Answer:
A=2.5
B=2
Step-by-step explanation:
A parallelogram has to have the opposite sides equal each other. In this case side LM and side ON have to be equal.
We can compare the two sides using algebra.
4b+7=8b-1
Using simple methods, we can isolate b on a single side.
1+7=8b-4b
8=4b
b=2
From this we learn b is 2. To find out the value of A on side MN and LO, we will plug in the value for b at all instances of B in this equation.
2a = 2b+1
2a = 2(2)+1
2a=4+1
2a=5
a=2.5
Answer:
I Believe the answer is 38.48
Step-by-step explanation:
How I got this answer by using the formula (A = π × r2)
so you would plug in π x 3.5^2 (because it's your radius) and square to get the answer of 38.48451001, if you round it would be 38.48
Answer:
23
Step-by-step explanation:
Let the three number be represented by x, y and z. We can rewrite them as follows:
x = x
y = x + 2 <em>(because its two jumps to the next odd number)</em>
z = y +2 = x + 4
x + y + z = 75
∴ x + (x+2) + (x+4) = 75
∴ 3x + 6 = 75
∴ 3x = 69
∴ x = 23
∴ x=23, y=25, x=27.
The smallest number, x, is equal to 23.
2560-1944= 616gallons
7 days in a week or 14 days in two weeks
616gallons / 14days = 44 gallons / 1 day
Notice in the fraction we have
(Gallons / days)
Now if you filled the take up the entire way
2560 gallons
We have gallons and the question wants the amount of days
Thus to cancel gallons we set the equation up as such
(2560 gallons) x (1 day / 44 gallons) = 58.18 days
Or 58 days
