The amount of money in dollars that Rob owe his father is -$18

Answer:y=9.5x-0.5

Step-by-step explanation:

Ok, so you need to use the equation y2-y1/x2-x1 to find the slope. So (18.5-4.25)/(2-0.5) so 14.25/1.5 , calculate that and you get 9.5 which is your slope, apply that to the slope formula which is y=mx+b where (m) is slope and (b) is y intercept and you get y=9.5x-0.5

Answer:

X = 3+y

X = 2y - 4

Step-by-step explanation:

The system of equations for the given situation will be written as X = 3+y and X = 2y - 4.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Adam is three years older than Joe. After three years, Adam's age will be four years less than two times Joe's age. Considering Adam's present age as x years and Joe's present age as y years.

The equation can be written as,

X = 3+y

X = 2y - 4

just did a test on edge and got a 100%

Answer:

15% increase

Step-by-step explanation:

In order to solve this problem begin with finding the difference between the initial value and final value. [tex]46-40=6[/tex] then once this value is known divide it by the original value to get a decimal. [tex]\frac{6}{40}[/tex] which gives you [tex]0.15[/tex] multiplying this value by 100% will give you your answer. [tex].15 * 100 =[/tex][tex]15[/tex]%  

TLDR: the answer is 15%

Answer:

Step-by-step explanation:

Given the perimeter of the rectangular shape = 170m

Length of the diagonal = 130m

Perimeter = 2L + 2W

diagonal d² = L² + w²

L is the length of the terrain

w is the width

140 = 2L + 2W

70 = L+W ..... 1

130² = L²+w² ..... 2

from 1, L = 70-w

substitute into 2;

130² = (70-w)²+w²

130² = 4900-140w + 2w²

16900 = 4900-140w + 2w²

2w²-140w - 12000 = 0

w²-70w - 6000 = 0

On factorizing;

(w+50)(w−120) = 0

w - 120 = 0

w = 120 m

Since L = 70 - w

L = 70 - 120

L = -50m

Hence the dimension is 120m by 50 m

Answer:

60$ is the normal price.

Why:

Because if 45$ is 75%, then 30$ is 50%, 15 is 25%, and 0 is 0%. 50% + 50% = 100%. (That's how I did this one, anyway. This works on any 25%, 50%, or 75% problem.)

Answer:

No

Step-by-step explanation:

Think of the decimal number as 97. Would it round up or down? Because 7 is greater than 4, you would round it up to 100. And since this is a whole number, the correct answer would be 7 meters per second.

Hope this makes sense!

Answer:

300 minutes

Step-by-step explanation:

Given

10 feet in 40 minutes

Required

Determine the time to shovel 75 feet

Let the required be represented with x

First, we need to represent the given and required as ratios.

[tex]Given = 10 : 40[/tex]

[tex]Required = 75 : x[/tex]

Since you work at steady rate, then both ratios are equivalent.

[tex]10 : 40 = 75 : x[/tex]

Convert to fractions

[tex]\frac{10}{40} = \frac{75}{x}[/tex]

[tex]\frac{1}{4} = \frac{75}{x}[/tex]

Solve forx

[tex]x * 1 = 75 * 4[/tex]

[tex]x = 300[/tex]

Answer:

y = 4x - 5

Step-by-step explanation:

move the 2y to the left side of the equation and move the 0 to the right side of the equation in which it becomes -2y = -8x+ 10 then divide the whole equation by -2 since y cannot be negative and have a coefficient. so then the equation becomes y = 4x - 5.

Answer:

Emily can buy 6 movie tickets after paying the admission fee

Step-by-step explanation:

Let x be the number of movie tickets

If each movie ticket costs 5 dollars then the cost of x movies will be 5x

And the admission fee will be a constant.

She has $40 in total

So the equation can be written as

[tex]10+5x = 40\\5x = 40-10\\5x = 30\\\frac{5x}{5} = \frac{30}{5}\\x = 6[/tex]

Hence,
