Eliminate p terms
times 2nd equation by -1
q-2p=-5
add to 2nd equation
q-2p=-5
<u>7q+2p=29 +</u>
8q+0p=24
8q=24
divide both sides by 8
q=3
sub back
2p-q=5
2p-3=5
add 3
2p=8
divide by 2
p=4
p=4
q=3
Answer: what is the rest of the question?
Step-by-step explanation:
Easy peasy
sub random points for x and solve for y
or solve for y and sum points for x and get y values
some easy points that work most of the time
sup
x=0
y=0
if x=0
0-4y=-18
4y=18
y=9/2
y=4.5
(0,4.5) is one point
if y=0
x-4(0)=-18
x=-18
(-18,0) is aonther
another is
(-5,2)
3 points are
(0,4.5)
(-18,0)
(-5,2)
Answer:
Step-by-step explanation:
If triangle ABC is dilated to form triangle DEF
If we want to prove triangle ABC is similar to Triangle DEF then two Pairs of corresponding angles are required
If two pairs of angles are corresponding then third pair should be corresponding as well.
<span>So we want to know the number from which we take 65% and get 39. If the number we are looking for is x, then the equation to find that x would be: (65/100)*x=39 which says sixty five percent out of x is equal 39. So, x=(39*100)/65. And finally, x= 3900/65=60. So, 65% out of 60 is 39.</span>
