10 x 10 = 100
100 x 5 = 500
10 x 10 x 10 = 1,000
1,000 x 4 = 4,000
4,000 + 500 = 4,500
Hope this helped!
7 is digit for hundred thousands and 6 is for ten thousands so the answer is 800,000
5x+8=-27
8 more means addition. -27 would be total. 5 times the number ( in this case x) would mean multiplication.
3/8 because there are 3 numbers you want to land on and 8 total numbers.
Answer:
13 months
Step-by-step explanation:
x is the number of months
first phone:
f(x) = 55x + 100
second phone:
g(x) = 51x + 150
now set up the inequality
g(x)<f(x)
51x + 150 < 55x + 100
Solve the inequality:
51x + 150 < 55x + 100
(get everything on the correct sides... combine the like terms)
51x - 55x < 100 - 150
-4x < -50
divide both sides by -4 (don't forget to flip the inequality sign when dividing by a negative number.)
x > 50/4
x > 12.5
round up to 13
