Answer:
[tex]\angle A=113\textdegree[/tex]
Step-by-step explanation:
We know that ∠A and ∠B are vertical angles.
Remember that vertical angles have the same measure. So:
[tex]\angle A=\angle B[/tex]
Substitute them for their equations:
[tex]7x-20=6x-1[/tex]
Solve for x. Add 20 to both sides:
[tex]7x=6x+19[/tex]
Subtract 6x from both sides. So, the value of x is:
[tex]x=19[/tex]
To find ∠A, we can use its equation again:
[tex]\angle A=7x-20[/tex]
Substitute 19 for 7:
[tex]\angle A=7(19)-20[/tex]
Multiply and subtract:
[tex]\angle A=133-20=113\textdegree[/tex]
So, the value of ∠A is 113°.
And we're done!

what is 20x+8 =4÷2 please help
Answer:
- 0.3
Step-by-step explanation:
Step 1:
20x + 8 = 4 ÷ 2 Equation
Step 2:
20x + 8 = 2 Divide
Step 3:
20x = - 6 Subtract 8 on both sides
Step 4:
x = - 6 ÷ 20 Divide
Answer:
x = - 0.3
Hope This Helps :)
Answer:
x = - 3/10
Step-by-step explanation:
Hi !
20x + 8 = 4 : 2
20x = 2 - 8
20x = - 6
x = - 6/20
x = - 3/10
Good luck !

Step-by-step explanation:
6≥−6(a+2) solve and find the awnser
Answer:
[tex] - 3 \geqslant a[/tex]
Step-by-step explanation:
[tex]6 \geqslant - 6(a + 2)[/tex]
distribute -6 inside the parentheses
[tex]6 \geqslant - 6a - 12[/tex]
add 12 to both sides
[tex]18 \geqslant - 6a[/tex]
divide by -6 to isolate the variable
[tex] - 3 \geqslant a[/tex]
Answer:
-3<=a
Step-by-step explanation:
1. Get the -6 away, so multiply everything by -6. 6*-6 >= -6*-6(a+2)
2. This becomes -1 <= a+2 Since if you multiply or divide anything by a negative number, you have to reverse the inequality sign.
3. Subtract 2 to get a by itself -1-2 >= a
4. This becomes -3 >= a which is the right answer.
(Just so you know >= and <= means less than or equal to and more than or equal to.)

Step-by-step explanation:
j(x)=−45x+7; j(x)=−5
Answer:
x = 4/15
Step-by-step explanation:
Step 1: Define
j(x) = -45x + 7
j(x) = -5
Step 2: Substitute and Evaluate
-5 = -45x + 7
-12 = -45x
x = 4/15

What is the slope of the line passing through the points (-3, 4) and (2, – 1)?
Answer:
m=-1 or -1/1 (same thing)
Step-by-step explanation:
(y2-y1/x2-x1)
(-1-4)/(2-(-3))=-5/5=-1
Answer:
-1
Step-by-step explanation:
The slope of a line can be written as [tex]\frac{\triangle{y}}{\triangle{x}}[/tex] or [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]. Plugging in the values gives us [tex]\frac{-1 - 4}{2 - (-3)} = \frac{-5}{5} = \boxed{-1}[/tex]

1.) Which of the following equations is not a linear equation?
A) y = -4
B)X 3 = 1
C) 2x -4y =1
D) y= X - 2
2.) Find the value of y that makes the equation y= -x + 5 true, when x =-4
A.) -1
B.) 2
C.) 1
D.) 9
3.) Find the value of y that makes the equation y= x + 1/4 true, when x = - 1/4.
A.) -4
B.) 0
C.) 1
D.) 4
Answer:
1) B
2) D
3) B
Step-by-step explanation:
For question 1:
Assuming that option B is [tex]x^3=1[/tex], it is not a linear function.
Linear functions have equations that do not have exponents.
For question 2:
[tex]y=-(-4)+5\\\\y=4+5\\\\\boxed{y=9}[/tex]
The option is D.
For question 3:
[tex]y=x+\frac{1}{4}\\\\ y=-\frac{1}{4}+\frac{1}{4}\\\\ \boxed{y=0}[/tex]
The option is B.

The speed of an object can be found by taking the distance it travels and dividing it by the time it takes to travel that distance. An object travels 100 feet in 2.5 seconds let the speed, S, be measured in feet per second. True or false: the equation
Answer:
True the speed S in in Feet/secondStep-by-step explanation:
In this problem we are required to solve for the speed of an object.
given that the expression to solve for the speed is expressed as
speed= distance/time
given data
distance=100 feet
time=2.5 seconds
substituting our given data into the expression we can solve for speed as
speed (S)=100/2.5
S= 40feet/seconds
upon substituting our data the speed S was found to be 40feet/s
True the speed S in in Feet/second
I need help graphing 2x - 6y = 42 I'm just really lazy
Answer:
We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)
Step-by-step explanation:
Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)

Answer:
candy 7
packs 5
Step-by-step explanation:
Answer:
Option A!
Step-by-step explanation:
Hey there!
To figure out the ratio of candies per packs, we divide 21 (candy) by packs (3) and we get 7. This means that there are 7 candies per pack! So, in 1 pack, there are 7 candies and when there are 35 candies, we divide 35 by 7 and get 5.
So, in one pack there are 7 candies and there are 35 candies in 5 packs.
Option A. Candy: 7 Packs:5

While shopping at a music store, Rick bought 7 CD’s, all at the same price. The tax was $6.50 and the total was $66.00. What was the price of each CD?
Answer:
$8.50
Step-by-step explanation:
Subtract the tax from the total price:
66 - 6.50
= 59.5
Then, divide this by 7 to find the cost of each CD:
59.5/7
= 8.5
So, the price of each CD was $8.50
Answer:
8.50
Step-by-step explanation:
66-6.50=59.50
59.50 divided by 7 =8.50

JUST THE FIRST ONE:
1 is less than or equal to m, m is less than 6
Start your point at 1, with a closed circle going to the right
Second point, place at 6 with an open circle going to the left
help find the slope of the line
Answer:
-3/5
Step-by-step explanation:
When finding the slope, think of it as rise/run.
Rise= up/down
run=left or right
So looking at the line, it is pointing towards -inf so the slope is negative
Then we look at 2 points.
i.e. (0,2) and (-5,5) and do the rise over run technique (or just subtract) and you get your answer!
