HOW CAN YOU MAKE 7,5,6,AND 3 EQUAL 75 USING PARENTHESIS.

Answers

Answer 1
Answer: (7+5)*6+3=12*6+3=72+3=\boxed{75}
Answer 2
Answer:

One possible answer is:

5((7x3)-6).

Explanation:

75 ends in 5, so it is divisible by 5. 75/5 = 15. If we can arrange 7, 6 and 3 some way to make 15, we can use this multiplied by 5.

7x3=21, and 21-6=15; this gives us what we need!

5(21-6) = 75; 21 = 3x7, so 5((3x7)-6).

Hi Brainiac


3x+2y=7

y=-3x+11


We need to solve y=-3x+11 for y

Now let's start by substitute -3x+11 for y in 3x+2y=7

3x+2y=7

3x+2(-3x+11)=7

-3x+22=7

Now add -22 to both sides

-3x+22-22=7-22

-3x=-15

To find the value for x we need to divide both sides by -3

-3x/-3= -15/-3

x=5

Now we have the value for x :)

Let's find the value for y by substitute 5 for x in y=-3x+11

y=-3x+11

y=-3(5)+11

y=-4

Here you go :)

The answer is D

What is the slope-intercept equation for the line below?

Answers

Answer: D

Step-by-step explanation:

If we look at the graph we can see that the line intercepts the y-axis at (0,-4), so the intercept must be -4.

If we use the rise-over-run formula for (0,-4) and (4,1) we would get:

(1--4)/(4) \n\n=(5)/(4)

Since the line is going upwards, the equation must be positive.

Therefore, the equation in slope-intercept form is y=5/4x-4.

Answer is D

First, we can eliminate option b and c because they are negative, and the line in the graph is goin up.
Then you count and get that the m is 5/4, put it together: y=5/4x-4
