Find the missing value for X

1 answer:

7 0

If we assume that BC is bisecting AD, and that AE is half of AD, we can set up the equation:

$2(19)=5x-7$

Then we can solve directly for x:

$38=5x-7$
$45=5x$
$x=9$

So we have then calculated x which is equal to 9.

Answer:

a. $\frac{70}{100}$

b. 0.7

c. 0.7=70%= $\frac{70}{100}$

Step-by-step explanation:

70% of 100 received an A, that is 70/100 times 100 equal to 70

$\frac{70}{100}*100=70$

a. 70% = $\frac{70}{100}$

b. $\frac{70}{100}$ = 0.7

Notice that 70/100 is equal to 7/10 which is 0.7

c. 0.7=70%= $\frac{70}{100}$
