Answer:
[tex]a = \frac{1}{2} [/tex]
[tex]b = 0[/tex]
Step-by-step explanation:
[tex]a - b = \frac{1}{2} \\ a + b = \frac{1}{2} \\ \\ a - b + a + b = \frac{1}{2} + \frac{1}{2} \\ a + a = \frac{2}{2} \\ 2a = 1 \\ \frac{2a}{2} = \frac{1}{2} \\ a = \frac{1}{2} [/tex]
[tex]a + b = \frac{1}{2} \\ \frac{1}{2} + b = \frac{1}{2} \\ b = \frac{1}{2} - \frac{1}{2} \\ b = 0[/tex]

Maya can run 18 miles in 3 hours, and she can bike 18 miles in 2 hours.
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

Function A is represented by the equation
y=1/3x+5. Function B is represented by the graph. Which function has a greater rate of change? explain.
Answer:
They have the same rate of change.
Step-by-step explanation:
Well the graph of Function B is y = 1 / 3x + 2
So they have the same rate of change, since they have the same slope.
10 over 13 as a decimal rounded to the nearest tenth
Answer:
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

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.

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

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

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)
