Answer:
Error was at the fourth line: 12 = 16x
Correct solution: x = ½
Step-by-step explanation:
Let's solve the equation step by step to find the correct solution, and also, to find out at which line Cam made a mistake.
10 - 2x = 19x + 2 - 5x (given)
10 - 2x = 19x - 5x + 2
10 - 2x = 14x + 2
Add 2x to both sides
10 - 2x + 2x = 14x + 2 + 2x
10 = 14x + 2x + 2
10 = 16x + 2
Subtract 2 from both sides
10 - 2 = 16x + 2 - 2
8 = 16x (this is where Cam made an error, at the fourth line. He wrote: 12 = 16x. It seems Can only subtracted 2 from the right, then added 2 to the left. Subtraction property of equality was not properly done.)
Proceeding further with our calculation, we would divide both sides by 16
8/16 = 16x/16
½ = x
x = ½.
V = (4/3)π*r^3
.. = (4/3)*3.14*(5.3 ft)^3
.. = 623.3 ft^3
Answer:
Blue Line: y = 4x - 1
Green Line: y = -x + 6
Red Line: y = -x
Step-by-step explanation:
Looking at the equation y = mx + b
- The first giveaway is that the green line is the highest y-intercept (b- value). So we can say it's y = -x + 6
- Second giveaway is that the blue line has the lowest y-intercept (again the b- value). So we can say it's y = 4x - 1
- Third giveaway is that the red line has the same x-intercept AND y-intercept which is y = -x. Both intercepts are (0, 0).
Lastly, the rest of the statements are true in correspondence of the last 3 statements.
Answer:
Surface area is, 478 square centimeter
Step-by-step explanation:
Surface area (S)of rectangle is given by:
.....[1]
where,
l is the length
w is the width
h is the height of the rectangle respectively.
As per the statement:
A rectangular solid has sides of 7 cm, 9 cm, and 11 cm
⇒ l = 7 cm , w = 9 cm and h = 11 cm
Substitute in [1] we have;
⇒
Therefore, the surface area is, 478 square centimeter
(4x - 1)(3x + 5)
Try different combinations of the front number's factors with combinations of the last number's factors. The FOIL until you find one that works.
