Answer:
30
Step-by-step explanation:
1/2 x (a+b) x h = area
1/2 x ( 40 + x ) x 50 = 1750
1/2 (40 + x )= 1750/50
20 + 1/2x = 35
1/2 x = 35 - 20
x = 15 x 2
= 30
I hope this is right :)
Let's come up with variables to substitute and make an equation.
T = total number of minutes
P = number of minutes used by each person in the phone plan
R = remaining minutes per month
R=T-3P
Now that we have an equation, we can substitute the numbers we are given in the problem to find the final solution.
R= 675- 3(250)
R= 675- 750
R= -75 minutes
There are no remaining minutes, and in fact, the people on the phone plan have used 75 extra minutes than provided for in their phone plan.
Answer:
a = 14
Step-by-step explanation:
Because angles x and w are equal, sides 14 and a are also equal.
We can immediately conclude that a = 14.
Answer:
4/50 or 2/25
Step-by-step explanation:
Slope/rate of change is defined as the vertical distance over horizontal. then simplify.
Step-by-step explanation:
step 1. we must assume the ratio of flour to sugar is 2:1.
step 2. A = 2(3/4) = 3/2 1-1/2.
step 3. B = 1-3/4(1/2) = 7/4(1/2) = 7/8
step 4. C = 1(2) = 2
step 5. D = 2-1/2(1/2) = 5/2(1/2) = 5/4 = 1-1/4.
