Step-by-step explanation:
Miss Lacey will have to pay more than $190 for the gym membership.
A product is the result of the multiplication, an expression that identifies factors to be multiplied.
Miss Lacey is paying $19 p.m for the gym membership fees. So she will have to pay for one year =19*12 because there are 12 months in a year.
=218
which is greater than $218.
Hence Miss Lacey will have to pay more than $190 for the gym membership fees.

Answer: more then 190
Step-by-step explanation:
if you multiply $19 by 12 (12 months in a year) you get $228
Answer: A roll of plain wrapping paper costs $17, while a roll of holiday wrapping paper costs $20.
Step-by-step explanation: First let us represent a roll of plain wrapping paper with letter p and a roll of holiday wrapping paper would be represented by d. If Eduardo sold 5 rolls of plain wrapping paper and 5 rolls of holiday wrapping paper for $185, then we can express this as
5p+ 5d= 185
Also if Sarawong sold 14 rolls of plain wrapping paper and 5 rolls of holiday wrapping paper for $338, then this too can be expressed as
14p + 5d = 338
Now we have a pair of simultaneous equations which are,
5p + 5d = 185 ———(1)
14p + 5d = 338 ———(2)
Since all the variables have coefficients greater than 1, we shall use the elimination method. Note that the coefficients of the d variable are both 5, so straight away we subtract equation (1) from equation (2) and we now have;
(14p - 5p) + (5d - 5d) = 338 - 185
9p = 153
Divide both sides of the equation by 9
p = 17
Having calculated p, we can now substitute for the value of p into equation (1)
5p + 5d = 185
5(17) + 5d = 185
85 + 5d = 185
Subtract 85 from both sides of the equation
5d = 100
Divide both sides of the equation by 5
d = 20
Hence, the cost per roll of plain wrapping paper is $17, while the cost per roll of holiday wrapping paper is $20.
Answer:
x=40 and y= 60
Step-by-step explanation:
step:1
Let 'x' and 'y' are two numbers
given data the sum of two numbers is 100
x+y = 100......(1)
Given difference of two numbers are
x - y = -20 ......(2)
Step :2
solving the equation (1) and (2)
adding the equations (1) and (2)
x+y+x-y=100-20
cancelling 'y' terms are
2 x = 80
dividing "2" on both sides, we get
x = 40
Step :3
substitute x = 40 in equation (1)
x + y =100
40 + y = 100
subtracting "40" on both sides, we get
40 + y - 40 = 100 -40
y = 60
Final answer:-
The two numbers are x = 40 and y= 60
