Divide 7 3/4 by 24
You get 0.3095238095238095
Estimate the answer.
You get 0.34.
Answer:
126
Step-by-step explanation:
Row 1: 30+0*4
Row 2: 30+1*4
Row 3: 30+2*4
...
The list goes on. Do you see a pattern here? If we call the row number as r, the formula is 30+(r-1)*4. In the 25th row, the r is 25. So in the formula, it is 30+(25-1)*4=30+24*4=126.
I hope that helped.
Subtract 4 from -17, from 3x+4, and from 19:
-21 < 3x < 15
Divide all terms by 3:
-7 < x < 5 (solution)
Answer:
(3) 5(2x+11)
Step-by-step explanation:
Distribute the 5 into the parentheses and you should get 10x +55.
Answer:
See attached photo for graph
Step-by-step explanation:
Solve the equation for y... (that means get y by itself)
4y = -5x - 6 (subtract 5x from both sides)
y = -(5/4)x - 6/4 (divide both sides by 4)
y = -(5/4)x - 3/2 (simplify)
Now you can graph using slope-intercept method. The y-intercept is -3/2, and the slope is -5/4
