Step-by-step explanation:
Shopping...
there is a sale on a shirt for 1/3 off, but the shirt costs 5 dollars. You would then need to convert the fraction to a decimal to find the percentage you would get off of the original price.
Ok so first you need to put w and x in the equation —-> 13-0.5(10)+6(1/2) and now you just solve -0.5 times 10 is -5 so 13-(-5)+6(1/2) now multiply 6 times 1/2 which is 3 so now we have 13-(-5)+3= 21
Answer:
The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
x + y = 24
3x + 5y = 100
Try elimination.
-3x - 3y = - 72
2y = 28
y = 14
Then x = 10
So, we have 10 3-point problems and 14 5-point problems.
Answer:
Let x represent number of calling minutes
Step-by-step explanation:
17 + .11x = 22 + .07x
.04x = 5
x = 5/.04 = 125 minutes, is the number of minutes the two plans cost the same
17 + .11*125 = $30.75 is the cost when the two plans cost the same
