What he's saying is that 7/8 of his ties + 4 ties = all of his ties.
7/8x + 4 = x
Thus, 4 is 1/8 of his ties.
4 = 1/8x
So you simply multiply 4 by 8 to get 32 ties.
32 = x
To check, plug 32 back into the original equation:
7/8(32) + 4 = (32)
28 + 4 = 32
It works!
Hope that helps.
Answer:
Step-by-step explanation:
It is given that AC:CM = 3:4.
Therefore, let AC = 3k and CM = 4k
It is given that Δ ACM is right angled.
Therefore,
AM = 5k
But, AM = MP + AP
Therefore, MP + AP = 5k --- (1)
It is given that MP - AP = 1 --- (2)
Multiply (1) and (2), we get.
(MP + AP)(MP - AP) = 5k × 1 = 5k
Add and subtract on the left side.
--- (3)
But, since CP ⊥ AM, Δ CMP and Δ CAP are right triangles. Therefore,
and
Now, (3) becomes,
7k = 5 or
AM = 5k
Answer:
all fractions containing integers are rational numbers is true I believe.

Answer:
B
Step-by-step explanation:
It isn't A. A has to be something like y = -x^2 That minus sign directs the parabola downward.
It could be B which is something like y = x^3 - 5
C has an odd number of real roots (5). In other words it crosses the x axis 5 times. So let's make one of these up and graph it
y = (x^2 - 4)(x^2 - 1)(x + 3) Study this for a minute. The leading coefficient of this polynomial is plus 1. There are no negatives in front of the x. The highest degree is x^5. Now here's the key question: on the left side where does the graph start? In Quad three right? It's coming from the lower left. That is exactly what graph C is NOT doing. So for C the graph has a leading coefficient that is less than 0. a<0
Not C.
D is not the answer either. It opens downward and looks like it is something like y = - x^4 + 3x^3 - 2x^2 + 5x - 2
