I dont understand this!!! What's the answer?

Answers

Answer 1

Answer:

The answer is 1.

4x + 3x - 1 = 6

7x - 1 = 6 -Add the like terms

7x - 1 + 1 = 6 + 1 -Add 1 to both sides to 7x by itself

7x = 7

7x / 7 = 7 / 7 -Divide both sides by 7

x = 1

Hope I helped!

Answer 2

Answer:

To put this into words, the equation is saying that one less than 4x + 3x is equal to 6.

First simplify by combining like terms. We see there is a 4x and 3x, which means that they are compatible with each other. The equation will then look like $7x - 1 = 6$ . If one less than 7x is 6, then this can also mean one more than 6 is equal to 7x. So add 1 to both sides: $7x - (-1 + 1) = (6 + 1)$

--> $7x = 7$ , which means that x = 1.

Checking your work:

Now that we know the value of x, substitute that for x in the equation like this:

$4(1) + 3(1) - 1 = 6$

--> $4 + 3 - 1 = 6$

---> $7 - 1 = 6$

So you know it's true that x = 1. Hope this was helpful.

The graph below shows the relationship between the number of chores that Larissa completes and the amount of money that she earns. Which is the best prediction of the number of chores completed if she earns $5?
1
2
10
12

Answers

Answer:

Option B.

Step-by-step explanation:

The given graph represents the relationship between the number of chores, x that Larissa completes and the amount of money that she earns, y.

From the given graph it is clear that the equation of best fit line is

$y=2.09x+0.93$

We need to find the expected number of chores completed if she earns $5.

Substitute y=5 in the above equation and find the value of x.

$5=2.09x+0.93$

Subtract 0.93 from both sides.

$5-0.93=2.09x+0.93-0.93$

$4.07=2.09x$

Divide both sides by 2.09.

$(4.07)/(2.09)=x$

$1.947368421=x$

$x\approx 2$

Therefore, the correct option is B.

9 is 12 percent of what number? ( show your work)

Answers

For this question, we want to find out what 9 / 12 equals as a percentor x / 100. Therefore, we have a proportion here and can say:9/12 = x/100Now, at this point, we can cross multiply to get:900 = 12xNow, divide both sides by 12 to get x alone and find that:x = 75 <==== FINAL ANSWER
so 9 is 12% of 75!
I hope that helps you out! Please let me know if you have any other questions!
