Answer 1

Answer:

Answer:

the answers are

m<1 = 65

m<2=25

m<3=115

Step-by-step explanation:

first of all in the triangle

the angles are 90, 25 and an unknown(let be x)

so,

triangle=sum of all sides

180=90+25+x

180-115=x

x=65

now,

to find m<2

m<2+65=90

m<2=25

then,

to find m<1,

m<1+m<2=90(sum of 2 opp interior angle equals the exterior angle)

or, m<1+25=90

m<1=65

again

for m<3,

180(straight line) +m<2 +m<3 =360(complete turn)

180+25+m<3=360

m<3 =360-205

m<3 =155

When you add 18 to 1/4 of a number you get the number itself

Answers

-- Then when you only have 1/4 of the number, 18 must be
the missing 3/4 of it.

-- If 18 is 3/4 of it, then each quarter of it is 6 .

-- When you have all 4 quarters in the same place, if each one is 6,
then the whole thing must be 24.

Simplify 3 1/5 + 4/16

Help asap!!!

Answers

Answer:

3 1/5 = 16/5

4/16 = 1/4

simply and find a common denominator, in this case it is 20. Multiply the top and bottom by the same number, to get the bottom to twenty. So, to get 5 to 20, you must multiply by 4, so you have to multiply the top by 4 too, which is 64. Do the same for the next fraction.

16/5 = 64/ 20 (both x4)

1/4 = 5/20 (both x5)

now add

64/20 + 5/20 = 69/20

69/20 is the final answer because it cannot be simplified futher.

D= 11/5(p-15)

solve for p.

Answers

Answer: The required solution for p is $p=(11+75D)/(5D).$

Step-by-step explanation: We are given to solve the following equation for the unknown variable p :

$D=(11)/(5(p-15))~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To solve the given equation for p, we must find the value of p in terms of D.

From equation (i), we have

$D=(11)/(5(p-15))\n\n\n\Rightarrow D=(11)/(5p-75)\n\n\n\Rightarrow D(5p-75)=11\n\n\Rightarrow 5Dp-75D=11\n\n\Rightarrow 5Dp=11+75D\n\n\Rightarrow p=(11+75D)/(5D).$

Thus, the required solution for p is $p=(11+75D)/(5D).$

D=11/5p-33
11/5p=D+33
p=5/11D+15
