So first of all the question is asking you to convert feet to inches
Answer: A. x= 5"
Step-by-step explanation:
ORIGINAL/NEW = 11"/7" = 8.5"/x
x = 7" x 8.5"/11" = 59.5"/11 = 5.409 ≅ 5.41"
If we wanted to keep most of the engraving, we would adjust the larger dimension, but we have been asked to adjust one dimension to 5", since it is said that C. x = 5.41 is incorrect
Then we will adjust
ORIGINAL/NEW = 11"/y = 8.5"/5"
y= 11" x 5"/8.5" = 6.47"
Then the new dimensions of the paper are 6.47" x 5" to fit an 7" x 5" frame
Answer: A. x= 5"
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
Step-by-step explanation:
2^3=8
3^3=27
4^3=64
so if you add all the positive integer cubes it will be 8+27+64=99
hence 99 is less than 100
Hence solved.
