Answer:

Step-by-step explanation:

Two angles are supplementary when their sum is 180

∠AXB + ∠BXC = 180° {Supplementary angles}

8x + 10 + 2x - 20 = 180

Add the like terms

10x - 10 = 180

10x = 180 + 10

10x = 190

x = 190/10

x = 19°

∠AXB = 8x + 10

= 8 * 19 +10

= 152 + 10

∠AXB = 162

Answer:

180 degrees

Step-by-step explanation: the measure of angle AXB is ( a + a ) and the sum of the measured angles AXB and BXC = 180 , so a + ( a + a) = 180.

both these angles add up to be 180 degrees because they are both supplementary angles they both share the sides of x and b.

if it confuses you, just use a bit of repeated addition and multiplication

for example : 30 + 30 + 30 + 30 + 30 = 5 x 30 which equals to 150

because you add 30 , 5 times .

Two buses leave a corner at the same time. One bus goes uptown at a constant rate of 25 mph, the other downtown at a rate of 15

vlada-n [284]

The rate of separation = 25 + 15 = 40 mph

speed = distance / time

40 = 30 / t

t = 30/40 hour = 45 minutes

Its C.

Studentka2010 [4]

Answer:

5/6

Step-by-step explanation:

Find the lowest common denominator between the 10 and 12.

10 and 12 have the lowest common denominator of 2

10/2=5

12/2=6

So 5/6 is the lowest term of 10/12

Lucy had math and reading homework tonight. Lucy can solve each math problem in 5 minutes and she can read each page in 2.5 minu

drek231 [11]

Answer:

$x=18,y=6$ , graph is there for reference.

Step-by-step explanation:

Given,

$x$ is the number of math problem Lucy solved.

$y$ is the number of pages she read.

She can do each math problem in $5$ minutes, therefore she can solve $x$ number of questions into $5 \times x=5x$ minutes.

She can read each page in $2.5$ minutes, therefore she can read $y$ pages in 2.5y minutes.

As per given detail,

$5x+2.5y=105$ equation 1.

And,

It is given that number of math problems Lucy solved is 3 times the number of pages she read.

$x=3y$ equation 2.

We need to find $x$ and $y$ intercept of each of the equation to graph them.

For $x-intercept$ put y=0

We will get $x=\frac{105}{5} =21$

Thus the point is $(21,0)$

Let us find $y-intercept$ by assuming $x=0$

we get $y=\frac{105}{2.5} =42$

Thus the point is $(42,0)$

Join these two points.

Similarly considering the other equation $x=3y$

Here x-intercept would be at $y=0$

We will get $x=0$

Thus the point is $(0,0)$

Let us assume on more point, say $x=30$ , we get $y=10$

Thus the point is $(30,10)$

Join these two points.

We will get a point of intersection at $(18,6)$

Thus $x=18$ and $y=6$

Find the surface area of this rectangular prism 4ft, 8ft, 2ft

Whitepunk [10]

Answer:

112ft^2

Step-by-step explanation:

A = 2(wl+hl+hw)

A = 2[(4)(8)+(2)(4)+(2)(8)]

A = 2(32+8+16)

A = 2(56)

A = 112
