Answer:
B. 3x -2y = 10
Step-by-step explanation:
The given line rises three units for each two units of run to the right. Hence its slope is 3/2. A parallel line will also have a slope of 3/2.
Of the equations we can see, selection B has a slope of 3/2. It can be rewritten in slope-intercept form as ...
3x -10 = 2y . . . . . add 2y-10 to isolate the y-term; next divide by 2.
y = 3/2x -5 . . . . . the coefficient of x is the slope
Answer:
y=25.5
Step-by-step explanation:
To find y, you need to get it by itself. Ask yourself, what is being done to y, then to undo that, do the opposite. For example, if 3 was added to y, you would need to subtract 3 to cancel out the 3. In this case, what is being done to y? It's being divided by 3. So, you multiply by 3 to cancel that out. Whatever you do to one side of an equation, you also have to do to the other. So,
8.5=
Multiply both sides by 3
3(8.5) = 3() multiply on the left side, and on the right side the 3s cancel out
25.5=y
The answer is a because if you do the math right the it will come up at 4, 9 which means that state a double as much as B
Answer:
<u>F</u>
Step-by-step explanation:
Evaluating the expression :
4 is clearly a rational number.
Hence, the right option is <u>F</u>.
Answer:
C. The same number of guests attended Rick and Tom's party.
Step-by-step explanation:
Let R and T represent the number of guests at Rick's and Tom's parties, respectively. The charges Rick and Tom paid are equal, so we have ...
65 +25R = 40+25+25T
25R = 25T . . . . . . . . . . . . subtract 65
R = T . . . . . . . . . . . . . . . . . divide by 25
The number of guests at each party is the same.
