Answer:
340 phones
Step-by-step explanation:
Make an expression
She repairs 10 phones each day, d.
Each day she repairs 10 phones, it is 10 phones off the total number (450) she has to repair, so we can subtract 10d from 450.
450-10d
We want to find how many she has left after 11 days, so we can substitute 11 in for d
450-10(11)
Multiply
450-110
340
She will still have 340 phones left to repair

Answer:
4
Step-by-step explanation:
So you just plug in the X value of the number that d represents for example if I plug in 2 for d
7(2)^2+10=38
100 cm = 1 meter
<span>4.5 meter x 100 cm = 450 cm </span>
<span>450 cm / 4.5 cm = number of pieces of ribbon </span>
<span>450/4.5 = 100</span>
