + 200
=700
Therefore, the product of two given numbers is 700.

Given the system of equations, what is the solution?
2x + y = 7
2x - 3y = -1
Answer:
[tex](\frac{5}{2}, 2)[/tex]
Step-by-step explanation:
Hi there!
We are given this system of equations:
2x + y = 7
2x - 3y = -1
And we want to find the solution
There are multiply ways to solve systems of equations, but let's solve this one by elimination, where we will add the two equations together to clear one of them, solve for the un-cleared variable, and then use the value of the un-cleared variable to solve for the cleared one
Before clearing a variable, we need to make sure that the signs on the variables are opposites; for example, -3 and 3, which will add together to get 0
We can multiply the equations beforehand if needed in order to manipulate the numbers.
For example, we can multiply the second equation by -1 in order to switch the signs of each number in that equation:
-1(2x-3y=-1)
-2x+3y=1
Now the signs in front of x are 2 and -2, so we can add the equations together to clear them:
2x + y = 7
-2x + 3y = 1
Add the equations together
4y = 8
Divide both sides by 4
y=2
Now let's use 2 as y to solve for x
In the first equation, substitute 2 for y:
2x + 2 = 7
Subtract 2 from both sides
2x = 5
Divide both sides by 2
[tex]x=\frac{5}{2}[/tex]
As a point, the answer is [tex](\frac{5}{2}, 2)[/tex]
