Answer:

step-by-step:

since 33 has a minus sign before it, first suntract that number from the large number (82), then also subtract the sum (35) giving you 14 which has to be the last number. check you work by putting the number in the empty slot and making sure it works.

Emily tried solving a two step equation for the variable. Interpret whether she made a mistake or not. If she did, describe what

Daniel [21]

-1 = z/3 - 7

Emily's Work:

-1 = z/3 - 7

-1(3)=z/3(3)-7

-3 = z - 7

-3 -7 = z - 7

z = -10

Right away without having to start at the beginning, I see that she has made a mistake at the 4th-5th line of work.

Instead of adding 7 to both sides, she subtracts it and still leaves it in and doesn't fully finish the equation, as it would really be z-7 = -10

In order to solve it, follow these steps:

Rewrite the initial equation as follows:

x/3 - 7 = -1

Multiply both sides by 3
x/3(3)-7(3)=-1(3)

x - 21 = -3

Add 21 to both sides

x = 18

$\implies {\blue {\boxed {\boxed {\purple {\sf {d. \: - 84}}}}}}$

$\sf \bf {\boxed {\mathbb {Step-by-step\:explanation:}}}$

✒ $\: 6\:a\:b$

Plugging in the value "a = 7" and "b = -2" in the above expression, we have

Find the x and y intercepts.

Roman55 [17]

-3/4x + 5/6 y = 15

Multiply through by 6

-9/2x + 5y = 90

Add 9/2x to both sides

5y = 90 + 9/2x

Divide both sides by 5

y = 18 + 9/10x

y = 9/10x + 18
Comparing with the general equation of a straight line y = mx + c

Gradient (m) = 9/10 or 0.9
and the y - intercept (c) = 18

4/5 minus 1/3 plz i need help

IRISSAK [1]

Answer:

7/15

Step-by-step explanation:

Step 1

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 4 by 3, and get 12.

Then we multiply 1 by 5, and get 5.

Next we give both terms new denominators -- 5 × 3 = 15.

So now our fractions look like this:

−

Step 2

Since our denominators match, we can subtract the numerators.

12 − 5 = 7

So the answer is:

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

Nope! So now we try the next greatest prime number, 11...

No good. 11 is larger than 7. So we're done reducing.
