BIG JIM/LITTLE JIM PROBLEM When Big Jim stands on a bench that is 15 inches high, the top of his head is 53 inches above the top of Little Jim’s head. Big Jim’s height is twice that of Little Jim’s height. How tall is Big Jim? How tall is Little Jim?
Answers
Answer:
Let J = height of Little Jim. Then Big Jim's height is 2J.
when big jim stands on a bench that is 15 inches high, the top of his head is 53 inches above the top of little jims head.
The above given sentence means 15+ 2J= J+53.
15+2J = J+53
2J-J = 53-15

(( Ignore the first answer, I didnt mean to put true-)
Answers
Answer:
1) False
2) True
3) True
4) False
Step-by-step explanation:
For the first statement, we can look at a graph with the line of y = 3.69x plotted. If we check the points (7.38, 2) and (11.07,3), they do not intersect with the line. So, the first statement is false.
For the second statement, we can check the equation for the line to find the slope. The equation, y = 3.69x, is in slope-intercept form, or [tex]y = mx + b[/tex]. In this form, [tex]m[/tex] is the slope of the line. [tex]b[/tex] is the y-intercept. In this line, there is no y-intercept specified, so we can take this to mean the y-intercept is 0. The slope, we can see, is 3.69. The slope, multiplied by x, shows us any point of the line. The second statement, then, is true.
The next statement can be verified by finding just how much 16 gallons will cost. Like we've seen before, the slope can be multiplied by x, the number of gallons, to see where that point will be plotted. So, we can multiply the slope by 16.
3.69 · 16 = 59.04
The (x) value, we already know, is 16. The (y) value, we've found, is 59.04. So 16 gallons will be plotted at (16, 59.04). The third statement is true.
The last statement says that if the price increases by $0.05, the slope will be 3.64. We can tell this is false by adding 0.05 to the original slope, 3.69.
3.69 + 0.05 = 3.74
3.74 ≠ 3.64, so the last statement is false.
I hope this was helpful to you ^^

Answer:
40 cm³
Step-by-step explanation:
The information we have about the volume of Prism Y is only that it is 10 cm³ greater than the volume of Prism X. So, we have to first find the volume of Prism X.
The volume of a rectangular prism is found by multiplying the length, width, and height of the figure. X has dimensions of 2 × 5 × 3, so we will multiply these together.
2 · 5 · 3 = 30
The volume of prism X is 30cm³.
Prism Y is 10 cm³ greater than this.
30 + 10 = 40
Prism Y has a volume of 40 cm³.

Solve for y: 5(y + 2/5) = -13
Answers
Hope this help
Answer:
y = -3
Step-by-step explanation:
Let's solve your equation step-by-step.
5 (y+2/5) = −13
Step 1: Simplify both sides of the equation.
5(y+2/5)= −13
(5)(y) + (5)(2/5) = −13(Distribute)
5y + 2 = −13
Step 2: Subtract 2 from both sides.
5y + 2 − 2 = −13 −2
5y = −15
Step 3: Divide both sides by 5.
5y/5 = −15/5
y = −3
Answer:
y = −3

Solve the system of equations
the equations.
Answers
Answer:
y = 9.54
and, x = 0.08
Step-by-step explanation:
Given that
x - 2y = -19 .......................(1)
3x + 5y = 48 ...............(2)
Based on the above information
Multiply by 3 in equation 1
So,
3x - 6y = -57
3x + 5y = 48
- - -
-11y = -105
y = 9.54
So, the x would be
x - 2(9.54) = -19
x - 19.08 = -19
x = -19 + 19.08
x = 0.08
