Answer:

add 104 and 22 and then subtract that from 180. thats the answer to x.

then add 104 to 22 plus 19 and then subtract that answer minus 180. thats the answer to z

once you get z you can add z and 19 than subtract 180 again to get y

The sum of 3 consecutive odd numbers is 183 whats the second number im this sentence

Naddik [55]

Answer:

The second number is 61

Step-by-step explanation:

It's implied that the first integer is odd.

Since the consecutive intergers are odd, use an equation that looks like this:

(x+2) + (x+2) + (x+2) = 183 and simplify

*If you add 2 to an odd number, you get the next odd number. That's why I used 2*

3x + 6 = 183 → 3x = 177 → x = 59 which means the first integer is 59. The consecutive integers is 59, 61, 63.

Write the point slope form of the equation of the line using the point (-4,-2)

Gre4nikov [31]

Answer:

$y + 2 = \frac{5}{4} (x + 4)$

Step-by-step explanation:

1) First, find the slope of the line. Take two points the line intersects and use them for the slope formula, $\frac{y_2-y_1}{x_2-x_1}$ . We already know the line intersects (-4, -2). Just choose any one of the points you can see the line intersecting (in this case, I chose (0,3)) and plug in its values, too. Then solve:

$\frac{(3)-(-2)}{(0)-(-4)} \\\frac{3+2}{0+4} \\\frac{5}{4}$

So, the slope is $\frac{5}{4}$ .

2) Now that you have the slope, plug in values for the point-slope formula, $y - y_1 = m (x - x_1)$ . In order to write a linear equation with it, the $x_1$ , $y_1$ , and $m$ have to be substituted for with real values. The $m$ represents the slope - which means that we should place $\frac{5}{4}$ there. The $x_1$ and $y_1$ represent the x and y values of a point - and the questions wants us to use (-4, -2), so substitute -4 for $x_1$ and -2 for $y_1$ :

$y-(-2) = \frac{5}{4} (x - (-4))\\y + 2 = \frac{5}{4} (x + 4)\\$

Thus, the answer is $y + 2 = \frac{5}{4} (x + 4)$ .

In rhombus EFGH below, EF= 13m and DG = 5m, Find the area of the rhombus.

Mariana [72]

Answer:

the correct answer is 120 square meters

Step-by-step explanation:

DG is a half diagonal and it intersects with the other diagonal at 90°. So it forms a right angle triangle. Using Pythagoras theorem

13^2-5^2=d^2

169-25=d^2

144=d^2

d=√144

d=12

so the other half diagonal is 12m

the two diagonals will be 2×5 and 2×12

the two diagonals will be 10m and 24m

area of a rhombus=1/2d1d2

area of the rhombus= 1/2×10×24

area of the rhombus=120 square meters

A basket contains four apples three peaches and four pears . you randamoly eat three pieces of fruit . the first one you want is

sasho [114]

P(apple first) = 4/11
P(peach second) = 3/10
P(peach third) = 2/9
$P(desired\ selection)=\frac{4}{11}\times\frac{3}{10}\times\frac{2}{9}=\frac{4}{165}$
Choice A is correct.

Misha and her cousin Darius made muffins for the Clark family reunion. Misha made 17 more muffins than Darius. Dark is made 56 m

VMariaS [17]

Answer:

Number of muffins per plate.

Step-by-step explanation:

We are given the following in the question:

Let x be the number of muffins made by Dark

Then, number of muffins made by Misha =

$x + 17$

For x = 56

Muffins made by Dark = x = 56

Muffins made by Misha =

$x + 17 = 56 + 17 = 73$

Total number of muffins =

$56 + 73 = 129$

Total number of plates = 12

Number of muffins on each plate =

$=\dfrac{\text{Total number of muffins}}{\text{Total number of plates}}=\dfrac{129}{12} = 10.75\approx 11$

Thus, there were approximately 11 muffins on each plate.

Thus, the unit of this problem is number of muffins per plate.
