Answer:

  • A, B, C, D

Step-by-step explanation:

  • −5.93 + (−8.62) + 5.93 =
  • −5.93 - (8.62 - 5.93) =         B
  • −(5.93 + 8.62) + 5.93 =       C
  • −5.93 −8.62 - (- 5.93) =       D
  • -8.62                                    A

ANSWER:

[a] – 8.62

[b] – 5.93 –(8.62 – 5.93)

  • – 5.93 – 8.62 + 5.93
  • – 8.62

[c] –(5.93 + 8.62) + 5.93

  • – 5.93 – 8.62 + 5.93
  • – 8.62

[d] – 5.93 – 8.62 –(–5.93)

  • – 5.93 – 8.62 + 5.93
  • – 8.62

[e] – 5.93 –(8.62 + 5.93)

  • – 5.93 – 8.62 – 5.93
  • – 8.62 – 11.86
  • – 20.48

So, <u>Correct choice</u> - [a] ; [b] ; [c] ; [d].

O is the centre of the circle, EF is a tangent, angle BCE=28 degrees, angle ACD=31 degrees.
Yuki888 [10]

Answer:

a. 28˚

b. 76˚

c. 104˚

d. 56˚

Step-by-step explanation

a. because angle between tangent and chord is equal to the angle(s) in alternate segment.

b. because angles in triangles add up to 180˚, 180-28=152 and because isosceles triangle, 152/2=76˚

c. because angles in triangles add up to 180˚ and opposite angles in a cyclic quadrilateral add up to 180˚, 31+76=107, 180-107=73, 73-28=45, angles in triangle so 180-(31+45)=104˚

d. 28*2=56˚ because angles at circumference are half angles at centre

Oksanka [162]
14 inch document....it is reduced to 0.6 times as long...
14 * 0.6 = 8.4 inches long
it is too small, so he enlarges it 1.4 times...
8.4 * 1.4 = 11.76 inches <===

Write a two step equation involving division and addition that has a solution of x = 25
Tamiku [17]
Start with the solution
x=-25
use the reverse of what they asked
they wanted division and addition
we use multiplication and subtract

ok
x=-25
we can use subtraction and multiplication in any order
minus 10 from both sides
x-10=-35
multiply both sides by 4
4(x-10)=-140
4x-40=-140 is a possible equation

Mikela claims that the sum of any two numbers is greater than the larger of the two numbers. Jim claims that the sum of any two
qaws [65]

<u>ANSWER:  </u>

The statement of Jim is correct

<u>SOLUTION:  </u>

Given statements are  

Mikela claims that sum of any two numbers is greater than the larger of the two numbers.  

Jim claims that the sum of any two natural numbers is greater than the larger of the two numbers.

Let a,b be the two numbers and a is the greatest of a and b

According to the mikela statement = a + b > a

b > a – a

b > 0

Here, we got an condition that b > 0, but it may not be true always.  

Above condition fails when b is either 0 or negative number.  

Jim - sum of any two natural numbers is greater than the larger of the two numbers.

Let a,b be the two natural numbers. And a is the greatest of a and b

According to the jim statement  =  a + b > a

b > a – a

b > 0

Here, we got an condition that b > 0,

And this statement will always be true because b is an natural number, so it will be greater than 0.

Hence jim’s statement is true.

You had a credit card balance of $186, then you purchased books for $174. CDs for $35, and a pair of shoes for $99 with the cred
Tems11 [23]
You have $284 in your credit card balance. 186-174= 12. 99+35= 134 and then 12-134= -122. So 406-122= 284.
