Answer:
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
Step-by-step explanation:
Let
x -----> number of pages that Polina read
y ----> number of pages that Marcus read
we know that
x+y=108 ----> equation A
x=5y -----> equation B
substitute equation B in equation A and solve for y
Find the value of x
therefore
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
Answer:
The area is 6(m-2) I don't know how to explain but it's obvious. You don't want the rest of the unshaded area
Answer:
Overall percentage is 125% than you can - 15% which = 110%
10 % = 2700 as this is the profit. 2700 x 10 = 100% = Rs 270,000
X/5 + 3 = 2
x+15=10
x=-5
Ans : A
y=total amount of money
x=# of toppings
At JOES PIZZA
Large cheese- $0.25 per topping + base fee of $10
equation- y=0.25x+10
At SAMS PIZZA
Large Cheese- $0.50 per topping + base fee of $8
equation- y=0.5x+8
SYSTEM OF EQUATIONS
y=0.25x+10
y=0.5x+8
lets try 8 toppings first
y=0.25(8)+10
y=2+10
y=12
y=0.5(8)+10
y=4+10
y=14
8 does not work
lets try 1.5 topppings next
y=0.25(1.5)+10
y=0.375+10
y=10.375
y=0.5(1.5)+8
y=0.75+8
y=8.75
1.5 does not work
lets try 4 toppings next
y=0.25(4)+10
y=1+10
y=11
y=0.5(4)+8
y=2+8
y=10
4 does not work
finally 12 must work
y=0.25(12)+8
y=3+8
y=11
y=0.5(12)+8
y=6+8
y=14
we got y=11 for the first equation with 12 toppings y=11 for the first equation with 4 toppings
12+4=18
12 toppings at joes and 4 at sams i believe
