Answer:
2/21
Step-by-step explanation:
2/21 is the answer...........that is the fraction......
x+1/3=3/7
x=3/7-1/3
LCM=21
x=9/21-7/21
x=2/21
Answer:
Step-by-step explanation:
SV = RV
2x+2 = 10
x = 4
r² = RV² + VZ² = 10²+7.5² = 156.25
UZ = √[r²- (QR/2)²] = √[156.25 - 10²] = √56.25 = 7.5
Answer:
yes correct
Step-by-step explanation:
given
5x ≥ 3x + 4 ( subtract 3x from both sides )
2x ≥ 4 ( divide both sides by 2 )
x ≥ 2 ← is the solution to the inequality
The only value greater than 2 is 3
Answer:
One
Step-by-step explanation:
It is given that,
y = 3x-5 ....(1)
y = -x+4 .....(2)
We can solve the above equations using substitution method. Put the value of y from equation (1) to equation (2) such that,
Put the value of x in equation (1) we get :
It means that the value of x is 
and the value of y is 
. Hence, the given equations has only one solution.
2x2+2x-1=
4+2(-3)-1=
4+(-6)-1=
4+(-7)=
-3
