Answer:
Audrey can afford 4 hours of lesson.
Step-by-step explanation:
Given that:
Amount Audrey has to spend = $111
Cost of racket = $55
Cost per lesson = $14
Let,
y be the total cost
x be the number of hours
According to given statement;
y = 14x + 55
111 = 14x + 55
111 - 55 = 14x
14x = 56
Dividing both sides by 14
Hence,
Audrey can afford 4 hours of lesson.
Answer:
a) 17
b) 45
Step-by-step explanation:
a)
use pemdas first,
= 4
3x4 = 12
1x4 = 4
now the equation is
9+12 = 21
that makes the equation 21-4
21-4 = 17
a) 17
now for b
b)
the equation would then be
so youd use pemdas as always
start in the parenthases
= 4
4-1 = 3
the equation is now
now, multiply 3x3x4
3x3 = 9
9x4 = 36
now the equation is 9+36
9+36 is 45
b) 45
hope this helped!
