Answer:
B
Step-by-step explanation:
Given
5x + y = 14 ( subtract 5x from both sides )
y = 14 - 5x
Substituting values of x into the right side allows the corresponding value of y to be found.
x = - 1 : y = 14 - 5( - 1) = 14 + 5 = 19
x = 0 : y = 14 - 5(0) = 14 - 0 = 14
x = 1 : y = 14 - 5(1) = 14 - 5 = 9
Hence the corresponding values of x and y are
x y
- 1 19
0 14
1 9

Answer:
£18.06
Step-by-step explanation:
The computation of her pay per hour is shown below:
= Total earnings last year ÷ Total number of hours she worked
= £27,000 ÷ (32.5 hours × 46 weeks)
= £27,000 ÷ 1,495 hours
= £18.06
Answer:
c = 160 - 3(45)
Step-by-step explanation:
if c = the number of characters left;
160 = maximum number of characters that can be used in a text
3*45 = number of characters in sentences already used. (There are 3 sentences of 45 characters.)
(# of char left) = (max # char) - (# char already used) so:
c = 160 - 3*(45)
c = 160 - 135
c = 25
