Answer:number 3 is 22, 32 divided by two plus 6 is 22 therefore it would be 22
Step-by-step explanation:
Answer is 2/8 or 1/4
Explanation: 1 is the number for all of the students, 6/8 is the students not wearing blue shirts, so 1- 6/8 equals 2/8 which can be simplified to 1/4.
Answer:
x=11
BC=19
Step-by-step explanation:
AB+AC=AC this is because B is in between A and C. So now we can substitute all of the line segments, so we have
x+2x-3=30 Now you add 2x and x
3x-3=30 Now you add 3 to both sides so you can get 3x alone on one side
3x=33 Now you divide both sides by 3 so you get the x alone on one side
x=11
The next step is to substitute x to find BC.
BC=2x-3 Substitute the x with 11
BC=2(11)-3 Then multiply 2 and 11 because that is the rule with parenthesis
BC=22-3 then subrtact the 3 from 22
BC=19
You can check your work by doing AB+BC=AC
11+19=30 substitute your answers and then add them together
30=30
Subsitution method.
<span>
Y=3x - 11
</span><span>Y= -3x - 2
</span>
-3x - 2 = 3x - 11
+3x +3x
-2 = 6x - 11
+11 +11
6x = 9
x = 1.5
<span>Y=3(1.5) - 11
</span>y = 4.5 - 11
y = -6.5
Now we have our points.
Answer: x = 1.5 and y = -6.5
