This would be D:).... C = the number of cards his brothers each get.

Ada is putting autographed baseballs in a display case. The display can hold 28 baseballs, and there are already 17 baseballs in

krok68 [10]

Answer:

You can use the equation " 17 +b = 28 " to check is she's right because 17 +b has to be 28 baseballs.

Step-by-step explanation:

Sorry for that answer but what I meant was that 17 + b (How many baseballs can be added) must be 28. Now you can subtract both sides by 17 to isolate b by itself. When you do that you get b= 11. So you can add 11 more baseballs instead of 9, therefore she is wrong.

You can check this by putting 11 in for b in the equation. 17+11=28. This is correct.

Hopefully this helped you.

What is the reflection of image p(0,0) after two reflections first across x=-3 and

pochemuha

<span>P (0, 0) across x = -3 will change the x value. From 0 to -3 which is 3 units down, so the reflection will be another 3 units down ( points are the same distance from the reflection line) so the new x-value is -6 now just do the same thing for the y-value and you will get an image of P¹ ( -6, -6 ) </span>

What is the area of a circle with a diameter of 37 inches?

krek1111 [17]

Hello!

To find the area of a circle you use the equation

$\pi r^{2}$

r is the radius which is half the diameter

$\pi 18.5^{2}$

Square 18.5

$\pi *342.25$

Put this into the calculator and you get the answer of about 1075.21

The answer is about 1075.21

Hope this helps!

Find the value of x. Then find the measure of each labeled angle

timurjin [86]

Answer:

x = 111°

x° = 111°

(x-42)° = 69°

Step-by-step explanation:

Any polygon with *n* number of sides has an interior angle sum of (n-2) × 180°.

Therefore this right trapezoid must have an interior angle sum of 360° because

a trapezoid has 4 sides → n = 4 →

(n-2) × 180° = (4-2) × 180° = 2 × 180° = 360°

Because we are given a 90 degree angle with a set of parallel sides, the angle above that must also be a right angles well so these will total 180°.

The last two angles are given by the two expressions x°, and (x-42)°. Because we know the sum of these angles which are 360° we can create the following equation from these angles and solve!

180° + 2x - 42° = 360°

(Group the constants / numbers without a variable ; associative property of addition)

180° - 42° + 2x = 360°

(Find the total value of the constants)

138° + 2x = 360°

(subtract 138° from both sides to isolate 2x on the left side ; subtraction property of equality)

138° - 138° + 2x = 360° - 138°

(Work out the value of the constants again)

2x = 222°

(divide by 2 on both sides to cancel out the coefficient of 2 in 2x to get x by itself ; division property of equality)

2x / 2 = 222° / 2

(Simplify the two expressions)

x = 111°

_____________________

To find the measure of the x expressions, just substitute x = 111° into the expressions and simplify to find the measure!

So:

x = 111° → x° = 111°

x = 111° → (x-42)° → (111 - 42)° = (69)° →

(x-42)° = 69°
