Answer:

16.30

Step-by-step explanation:

16.29(7) seven is more than 5 so you add 1 to the number behind which is 9 so 29+1=30

Answer:

Step-by-step explanation:

15 ≤ x-2

Answer:

A and B, but I’m gonna explain it the best I can too.

Step-by-step explanation:

5.75 divided by 1.15 is the same as answer A, since all you are doing is taking away the periods, making it whole numbers.

Again 5.75 divided by 1.15 is the same as B as well, Since it is the same just without the periods and an added zero at the end of each.

This Is so that they are both all equivalent by being whole numbers, but whatever you do to one numbers in the expression that you think is the answer you have to do to the other numbers in the expression

they have to add up completely the same.

Answer:

An altitude of a triangle is a segment from a vertex of the triangle, perpendicular to the side opposite that vertex of the triangle.

Step-by-step explanation:

Answer:

number 4 because a triangle is only concidered a triangle when it has an area of 180 degrees

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

distributive property

Answer:

I would say A

Step-by-step explanation:

it's A since 5y times 2 which is 10y and 3 time 2 is 6 and its still equivalent to (5y - 3) times 2 so it's 10y - 6

Answer:

Volume=(length)^3

V= (15×15×15)mm^3 = 3375mm^3

Answer:

Easy... its 39.4

Step-by-step explanation:

Cirumference is the lenght all the way around the circle

while radius is only half the circle so you just divide the cirumference by 2 to get half.

Answer:

w = 8

Step-by-step explanation:

–9 = –3(w − 5)

-3(w - 5) = -9

w - 5 = 3

w = 5 + 3

w = 8

Answer:

hello! have a good day

w = 8

Answer:

8544

Step-by-step explanation:

I multiplied them all 8 x 8.9 x 15 x 8 = 8544

Answer:

your question is unclear

Step-by-step explanation:

x+2y=4

-x -x

2y=4-x

divide by 2 to get y by it's self

y=2-(1/2x)

x+2y=4

-2y -2y

x=4-2y

i don't know if u want me to help u with the second one but i did it the first one

Answer:

the water is leaking at a rate of 3/4 a gallon per hour

Step-by-step explanation:

we know this because rate of change is change in y over change in x and as y goes up 3 x goes up 4 so the rate of change is 3/4

[tex]360 - 140 - 62 - 85[/tex]

[tex] = 73 \: degrees[/tex]

the sum of the angles in a quadrilateral is 360° so just subtract the angles you have with the total to find the missing angle.

Answer:

73°

Step-by-step explanation:

The angles add to 360 hope this helps

Answer:

1/4 of 10

Step-by-step explanation:

1/4 of 10 is equal to 1*10/4

[tex] \frac{1}{4} \: of \: 10[/tex]

//

[tex]10 \div 4 = 2.5[/tex]

[tex] \frac{1}{4} \: of \: 10 = 2 \frac{1}{2} = 2.5[/tex]

Answer:

r (-2)= -(-2)-7

=+2-7=-5

Answer:

Step-by-step explanation:

B=90-27=63 degrees

AC=12/(tan27)=23.6

AB=12/(sin27)=26.4

Given :

Measure of angle 7 = 60°

Angle 1 and angle 7 are corresponding angles, so their values will be equal.

Which means :

Angle 1 = 60°

Thus, the measure of angle 1 = 60°

Therefore, the correct option is (A) 60

Answer:

See below.

Step-by-step explanation:

x + 2 = x + 2 ⇒ Infinitely Many Solutions

3x + 1 = 3x - 10 ⇒ 1 ≠ -10 ⇒ No solutions

x + 4 = 2x + 4 ⇒ 4 = x + 4 ⇒ 0 = x ⇒ One solution

the common RATIO is 4

Answer:

m=-3

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

Slope = Rise/Run

We can find the amount between 7 and -5 as 12, and -2 and 2 as 4.

Then we can do rise/run and 12/4

Which would divide into 3.

ANd because we can see the x increases as the y decreases, we can find that it's a negative slope.

Answer:

The two lines 'm' and 'n' are parallel

Step-by-step explanation:

Explanation

Given that the line 'm' points (3,15) and (10,9)

The slope of the line 'm'

                = [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1} } = \frac{9-15}{10-3} = \frac{-6}{7}[/tex]

Given that the line 'n' points (2,9) and (9,3)

The slope of the line 'n'

             = [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1} } = \frac{3-9}{9-2} = \frac{-6}{7}[/tex]

The slope of line 'm' = The slope of  line 'n'

Both slopes of the lines are equal

∴ The two lines are parallel

Answer:

x = 7, y = 2

Step-by-step explanation:

x= 4y -1

since x is by itself 4y-1 will substitute for x in the other equation x+2y=11

it will become 4y-1+2y=11

+1 +1

add one to both sides since is doesn't have a variable.

it will become 4y+2y= 12 now add 4y+2y

becomes 6y=12

_ _

6 6

divide by 6 on each side and you get y=2.

now x=4(2)-1 you will substitute y into the first equation.

x=8-1 subtract 8 from 1 to get 7.

x=7

y=2

Answer:

slope= -3

y-intercept= 6

Step-by-step explanation:

1. Approach

To solve this problem, one needs the slope and the y-intercept. First, one will solve for the slope, using the given points, then input it into the equation of a line in slope-intercept form. The one can solve for the y-intercept.

2.Solve for the slope

The formula to find the slope of a line is;

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where (m) is the variable used to represent the slope.

Use the first two given points, and solve;

(1, 3), (2, 0)

Substitute in,

[tex]\frac{(0)-(3)}{(2)-(1)}[/tex]

Simplify;

[tex]\frac{-3}{1}\\\\=-3[/tex]

3. Put equation into slope-intercept form

The equation of a line in slope-intercept form is;

[tex]y = mx + b[/tex]

Where (m) is the slope, and (b) is the y-intercept.

Since one solved for the slope, substitute that in, then substitute in another point, and solve for the parameter (b).

[tex]y=-3x+b[/tex]

Substitute in point (3, -3)

[tex]-3=-3(3)+b\\-3 = -9 + b\\6 = b[/tex]
