Answer:
5/hypotenuse, the square root of 7/ leg
Step-by-step explanation:
3^2+4^2=25 or 5^2. you use a^2+b^2=c^2. it would be one of the hypotenuses. If the missing number is a leg, you would do 4^2=3^2+x^2. 16=9+x^2, 7=x^2, so you plug in the numbers differently.
Answer:
4.2
Step-by-step explanation:
10% of 42 is 4.2
Step-by-step explanation:
9x - 2 = 5x + 54 because these angles are corresponding
9x - 5x = 54 + 2 add/subtract like terms
4x = 56 and this divided by 4
x = 14
9x - 2 + 10y + 6 = 180° because these two angles makes a straight line
9×14 - 2 + 10y + 6 = 180°
126 - 2 + 10y + 6 = 180° add like terms
130 + 10y = 180° subtract 130 from both sides
10y = 50 divide by 10
y = 10
Answer:
3x=total amount of money, 3x
Step-by-step explanation:
Because the number of notes books is the same (x and x), you can simply add them.
Basically, the equation is 1x+2x= total cost but you can add 1x and 2x because they have the same variable
The solution of given inequality is: 
<em><u>Solution:</u></em>
<em><u>Given inequality is:</u></em>
We have to find the value of "x"
<em><u>Let us solve the given inequality</u></em>
Divide both sides of inequality by 7
<em><u>Simplify the above expression</u></em>
Thus the value of x is
