Answer:
N= -11Step-by-step explanation:
If 4 less than and is -15 then the following must be true .
n-4= -15
to solve this equation we need to add iv to both side
n-4+4= -15+4
this is simplified to the following
n= -11

- Ms. Ali needs to have her car repaired but does not want to spend more than $225
for the repairs. The mechanic says that the part needed for the repair will cost $78,
and that labor will cost an additional $35 per hour. Which inequality below
represents the greatest number of hours the mechanic can work without exceeding
Ms. Ali's budget? Use the steps below to solve. Then, HIGHLIGHT YOUR ANSWER.
a. 225 - 35x < 78
b. 35x + 78 > 225
c. 35 + 78x ≤ 225
d. 35x + 78 ≤ 225
Answer:
D
Step-by-step explanation:
Answer: D
Step-by-step explanation:
It has to be less than or equal to 225, and you know you only need one part, so it has to be 35x +78 _< 225
Saffron is very expensive spice. A shop selling saffron for $ 7.35 per gram.
Write the formula for the cost (y), in dollars, of g grams of saffron.*
a) y = 7.35g
b)g=7.35 y
c) y = 7.35+g
Answer:
A
Step-by-step explanation:
B is wrong because it's saying to multiply the cost by $7.35.
C is wrong because it's telling you to add the amount of grams to $7.35.
A is the correct answer because you have to mutiply the cost by the grams which is what a number by a variable means.
Saffron is one the most expensive spices in the world. Ms. Patel pays $123.51 for 2.3 grams of saffron. What is the price per gram?

How many solutions exist for the given equation?
} (x + 12) = 4x – 1
zero
one
two
infinitely many
Answer:
The given equation has one solution.
Step-by-step explanation:
Given equation is:
(x+12) = 4x-1
We will solve the equation to check how many solutions it has.
x+12 = 4x-1
Adding 1 on both sides
x+12+1 = 4x-1+1
x+13 = 4x
Subtracting x from both sides
x-x+13=4x-x
13 = 3x
x = 13/3
Hence,
The given equation has one solution.

What is the perimeter of the triangle, the left diagonal side is 6.1in, the right diagonal side is also 6.1in, the bottom line is 7in, and there is a line in the middle from top to bottom which is 5in. What is the perimeter of the triangle?
Answer:
19.2 inches
Step-by-step explanation:
6.1 + 6.1 + 7 = 12.2 + 7 = 19.2
perimeter is the outside distance of the shape so you don't need to know the altitude (or height) equals 5.

Steve is buying an $1160 T.V on the installment plan. He makes a down payments of 200 he has to make monthly payment of 55.25 fo 21/2 years what is his finance charge
Answer:
Finance charge = $200
Step-by-step explanation:
Cost of the T.V. = $1160
Steve did the down payment = $200
Monthly payment done by Steve = $22.5
Duration for the periodic payments = 2.5 years
Number of periodic payments to be done = 12 × 2.5
= 30
Amount paid in periodic payments = Number of periodic payments done × amount paid in each month
= 30 × $55.25
= $1657.5
Total payment done = Down payment + Amount paid in periodic payments
= $200 + $1657.5
= $1857.5
Therefore, finance charges = Total payments done - cost of T.V.
= 1857.5 - 1657.5
= $200

Find the slope of the line that passes through (5,9) and (3,9)
Answer:
Since the Y coordinate is constantly 9, it is a horizontal line.
Step-by-step explanation:
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 9) and (x₂, y₂ ) = (3, 9)
m = [tex]\frac{9-9}{3-5}[/tex] = [tex]\frac{0}{-2}[/tex] = 0

Step-by-step explanation:

The statement that best explains the relationship between lines FG and HJ is "They are not perpendicular because their slopes are not negative reciprocals."
What is a slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
To find the slope of a line passing through two given points, we use the formula:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
For line FG, the two points are F(-4, 1) and G(0, -2):
slope of FG = (-2 - 1) / (0 - (-4)) = (-2 - 1) / 4 = -3/4
For line HJ, the two points are H(-4, -2) and J(0, 4):
slope of HJ = (4 - (-2)) / (0 - (-4)) = 6/4 = 3/2
The slopes of lines FG and HJ are not equal. However, we can see that they are not negative reciprocals of each other:
slope of FG = -3/4
slope of HJ = 3/2
Therefore, lines FG and HJ are not perpendicular because their slopes are not negative reciprocals of each other.

anyone got an answer for this (don't mind the 160 i put. That answer is wrong)
Answer:
140°
Step-by-step explanation:
Angles in a triangle add up to 180
we can see it's an isosceles triangle so the base angles are the same
The missing angle inside the triangle would be...
180 - (70 + 70) = 40°
Angles on a straight line add up to 180
so 180 - 40 = 140°

At a campground, kayak rental company A charges a fixed amount of $10 plus $8 per hour for renting a one-person kayak. Company B charges a fixed amount of $6 plus $10 per hour for a one-person kayak.
Answer:
2hours
Step-by-step explanation:
Given data
Company A
charges a fixed amount of $10 plus $8 per hour
let the number of hours be x
and the total be y
y= 10+8x----------------1
Company B
charges a fixed amount of $6 plus $10 per hour for a one-person kayak.
let the number of hours be x
and the total be y
y= 6+10x----------------2
Equate 1 and 2 above
10+8x= 6+10x
collcet like terms
10-6= 10x-8x
4= 2x
x= 2hours
Hence after 2 hours the charges will be the same

The standard equation of a circle with center (h, k) and a vertical axis of symmetry is (x - h)² + ( y - k)² =r² A circle's center is (3,- 2) and the radius is 12. Which equation models the circle?
A)(x - 3) ² + (y + 2) ² = 12
B)(x + 3) ² = (y + 2) ² = 12
C) (x - 3) ² = (y + 2) ² = 144
D)(x + 3)² – ( - 2) ² = 144
NOTES: The general equation of a circle is (x – h)2 + (y – k)2 = r2, where (h, k) represents the location of the circle's center, and r represents the length of its radius.

6(x-4)-x=6x+4 one solution, no solution or infinite solution
Answer:
no solution
Step-by-step explanation:
Given
6(x - 4) = 6x + 4 ← distribute left side
6x - 24 = 6x + 4 ( add 24 to both sides )
6x = 6x + 28 ( subtract 6x from both sides )
0 = 28 ← not possible
This indicates the equation has no solution

11√2 is the right answer.Find the volume of each figure. Round your answers to the nearest hundredth, if necessary. Leave your answers in terms of pi for answers that contain pi.
Answer:
125πkm
Step-by-step explanation:
The figure shown is a cylinder :
Volume of a cylinder is obtained using tbe relation :
V = πr²h
Where ; r = Radius ; h = height
r = 5km ; height = 5km
Hence,
V = π * 5² * 5
V = 25 * 5 * π
V = 125πkm
