Answer: 20

Step-by-step explanation: In this problem, 15 is being represent as the part so we will have 15 over the part which we don't know which is going to be represented as 'x.' 75% is obviously the part which we will put over 100%.

Now, we can apply the cross products.

1500% = 75%x

X = 20

Can someone help me PLEASE

Arisa [49]

Let's solve this problem step-by-step:

$7 * 9 = (7*10)-(7*x)$

x: it is the delta in the equation given in your picture

We know (7*10) - (7*x) is equivalent to the 7*(10-x)

⇒ based on the Distributive Properties

$a*(b+c) = ab + ac$

$7*(10+(-x))=(7*10)+(7*(-x)=(7*10)-(7*x)$

So:

$7*9=7(10-x)\\9=10-x\\x=10-9\\x= 1$

Thus delta (the little triangle in this problem) in this case is 1

Answer: 1

Answer:

x=60

Step-by-step explanation:

(1/6)(x+6)=11

Multiply both sides by six:

(6)(1/6)(x+6)=11(6)

x+6=66

Take six from both sides:

x+6-6=66-6

x=60
