Answer:
Step-by-step explanation:
2x11=22
3(3+x)
22=9x+3x
Subtract nine
13=3x
Multiply 13 by 3=13/3
Convert to decimal
Answer is:4.3
Answer: C, because I’m assuming you meant 84°.
Explanation: 2+6+7 is equal to 15. The three angles of a triangle will always add up to 180, so you need to divide 180 by 15, which is 12. Then, multiply each number (2, 6, and 7) by 12 to get your answer, which is 24, 72, and 84 :)
Answer:
A=3.5
B=4.5
C=9.5
Step-by-step explanation:
You can solve A and C with the last two equations through trial and error
then you plug in the solved A into the first equation to solve for B
Answer:
Step-by-step explanation:
if point (x,y) is rotated 90 degrees, x becomes y and y becomes -x
for point (x,y) rotated 90 degrees it will become (y,-x)
Rational numbers are sometimes natural numbers. For example, the number 1 is both a rational and natural number. Remember that natural numbers are 1, 2, 3, 4.. etc. Rational numbers are any number that can be expressed as a ratio of 2 integers. 1/1 is rational.
Most rational numbers, however, are not natural. For example, 3/4, 89/88, and so on.
