x = 10
Both angles measure 80°
—
Work:
the two angles are vertical angles, meaning that they are equal to each other, hence the equation will be this:
8x = x + 70
To solve, subtract x on both sides
7x = 70
Divide 7 on both sides to isolate the x
x = 10
Now, to find both of the angles measurement, plug in 10 for x.
10 + 70 = 80
8(10) = 80
Answer:
Equation:x+70=8x and both angles measure 80 degrees.
Step-by-step explanation:
Equation:x+70=8x
That is because vertical angles are congruent.
x+70=8x
-x -x
70=7x
x=10
Both angles measure 80 degrees.

Answer: y = -1/4x - 6
Step-by-step explanation: the slope is -1/4 because slope = rise/run, the rise is 1, and the run is 4 and the slope is negative. the y intercept is -6 because it passes through -6 at the y axis.
Answer:
-1/4x + -6
Step-by-step explanation:
The slope is -1/4 because slope = \(\frac{rise}{run}\),
So:
-\(\frac{1}{4}\) is the slope, also is negative.
The y intercept is -6 because it passes through -6 at the y axis.

This is easy, y=3.5x-3
Step-by-step explanation:
just do y2-y1/x2-x1, then you get slope which is M, is the formula, y=mx+b, then for B you pick one of the coordinates and fill in the formula, for example, i picked (2,-4), so i filled in -4=3.5(2)+b, then after multiplying 3.5*2=7, then 7-7 and 4-7, you get -3=b, so the full equation is y=3.5x+-3

13. $18.60
14. $15.79
Step-by-step explanation:
13.
Jeff starts off with $46.18
He then gives half of his money to his brother (so divide starting money by 2)
46.18 / 2 = 23.09
He now has $23.09
He then buys two donuts for $0.75 each ( 0.75 * 2 = 1.50 ) and a cup of coffee for $2.99 ( so he spent a total of 4.49 ) so we then subtract 4.49 from 23.09
23.09 - 4.49 = 18.6
He had $18.60 left over
14. 5 friends split a 65.20 bill at a restaurant
65.20 / 5 = 13.04
they also each left a $2.75 tip
13.04 + 2.75 = 15.79
They each payed $15.79
Answer: Jeff has $18 dollars and 6 cents or $18.6
Step-by-step explanation:
Half of $46.18 is $23.09. Then if he bought two donuts and each donut cost $0.75 then you plus $0.75 + $0.75 = 1.5. You then minus $ 1.5 from your current $23.09 dollars, which will equal $21.59. You have to minus the coffe amount which will is $2.99 . You minus $21.59 - $2.99 =$18.6.

Y+1 = -3(x-5), what is this equation converted to slope intercept form?
Answers
Answer:
y = -3x + 14
Step-by-step explanation:
The slope intercept form is y = mx + b. We need to get y + 1 = -3(x - 5) into y = mx + b form. Lets solve y + 1 = -3 (x - 5) first.
y + 1 = -3(x - 5)
Apply distributive property.
y + 1 = -3x + 15
Get y alone. Subtract 1 from each side.
y = -3x + 15 - 1
Subtract.
y = -3x + 14
Here is your answer. y + 1 = -3(x - 5) is now in slope intercept form. I hope this helps you!
Switch the 1 to the other side making it negative and distribute

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

The Cooper’s daughter, Ashley, was working a water stand during the building of the new game room. Ashley’s mother told her to buy bottled water for $0.75 each and mark them up 40% to sell at her stand. What is the amount of the markup? How much does Ashley charge for each bottled water?
Answers
Answer:
What is the amount of the Markup?
$0.3
How much does Ashley charge for each bottled water?
$1.05
Step-by-step explanation:
$0.75 is 100% of the cost.
40% is the percentage of the markup
Step 1: Add the 2 Percentages
100% + 40% = 140%
Step 2: Find 140% of $0.75, convert the percent to decimal for easier multiplication
140% x 0.75 = 1.4 x 0.75 = 1.05
= $1.05
What is the amount of the Markup?
1.05 - 0.75 = 0.3
= $0.3
How much does Ashley charge for each bottled water?
$1.05
