The answer is 4
|-6| turns into 6
-6 + 6 +4
sixes cancel out
so you’re left with 4

Answer: -6 +|-6| + 4 = 4 (the opposite is -4)

3 · -|5| - (72 ÷ 12) = -21 (the opposite is 21)

16 ÷ (-2 + 4) - 5 · | -3 | = -7 (the opposite is 7)

Ruth works at a farmer's market and gets paid $50. she also gets paid $0.65 for each jar of jelly "j" she sells. which equation

34kurt

Answer:

Step-by-step explanation:

Ruth's salary is s(j), where s represents salary and j the number of jars she sells.

At the very beginning, she receives $50. Only answer 'd' could be correct.

But also, the equation has the variable part 0.65j, or

$0.65j, which is directly proportional to the unit price of the jars of jelly.

Summing up the fixed and variable parts, we get

s = $50 + ($0.65j), or s = $50 + ($0.65/jar)j This is Answer D.

Determine the measurement of the unknown angle measures in the given figure.

Andrei [34K]

Answer:

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Please I have my final now can someone help me with this fast

Mariana [72]

Answer:

option B

Step-by-step explanation:

Given :

$y = \frac{2}{3}x + 3\\\\y = \frac{5}{2}x + \frac{7}{2}\\\\$

Step 1 : simplify the equation :

$3y = 2x + 9\\\\2y = 5x + 7\\$

Step 2: Arrange the terms :

$2x - 3y = - 9\\\\5x -2 y = -7$

Step 3 : Solve for x and y :

2x - 3y = - 9 ------ ( 1 )

5x - 2y = - 7 --------- ( 2 )

_____________________

( 1 ) x 5 => 10x - 15y = - 45 ---------- (3 )

( 2) x 2 => 10x - 4y = - 14 ----------- (4 )

_______________________

( 3 ) - ( 4 ) => 0x - 11y = - 31

- 11 y = - 31

$y = \frac{31}{11}$

Substitute y in ( 1 ) :

2x - 3y = - 9

$2x - 3 (\frac{31}{11}) = - 9\\\\2x = -9 + 3(\frac{31}{11})\\\\2x = - 9 + \frac{93}{11}\\\\2x = \frac{-99 + 93}{11} \\\\2x = \frac{-6}{11} \\\\x = \frac{-6}{2 \times 11} = -\frac{3}{11}$

Therefore the solution to the sytem is $( - \frac{3}{11} , \frac{31}{11})$

The solution of the system of equation is a point which lies

on the both the lines.

Option A : False , It says the solution lies above one of the given line.

But the solution of the system of equation always lies on

both the line.

Option B : True , says the solution is a point on the coordinate plane.

Option C : False, because if the solution is on the x-axis , then

the y coordinate in the solution would be zero.

But it is not zero.

Option D : False , the solution is the point where both the lines intersect.
