Combining like terms with negative coefficients -3x-6+(-1)

Mathematics
1 answer:
Verdich [7]3 years ago
6 0

Step-by-step explanation:

Hey there!!

You can simply do it.

Here, -3x -6 +(-1) is given.

In this question, the like term is "-6" and "-1" because both are coefficients.

Combine it.

= -3x -6 -1 { as (-) (+)=(-)}

= -3x -7 { when there is (-) sign then it will be added but the sign would be minus}.

Or you can also write it as -( 3x+7). {taking (-) common}

If an angle measuring 20 is bisected to form two new angles, what is the measure of each new angle
alexgriva [62]

Answer:

10 degrees

Step-by-step explanation:

Bisection means dividing into two equal parts

So, if we bisect an angle measuring 20 degrees

It will divide into 2 equal parts and:

=> 20/2 = 10 degrees

Two angles of 10 degrees will be formed.

The points (1, 3) and (−3, 7) lie on a line. where does the line cross the x-axis?
Anastasy [175]
First, we find the equation of the line...

(1,3),(-3,7)
slope = (7 - 3) / (-3 - 1) = 4/-4 = -1

y = mx + b
slope(m) = -1
use either of ur points.... (1,3)...x = 1 and y = 3
now sub into the formula and find b, the y int
3 = -1(1) + b
3 = -1 + b
3 + 1 = b
4 = b
so the equation for this line is : y = -1x + 4 which is usually written as :
 y = -x + 4

Now...to find where the line crosses the x axis (or the x intercept)...we sub in 0 for y and solve for x

y = -x + 4
0 = -x + 4
x = 4... so ur x intercept (where the line crosses the x axis) is : (4,0)

A farm stand wants to sell fruit to local grocery stores in packages with baskets of strawberries, worth $7 apiece, and baskets
8090 [49]

Answer:

number of baskets of strawberries in each package = 21

number of baskets of raspberries in each package = 9

Step-by-step explanation:

Let x = number of baskets of strawberries in each package.

Let y = number of baskets of raspberries in each package.

Baskets of strawberries worth $7 apiece, and baskets of raspberries, worth $11 apiece. The cost of the each package is $246. This means

7x + 11y = 246 - - - - - - - - -1

The owner wants each package to include 30 baskets total. This means

x + y = 30

Put x = 30 - y in equation 1

7(30-y) + 11y = 246

210 - 7y + 11y = 246

-7y + 11y = 246 - 210

4y = 36

y = 36/4 = 9

x = 30-y = 30-9

= 21

Holly made a number using these digits 4 8 5 the hundreds digit is greater than 4 Holly’s number is odd what number did holly ma
Alex17521 [72]
So we can first assume the number is _ _ _. and we know that the hundreds is greater than 4. so the hundred should be either 8 or 5. and the number is odd. which means the ones should be an odd number, in this case, only 5 is odd. so 5 should be placed at ones. lasf, 4 should be placed at tens.


the number would be 8 4 5.
