Answer:
1. 5 is a solution to the inequality
2. 8 is a solution to the inequality
3. q=20 is a possible solution to the inequality
4. t=28 is not a possible solution to the inequality
Step-by-step explanation:
1.
1+f<7
subtract 1 from both sides of the inequality;
f<7-1
f<6
The value of f should therefore be strictly less than 6. From the alternatives given only the number 5 meets this condition and is thus a solution to the inequality.
2.
g-3>4
add 3 to both sides of the inequality;
g>4+3
g>7
The value of g should therefore be strictly greater than 7. From the alternatives given only the number 8 meets this condition and is thus a solution to the inequality.
3.
q-2>16
add 2 to both sides of the inequality;
q>16+2
q>18
The value of q should therefore be strictly greater than 18. Consequently, q=20 is a solution to the inequality since;
20>18
4.
t-7<10
add 7 to both sides of the inequality;
t<10+7
t<17
The value of t should therefore be strictly less than 17. Consequently, t=28 is not a solution to the inequality since;
28 is not less than 17.
Answer:
the answer is 5 here you go
-3x+4y=-18
2x-y=7
the answer qould be C.(2,-3)
-3(2)+4(-3)=-18
-6+(-12)=-18
-18=-18
2(2)-(-3)=7
4+3=7
7=7
C.
5/8 = 0.625
6 / 9.6 = 0.625
12.8 * 0.625 = 8
x = 8
6x + 52 > 130
Subtract 52 from both sides:
6x > 78
Divide both sides by 6:
X > 78/6
X > 13
