Step-by-step explanation:
Basically 15x<30 is saying that 15x is less that 30. So that means x can be any number as long as when multiplied to 15 it has to be less then 30. So they only number available is 1. So 15(1)<30. Im not sure what the question is but X=1
Answer:
x < 2 or (-∞,2)
Step-by-step explanation:
Treat the inequality sign like an = sign at this point. Don't make it more complicated than it really is. So, to figure it out, you first need to divide each side by 15 so you can get x all by itself:
[tex]\frac{15x}{15} < \frac{30}{15}[/tex]
Now we have:
x < [tex]\frac{30}{15}[/tex]
We know (using simple math) that 30 divided by 15 is 2, which gives us:
x < 2.
In interval notation, this would be (-∞,2). [Remember that the parentheses show that the interval does NOT include the specified numbers, which is what < denotes in our equation.] Hope this helped!

Answer:
Step-by-step explanation:
Each point of intersection with the system of equations was matched.
what is a linear equation?Any equation in the form [tex]ax+by+c=0[/tex] is called a linear equation where a,b,c∈R.
In the given diagram, to find the intersection of two lines, solve the equations of two lines.
1)[tex]\left \{ {{y=-2x-3} \atop {y=2x-1}} \right.[/tex]
The solution of the given system of equations comes to be x=-1/2 and y=-2.
So they will intersect at (-1/2, -2) i.e. same as the graph.
2)[tex]\left \{ {{y=x+4} \atop {y=-x+2}} \right.[/tex]
The solution of the given system of equations comes to be x=-1 and y=3.
So they will intersect at (-1,3)

Answer:
x =12
Step-by-step explanation:
We use the Pythagorean theorem
a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse
x^2 + 5^2 = 13^2
x^2 +25 =169
Subtract 25 from each side
x^2 +25-25=169-25
x^2 = 144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x = 12

0.7
Step-by-step explanation:
If you divide 10 by 13 you get 0.76923 which rounded to the nearest tenth is 0.7
Hope this helped!
Answer:
0.8
Step-by-step explanation:
To find the decimal form of [tex]\frac{10}{13}[/tex] you'll need to divide 10 by 13.
10 ÷ 13 = 0.76923076923
The tenths decimal place is one to the right of the decimal: 0.1
Because the number after the tenths place is greater than or equal to 5, we will round the 0.7 up to a 0.8
Given: m arc AB = 4x, m arc BC = 3x
m arc CD = 2x, m arc DA = 3x
Find: m∠APB
Answer:
a > m/bp
Step-by-step explanation:
flip the equation
abp > m
divide both sides with bp
abp/bp > m/bp
a > m/bp
Answer:
m<APB = 30 degrees
Step-by-step explanation:
The sum of angles in a circle is 360 degrees. Add up all the arcs to get the equation : 4x+3x+2x+3x=360 degrees.
x is equal to 30 degrees
m arc AB = 4x = 120 degrees
m arc DC = 2x = 60 degrees
By secants exterior angles, m<APB = 1/2(m arc AB - m arc DC) = 1/2(120-60) = 30 degrees.
The answer is m<APB = 30 degrees

What is Maya’s biking speed?
PLZ HELP IN A BIG RUSH PLZ PLZ PLZ
Answer:
Maya's biking speed is 8 miles per hour.
Step-by-step explanation:
She can run 18 miles in 3 hours. That means she could run 6 miles in one hour. So, if she can ride her bike 18 miles in 2 hours she can bike 9 miles per hour.
If she bikes for 27 (3 hours) miles and runs 9 miles (1.5 hours) then taking the total of miles dividing it by the time you would get Maya's speed.

Answer:
The measure of the hypotenuse is 25.
Step-by-step explanation:
To solve, we can use the Pythagorean theorem a² + b² = c² where,
a = 7
b = 24
(7)² + (24)² = 625
We have to take the square root of 625 to get our answer.
[tex]\sqrt{625} = 25[/tex]
Answer:
25
Step-by-step explanation:
This is a right triangle. This is because of the little square in the corner that indicates a right angle. Therefore, we can use the Pythagorean Theorem.
a^2+b^2=c^2
where a and b are the legs, and c is the hypotenuse.
We know that 7 and 24 are the legs, because they make up the right angle. We know c is the hypotenuse because it is opposite the right angle.
7^2+24^2=c^2
Evaluate the exponents on the left side.
49+576=c^2
Add 49 and 576
625=c^2
Since c is being squared, take the square root of both sides. This will cancel out the exponent, and leave c by itself.
√625= √c^2
√625=c
25=c
The measure of the hypotenuse is 25

The diameter of a circle measures 8 cm. What is the circumference of the circle?
Use 3.14 for it, and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
16π or 50.266
Step-by-step explanation:
Circumference formula is just 2πr ,and the radius is 8, so just sub into the formula
Answer: 25.12 cm
Step-by-step explanation:
The formula for the circumference of a circle is [tex]2\pi r[/tex], when r = the radius.
Diameter = 2 x radius = 8 cm. Therefore, the radius = 4 cm.
Plug r = 4 cm in to the circumference formula: [tex]2\pi (4)[/tex] = 8 x 3.14 = 25.12 cm.
