How many solutions can be found for the equation 3y + 5 − 2y = 11?

1 answer:

7 0

We can solve the equation to find it's number of solutions, but we already know it only has 1 solution because it is a linear equation (y is raised to the first power).

3y + <span>5 − 2y = 11
</span>y + <span>5 = 11
</span>y = 6

This confirms that there is only 1 solution.

D is answer.
Perimeter is 2x +3x +2x + 3x = 10x where x is unknown factor of distance.
So P = 10x
Velocity is 12 km/hr = .2 km/min
P =1.6 Km = 10x
x= .16 Km 3x = .48 km, 2x=.32 km
Area = .48 X .32 Km^2
= 153600 m^2

9.50 + (2.20)r

For example if he fixed 3 watches

9.50 + (2.20)3

We plug in 3 for r and he makes 6.60 extra.

A. find the value of a. B. Find the value of the marked angles.

Marat540 [252]

The marked angles are opposite angles, and as such they have the same measure. So, we have

$6a+11 = 2a+83$

Subtract 2a and 11 from both sides to get

$4a = 72$

Divide both sides by 4 to get

$a = \dfrac{72}{4} = 18$

Now that we know the value of a, we can compute the measure of the angles. We can also verify that the solution we found is correct by verifying that both expressions actually give the same result:

$6a+11 = 6\cdot 18 + 11 = 119$
