the house on one side of Elm Street follows a pattern the first five houses are numbers 41, 47 53, 59 and 65 if the pattern continues which of the following could be a house number on Elm Street. A- 75, B- 77, C- 81, D- 87
Step-by-step explanation:
Notice that:
47 - 41 = 6,53 - 47 = 6,59 - 53 = 6, 65 - 59 = 6.Every house number on the side of Elm Street is 6 more than the previous one.
If we continue this pattern, we will see the following house numbers:
65 + 6 = 71,71 + 6 = 77,77 + 6 = 83,83 + 86 = 89.Out of the options given, the only one whose number is on the side of Elm Street is 77. (B)

y=-3x + 10
y = -2x + 6
Substitution method
Answer:
x=4 and y=−2
Step-by-step explanation:
y=−3x+10;y=−2x+6
Step: Solve y=−3x+10for y:
Step: Substitute−3x+10foryiny=−2x+6:
y=−2x+6
−3x+10=−2x+6
−3x+10+2x=−2x+6+2x(Add 2x to both sides)
−x+10=6
−x+10+−10=6+−10(Add -10 to both sides)
−x=−4
-x/-1 = -4/-1 (Divide both sides by -1)
x=4
Step: Substitute4forxiny=−3x+10:
y=−3x+10
y=(−3)(4)+10
y=−2(Simplify both sides of the equation)
Answer:
Solution is the point (4, -2)
Step-by-step explanation:
use the expression for y from the first equation in the second equation:
then the equation y = - 2 x + 6 becomes:
- 3 x + 10 = - 2 x + 6
add 3 x to both sides
10 = 3 x - 2 x + 6
10 = x + 6
subtract 6 from both sides
x = 4
Now replace x with 4 in the first equation to find y:
y = - 3 x + 10 = - 3 (4) + 10 = - 12 + 10 = -2
Therefore this is the point solution to the system:
(4, -2)
after completing the square what are the solutions to the quadratic equation below
x²-5x-6=3
Answer:
x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 5 x - 6 = 3
Hint: | Solve the quadratic equation by completing the square.
Add 6 to both sides:
x^2 - 5 x = 9
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 25/4 to both sides:
x^2 - 5 x + 25/4 = 61/4
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 5/2)^2 = 61/4
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 5/2 = sqrt(61)/2 or x - 5/2 = -sqrt(61)/2
Hint: | Look at the first equation: Solve for x.
Add 5/2 to both sides:
x = 5/2 + sqrt(61)/2 or x - 5/2 = -sqrt(61)/2
Hint: | Look at the second equation: Solve for x.
Add 5/2 to both sides:
Answer: x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2

Answer: a) one central angle is QPR
b) arc QTS is a semicircle
c) arc QR is a major arc
d) arc QTR = 235
e) arc QR = 125
Step-by-step explanation:
A central angle is an angle with its vertex as the midpoint of the circle.
A semicircle is half of a circle. Segment QS goes through the midpoint P splitting the circle in half : arc QTS and arc QRS are both semicircles.
The degree of a central angle is equal to the arc it encompasses. Central angle QPR is equal to 125, therefore arc QR is equal to 125 as well.
Given this information we can now find the remaining arc QTR. A circle is equal to 360 degrees. We know part of the circle is 125 degrees which means the remaking portion must be 235 degrees.
360 - 125 = 235
What is the sales tax on a jacket priced at $675 if the sales tax rate is 6%? The sales tax is $
Answer:
$ 37.50
Step-by-step explanation:
We can rewrite this problem as: What is 6% of $625?
"Percent" or "%" means "out of 100" or "per 100",
Therefore 6% can be written as 6/100.
When dealing with percents the word "of" means "times" or "to multiply".
Finally, lets call the sales tax we are looking for "t".
Putting this altogether we can write this equation and solve for t while keeping the equation balanced:
t=6100×$625
t=$3750100
t=$37.50
Answer:
40.50
Step-by-step explanation:
Sales price x sales tax rate = sales tax
675 x .06 (6%) = 40.50

9514 1404 393
Answer:
19.25 miles
Step-by-step explanation:
Antoine's rate before lunch was ...
(5.25 mi)/(3 h) = 1.75 mi/h
Then his rate after lunch was ...
2×(1.75 mi/h) = 3.5 mi/h
The distance he hiked after lunch was ...
distance = speed × time
(4 h)×(3.5 mi/h) = 14 mi
The distance Antoine hiked is the total of his before-lunch distance and his after-lunch distance:
5.25 mi + 14 mi = 19.25 mi

preschool has a student to teacher ratio of 5:2 which of the following ratios is equivalent to this ratio?
A 45 teachers to 18 students
B 45 students to 18 teachers
C 35 students to 10 teachers
D 10 students 7 teachers
Answer:
C
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
First you do 5/2 to solve the ratio! That equals 2.5 btw. Then you have to selected the answer choice that is equivalent to that. So I just divided all them until I got a radio equal to 2.5! 45/18 equals 2.5 also! Therefore A (45 teachers to 18 students) was the correct choice!

ANSWER FOR A BRAINLIEST Solve the system of two variables by substitution
Answer:
Substitution is when you isolate a variable-
3) We can divide the first equation by 6 to get x+y=-1, then isolate to get y=-1-x. We plug this into the second equation to have 3x+(-1-x)=-13. We simplify and get 2x=-12 so x=-6. We plug this back into the first equation and get -6+y=-1 so y=5. So the answer as an ordered pair is (-6,5).
4) We can isolate the second equation to get x=2y+11. We substitute this into the first equation to have -7(2y+11)-2y=-13. We simplify and get -16y=64 so y=-4. We plug this back into the second equation and get x+8=11 so x=3. So the answer as an ordered pair is (3,-4).

101+ 6x-5=180
6x=84
x=14
hope this helps!
Answer:
x = 14
Step-by-step explanation:
Since m || n, the two adjacent angles (101° and (6x-5)) must add up to 180°.
180° - 101° = 79°. Therefore, 6x - 5 = 79.
Add 5 to both sides, and the equation is 6x = 84.
Then divide both sides by 6 to get x = 14.
