Answer:
3+18=21
Step-by-step explanation:
first see the second number
let us assume as x & y
3+ (3×6)= 21
3+18=21
830$ there are 52 weeks in a year. 52 times 15 is 780. 780 plus 50 is 830
Answer:
135 + 100h = 535
Step-by-step explanation:
to solve it would be 535-135= 400
then 400/100=4
135h + 100 = 535 no
135 - 100h = 535 no
135 + 100h =535 yes
135 + 100 = 535 no
For the one that is correct it would go like this
So h is the amount of hours which we do know but want to check
135 + 100h = 535
-135 -135
100h = 400
/100 /100
h = 4
And h is hours which we also got 4
so it would be 135 + 100h = 535
The answer is C.
To solve these types of equations you first need to make sure that you equation is equal to 0. In this case all of the numbers are already on the same side so no work needs to be done there. Then we can get a, b and c values for the quadratic equation by looking at the coefficients.
a = 4 (number attached to x^2)
b = -6 (number attached to x)
c = 1 (number with no variable attached)
Now we can put this into the quadratic equation.
