Please, enclose those binomials x+4 and y+7 inside parentheses:
(x+4) / 4 = (y+7) / 7. Find (x/4).
Let's solve the above equation for x:
x+4 = 4(y+7)/7. Then x = 4(y+7) / 7 - 4
Last, divide all 3 terms by 4: x/4 = (y+7) / 7 - 1 (answer)
y + 7 - 7
You could also type this as x/4 = ------------- = y/7

Answer:
x=1,-5x=1,−5
Step-by-step explanation:
0=(x−1)(x+5)
2 Switch sides.
(x-1)(x+5)=0(x−1)(x+5)=0
3 Solve for xx.
x=1,-5x=1,−5
If Connor edits 34 pages in 8 hours. Using the equivalent ratios, the table has been completed.
The equivalent ratios are the ratios that has same value when we compare them. We can check two or more ratios and check whether they are equivalent or not.
Connor edits 34 pages in 8 hours
Number of pages he edits in 8 hours = 34 pages
Number of pages he edits in 1 hour = 34/8 = 17/4 pages
Number of pages he edits in 12 hours = (17/4)×12
= 51 pages
Complete the table
Hence, if Connor edits 34 pages in 8 hours, using the equivalent ratios, the table has been completed

Answer:
30y+14
Step-by-step explanation:
add the values of all the sides together: (5y+4) + (5y+4) + (10y+3) + (10y+3) = (5y + 5y + 10y + 10y) + (4 + 4 + 3 + 3)= 30y + 14
