Ryan earns $5 for each small dog he walks and $8 for each large dog he walks. Today he walked 8 dogs and made a total of $49. How many small dogs did Ryan walk?
Ryan walked
small dogs.
Answer:
small dogs= 5
large dogs= 3
Step-by-step explanation:
Step one:
given data
let the number of small dogs be x
and the number of large dogs be y
Ryan earns $5 for each small dog he walks and $8 for each large dog he walks.
He walked 8 dogs and made a total of $49
so
5x+8y=49----------1
x+y=8---------------2
x=8-y
5(8-y)+8y=49
40-5y+8y=49
collect like terms
3y= 49-40
3y=9
divide both sides by 3
y=9/3
y=3
put y= 3 in eqn 2
x+3=8
x=8-3
x=5
Solve for x and find the measure of

— 3 + 5 + 6g = 11 – 3g
Given : −3 + 5 + 6g = 11 − 3g
To find : The variable g
Solution:
Isolate and solve for the variable g in the equation −3 + 5 + 6g = 11 − 3g
Steps:
−3 + 5 + 6g = 11 − 3g
2 + 6g = 11 − 3g
6g = −3g + 9
9g = 9
g = 1
Hence,
Answer: g = 1

if rounded to nearest integer, it is 10. if to 3 decimal places or 4 significant figures, it is 9.980
which one is correct????
Given:
[tex]m\angle ABC=46^\circ[/tex]
BD bisects angle ABC.
To find:
The [tex]m\angle ABD[/tex].
Solution:
It is given that, BD bisects angle ABC. It means, BD divides the angle ABC is two equal parts. So,
[tex]m\angle ABD=m\angle DBC=\dfrac{\angle ABC}{2}[/tex]
We need to find [tex]m\angle ABD[/tex], so
[tex]m\angle ABD=\dfrac{\angle ABC}{2}[/tex]
[tex]m\angle ABD=\dfrac{46^\circ}{2}[/tex]
[tex]m\angle ABD=23^\circ[/tex]
Therefore, the [tex]m\angle ABD[/tex] is 23°. Hence first option is correct.
X^9/7 convert from exponent form to radical form
Answer:
[tex]x^{\frac{9}{7}} = \sqrt[7]{x^9}[/tex]
Step-by-step explanation:
You can solve this by realising that the denominator of a fractional exponent can be expressed as the base of a radical.
Note also that the order does not matter. You could also express it as
[tex]\sqrt[7]{x}^9[/tex]
The reason this works is that you're effectively breaking the exponent into fractions. The first answer is the equivalent of:
[tex](x^9)^{1/7}[/tex]
and the second would be:
[tex](x^{1/7})^9[/tex]
In both cases, the exponents would be multiplied, giving the same result.

Solve x4 - 11x2 + 18 = 0.
Answer:
x=√2, x=-√2, x= 3 and x=-3
Step-by-step explanation:
We need to solve the equation x^4 - 11x^2+18=0
We can replace x^4 = u^2 and x^2 = u
So, the equation will become
u^2 -11u+18 = 0
Factorizing the above equation:
u^2 -9u-2u+18 =0
u(u-9)-2(u-9)=0
(u-2)(u-9)=0
u=2, u=9
As, u = x^2, Putting back the value:
x^2 =2 , x^2 =9
taking square roots:
√x^2 =√2 ,√x^2=√9
x=±√2 , x = ±3
so, x=√2, x=-√2, x= 3 and x=-3
Answer:
The second answer is correct.

Find an equation of the line having the given slope and containing the given point.
m= -6, (5,9)
The equation of the line is y =
(Simplify your answer. Type your answer in slope-intercept form. Use integers or fractions for any numbers in the expression.)
Answer:
[tex]y = -6x + 39[/tex]
Step-by-step explanation:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept(value of x when y = 0).
We have that the slope is m = -6:
So [tex]y = -6x + b[/tex]
Contains point (5,9):
This means that when [tex]x = 5, y = 9[/tex]. We replace this into the equation to find b. So
[tex]y = -6x + b[/tex]
[tex]9 = -6(5) + b[/tex]
[tex]b = 39[/tex]
So
[tex]y = -6x + 39[/tex]

If f(x)= x/2-2 and g(x)= 2x^2+x-3, find (f+g)(x).
Answer:
2x^{2} + \frac{3}{2} x - 5
Step-by-step explanation:
(f+g)(x) = f(x)+g(x)
(f+g)(x)= [tex]\frac{x}{2} -2[/tex] + [tex]2x^{2} +x-3[/tex] = [tex]2x^{2} + \frac{3}{2} x - 5[/tex]
Freddie has a bag of jelly beans that has the following colours. 2 purple 1 red 4 yellow 3 orange. What is the probability that Freddie will select an orange jelly bean?\ 10% 20% 30% 40%
100 point
Answer:
30%
Step-by-step explanation:
3 out of the ten beans are orange
3/10=30%
Answer:
The answer is 30%.
Step-by-step explanation:
There are 2 purple, 1 red, 4 yellow, and 3 orange jelly beans. If you add all those together, you will get 10. So, 3 out of the 10 jelly beans are orange. That is 3/10 in fraction form. 3/10 equals to 30%, so that is your answer.
