Answer:
X = 4
Step-by-step explanation:
7x + 3 = 31
Step 1: Subtract 3 from both sides.
7x + 3 - 3 = 31 - 3
7x = 28
Step 2: Divide both sides by 7.
7x/7 = 28/7
Therefore, the answer is X = 4

Answer:
i) p = 4
ii) p = 8
iii) p = 12
Step-by-step explanation:
Here, we need to understand the initial relation
Mathematically, we have this as;
2.79 * p = c
So let us calculate the value of p for each value of c
i) 2.79p = 11.16
p = 11.16/2.79
p = 4
ii) 2.79p = 22.32
p = 22.32/2.79
p = 8
iii) 2.79p = 33.48
p = 33.48/2.79 = 12

Solve for x and found your answer to the nearest tenth.
Answer:
11.1
Step-by-step explanation:
To find the side measurement we have to use trig, and the trig function Cosine, or cos. We use the because cosθ=[tex]\frac{adjecent}{hypotenuse}[/tex]. So cosθ=[tex]\frac{x}{15}[/tex], then to isolate x multiply both sides by 15. Now we have 15cos42=x, plugging this into the equation we get that x=11.1
Mateo decide pedir un préstamo de 600 soles durante 2 años a un banco el cual le ofrece una tasa de interés anual de 16%calcula al interés simple y el monto total que pagará al término de 2 años
Answer:
192 and 792
Step-by-step explanation:
Given that
The principal is 600 soles
The Time period is 2 years
The Rate of interest is 16%
We need to find out the simple interest and the total amount paid at the end of 2 years
As we know that
SImple interest is
= Principal × rate of interest × time period
= 600 × 16% × 2
= 192
And, the amount is
= Principal + interest
= 600 + 192
= 792

what is the measure of each angle?
help pls!
will mark brainliest**
geometry!!
Answer:
A straight angle is the same as half the circle and is 180° whereas a right angle is a quarter of a circle and is 90°. You measure the size of an angle with a protractor. Or could be shown by an arc on the figure to indicate which angles that are congruent
Anika is hiking on a rectengular trail at the nation park there are four resting spots along the corners of the trail on the map they are marked with coordinates of -2,2) 1,2) 1,-2) and -2,-2 if rach unit represents 1 mile find the perimiter of the trail in miles using the coordinates
Answer:
The perimeter is 14 units
Step-by-step explanation:
Given
[tex]A = (-2,2)[/tex]
[tex]B = (1,2)[/tex]
[tex]C = (1,-2)[/tex]
[tex]D = (-2,-2)[/tex]
Required
Determine the perimeter
To do this, we simply calculate the distance between the sides of the rectangle i.e. AB, BC, CD and DA.
Distance (d) is calculated using:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
For AB
[tex]A = (-2,2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]B = (1,2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]AB = \sqrt{(-2 - 1)^2 + (2 - 2)^2} = \sqrt{9} = 3[/tex]
For BC
[tex]B = (1,2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]C = (1,-2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]BC = \sqrt{(1-1)^2 + (2--2)^2} = \sqrt{16} = 4[/tex]
For CD
[tex]C = (1,-2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]D = (-2,-2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]CD = \sqrt{(1 - -2)^2 + (-2 -- 2)^2} = \sqrt{9} = 3[/tex]
For DA
[tex]D = (-2,-2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]A = (-2,2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]DA = \sqrt{(-2--2)^2 + (-2-2)^2} = \sqrt{16} = 4[/tex]
So, the perimeter (P) is:
[tex]P = AB + BC + CD + DA[/tex]
[tex]P = 3 +4 + 3 + 4[/tex]
[tex]P = 14[/tex]
The perimeter is 14 units

Tameka is seeking a loan with a simple interest rate of 8% per year. If she borrows $5,000, how much interest will she be charged after 24 months?
Answer:
$800
Step-by-step explanation:
5000 × 8% = $400(interest in a year)
400 × 2 = $800(24 months=2years)
The measure of minor arc JL is 60°.
Circle M is shown. Line segments M J and M L are radii. Tangents J K and L K intersect at point K outside of the circle. Arc J L is 60 degrees.
What is the measure of angle JKL?
Answer:
m∠JKL = 120°
Step-by-step explanation:
The measure of an angle formed by a two tangents drawn from a point outside the circle is the the difference of the intercepted arcs
minor arc JL = 60 major arc JL = 360 - 60 = 300
m∠JKL = 1/2(300 - 60) = 1/2(240) = 120
Plz help me! Brainlist will be picked.
Answer:
$2.96
Step-by-step explanation:
1.15x = 3.40 x = last year's price. If there price was exactly the same, I would put 1x, but this year's price is 15% or .15 higher.
1.15x = 3.40 Divide both sides by 1.15 and round to the nearest cent.
x = 2.96
Check:
Last year + 15% (.15)
2.96 + .15(2.96)
2.96 + .44 rounded to the nearest cent
3.40

3. Scout is conducting a research project on traffic patterns
in her town. She realizes that at 6:00 AM each morning, the
traffic lights reset and function on a pattern. The traffic light
on Main St. turns red every 7 minutes. The traffic light on Elm
St. turns red every 15 minutes. At what time will both lights be
red at the same time?
Answer:
7:45
Step-by-step explanation:
Since they both turn red at differnt times, you have to find a multiple to find the time they will be both on
Main St: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105
Elm St. 15, 30, 45, 60, 75, 90, 105
They will both turn on 105 minutes or 1 hour and 45 minutes from 6
6 + 1 hr 45 min = 7:45
. Complete each equation with a number so that the equation has the stated solution(s). a) x^2+7=x^2+_____; no solution
Answer: other than 7
Step-by-step explanation:
Given
Equation is [tex]x^2+7=x^2+?[/tex]
For an equation to have no solution, the missing number can be any number other than 7
because if we put 7 then it justifies the equation i.e. [tex]7=7[/tex] while on the other hand for a number other than 7, it does not justify the equation.
