Answer:
y≤5
Step-by-step explanation:
3 ≥ y - 2
Add 2 to both sides
3 (+2) ≥ y - 2 (+2)
5 ≥ y
or
y ≤ 5
Hope this helps!
S would be equal to 10. We’d multiply 45 by 2 to get the 90 then divide by 9 to isolate it
Answer:
Part 1) The price of a USB memory, stick selling at a 21% discount of its market price (m) ------> 0.79m
Part 2) The price or a CD that sells for 21% more than the amount (m) needed to manufacture the CD -----> 1.21m
Part 3) The final value of a painting after its initial value m, increases by 2/5 -----> 
Part 4) The total number of markers that Nancy has if she gives away 2/5 of her m markers to Amy ----->
Step-by-step explanation:
Part 1) The price of a USB memory, stick selling at a 21% discount of its market price (m)
we know that
100% is the market price m
100%-21%=79%
79%=79/100=0.79
so
The price of a USB memory with a 21% discount of its market price is equal to multiply m by 0.79
(0.79)*m=0.79m
Part 2) The price or a CD that sells for 21% more than the amount (m) needed to manufacture the CD
we know that
100% is the amount m
100%+21%=121%
121%=121/100=1.21
so
The price or a CD that sells for 21% more than the amount (m) is equal to multiply m by 1.21
(1.21)*(m)=1.21m
Part 3) The final value of a painting after its initial value m, increases by 2/5
we know that
100% is the initial value m
2/5=0.40=40%
100%+40%=140%
140%=140/100=1.4
Convert to fraction
1.4=14/10=7/5
so
The final value is equal to m multiplied by 7/5
Part 4) The total number of markers that Nancy has if she gives away 2/5 of her m markers to Amy
we know that
100% is the number of makers m
2/5=0.40=40%
100%-40%=60%
60%=60/100=0.6
Convert to fraction
0.6=6/10=3/5
The total number of markers that Nancy has is equal to multiply m by 3/5
so
A) Variables:
X = number of weeks she puts money into the account.
Y = total amount in account after x weeks.
B) m would be the amount she puts in per week, b is the starting amount she has in the account
Y = 5x + 40
C) replace x with the x values in the cart and solve for y:
O : y = 40. Coordinates (0,40)
1: Y = 45. (1,45)
2: 50, (2,50)
3: 55, (3,55)
4: 60, (4,60)
D) make the graph using the above points
E) y intercept is when x is 0, which is 40. This was the starting value of how much money was saved.
You would cross multiply for this.
20 ·
35 = 700
Then you would divide.
700 ÷
50 = 14
There would be
14 cones placed along 35 feet of road.
