How do i put this into words please help
Serjik [45]
Hello,

This is simple :)

<span>First divide:

How many times does 16 go into 7? : 0

7 GOES into 16, 0 times, now we have ; 0.

Next, multiply 16(0):0

Now, subtract 7-0

=7

Bring 0 down... so now we have 70... how many times can you divide 16 into 70? : about 4 times.

Now we have: 0.4

Multiple 16 by 4

= 64 : SUBTRACT 64 from 70

=60

Bring Down: 0; this gives us 60.

Divide:

How many times can 16 go into 60? : About 7 times

No we have : 0.437..

Bring down 0; gives us 600: how many times can 16 go into 600?: About 5 times.

Now, we have 0.4375.


Thus, 7/16 = 0.4375.


Faith xoxo

How do u do question 25. How do u find the measure of X?
ser-zykov [4K]
Recall that a circle has a total of 360°, now the arc that is NOT part of "x", is 250°, therefore the leftover, namely the arc made where "x" is at, has to be 360° - 250<span>°, that's the degree measure of that arc.

now, arc's get their angle measure from the central angle they're in, in this case, "x" is the central angle, and therefore, it has the same measure of 360</span>° - 250°.

Ab= 10
Ad= 2Ab+8
Perimeter of parallelogram is 2(a+b)
So 2(2ab+8)+2(ab)=6ab+16
6ab+16=76
6ab=60
Ab=10
