Answer:
1.19
Step-by-step explanation:
You're trying to figure out what x is here.
So you'll want to isolate the x. That means, get it alone.
Since both sides are equivalent, when you subtract 2.45 from the x side, you also subtract it from the other side too.
x = 3.64 - 2.45
x = 1.19
Answer:
42/50, 21/25
Step-by-step explanation:
84/100=42/50=21/25
The answer is 11.2
The Pythagorean Theorem says
a^2+b^2=c^2
From the picture, we know one side, and the hypotenuse.
10^2+b^2=15^2
100+b^2=225
b^2=225
Sqrtb^2=sqrt225
b=11.18
Rounded to the nearest tenth it is 11.2
