Answer:

x=-10

Step-by-step explanation:

3=-(4x+7)+3x

move all terms to the left:

3-(-(4x+7)+3x)=0

calculate terms in parentheses: -(-(4x+7)+3x), so:

-(4x+7)+3x

add all the numbers together, and all the variables

3x-(4x+7)

get rid of parentheses

3x-4x-7

add all the numbers together, and all the variables

-1x-7

Back to the equation:

-(-1x-7)

get rid of parentheses

1x+7+3=0

add all the numbers together, and all the variables

x+10=0

move all terms containing x to the left, all other terms to the right

x=-10

Which of the following numbers is 90 divisible by? 2,3,4,5,6,9,10
Mrac [35]

Answer:

2,3,5,6,9,10

Step-by-step explanation:

To do this, we can look at how each value divides into 90. If it produces a whole number, they will be consider to be divisible

90/2=45\\\\90/3=30\\\\90/4=22.5\\\\90/5=18\\\\90/6=15\\\\90/9=10\\\\90/10=9

This means 4 is the only value that is not divisible into 90

Find the length of the hypotenuse. 45 degree triangle 3 square root of <br><br> 2
stira [4]

Answer:

Hypotenuse = 6

Step-by-step explanation:

Find attached diagram used in solving the question.

The triangle is a 45°-45°-90° triangle meaning it's two legs are equal. The opposite = adjacent

Since we are told to find hypotenuse, it means the length given = opposite = adjacent = 3√2

Hypotenuse ² = opposite ² + adjacent ²

Hypotenuse ² = (3√2)² + (3√2)²

Hypotenuse ² = 9(2)+9(2) = 18+18

Hypotenuse ² = 36

Hypotenuse = √36

Hypotenuse = 6

Which of the following expressions illustrates the commutative property of addition? 3 + (-7) = (-7) + 3 -4(5) = 5(-4) 4 + (1 +
umka2103 [35]
By definition, we have to:

 In mathematics, the commutative property or commutativity is a fundamental property that has some operations according to which the result of operating two elements does not depend on the order in which they are taken.

 This is fulfilled in ordinary addition and multiplication: the order of the addends does not alter the sum, or the order of the factors does not alter the product.

 We have then, that the commutative property of the addition is:
 3 + (-7) = (-7) + 3

 Answer:
 
An expression that illustrates the commutative property of addition is:
 
3 + (-7) = (-7) + 3

Elena-2011 [213]

Camille spent 22 minutes and 30 seconds opening presents.

Since Camille had a very fun birthday party with lots of friends and family attending, and the party lasted for 3 hours, and she and her friends played games for 3/8 of the time, ate pizza and cake for 50% of the time , and spent the remainder of the time opening presents, to determine the amount of time spent opening presents the following calculation must be performed, posing the following linear equation:

Total time - time spent on other activities = time spent opening presents

  • 3 - (3 x 3/8) - (3 x 0.5) = X
  • 3 - 1.125 - 1.5 = X
  • 3 - 2.625 = X
  • 0.375 = X

  • 1 = 60
  • 0.375 = X
  • 0.375 x 60 = X
  • 22.5 = X

Therefore, Camille spent 22 minutes and 30 seconds opening presents.
