1 answer:
Answer:
First equation solution:
x≤4
Second equation solution:
x≥4
Step-by-step explanation:
1/2x+8≤ 10
subtract 8 from each side
1/2x≤ 2
multiply each side by 2
x≤ 4
-3x-24≤- 36
add 24 to each side
-3x≤ -12
divide by -3 ( when dividing or multiplying by a negative number the </>/≤/≥ flips)
x≥4

Take the absolute value of the difference, then divide it by the original amount |28 - 24.5| / 28 = 3.5/28 = 0.125..now we multiply that by 100 to get it into a percent 0.125 * 100 = 12.5% <== ur answer
Answer:
x=20
Step-by-step explanation:
inverse operation
add 7 to both sides
x=20
325 - [4(58 - 19) + (75 / 3)] Divide: 325 - [4(58 - 19) + 25] Distribute 4: 325 - [232 - 76 + 25] Subtract: 325 - [156 + 25] Add: 325 - [181] Subtract: 144
Answer:
3x + 5y = 11 -> y = -3/5x + 11/5
9x + 15y = 33 -> y = -3/5x + 11/5
