1) m<DCB = <D + <C + <B

180 = 25 + 90 + <C  (Angle Sum Property)

180 = 115 + <C

180 - 115 = <C

65 = <C

-19 to -15 would be a positive 4 difference

19 to 15 = 4 this would be a -4 difference

3 to 7 is a positive 4 difference

-3 to 7 is a difference of 10

so there is 1 with a -4 difference
 answer is B.

Need help please???
dedylja [7]

Answer:

y= \frac{3}{5}x -\frac{26}{5}

Step-by-step explanation:

x₁    y₁                     m= slope

(2, -4)                     point-slope equation: y - y₁ = m( x - x₁)

y-(-4) = \frac{3}{5}( x - 2)

y + 4 = \frac{3}{5} x - \frac{6}{5}

y = \frac{3}{5}x - \frac{6}{5} - \frac{20}{5}

y = \frac{3}{5} x - \frac{26}{5}

Can anyone help me please and explain this: Write "60 pounds for $6.60" as a unit rate per ounce to the nearest tenth. 1 pound=
VMariaS [17]
If the rate is 60 pounds for $6.60 and we need to convert it to a unit rate per ounce, you will think of it as $6.60 for 60 pounds instead.

Divide to get a unit rate per pound.

$0.11 per pound

To convert this to an amount per ounce Change the rate to say $0.11 per 16 ounces(this means the same).

Divide 0.11 by 16 to get 0.006875 or $0.007 or 0.7 cents per ounce. Choice D but it should say per ounce, not per pound.

What’s the slope of the line
Murrr4er [49]
Slope is rise over run or vertical change over horizontal change or change in y over change in x. (All 3 mean the same)

Since the vertical change from one point to another is 14/4 or 7/2, that is the slope ... ps that’s not a line, it’s a line segment.

Can you pls help <br> 5+4-(8*3-22)^4*4<br> pls help you get 25 points
Zina [86]

Answer:

5 + 4 - (8 * 3 - 22)⁴ * 4 = -55

Step-by-step explanation:

5 + 4 - (8 * 3 - 22)⁴ * 4

Follow PEMDAS which states you need to do equations in the order of:

Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.

Knowing this, simplify inside the parenthesis by multiplying 8 and 3 first.

5 + 4 - (24 - 22)⁴ * 4

Now subtract 22 from 24 inside the parenthesis.

5 + 4 - (2)⁴ * 4

Since we are done with parenthesis, move on to the next part of PEMDAS which says to do exponents next. Take 2 to the power of 4.

5 + 4 - 16 * 4

Now that we are done with exponents, move on to the next part of PEMDAS which says to multiply/divide next. Multiply -16 and 4.

5 + 4 - 64

Now that we are done with multiplication/division, move on to the last part of PEMDAS which says to add/subtract. Add 5 and 4.

9 - 64

Finally, subtract 64 from 9 to get:

-55.
