Let the two number be x and y.
x+y=-1......i
2x+4y=-10.....ii
solving the simultaneous equation we have:
from equation i, making x the subject we get:
x=-1-y........iii
substituting iii in ii we get:
2(-1-y)+4y=-10
-2-2y+4y=-10
2y=-10+2
2y=-8
y=-8/2=-4
substituting the value of y in iii we get:
x=-1-(-4)
x=-1+4
x=3
therefore the first number is 3 and the second number is -4
Answer:
12*x^18
Step-by-step explanation:
144=(2^4)*(3^2)
then
sqrt (144 x^36)=sqrt (144)*sqrt (x^36)
sqrt (144)=sqrt ((2^4)*(3^2))=2² * 3=12
sqrt (x^36) =x^(36/2)=x^18
therefore
sqrt (144 x^36)=sqrt (144)*sqrt (x^36)=12*x^18
the answer is 12*x^18
It's an isosceles triangle, so the angles at the base are congruent:
The triangle XYW is a rectangular triangle.
We know that the sum of the measures of angles in a triangle is 180°.
Therefore we have the equation:
Answer: 73
3 were called on Friday.
Then the each of the 3 called 3 others which all equals to 9, since 3*3 is 9.
Now, each of the 9 called 3 others on Sunday which altogether equals 27, since 9*3 is 27. Therefore, the answer is 27.
Every time the word each is used in a math problem, that would mean that you need to multiply something. And that's what happened here
