Answer:
x = 11, y = 17
Step-by-step explanation:
Note that
9x - 4 = 8x + 7 ( vertical angles )
Subtract 8x from both sides
x - 4 = 7 ( add 4 to both sides )
x = 11
and
7y - 34 = 5y ( vertical angles )
Subtract 5y from both sides )
2y - 34 = 0 ( add 34 to both sides )
2y = 34 ( divide both sides by 2 )
y = 17
J = 106% . x
S = 106% . (550+x)
O = 106% . 2x
S = 2(212+O) = 106%(550+x)
S = 424 + 2O = 583 + 106%x
2(106%.2x) - 106%x = 583-424
159 = 106%x( 4 - 1 )
159 = 106%x ( 3 )
159 = 318%x
1 = 318%x : 159
1 = 2%x
1 = 2/100 . x
x = 50
Jivesh put $50
Stacy put $600
Oliver put $100
Answer:
B
Step-by-step explanation:
you want to know the total cost for 4 people. You know that it costs $5.75 for one person, you would multiply that cost by 4. So the equation will look like this.
4 x $5.75 = x
Let's call the number of pages that Jen wrote "j".
then tom (t) wrote:
What we know:
j=10t
this means:
t=0.1 j
and j+t=396
for this it's practical to substitute j with 10 t:
10t+t=396
11t=396
we divide both sides by 11:
t=36
so tom wrote 36 pages, and Jen wrote ten times as much, or 360 pages (that's a lot!)
