Answer:
0.6
Step-by-step explanation:
Given the trapezoid formula:
1/2(b1+b2/2)xH
We are given the numbers for the trapezoid:
0.3,0.9,1
To solve this here is what we are going to do.
1/2(0.9+0.3)x1
So add 0.9+0.3=1.2
Then Divide 1.2/2=0.6
So multiply 0.6 x 1=0.6
0.6 is your answer
57-8=49
So then 7y=49
Y=1 so 2y=2
Answer:
3y - 5 + 2y = 7
Step-by-step explanation:
Subtracting 5 from the second equation gives ...
x = 3y -5
Using the expression on the right for x in the first equation gives ...
x + 2y = 7 . . . . . . . . first equation
(3y -5) +2y = 7 . . . . with expression substituted for x
3y - 5 + 2y = 7 . . . . with parentheses removed
