James used substitution to solve this system of equations. Which could be the result of his first step
2x+3y=12
y=x+1.5
A..y=2x+3y+1.5
B.2x+3(x+1.5)=12
C.2x+3x+1.5=12
D.y=2x+3y

Answers

Answer 1
the answer would be B. :)
Answer 2
B, it's B because the system gives you what Y equals and so you need to substitute (x+1.5) for the y in your equation. From there solve to get- 2x+3x+4.5=12. From here you will want to add like terms, 2x+3x= 5x. Your new equation should look like this- 5x+4.5=12. From here solve for x.

How to find the slope using the rising over run and the slope formula

Answers

X/y?

So I’m assuming x divided by y will give you your slope

Answer: Divide the rise by the run to calculate the slope, which helps you to find the rise and run between other points on the same line. In the example, x divided by y calculates a slope of x/y . A positive slope means the line goes up from left to right, but a negative slope means it goes down.

Step-by-step explanation:

Answer:thats easy lol 8x12=area so its 96

Step-by-step explanation:

Suppose Carson worked as a babysitter for '8' hours one week. What is the minimum number of full hours he would need to work at his fathers business to earn at least $96 that week?

Answers

Answer:

The minimum number of full hours did Carson need to work at his father's business is 8 hours and 15 minutes  

Step-by-step explanation:

Given as :

The total number of hours did Carson spent as baby sitting on one week = 5 hours

The rate at which he earn for baby sitting = $6 per hours

The rate at which he earn as job = $8 per hours

The total amount he will earn that week = $96

Let The minimum number of full hour he need to work = h

Now, According to question

The total amount he will earn that week = total number of hours did Carson spent as baby sitting on one week ×The rate at which he earn for baby sitting  + The rate at which he earn as job × The minimum number of full hour he need to work

I.e $96 = $6 × 5 + $8 × h

Or, $96 = $30 + $8 × h

Or, 8 × h = 96 - 30

Or, 8 × h = 66

∴  h =  

i.e h = 8.25 hours

So, The number of hours = h = 8 hours and 15 minutes

Hence,The minimum number of full hours did Carson need to work at his father's business is 8 hours and 15 minutes  .

8 hours 15 minutes that week

A scale model of a boat is 6 inches long. The actual boat is 42 feet long. Which statement(s) are true??

Answers

Answer:

B. 1 in = 7 ft

Step-by-step explanation:

Since on the scale the boat was 6 inches and the actual boat was 42 feet, we need to divide to see how many feet correlate to the number on inches on the scale. So we do 42 / 6, which equals 7. This means that for every inch on the scale, it will be 7 feet in real life.

the answer is B. hope this helps

Step-by-step explanation:

Ok, so in 5th grade, we were taught to use PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction), to get a long question correct. It has to be in that order, so start with parentheses. Here is the whole equation simplified: 8+1465+7380-2938. Now you will go from left to right. So, you have 1473+4442. And last, simplify, 1473+4442=5915. Hopefully this helped and if it did please mark it brainliest.
