Answer:
The value of x would be 5
Step-by-step explanation:
(for future reference if you have questions like this it’s better to fill in numbers for x to be able to answer the question)
So you want to fill in x with a number. In this case in order for this equation to be right you fill x with 5.
So 5(5)+10=35
And to check your answer to make sure it’s right you would add the measure of angle R which is 55 to the measure of angle M which is 35.
55+35 is 90. Which makes your answer for x correct :) hopefully this makes sense.
Let the number of sodas sold be x and the number of hotdogs sold be y. We can assemble a system of equations from the information given and solve.
x+y=170 (We know that soda + dogs is 170)
x-50=y (We know that dogs is equal to 50 less than sodas)
We can use substitution to solve this system of equations.
x+y=170
Sub in the value of y from the second equation
x+(x-50)=170
2x-50=170
2x=220
x=110
We now know the number of sodas sold was 110. Lets now plug this value into the equation to solve for y.
x+y=170
110+y=170
y=60
So, there were 60 hotdogs sold and 110 sodas sold.
Answer:
44
Step-by-step explanation-
Jack has 6 less than 5 times what mark has, if we write it out, we have (5*mark)-6. We know that mark has 10, so if we replace it we have
(5*10)-6 we get 50-6 which equals 44
Answer
Find out how much money did she start with.
To proof
let us assume that the money she had be x.
As given
woman spent two thirds of her money
Money she had after spent two thirds of her money = Total money - money spent
As given she lost two thirds the remainder
we get
Money she had after lost two thirds the remainder = Money she had after spent two thirds of her money - she lost two thirds the remainder
As given
she had $4 left
thus
x = $36
she start with $36.
Hence proved
Answer:
3/20, -3/10
Step-by-step explanation:
Its a quadratic equation, use the quadratic formula. (-b+-
)/2a
20x^2+3x-2=0
(-3+-
)/40
(-3+-9)/40
So you get 6/40=3/20 and -12/40=-3/10
