Answer:

awnser one is 7 and question 2 is -10

Step-by-step explanation:

−12−2−−55=? question one

In the first fraction, the negative numerator and negative denominator cancel each other.

Since the the second fraction is negative and you are subtracting, remove the negative sign and switch the operation to addition.

The equivalent equation is

122+55=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(12/2, 5/5) = 10

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(122×55)+(55×22)=?

Complete the multiplication and the equation becomes

6010+1010=?

The two fractions now have like denominators so you can subtract the numerators.

Then:

60+1010=7010

Since 70 divided by 10 equals 7 then,

7010=7

Therefore:

−12−2−−55=7

Question 2

−81+6−3=?

In the second fraction, move the negative sign from the denominator to the numerator and the value remains the same.

The equivalent equation is

−81+−63=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(-8/1, -6/3) = 3

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(−81×33)+(−63×11)=?

Complete the multiplication and the equation becomes

−243+−63=?

The two fractions now have like denominators so you can add the numerators.

Then:

−24+−63=−303

Since -30 divided by 3 equals -10 then,

−303=−10

Therefore:

−81+6−3=−10

Solution by Formulas

Apply the fractions formula for addition, to

−81+6−3

and solve

(−8×−3)+(6×1)1×−3

=24+6−3

=30−3

=−10

A line segment is drawn from (+6, +4) to (+9, +4) on a coordinate grid.Which explains one way that the length of this line segment can be determined?

A.
Add 9 + 6.

B.
Add 6 + 6.

C.
Subtract 9 – 6.

D.
Subtract 6 – 6.

Answers

Letter c. add 9-6 explains one way that the length of this line segment can be determined. In order to verify this for yourself, you can plot these two point on a Cartesian coordinate plane and manually measure the length of the line. Mathematically, the length of a line may be calculated by the distance formula given as: sqrt[(x2-x1)^2+(y2-y1)^2]

The slope intercept form is
y = mx + c
4x + 9y = -36

We should rearrange to keep it in y = mx + c order
And therefore we do this:

take the x to the other side

9y = -4x - 36

Divide both sides by 9 to be y alone

$(9y)/(9)$ = $(4x - 36)/(9)$
9 and 9 cancels out

y = $-(4x)/(9)$ - 4

The first option is the answer

What is the solution to the following system of equations?y = -x2 - 5x - 4
y = -x2 + 9x - 18 (2 points)

(-1, -10)
(1, -10)
(-1, 10)
(1, 10)

Answers

The answer is (1,-10)

You solve this by equating the two equations:
-x2 -5x -4 = -x2 +9x -18
-14x = -14
x =1

You then substitute 1 to either of the equations to find y:
y = -(1)2 -5(1) -4
y = -10

Therefore, the solution is (1,-10)

Answer:

It's B

Step-by-step explanation:

10 is 5% of what number

Answers

We can use proportion to get the result
10 ----------- 5%
x ------------- 100%
Crossmultiply proportion

5*x=10*100
5x=1000 /:5 divide both sides by 5
x=1000:5
x=200 - its the answer

$p\%=(p)/(100)\n\n5\%=(5)/(100)=0.05\n\nx-the\ number\n\n5\%\ of\ the\ number\ (x)\Rightarrow 0.05x\n\nThe\ equation:\n\n0.05x=10\ \ \ \ \ |divide\ both\ sides\ by\ 0.05\n\nx=(10)/(0.05)\n\nx=(1000)/(5)\n\n\boxed{x=200}\leftarrow ANSWER$
