Answer:
Plan A is a salary of $360 per month, plus a commission of 8% of sales. Plan B is a salary of $740 per month, plus a commission of 3% of sales.
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
4x+9=-3x+2
=> 7x=-7 move all x to left side and numbers to right side by changing + to - or - to +
x=-1
Okay. So, we're looking for the percentage of Celina's running speed as her walking speed. Her running sped is 8 mph and her walking speed is 4mph. All we have to do is 4/8 = x/100. You put change/original and x/100, because we're looking for the percent of change from running speed to walking speed. Cross multiply the values to get 400 = 8x. Divide each side by 8 to isolate the "x". 400/8 is 50. x = 50. Celina's walking speed is 50% of her running speed. The answer is B: 50%.

Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Summing the 3 angles and equating to 180 gives
2x + 3 + 4x + 2 + 2x - 1 = 180
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22
∠A = 2x + 3 = (2 × 22) + 3 = 44 + 3 = 47°
∠B = 4x + 2 = (4 × 22) + 2 = 88 + 2 = 90°
∠C = 2x - 1 = (2 × 22) - 1 = 44 - 1 = 43°
