Answer:
- 4
Step-by-step explanation:
(2*(Rationalize(9.7)-Rationalize(4.8x)))==Rationalize(61.2)-Rationalize(3.4)
Rationalize(18.4)-Rationalize(2.8x)
==Rationalize(57.8)
-Rationalize(2.8x)==Rationalize(57.8)-Rationalize(18.4)
x= 38.4÷-2.8
:x= -4
Answer:
x = 4.
Step-by-step explanation:
We see that it passes through the x axis at the point (4, 0) so x = 4 is a solution.
Check by solving the equation
x^2 - 4x + 13 = 13
Subtract 13 from both sides:
x^2 - 4x = 0
x(x - 4) = 0
x = 0 or x - 4 = 0, so:
x = 0 or 4.
Answer:
Step-by-step explanation:
1) Rewrite the words into an equation:
÷ 4
2) Change the division sign to a multiplication sign and find the reciprocal of 4 (flip the numerator and denominator of 4):
3) Change the mixed number into an improper fraction:
4) Multiply:
Answer:
(I think) it's 10 cms because total perimeter is 30 centimeters so there will be 5 on two sides making 10,30-10=20 and 20/2=10 which makes a total of 30 (5+5+10+10)
Answer:
55
Step-by-step explanation:
20-9 = 11 then 5x11=55
