Which equation can be used to solve for in the following diagram?
Choose 1 answer:
А) 105 + (50 – 70) = 90
B) 105 + (5x – 70) = 180
C) 105 = (5x – 70)
D) 105 +90 = (5x - 70)
Answer:
C) 5x-70=105
Step-by-step explanation:
As marked in the graph, angle 105 and angle (5x-70) equal to each other because they are vertically opposite angles therefore we have equation C)

Sue is 15 years older than Mike. in 5 years mikes’s age will be ½ sue’s age. What is the present age of each?
Show work!!!!
Answer:
5
Step-by-step explanation:
Sue in 5 years would 20, meaning Mike would be 10. Subtract 5 from Mike to get their current age.
Answer:
Mike= 10 years old
Sue= 25 years old
Step-by-step explanation:
Let the present age of Sue be s years old, while that of Mike be m years old.
Present
s= m +15 -----(1)
In 5 years
Sue's age= s +5
Mike's age= m +5
Given that Mike would be ½ of Sue's age in 5 years,
m +5= ½(s +5)
Multiply both sides by 2:
2(m +5)= s +5
Expand:
2m +10= s +5
2m +10 -5= s
s= 2m +5 -----(2)
Substitute (1) into (2):
m +15= 2m +5
2m -m= 15 -5
m= 10
Substitute m= 10 into (1):
s= 10 +15
s= 25
Thus, the present age of Mike is 10 years old and the present age of Sue is 25 years old.

An item is priced at $13.75. If the sales tax is 7%, what does the item cost including sales tax?
Answer:
divide 7/100 which is 0.07
multiply that by 13.75, and you get 0.96
13.75+0.96= $13.20
(this is including sales tax)
Answer:
$12.78
Step-by-step explanation:
I THINK you are supposed to multiply the original price (13.75) by the sales tax as a decimal (0.07) and then subtract that answer from, the original, amount.

Solve 2x2 + x − 4 = 0
Answer:
x = 0
Step-by-step explanation:
hi there!
im not sure if the x between the 2's is a x as in a variable or if it is multiplication sign. im going to solve the problem as if it is a multiplication sign but if that is wrong then please let me know!
2 * 2 + x - 4 = 0
is our equation that we are working with ^
first step is, following the pemdas we multiply *2 with its self
( ^ parentheses, exponents, multiplication/ division making sure to solve it left to right, addition and subtraction still making sure to follow the left to right rule )
2 * 2 + x - 4 = 0
2 * 2
= 4 + x - 4 + 0
then we add positive 4 and negative 4 together, canceling eachother out the giving us the answer of x = 0
4 + x - 4 + 0
4 + - 4 = 0
x = 0
i hope this helps you! have a good rest of your day :)

Find the volume of a right circular cone that has a height of 18.5 in and a base with a diameter of 17.5 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
Step-by-step explanation:
volume of cone formula: V = 1/3 πr²h
r = 1/2 d
r = 1/2 (17.5)
r = 8.75 in
V = 1/3 (π8.75²)(18.5)
V = 1483.26 in²

Scale: 1 cm represents 10 miles
Ismael's house is the same distance
from town A and town B.
His house is exactly 20 miles from town C.
Use the x tool to show all the possible positions of Ismael's house.
You must show all your construction lines.
[5]
There are no possible positions for Ismael's house.
In this case, we need the following geometrical constructions:
1) Given that Ismael's house has the same distance from towns A and B, we must create a line segment between A and B and perpendicular line passing through the midpoint of line segment AB.
2) Since Ismael's house is 20 miles away from town C, we must create a circle centered at C.
All possible positions of Ismael's house are the set of points where both the perpendicular line and the circle intercepts each other. After making all operations defined above, we conclude that there are no possible positions for Ismael's house.
