Answer:
13
Step-by-step explanation:
104×7=728
728÷56=13
Answer:
x=60
Step-by-step explanation:
3/5x + 1/4x=51
12/20x+5/20x=51
17/20x=51
17x=1020
x=60
Double-Check:
3/5(60)+1/4(60)=51
180/5+60/4=51
36+15=51
51=51
Hope it helped!
Answer:
2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3.
Step-by-step explanation
Similarly, if we divide the numerator and denominator of 12/18 by 6 we get. 12/18 = 12÷6 / 18÷6 = 2/3. So 12/18 is an equivalent fraction of 2/3 as well.
Answer:
13
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean Theorem
where<em> a</em> and <em>b</em> are the legs and <em>c</em> is the hypotenuse.
We know that the legs are 5 and 12. We also know the hypotenuse is x, or unknown.
Substitute 5 in for <em>a</em>, 12 for <em>b, </em>and x for <em>c.</em>
<em /><em />
Evaluate the exponents.
5^2 is the same as 5*5, which is 25.
12^2 is the same as 12*12, which is 144.
Add 25 and 144
We are trying to find out what <em>x</em> is. In order to do this, we have to get <em>x</em> alone. Since x is being squared, take the square root of both sides. The exponent and square root will cancel, leaving x by itself.
The hypotenuse is 13.
