The first picture would be choice answer c because the number of x's represent how many birds wings are this size. The number on the tic mark represents the size of the wing span. So you would take the number of x's times the tic mark represented under it. There are 3 birds with 3 1/8 wingspan so it wold be 3 1/8 *3. Hoped this helps for the first one!
Answer:
128 my answer needs to be long so im just gonna span a little
If you divide 311 by 500 you would get 0.622 as your decimal
Answer:2
Step-by-step explanation:
Answer: =−20
y=2
Step-by-step explanation:
Solve for xx in -5y-10=x−5y−10=x.
x=-5y-10
x=−5y−10
2 Substitute x=-5y-10x=−5y−10 into x+9y=-2x+9y=−2.
4y-10=-2
4y−10=−2
3 Solve for yy in 4y-10=-24y−10=−2.
y=2
y=2
4 Substitute y=2y=2 into x=-5y-10x=−5y−10.
x=-20
x=−20
5 Therefore,
\begin{aligned}&x=-20\\&y=2\end{aligned}
x=−20
y=2
