Answer: 47.5
Step by step:
5x+y (x=9)(y=2.5)
5(9)+2.5
45+2.5
= 47.5
In vertex form the value of the vertex is easily identified in the equation. I’m standard form the value of the x intercepts are evident.
Answer: 60% = 60/100 = 60 ÷ 100 = 0.6. 100% = 100/100 = 100 ÷ 100 = 1.
Step-by-step explanation: Decrease number by 60% of its value. Percentage decrease = 60% × 150 New value = 150
Answer:
x = 929/126
Step-by-step explanation:
12/19(x-22)=38-6x-3
Combine like terms
12/19(x-22)=35-6x
Multiply each side by 19
19* 12/19(x-22)=19*(35-6x)
12( x-22) = 19*(35-6x)
Distribute
12x - 264 = 665 - 114x
Add 114x to each side
12x +114x - 264 = 665 - 114x+114x
126x -264 = 665
Add 264 to each side
126x-264+264 = 665+264
126x = 929
Divide each side by 126
126x/126 = 929/126
x = 929/126
