Question 14(multiple choice worth 1 points) (07.06 mc) an unknown number x is at most 30. which graph best represents all the values of x? number line graph with closed circle on 30 and shading to the right. number line graph with closed circle on 30 and shading to the left. number line graph with open circle on 30 and shading to the left. number line graph with open circle on 30 and shading to the right

Number line graph with closed circle on 30 and shading to the left

Step-by-step explanation:

we know that

The algebraic expression of the phrase " An unknown number x is at most 30" is equal to

The solution is the interval ------> (-∞,30]

All real numbers less than or equal to 30

Number line graph with closed circle on 30 and shading to the left

see the attached figure

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
