Answer:
y = -2
x = 5
Step-by-step explanation:
3x - y = 17
-x + y = -7
here we can find the sum of the two equations
2x = 10
x = 5
now we can just plug in the value of x to find y
-(5) + y = -7
y = -2
Answer:
A^2+B^2=C^2
Step-by-step explanation:
12=a
16=b
this is the pythagoreon theorem
Answer:
Answer is 25/56
Step-by-step explanation:
Given that
Katie and her brother are both writing a report. Katie write 7/8 of her report and her brother wrote 3/7 of his report
TO compare these two fractions we have to make both of them have the same denominator.
We find that as such the two fractions have denominators as 7 and 8 and hence Least common multiple is 56
LEt us make equivalent fractions
7/8 = 49/56
3/7=24/56
Difference i.e. Katie wrote more than her brother = 49/56-24/56
=25/56
1-First let’s list the numbers between 210 to 220, except the even ones since they’re a multiple of 2:
211; 213; 215; 217; 219
Let’s remove 213, and 219 because they’re multiples of 3 (2+1+3=6; 2+1+9=12), 215 is multiple of 5, so let’s remove it.
That leave’s is with 211, and 217.
We can remove 217, because it’s a multiple of 7, leaving us with 211.
2- It’s deductive reasoning, because you started with a more general idea.
3- {-7, -6, -5, -4, -3, -2, -1, 0, 1}
4- {x e R, x>=-2}
5-{-1, 0, 1}
6- {x∣-4≤ x ≤6}
7- [-20, ♾ )
8- On a number line, make a circle around -1, and continue the line to minus infinity.
9- On a number line, make a circle on -3, and continue to minus infinity. Make a ring on 0, and continue to infinity.
