Step-by-step explanation:
area= 1/2 (base1+base²) h
A = {1/2 (5+12)} × 4
A = {1/2 (17)} × 4
A = 8.5×4
A = 34
I think this is right
I hope this helps you
y= -15 x= -20
y=12 x=?
?.-15=12.-20
?=12.20/15
?=16
x=16
Answer:
Step-by-step explanation:
y=mx+c
So in this case, m is (-3/7), which is the slope.
(-3/7)(another slope)=-1
Another slope=3/7
A. The slope is -7/3
B. The slope is 3/7
C. The slope is -7/3
D. The slope is -3/7
Thus, the answer is the bottom of the left hand side, which is 3x-7y=14
Hope it helps!!! Good luck!!
Answer:

Step-by-step explanation:

The question seems to be pointing towards a multiple choice response but I will do my best. The first equation would be 15x+12y=9.30 and the second would be 10x+4y=4.60, x represents flour and y represents sugar.
Hope this helps.
