Answer:
x=6
y=-3
Step-by-step explanation:
<em><u>solve for x-</u></em>
-4x+8y=-24 replace y with 0
-4x+8(0)=-24
-4x=-24 divide by -4 on both sides
x=6
<u><em>Solve for y-</em></u>
-4x+8y=-24 replace x with 0
-4(0)+8y=-24
8y=-24 divide by 8 from both sides
y=-3
The definition of supplementary is that the angles add to 180°. Hence, <em>c + d = 180; c + 45 = 180 </em>by substitution and finally ∡c = 135°.
No because it is 2 times the other angle so in that case one is bigger than the other
Answer: A. will
Step-by-step explanation:
Answer: 7 7/8 cups of flour
Step-by-step explanation:
Since John is making 3 1/2 batches of cookies and each batch takes 2 1/4 cups of flour.
The amount of flours that John will need for the cookies will be gotten by multiply the batches of cookies made by the number of flours of cups used per batch and this will be:
= 3 1/2 × 2 1/4
= 7/2 × 9/4
= 63/8
= 7 7/8 cups of flour
