Answer:
The answer in the procedure
Step-by-step explanation:
we have
2x-3y=-1 ----> equation A
3x+3y=26 --> equation B
Solve the system by elimination
Adds equation A and equation B
2x-3y=-1
3x+3y=26
----------------
2x+3x=-1+26
5x=25
x=25/5
x=5
Find the value of y
substitute the value of x in equation A or equation B and solve for y
2(5)-3y=-1
10-3y=-1
3y=10+1
y=11/3
Answer:
x = 11
Step-by-step explanation:
-3x + 4 = -29
step one : subtract 4 from both sides
-3x = -29 - 4
-3x=-33
step two : divide -3 from both sides
-33 ÷ -3 = 11
x = 11
check your work now
-3(11) + 4 = -29
-3 x 11 = -33
-33 + 4 = -29
Answer:
60m^2
Step-by-step explanation:
Ok so if you subtract the 18 by 12 then divide by two you get the missing lengths of each of te triangles. If you then use the area of a trapezoid formula (think about it like pulling one triangle off one side and putting it next to the other to make a rectangle) you just do L x W and get 60.
Answer:
8(x/2) + 8(3/8) = 1(8)
8(x/2)..the two cancels out and you are left with 4x
8(3/8)..the 8 cancels and leaves with 3
1(8)=8
4x+3=8
Subtract the 3 from both sides to get the x term alone
4x=5
Divide both sides by x to get alone
x=5/4
