30 Points and will mark brainliest: Bruce has $1200 in the bank. He wants to Save a total of $3000 by depositing $40 per week from his paycheck. Write and use an equation to find how many weeks he needs to reach his goal.

A - 1200x + 40 = 3000; x=45 weeks

B - 1200 + 40x = 3000; x = 45 weeks

C - x(1200 + 40) = 3000; x = 45 weeks

D - x(1200 - 40) = 3000; x = 45 weeks

Answer:

a) Yes agree

and b) (I'm not too sure about this one but I think..) By CPCT that is Corresponding parts of congruent triangles are equal/congruent theorem.

Step-by-step explanation:

I'll use this " [ " symbol for angle.

a) yes agreed ;

AB = CB (B is the midpoint of AC)

[ ABD = [ CBD = 90°

BD = BD (common side)

--> therefore by SAS criteria triangle ABD is congruent to triangle CBD.

and by CPCT .... AD = CD .

b) AD = CD (proven by CPCT)

...answer for b you're likely suppose to write it that way. so yeah hope this helps.

Answer:

the correct selling price is $10

And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price

Step-by-step explanation:

The computation is shown below:

Given that

Markup = 25%

Cost of an item = $8

Selling price of an item = $2

Based on the above information

The amount of markup would be

= 25% × 8%

= $2

Now amount after markup is

= $2 + $8

= $10

Hence, the correct selling price is $10

And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price

Answer:

part A:The correct selling price is $10

Part B:And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price

Answer:

28

Step-by-step explanation:

what you do is add 39 plus 74

that answer will give you 113 so then you subtract 180 from that

then you get 67, then what you do is subtract 39 and you would get 28

x = 28

9514 1404 393

Answer:

  1. multiply both sides by 3

  2. (a) chose to multiply by 2/3 instead of 3/2; (b) did the multiplications incorrectly, both for the fraction and the integer; (c) x = 9

Step-by-step explanation:

1. If you want to "clear fractions," you multiply by the denominator of the fraction.

  3(2/3)x = 3(6)

  2x = 18

__

2. The coefficient of x is 2/3. If you want it to be 1, you need to multiply by the multiplicative inverse of 2/3, which is 3/2. Doing that gives ...

  (3/2)(2/3)x = (3/2)6

Then simplifying gives ...

  x = 18/2 = 9

__

Trey's mistakes were: a) choosing the wrong multiplier; b) carrying out the multiplication incorrectly. (2/3)(2/3) = 4/9, and 6(2/3) = 4. Had Trey done the multiplications correctly, he would have seen that he needed a different multiplier to get to the answer.

Answer:

The length is 28 and the width is 11

Step-by-step explanation:

To solve this problem, we can make the width as x.

Since the length is 5 less than 3 times the width, it's going to be 3x - 5

So now we've got the length and width, just need to find the perimeter, which is all the sides added up together. They already gave us the perimeter, so we just have to solve the equation:

2(3x - 5) + 2x = 78

6x - 10 + 2x = 78

8x - 10 = 78

8x = 88

x = 11

x = 11, but remember, x is the width, not the length. Since we already found what x is, we just have to plug it into the equation of:

3x - 5

3 × 11 - 5

33 - 5 = 28

Answer: Length = 28 (don't forget to add the unit if there is one)

Answer:

17

Step-by-step explanation:

Answer:

Let's solve your equation step-by-step.

3x+2=14

Step 1: Subtract 2 from both sides.

3x+2−2=14−2

3x=12

Step 2: Divide both sides by 3.

3x /3 = 12/3

x=4

Answer:

option 2 is the best answer

Step-by-step explanation:

I actually couldn't tell you 100% how i got this answer, but i narrowed it down to option 2 and option 3 because those ones have the inequality sign facing the correct way, and then I solved the inequalities to see which one made more sense, and option 3 came out as negative and you can't have a negative cost on something, so option 2 is the best answer.
