-60 is negative so the 2 facotrs are different signs
11 is positive so therefor te positive factor is bigger than negative
list all factors and add and find which add to 11
60-1=59 nope
30-2=28 nope
20-3=17 nope
15-4=11 yep
factors are 15 and -4
Answer:
4/6=8/12
Step-by-step explanation:
If the denominator is multiplied by 2, the numerator needs to do the same to keep the fraction equal.
6*2=12
4*2=8
4/6=8/12
Answer:
z=-13/7
Step-by-step explanation:
1. Add 3z(7z+5=-8)
2. Subtract 5(7z=-13)
3. Divide 7(z=-13/7)
First setup the system of equations for the given case.
Let sandwich=x
and delivery fee =y
Equations are:
4x+y=33 Equation 1
8x+y=61 Equation 2
Subtract equation 1 from 2.
4x=28
x=7
Now substitute value of x in equation 1.
4(7)+y=33
28+y=33
y=5
So cost of single sandwich=$7 and Delivery fee=$5
Now cost of 12 sandwiches:
12x+y=85
Put y=5
12x+5=85
12x=80
x=6.67 which is less than 7. So, They are not able to get 12 sandwiches for $85.
