Twin​ brothers, Billy and​ Bobby, can mow their​ grandparent's lawn together in 53 minutes. Billy could mow the lawn by himself
podryga [215]
5353 minutes = 89.22 hours
Maybe the figures should be 53 and 20??

Let's let Billy = A
The formula to use for work problems is
Time = (A*B) / (A+B)

53 = ( (A +20)* A) / (A +20 + A) )
53 = ( A^2 + 20A ) / (2A + 20)
A^2 + 20A -106A -1060
A^2 -86A -1060
A = 96.935

Express the equation x = 10 and y = -3 as a linear equation in two variables
34kurt

Answer:

For x = 10:

x + 0y - 10 = 0

For y = - 3:

0x + y + 3 = 0

Step-by-step Explanation:

Before we start let's recall the formula for the linear equations.

ax + bx = c

So first let's solve for x=10:

x = 10

Move 10 to the other side.

x - 10 = 0

As there is no y given we will simply write 0y.

x + 0y  - 10= 0

Now let's solve for y=-3:

y =  - 3

Move -3 to the other side.

y + 3 = 0

As there is no x given we will simply write 0x.

0x + y + 3 = 0

If this answer helped you, give this answer a heart, rate it and if you could then please mark it brainliest. Thanks!

Find the value of a in the picture
Assoli18 [71]

Answer:

The measure of arc a is 86°

Step-by-step explanation:

we know that

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.

so

86°=(1/2)[arc c+arc a]

see the attached figure with letters to better understand the problem

In this problem

Triangles ABO and CDO are congruent by SSS postulate theorem

∠AOB=∠COD

∠AOB=arc a -----> by central angle

∠COD=arc c -----> by central angle

therefore

The measure of arc a is congruent with the measure of arc c

arc a=arc c

so

86°=(1/2)[2arc a]

86°=[arc a]

arc a=86°
