Answer:
i think the answer would be 21 dollars for 5.75 x 3.6.
5.00 x 3.6 equals to 17.96
all together about 38.96 or 40
Step-by-step explanation:
Answer:
J
Step-by-step explanation:
Step 1: solve for y
Step 2: graph y, use dashed line
Step 3: Shade in solutions, here y>3 so everything bigger then 3 is a solution.
Using the elimination method, multiply the first equation by 60 and the second one by 30 (least common denominators)
30x-45y=11...(1)
12x+5y=9...(12)
Multiply the second equation by 9, to eliminate y
30x-45y=11
+ 108x+45y=81
———————-
138x=92
x=92/138 (reduce fraction with 46)
x=2/3
Substitute x=2/3 into equation 2
12(2/3x)+5y=9
y=1/5
Therefore, the solution to the system is C. (2/3, 1,5)
Answer:
x=4
Step-by-step explanation:
2(8 - 12x) + 8x = -25x + 52
Distribute
16 -24x +8x = -25x +52
Combine like terms
16 - 16x = -25x +52
Add 25x to each side
16 -16x+25x = -25x+52+25x
16+9x = 52
Subtract 16 from each side
16+9x-16 = 52-16
9x = 36
Divide by 9
9x/9 = 36/9
x =4
Answer:
1 golf ball : $2.50
Step-by-step explanation:
- You can first divide 6 and 15 by 3, and get 2 and 5.
- Then, you divide 5 by 2, which is 2.5
- Therefore, the unit rate is 1 golf ball : $2.50
